A bird watcher on a cliff spotted a kingfisher 7 m above him.
Earlier he had seen it 11m below. What was the kingfisher’s
change in altitude?
Answers
Answer:
18 m
Step-by-step explanation:
11m + 7m is 18m
The final answer is 18m
The change in altitude of the kingfisher is 18 m.
What is the altitude length?The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex.
Suppose the distance above the cliff is represented by a positive integer.
Then the distance below it is represented by a negative integer.
Thus, change in altitude of the kingfisher
= 7-(-11)
= 7+11
= 18 m
Hence, the change in altitude of the kingfisher is 18 m.

Answers
The statement "This does not make sense because the mean and median should lie somewhere to the right of the mode if the distribution is left-skewed" is correct. The correct answer is B
In a left-skewed distribution, the mode is the highest point and it is located to the right of the median, which in turn is located to the right of the mean.
This is because the mean is influenced by extreme values on the left tail, which pull it to the left, whereas the median is unaffected by extreme values and is only determined by the middle value(s) in the data set.
Thus, if the mean, median, and mode are all the same in a left-skewed distribution, this indicates that the data set is either symmetric or approximately symmetric.The correct answer is B

A discrete random variable X has mean μ=28 and standard deviation σ=9. What is the expected value of X? Not enough information to determine. 14 9 28 A manufacturing machine has a 4% defect rate. If 3 items are chosen at random, what is the probability that at least one will have a defect? Round result to four decimal ploces. Recall: P(x is at least one )=1⋅P (none ) P(x>=1)=1⋅P(x=0)
Answers
We find that the probability of at least one defect is approximately 0.1158.
The expected value of a discrete random variable is equal to its mean. Therefore, in this case, the expected value of X is 28.
To calculate the probability that at least one out of three randomly chosen items will have a defect, we can use the complement rule. The complement of "at least one defect" is "no defects." The probability of no defects occurring is equal to the probability of each item being defect-free, raised to the power of the number of items.
Since the defect rate is 4%, the probability of an item being defect-free is 1 - 0.04 = 0.96. Thus, the probability of no defects in one item is 0.96. To find the probability of no defects in all three items, we multiply this probability by itself three times: 0.96^3.
To find the probability of at least one defect, we subtract the probability of no defects from 1: 1 - 0.96^3. Evaluating this expression gives us the probability that at least one item will have a defect.
Calculating this probability, rounded to four decimal places, we find that the probability of at least one defect is approximately 0.1158.

Answers
(a) (6, H, 7) is not a possible outcome because the sum of the two numbers rolled on the number cube cannot be 7 if the first number rolled is 6.
(b) (T, 3, 4) is a possible outcome because the first outcome is tails, the second outcome is 3, and the third outcome is 4.
(c) (6, H, 6, T) is not a possible outcome because the third outcome cannot be both 6 and T at the same time.
(d) (1, T, 1) is a possible outcome because the first and third outcomes are both 1 and the second outcome is tails.
(e) (H, H, 3) is not a possible outcome because the third outcome cannot be 3 if the first two outcomes are both heads.
What is Probability?
Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.
Since each of the three people orders a different flavor, the first person has 6 choices, the second person has 5 choices (since one flavor has already been chosen), and the third person has 4 choices (since two flavors have already been chosen). The total number of outcomes is the product of these numbers:
6 × 5 × 4 = 120
Therefore, there are 120 possible outcomes.
(part 1) There are 10 options for the first digit, 9 options for the second digit (since one digit has already been chosen), and 8 options for the third digit (since two digits have already been chosen). The total number of combinations is the product of these numbers:
10 × 9 × 8 = 720
Therefore, there are 720 possible locker combinations.
(part 2) If you absolutely choose 9 as your first digit, then there are only 9 options for the first digit. The second and third digits can still be any of the remaining 9 digits (since digits cannot repeat). Therefore, the number of possible combinations is:
1 × 9 × 8 = 72
The theoretical probability of getting HH on two coin flips is (1/2) × (1/2) = 1/4 = 0.25. The experimental probability of getting HH after 100 trials is 25/100 = 0.25. Since the experimental probability is equal to the theoretical probability, we can say that the experimental probability of getting HH is equal to the theoretical probability.
The possible outcomes of rolling a standard number cube are 1, 2, 3, 4, 5, and 6. The possible outcomes of flipping a coin are heads (H) or tails (T).

