The Probability of Landing a heads is (1/2)

Now, to find the probability of landing it five times in a row, it is

1/2 x 1/2 x 1/2 x 1/2 x 1/2

( 1/2 is multiplied to the number of times to get a head )

The final answer will be,

Probability of landing heads 5 times in a row = 1/32

Let us start by looking at the difference between statistical and non statistical question.

For a statistical question. a single answer is usually impossible while a statistical question has a single answer.

If someone asks how old are you, the answer is simple and it is expected to be a single answer.

If the question is how old are the boys in your neighborhood, a single answer is not possible. The ages are different since some are older than the others. In this case, there is spread in the data. We would be considering looking for the average age of a given number of boys. We may also consider the spread of the ages and other parameters like range, median etc

Answer:

3/5

Step-by-step explanation:

2/5 + 1/5

The denominator is the same, so we add the numerators

3/5

Answer:

3/5

Step-by-step explanation:

We need to add the two fractions 2/5 and 1/5.

First, see if we need to find their common denominator: they both have a denominator of 5, so we're all set there!

Now, just add the numerators together:

2/5 + 1/5 = (2 + 1)/5 = 3/5

The denominator will stay 5 (don't add the 5's together).

The final answer is thus 3/5.

Step-by-step explanation:

The function h(x) = 1-x has a removable discontinuity at a=4 because the function is not defined at that point.

The conditional function h(x) = 1-x has a discontinuity at a=4. This type of discontinuity is called a removable discontinuity or a point discontinuity.

To understand why this is the case, let's analyze the function h(x) = 1-x when x is less than 4 and when x is greater than 4.

When x is less than 4, the expression 1-x is defined and has a value. For example, if x=3, then h(3) = 1-3 = -2. So, the function is defined and continuous on the left side of x=4.

When x is greater than 4, the expression 1-x is also defined and has a value. For example, if x=5, then h(5) = 1-5 = -4. So, the function is defined and continuous on the right side of x=4.

However, when x=4, the expression 1-x is not defined because it leads to division by zero. Therefore, there is a discontinuity at x=4, where the function is not defined.

This type of discontinuity is called a removable discontinuity because it can be "removed" by assigning a value to the function at x=4. For example, if we redefine h(4) as 0, then the function becomes continuous at x=4.

In conclusion, the function h(x) = 1-x has a removable discontinuity at a=4 because the function is not defined at that point.

• Ratio: 2

• Lengths of the sides of the new triangle: 6, 6√2

• Circles: ,see explanation

• Triangle: ,see explanation

EXPLANATION

• The ratio is the quotient between the length of segment DE and, for example, segment AB,

• Now, we have to multiply each side of triangle ABC by 2 to obtain the lengths of the sides of triangle DEF,

• Next, draw the two circles mentioned,

• The intersection between the two circles is point F. The ,triangle is,

1) a = 0.60 , The MAD for this forecast is 4.5 surgeries.

2)a = 0.90, The MAD for this forecast is 3.46 surgeries.

3)Using a 3-year moving average, The MAD for this forecast is 7.0 surgeries.

4)The trend-projection method provides forecasts for years 1 through 6: 46.6, 49.8, 53.0, 56.2, 59.4, and 62.6 surgeries, respectively. The MAD for the trend-projection method is not provided.

Exponential smoothing is a forecasting method that assigns exponentially decreasing weights to historical data, with the most recent data given the highest weight. By adjusting the smoothing factor (a), we can control the responsiveness of the forecast to recent changes. A higher value of a gives more weight to recent data.

In the given scenario, when using exponential smoothing with a = 0.60, the forecast for year 1 (44.0 surgeries) is taken as the initial forecast. The subsequent forecasts are calculated by adding a proportion of the difference between the actual observation and the previous forecast.

This results in the forecasted values of 46.4, 47.4, 50.8, 53.9, and 57.6 surgeries for years 2 through 6, respectively.

Similarly, when using exponential smoothing with a = 0.90, the forecast for year 1 remains the same (44.0 surgeries). The subsequent forecasts are adjusted based on a higher weight given to recent observations.

This leads to the forecasted values of 47.6, 48.0, 52.5, 55.6, and 59.6 surgeries for years 2 through 6, respectively.

On the other hand, the 3-year moving average forecast considers the average of the past three observations to make future predictions. For years 4 through 6, the moving average forecasts are 49.7, 52.3, and 56.3 surgeries, respectively.

Finally, the trend-projection method incorporates both the historical data and the trend observed in the data. It assumes that there is a linear relationship between the time period and the number of surgeries.

By fitting a trend line to the data, the method predicts future values. In this case, the trend-projection method yields the forecasts of 46.6, 49.8, 53.0, 56.2, 59.4, and 62.6 surgeries for years 1 through 6, respectively. The MAD for this method cannot be calculated based on the given information.

The null hypothesis is that the proportion of people who would still vote for the government of Preon is still 67%, while the alternative hypothesis is that the proportion has changed from 67%.

The null hypothesis (H0) is that the proportion of people who would still vote for the government of Preon is still 67%, as it was at the last election.

The alternative hypothesis (H1) is that the proportion of people who would still vote for the government of Preon has changed from 67%, either increased or decreased.

In symbols, this can be written as:

H0: p = 0.67

H1: p ≠ 0.67

Where p is the proportion of people who would vote for the government of Preon in the upcoming election.

Note that the alternative hypothesis is two-tailed, indicating that the proportion could have either increased or decreased from 67%.

This is because the government suspects that their approval rating may have changed in either direction.

