Step-by-step explanation:

For the first three, there's an open circle so the sign for the inequality would be < or > but for the last two, there's a closed circle so the sign for the inequality would be <= or >=, the ones with a line underneath. For 1, 3, and 4, the line goes to the left, showing that x is a number less than the point so it would have <, the less than sign. For 2 and 5, the line goes to the right, showing that x is a number greater than the point so it would have >, the greater than sign.

There's a trick to figuring out the right sign. If the line is pointing to the left, the inequality would be x < __, and the sign is pointng to the left. If the line is pointing to the right, the inequality would be x > __, and the sign is pointng to the right. This only works is x is on the left side of the inequality.

Answer:

A and C

Step-by-step explanation:

Let Triangle ABC is a right angle traingle.

From Option A

AB= 24, BC= 26 and AC=10

By Pythagorean Triplet

(AB)^2 + (AC)^2 = (24)^2 + (10)^2

= 576+100

(AB)^2 + (AC)^2 = 676 ---------------- (I)

(BC)^2 = 26^2 = 676 -------------------(ii)

From (I) and (ii)

(BC)^2 = (AB)^2 + (AC)^2

Therefore, the sides 10,24 and 26 are the sides of the right angle triangle.

From Option C

AB= 18, BC= 30 and AC=24

By Pythagorean Triplet

(AB)^2 + (AC)^2 = (18)^2 + (24)^2

= 324+576

(AB)^2 + (AC)^2 = 900---------------- (I)

(BC)^2 = 30^2 = 900 -------------------(ii)

From (I) and (ii)

(BC)^2 = (AB)^2 + (AC)^2

Therefore, the sides 18, 24 and 30 are the sides of the right angle triangle.

Answer:

40 inches

Step-by-step explanation:

We know that the height of water in a pool decreased 5 inches per week.

This means that we can form the equation \(y=-5x\), since the amount of water remaining is proportionate to the amount of weeks that have passed.

We know \(x=8\), since we need to find the change for 8 weeks.

\(y = -5\cdot 8\)

\(-5 \cdot 8 = -40\)

\(y=-40\)

The change will be the absolute value of -40, which just makes it positive, so 40.

Answer:

24t+30

Step-by-step explanation:

We will split this into two different equations 2(2t+3) and 6(4t-4)

To expand the first part we must multiple each number in the parentheses by the outside number which is 2* 2t= 4t and 2*3= 6

We must do the same process for the second part which has a negative comes to be 6*4t = -24t and 6*-4= -24

Now that we have it fully expanded we must now add like terms:

4t - (-24t) =24t

6-(-24) = 30

Combined the new equation is 24t+30

For a pack of 52 cards, two cards are drawn together, the probability that one card is clubs and one card is spades is equals to the

\(= \frac{13}{102}\)

Probability is chances of occurrence of an event. It is calculated by dividing the favourable response to the total possible outcomes. We have a pack of 52 cards. Let's consider an event E : card is one card is culb and one is spade

Total possible outcomes = 52

Two cards are drawn together from a pack. So, number of total possible outcomes for drawing two cards from a pack, n(T) = ⁵²C₂ = 1326

In a 52 cards pack, number of spades = 13

Number of clubs cards in pack = 13

Number of ways of choosing/drawing one spades card out of 13 and one one clubs out of 13 cards, n(E) = 169

Probability that one card is clubs and one card is spades on drawing two cards,

\( P(E) = \frac{ n(E)}{n(T)}\)

\(= \frac{169}{1326}\)

\(= \frac{13}{102}\)

Hence, required probability value is \(= \frac{13}{102}\).

The IQR for the average of 35 coffee drinkers is approximately 1.4828 ounces.

To find the IQR (interquartile range) for the average of 35 coffee drinkers, we need to first find the standard error of the mean, which is the standard deviation divided by the square root of the sample size:

Standard error of the mean = 6.5 / sqrt(35) = 1.0967

Next, we can use the formula for the IQR:

IQR = Q3 - Q1

To find Q1 and Q3, we need to use the normal distribution table or a calculator that can perform normal distribution calculations. Using a standard normal distribution table, we can find the z-scores corresponding to the 25th and 75th percentiles, which are -0.6745 and 0.6745, respectively.

We can then use the formula:

Q1 = mean - z-score * standard error of the mean
Q3 = mean + z-score * standard error of the mean

Q1 = 17 - (-0.6745) * 1.0967 = 17.7499
Q3 = 17 + 0.6745 * 1.0967 = 17.9501

Therefore, the IQR for the average of 35 coffee drinkers is:

IQR = 17.9501 - 17.7499 = 0.2002 ounces (rounded to 4 decimal places).

Based on the information provided, we have a normal distribution with a mean of 17 ounces and a standard deviation of 6.5 ounces for daily coffee consumption. Since 35 people were surveyed, we can calculate the IQR (Interquartile Range) for the average of these 35 coffee drinkers.