Which approach to probability is exemplified by the following formula? Probability of an Event= Number of favourable Outcomes /Total number of possible outcome A) Classical approach B) Empirical approach C) Subjective approach D) None of the above
Answers
The approach to probability exemplified by the formula Probability of an Event = Number of favourable Outcomes / Total number of possible outcomes is the Classical approach to probability.
The Classical approach to probability is based on the assumption of equally likely outcomes and is often used when dealing with simple and well-defined experiments or situations. It involves counting the number of favorable outcomes (those that satisfy the desired condition) and dividing it by the total number of possible outcomes. This approach assumes that all outcomes have an equal chance of occurring.
In contrast, the Empirical approach involves conducting experiments or observations to gather data and estimate probabilities based on the observed frequencies. The Subjective approach relies on personal judgments or subjective assessments of probabilities based on individual beliefs or opinions.
Therefore, the correct answer is A) Classical approach.

Answers
The given information shows the sample data for estimating the proportion of ice melt ponds in the region with first-year ice: Sample size: 122 Number of ponds with first-year ice: 18 Number of ponds with only multiyear ice: 72 Sample proportion with first-year ice: 0.14754098
The sample size is large enough and the condition n × p ≥ 10 and n × (1 − p) ≥ 10 are met, where n is the sample size and p is the sample proportion. The formula for the 95% confidence interval for the population proportion is:
(p - E, p + E), where E = zα/2 × √(p(1-p)/n)
Here, α = 0.05 and the corresponding zα/2 value can be found from the standard normal distribution table as 1.96.
Hence, the 95% confidence interval is: p - E = 0.14754098 - 0.04727347 = 0.10026751
p + E = 0.14754098 + 0.04727347 = 0.19481445
Rounding to four decimal places, the 95% confidence interval is (0.1003, 0.1948).
Therefore, the correct answer is option B: One can be 90% confident the true proportion of ice melt ponds in the region with first-year ice is within the above interval, though it is probably not 15%.

where Q is the quantity of chocolate demanded, P is the price of chocolate, PA is the price of an apple and Y is income, find:
(i) the own price elasticity of demand for chocolate
(ii) the cross price elasticity of demand (
iii) the income elasticity of demand where P=3,PA =2 and Y=100. Comment on the economic significance of your answers.
Answers
The income elasticity of demand is positive, implying that chocolate is a normal good = 0.037
The demand function, Q = 54−5P + 4PA + 0.1Y.
Where Q is the quantity of chocolate demanded, P is the price of chocolate, PA is the price of an apple, and Y is income.
(i) The own-price elasticity of demand for chocolate, we first need to find the expression for it.
The own-price elasticity of demand can be expressed as:
Own-price elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)Or,E
P = (ΔQ / Q) / (ΔP / P)E P = dQ / dP * P / Q
Let's calculate the own-price elasticity of demand:
EP= dQ / dP * P / Q= (-5) / (54 - 5P + 4PA + 0.1Y) * 3 / 30
= -0.1667
So, the own-price elasticity of demand for chocolate is -0.1667.
(ii) The cross-price elasticity of demand, we must first determine the expression for it.
The cross-price elasticity of demand can be expressed as:
Cross-price elasticity of demand
= (Percentage change in quantity demanded of chocolate) / (Percentage change in price of apples) Or, E
PA = (ΔQ / Q) / (ΔPA / PA)E PA = dQ / dPA * PA / Q
Let's calculate the cross-price elasticity of demand:
EP = dQ / dPA * PA / Q= (4) / (54 - 5P + 4PA + 0.1Y) * 2 / 30= 0.0296
So, the cross-price elasticity of demand is 0.0296.
(iii) The income elasticity of demand can be expressed as:
Income elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in income)Or,E
Y = (ΔQ / Q) / (ΔY / Y)E Y = dQ / dY * Y / Q
Let's calculate the income elasticity of demand: EY = dQ / dY * Y / Q= (0.1) / (54 - 5P + 4PA + 0.1Y) * 100 / 30
= 0.037
The own-price elasticity of demand is negative, meaning that the quantity demanded of chocolate decreases when the price of chocolate increases.
The cross-price elasticity of demand is positive, indicating that chocolate and apples are substitute goods.

Write the equation in standard form for the circle passing through ( – 2,4) centered at the origin.
Answers
To write the equation in standard form for the circle passing through (–2, 4) centered at the origin, we need to find the radius and the center of the circle.
Since the circle passes through (–2, 4), we can use the distance formula to find the radius, which is the distance from the origin to (–2, 4).
The distance formula is given by:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, x1 = 0, y1 = 0, x2 = –2, and y2 = 4. So, the radius is:
radius = sqrt((-2 - 0)^2 + (4 - 0)^2) = sqrt(20) = 2sqrt(5)
The center of the circle is the origin, since the circle is centered at the origin. Therefore, the equation of the circle in standard form is:
x^2 + y^2 = (2sqrt(5))^2 = 20
So, the equation of the circle passing through (–2, 4) centered at the origin is x^2 + y^2 = 20.