Answer:  y = ¹/₂x + 2

Step-by-step explanation: This is slope-intercept form. y = mx + b

m is the slope. Rise/run

The difference in y-values is the rise. The difference in x-values is the run.

Look for places where the graphed line intersects the grid. Count the squares. Here, the graphed line rises 1 square as it runs 2 squares.

b is the y-intercept. Here, that is 2

The interval of convergence, i, of the given series is (-∞, ∞).

The given series is

[infinity] xn 4 / 4n! n = 0.

Lets find the radius of convergence, r:

The general term of the given series is xn 4 / 4n!.

So, the ratio of two consecutive terms is given by;

|xn+1 4 / 4(n + 1)!| / |xn 4 / 4n!| = |xn+1| / |xn| * 1 / (n + 1) * 4 / 4 = |xn+1| / |xn| * 1 / (n + 1)

To find the radius of convergence, we take the limit of the above expression as n approaches infinity:

limn→∞ |xn+1| / |xn| * 1 / (n + 1) = LHere, L = limn→∞ |xn+1| / |xn| * 1 / (n + 1)

Because xn+1 and xn are two consecutive terms of the series;

0 ≤ L = limn→∞ |xn+1| / |xn| * 1 / (n + 1)≤ limn→∞ 4 / (n + 1) = 0

The above inequality implies L = 0.

Hence, the radius of convergence, r, is given by:r = 1 / L = ∞

The radius of convergence of the given series is ∞.

The given series is [infinity] xn 4 / 4n! n = 0.

We know that the radius of convergence of the series is ∞.

The interval of convergence, i, is given by;[-r, r] = [-∞, ∞]

Answer:

Nelson's average speed was 8 miles per hour.

Step-by-step explanation:

To find Nelson's average speed, you need to divide the distance he traveled by the time it took him to travel that distance. In this case, Nelson traveled 20 miles in 2 1/2 hours, so his average speed was 20 miles / 2.5 hours = <<20/2.5=8>>8 miles per hour.

Answer:

8 miles per hour

Step-by-step explanation:

In order to find Nelson's average speed, we can set up a proportion. To solve for x, x being miles traveled in one hour.

\(\frac{20 miles}{2.5hours} =\frac{x miles }{1 hour}\)

x= 8

Answer: 10 wreaths

Step-by-step explanation:

First identify the terms.

She has a booth that cost $200. This price will not change thus making it a Fixed cost.

Making a wreath would cost her $10 each time so this is a Variable cost.

She sells the wreath for $30 so this is the selling price.

Breakeven = Fixed Cost / Contribution margin

Contribution margin = Selling price - Variable cost

= 30 - 10

= $20

Breakeven point = 200/20

= 10 wreaths

The number is 28 bleacher seats, and 1 lower reserved seat were bought.

To solve this problem, we need to use a system of equations. Let x be the number of bleacher seats and y be the number of lower reserved seats. Then we have two equations:
x + y = 29  (since there were a total of 29 seats bought)
10x + 25y = 913  (since the total cost was $913)

To solve for x and y, we can use substitution or elimination. Let's use substitution. Solve the first equation for x:
x = 29 - y

Now substitute this expression for x in the second equation:
10(29 - y) + 25y = 913

Expand and simplify:
290 - 10y + 25y = 913
15y = 623
y = 41.5

Since we can't have half a seat, we know that y must be a whole number. But we made an assumption that x and y were both integers, so we need to go back and check if that assumption was correct.

If y = 41, then x = 29 - y = 29 - 41 = -12. That doesn't make sense, so we know that y must be 42.

Now we can solve for x:
x = 29 - y = 29 - 42 = -13

Again, that doesn't make sense, so we made another assumption that x and y were both positive.
If y = 1, then x = 29 - y = 29 - 1 = 28.

Whats the question?

Step-by-step explanation:

Mark the sides BC and DF as congruent.

A triangle in geometry is a three-sided polygon with three edges and three vertices.

The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.

This characteristic is known as the triangle's angle sum property.

If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.

In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.

A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.

The vertex is the intersection of two straight lines. The triangle therefore has three vertices.

According to our question-

We are given a side and an adjacent angle, and we must figure out which side or angle is needed in order for SAS to provide proof.

The probability that the student makes it to the second class before it starts is very close to 0.

To find the probability that the student makes it to the second class before it starts, we can use the concept of linear combinations of random variables and the properties of normal distributions.

Let's define the random variable X as the total time it takes for the student to transition from the end of the first class to the start of the second class. Since X is a linear combination of independent normally distributed random variables (X1, X2, X3), we can use their means and variances to calculate the mean and variance of X.

The mean of X is the sum of the means of X1, X2, and X3:

μX = μ1 + μ2 + μ3 = 9:02 + 9:15 + 10 = 28:17 minutes.

The variance of X is the sum of the variances of X1, X2, and X3:

σX^2 = σ1^2 + σ2^2 + σ3^2 = (2.5)^2 + (3)^2 + (2.5)^2 = 15.25 minutes^2.

Now, we need to calculate the probability that X is less than or equal to 0, meaning the student arrives before the second lecture starts. Since X follows a normal distribution, we can standardize the variable and calculate the probability using the standard normal distribution table.

Z = (0 - μX) / σX = (0 - 28:17) / √15.25 ≈ -9.43.

Using the standard normal distribution table or a calculator, we can find the probability corresponding to Z = -9.43. The probability is essentially 0, as the value is significantly far in the left tail of the standard normal distribution.

Therefore, the probability that the student makes it to the second class before it starts is very close to 0.