First, we need to find the standard error (SE) of the sample mean, which is the standard deviation divided by the square root of the sample size:

SE = σ / √n = 6.5 / √35 ≈ 1.0987

Now, we need to find the z-scores corresponding to the first quartile (Q1) and the third quartile (Q3). For a normal distribution, Q1 corresponds to the 25th percentile (0.25) and Q3 corresponds to the 75th percentile (0.75). Using a z-table or calculator, we find:

z(Q1) ≈ -0.6745
z(Q3) ≈ 0.6745

Next, we find the corresponding ounce values for Q1 and Q3 by using the z-scores, the mean, and the standard error:

Q1 = μ + z(Q1) * SE ≈ 17 + (-0.6745) * 1.0987 ≈ 16.2586 ounces
Q3 = μ + z(Q3) * SE ≈ 17 + 0.6745 * 1.0987 ≈ 17.7414 ounces

Finally, we calculate the IQR by subtracting Q1 from Q3:

IQR = Q3 - Q1 ≈ 17.7414 - 16.2586 ≈ 1.4828 ounces

Answer:

\(y=-2x+12\)

Step-by-step explanation:

We can use the point-slope form given by:

\(y-y_1=m(x-x_1)\)

Where m is the slope and (x₁, y₁) is a point.

So, we will substitute -2 for m and (5, 2) for (x₁, y₁). This gives us:

\(y-(2)=-2(x-(5))\)

Simplify:

\(y-2=-2(x-5)\)

Distribute:

\(y-2=-2x+10\)

Add 2 to both sides. Hence, our equation is:

\(y=-2x+12\)

Slope AB = slope CD = 1/1 and slope BC ≠ slope DA. Therefore, AB and CD are parallel sides, and ABCD is a trapezoid.

In geometry, a trapezoid (also known as a trapezium in some countries) is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs.

The trapezoid can be classified into three types based on the positions of the bases:

Isosceles trapezoid: A trapezoid in which the non-parallel sides are congruent.

Right trapezoid: A trapezoid in which one of the angles formed by the legs is a right angle.

Scalene trapezoid: A trapezoid in which none of the sides are congruent.

The area of a trapezoid can be calculated by the formula:

A = (b1 + b2)h/2

where b1 and b2 are the lengths of the bases and h is the height of the trapezoid (the perpendicular distance between the bases).

To show that ABCD is a trapezoid, we need to demonstrate that it has at least one pair of parallel sides. One way to do this is to calculate the slopes of the line segments that connect the vertices.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Using this formula, we can calculate the slopes of the four line segments:

slope AB = (4 - 1) / (2 - (-1)) = 3/3 = 1

slope BC = (1 - 4) / (3 - 2) = -3/1 = -3

slope CD = (-3 - 1) / (-3 - 3) = -4/-6 = 2/3

slope DA = (1 - (-3)) / (-1 - (-3)) = 4/2 = 2

We can see that slope AB = slope CD = 1/1 and slope BC ≠ slope DA. Therefore, AB and CD are parallel sides, and ABCD is a trapezoid.

In all cases, the p-value is less than the significance level of 0.05, so we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis. The probability of observing a sample proportion as extreme or more extreme than the one observed, assuming the null hypothesis is true, is very low.

To compute the p-value, we first need to calculate the test statistic z-score using the sample proportion and the null hypothesis.

a. x = 51; n = 100

The sample proportion is p-hat = x/n = 51/100 = 0.51

The test statistic is z = (p-hat - p0) / sqrt(p0(1-p0)/n) = (0.51 - 0.59) / sqrt(0.59(1-0.59)/100) = -2.41

Using a standard normal distribution table, we find that the p-value is 0.0081.

b. x = 138; n = 276

The sample proportion is p-hat = x/n = 138/276 = 0.50

The test statistic is z = (p-hat - p0) / sqrt(p0(1-p0)/n) = (0.50 - 0.59) / sqrt(0.59(1-0.59)/276) = -3.27

Using a standard normal distribution table, we find that the p-value is 0.0005.c. p¯p¯ = 0.54; n = 53

The test statistic is z = (p-hat - p0) / sqrt(p0(1-p0)/n) = (0.54 - 0.59) / sqrt(0.59(1-0.59)/53) = -1.62

Using a standard normal distribution table, we find that the p-value is 0.0526.d. p¯p¯ = 0.54; n = 425

The test statistic is z = (p-hat - p0) / sqrt(p0(1-p0)/n) = (0.54 - 0.59) / sqrt(0.59(1-0.59)/425) = -4.42

The volume formed by rotating the region enclosed by `y = 4x` and `y = 16` about the line `y = 16` is `2048π/3`.

To find the volume formed by rotating the region enclosed by `y = 4x` and `y = 16` about the line `y = 16`, we need to apply the Washer Method. Here, we consider the area of the disk perpendicular to the axis of rotation and sum them up in order to find the total volume. We can find the area of the disk with the following formula:`A = π(R² − r²)`Where R and r represent the radii of the outer and inner circles, respectively. In this case, the line `y = 16` is the axis of rotation and the function `y = 4x` is the outer curve. The inner curve is simply the axis of rotation itself, i.e., `y = 16`.To solve this problem, we first need to find the points of intersection of the two curves.`4x = 16``x = 4`Therefore, the region enclosed by `y = 4x` and `y = 16` is bounded by the lines `x = 0`, `x = 4`, `y = 4x` and `y = 16`.

To apply the Washer Method, we need to integrate with respect to x. The volume of the region is given by:`V = ∫(π(R² − r²))dx``V = ∫(π(16² − 4x² − 16²))dx``V = ∫(π(256 − 4x²))dx``V = π∫(256 − 4x²)dx``V = π[256x − 4(x³/3)]₀^4``V = π(256(4) − 4(4³/3))``V = 2048π/3`Therefore, the volume formed by rotating the region enclosed by `y = 4x` and `y = 16` about the line `y = 16` is `2048π/3`.
