Answer:

the answer is C

Step-by-step explanation:

Area = length x width.

Divide the two total areas by the width to find the lengths:

760/16 = 47.5

1000/16 = 62.5

The interval is:

47.5<= x <= 6.5

The interval for the length of x that you will cover before you need to buy more roof coating will be 47.5 ≤ x ≤ 6.5.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.The space occupied by any two-dimensional figure in a plane is called the area.

Given that you have 20 gallons of roof coating to apply to the roof of a mobile home that is 16 feet wide. Twenty gallons covers 760 to 1000 square feet.

The formula to calculate the area of the

Area = length x width.

Divide the two total areas by the width to find the lengths:

760/16 = 47.5

1000/16 = 62.5

The interval is:

47.5 ≤ x ≤ 6.5

Therefore, the interval will be 47.5 ≤ x ≤ 6.5.

Answer: The values are opposites of each other, and they are both three and one fourth units from zero.

Step-by-step explanation: -3\(\frac{1}{4}\) and 3\(\frac{1}{4}\) are opposites because they have opposite signs. They are both three and one fourth units if you count from them to zero.

The correct answer is: The values are opposites of each other, and they are both three and one fourth units from zero.

In the given number line, negative three and one fourth (-3 1/4) and positive three and one fourth (3 1/4) are labeled.

The values -3 1/4 and 3 1/4 are opposites of each other because one is negative and the other is positive.

The negative sign indicates a value to the left of zero, while the positive sign indicates a value to the right of zero.

This makes them opposites in terms of direction.

Additionally, both values are three and one fourth units away from zero.

The distance from zero is determined by the absolute value of the number, which ignores the sign.

Therefore, regardless of the positive or negative sign, the distance from zero for both -3 1/4 and 3 1/4 is three and one fourth units.

So, the two plotted values are opposites of each other and have the same distance from zero, which is three and one fourth units.

Answer: 24 Dollars and 94 Cents

Step-by-step explanation: 4% of 20 = .8

4% of 20.8= .832

4% of 21.6 = .864

4% of 22.4 = .896

Take the 32,64 and the 96. Add them 32+64+96= 192 so 1.92

22.4 + .8 = 23.2

23.2+ 1.92 = 24. 94 cents

24 Dollars and 94 Cents is your answer (or whichever of you answers is closest)

Answer: (B)      f(x) = x + 2

Step-by-step explanation: Let's start by finding the "y-intercept".

1.  First you can see that the table is not set to the y-intercept automatically, so we have to infer on our own. In the table, you can see that the change from each number is the same. So the y-intercept would be +2 as x = 0, y = 2

2. Looking back at the changes between each box, x for the first change = +4, then for the second = +2, then for the third = +2. Then y for the first = -4, then for the second = -2, then for the third = -2.

So from all of that if you put that into slope form then it would look like 4/-4 = -1x

3. You might be asking why there is a -1x not x since x is the answer. Truth is I really don't know but again the one that makes the most sense is option B.  f(x) = x + 2

Answer:

8 possible outcomes

Step-by-step explanation:

When flipping a quarter three times, each flip can result in two possible outcomes: either landing heads (H) or tails (T).

Since each flip is independent, the total number of possible outcomes for flipping a quarter three times can be found by multiplying the number of outcomes for each flip together.

For three flips, the total number of possible outcomes is:

2 x 2 x 2 = 8

So, there are 8 possible outcomes when Alexandre flips a quarter three times.

This dilation is an expansion, so in order for it to expand, the center of dilation need to be in the middle or near the middle of the pre-image.

What is a pre-image?

Noun. preimage (plural preimages) (mathematics) For a given function, the set of all elements of the domain that are mapped into a given subset of the codomain; (formally) given a function ƒ : X → Y and a subset B ⊆ Y, the set ƒ−1(B) = {x ∈ X : ƒ(x) ∈ B}.

What is an Image?

The new position of a point, a line, a line segment, or a figure after a transformation is called its image.

Center of Dilation:

The center of a dilation is a fixed point in the plane about which all points are expanded or contracted. The center is the only invariant (not changing) point under a dilation (k ≠1), and may be located inside, outside, or on a figure.

The second urn contains 16 green balls and 46 blue balls.

Let's first find the probability of drawing two green balls, which we'll denote as P(G,G).

We can break it down into two cases:

Case 1: A green ball is drawn from the first urn and a green ball is drawn from the second urn.