What can you say about a sample mean or a sample proportion being about 2 ses away from the population mean or the true proportion? what can you not say?
Answers
When we have a normal model for the sampling distribution, we cannot say that a sample mean or sample proportion is approximately 2 standard errors (ses) away from the population mean or the true proportion.
Instead, we can say that 95% of the sample proportions fall within two standard errors of the population proportion. Similar to this, the percentage of sample proportions decreases as the standard error distance decreases and increases as the standard error distance increases.
Therefore, the standard error distance will be greater than 2 standard errors (ses) if 99% of the sample proportions are within a given standard error distance of the population proportion.

Answers
The correct answer is option D. Above the mean by a distance equal to 1.20 standard deviations .What is z-score? A z-score is also known as the standard score and is used to calculate the probability of a score occurring within a normal distribution's distribution.
It is a measure of how many standard deviations a data point is from the mean. It is denoted by the letter “Z.”Z-score calculation formula isz = (x- μ) / σ Where,
x = Score
μ = Mean
σ = Standard deviation
In this question, the z-score given is 1.20, which means it is 1.20 standard deviations above the mean. Therefore, option D. Above the mean by a distance equal to 1.20 standard deviations is the correct answer to the given question.
A z-score is the number of standard deviations that a data point is from the mean of a distribution. To solve this problem, we'll first need to determine the position in the distribution that corresponds to a z-score of 1.20. The formula for calculating z-score is z = (x - μ) / σwhere z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation. Using this formula, we can solve for the raw score that corresponds to a z-score of 1.20. We know that the z-score is 1.20, so we can substitute that value in for z:1.20 = (x - μ) / σWe also know that the mean is 0 (since z-scores are calculated based on a standard normal distribution with a mean of 0 and a standard deviation of 1), so we can substitute that value in for μ:1.20 = (x - 0) / σSimplifying the equation,
we get: 1.20σ = x Now we know that the raw score is equal to 1.20 standard deviations above the mean. So the correct answer is D. Above the mean by a distance equal to 1.20 standard deviations.

The new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees are approximately (4.993, 2.048).
To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:
x' = x * cos(theta) - y * sin(theta)
y' = x * sin(theta) + y * cos(theta)
Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.
Converting the angle of rotation from degrees to radians:
theta = 5 degrees * (pi/180) ≈ 0.08727 radians
Plugging in the values into the rotation formula:
x' = 5 * cos(0.08727) - 2 * sin(0.08727)
y' = 5 * sin(0.08727) + 2 * cos(0.08727)

Let f(x)=3x-7 and g(x)=2x². Perform the function operation and then find the domain of the reult
Answers
The Correct option is A, the domain of the result is the domain of f-g is the set of all real numbers .
We have,
f(x) = 3x - 7
g(x) = 2x²
Solve (f-g)(x), we get
(f-g)(x) = 3x - 7 - (2x²)
(f-g)(x) = 3x - 7 - 2x²
(f-g)(x) = - 2x² + 3x - 7
Real numbers are a type of mathematical numbers that can be either positive, negative, or zero, and can be expressed as a decimal or fraction. Real numbers are used to describe continuous quantities, such as length, weight, and time. Real numbers are also used in algebra, calculus, and geometry. The set of real numbers is denoted by using the symbol R. The real numbers include rational numbers (numbers that can be expressed as a fraction), and irrational numbers (numbers that cannot be expressed as a fraction).
Real numbers are also used in various mathematical models and equations to make predictions and solve problems. Examples of real numbers include pi, e, and the square root of 2. The real numbers can also be visualized on the number line, where each real number is assigned a unique point. In conclusion, real numbers are a fundamental part of mathematics and play a crucial role in various fields.

How many fluid ounces in a tablespoon
Answers
By rewriting a relation we will see that there are 0.5 fluid ounces in a tablespoon.
How many fluid ounces are in a tablespoon?We know the relation between the different units:
1 fluid ounce = 2 tablespoons.
To see how many fluid ounces are in a tablespoon, we just need to work with the relation above and write "1 tablespoon" on the right side.
So if we take our relation:
1 fluid ounce = 2 tablespoons.
And we divide both sides by 2 then we will get:
1/2 fluid ounce = 2/2 tablespoons.
0.5 fluid ounces = 1 tablespoon.
then we can conclude that there is 0.5 fluid ounces in a tablespoon.

Answer:
x = 73
Step-by-step explanation:
The measure of the sum of the arcs in a circle = 360°.
Sum the given arc measures and equate to 360, that is
95 + 52 + 67 + 2x = 360
214 + 2x = 360 ( subtract 214 from both sides )
2x = 146 ( divide both sides by 2 )
x = 73