The probability of drawing a green ball from the first urn is 4/10, and the probability of drawing a green ball from the second urn is 16/(16+N). Therefore, the probability of this case is (4/10) x (16/(16+N)).

Case 2: A blue ball is drawn from the first urn and a blue ball is drawn from the second urn.

The probability of drawing a blue ball from the first urn is 6/10, and the probability of drawing a blue ball from the second urn is N/(16+N). Therefore, the probability of this case is

(6/10) x (N/(16+N))

The probability of drawing two balls of the same color is the sum of the probabilities of these two cases, which we know to be 0.58:

P(G,G) + P(B,B) = 0.58

We can solve for P(G,G) as follows:

P(G,G) = 0.58 - P(B,B)

= 0.58 - (6/10) x (N/(16+N))

Now, we can set P(G,G) equal to the probability of drawing two green balls from the urns that we found earlier:

(4/10) x (16/(16+N)) = 0.58 - (6/10) x (N/(16+N))

By simplifying this equation, we get:

64 = 58(16+N) - 60N

By solving for N, we get:

N = 46

The correct answer to this statistical problem is (c) uncertain, because there are other variables at play and correlation does not equal causation.

In this scenario, we're looking at the sales of Ben and Jerry's ice cream before and after the advertisement was introduced. The sales increased by 30% for the following three months after the advertisement. So, does this mean that the advertisement was effective? The answer is not as straightforward as a simple "yes" or "no."

Option (c) acknowledges that there are other variables at play and that correlation does not equal causation.

This is the most accurate answer because it recognizes that while the increase in sales may be related to the advertisement, it's impossible to say for sure whether the advertisement was the cause of the increase in sales.

There could be other factors, such as the weather or a change in consumer preferences, that also contributed to the increase in sales.

Answer:

You cant use acre to describe distance walked

Step-by-step explanation: Because 1 acre is 43560ft

Answer:

See explanations below

Step-by-step explanation:

In the function

f(x) = x + 30

x represents the volume of coal in cubic yards.

The implicit coefficient of one, i.e. 1x, represents each cubic yard of coal weighs one ton.

The 30 represents the weight in tons of the empty coal car.

Thus when the weight of the coal car is only 26 tons, we replace 30 by 26 to get a new function

f(x) = x + 26.

a) The mean of the sample is (4+8+0+10+3)/5 = 5. The sample standard deviation is calculated as follows:

s = sqrt([(4-5)^2 + (8-5)^2 + (0-5)^2 + (10-5)^2 + (3-5)^2]/(5-1))

= sqrt([1+9+25+25+4]/4)

= sqrt(64/4)

= 2√2

≈ 2.83

Therefore, the mean of the sample is 5 and the standard deviation is approximately 2.83.

b) To find the Z-score for each score in the sample, we use the formula:

Z = (X - μ) / σ

where X is the score, μ is the mean of the sample, and σ is the standard deviation of the sample.

The Z-scores for the sample are:

Z(4) = (4-5) / 2.83 ≈ -0.35

Z(8) = (8-5) / 2.83 ≈ 1.06

Z(0) = (0-5) / 2.83 ≈ -1.77

Z(10) = (10-5) / 2.83 ≈ 1.77

Z(3) = (3-5) / 2.83 ≈ -0.71

c) To transform the original sample into a new sample with a mean of M = 100 and s = 20, we use the following formula:

X' = Z( X) × s + M

where X' is the transformed score, Z(X) is the Z-score for the original score X, s is the desired standard deviation, and M is the desired mean.

The transformed scores for the sample are:

X'(4) = -0.35 × 20 + 100 ≈ 92.98

X'(8) = 1.06 × 20 + 100 ≈ 121.27

X'(0) = -1.77 × 20 + 100 ≈ 63.46

X'(10) = 1.77 × 20 + 100 ≈ 136.54

X'(3) = -0.71 × 20 + 100 ≈ 85.83

d) The stacked distribution shows the original sample (in blue), the Z-scores (in green), and the transformed sample (in red).

We notice that the relative position of individual scores within each distribution is the same. For example, the score of 8 is the highest score in the original sample, and it also has the highest Z-score and the highest transformed score.

Similarly, the score of 0 is the lowest score in the original sample, and it also has the lowest Z-score and the lowest transformed score. The relative ordering of the scores is preserved across all three distributions.
