Answer:

-5

Step-by-step explanation:

The rate of change, also known as slope, would be -5.

Slope can be found with two points and the formula y minus y divided by x minus x or the change of y divided by the change in x.

To identify the slope on the equation is easy since this is slope-intercept form.

y=mx+b

where m is the slope

m in this case is -5, so -5 is your answer

The value of p pennies, n nickels and twice as many quarters as pennies is (51p + 5n) cents or  $(51p + 5n)/100.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. Expressions have the following structure: (Number/variable, Math Operator, Number/variable).

Given that you have p number of coins of pennies, n number of coins of nickels and  twice as many quarters as pennies.

Thus the number of coins of quarters is 2p.

The value of penny, nickel, and quarter are

1 penny = 1 cent

1 nickel = 5 cents

1 quarter = 25 cents

The value of p number of pennies is p cents.

The value of n number of nickels is (n×5) =5n cents.

The value of 2p number of quarter is (2p × 25) = 50p cent.

The total value is p + 5n + 50p = (51p + 5n) cents

Divide 51p + 5n by 100 to convert it into dollar:

(51p + 5n) cents = $(51p + 5n)/100

Answer: The expression a²+4b² can be factored in the following way:

a²+4b² = (a² + 2ab + 2ab + 4b²)

= (a+b)²

In general, the square of a binomial (a+b) can be written as (a+b)² = a² + 2ab + b². This is known as the "square of a sum" formula. In this case, we can apply this formula to the binomial a+b to obtain a² + 2ab + b² = (a+b)². We can then use the fact that the square of a binomial can be written as the square of each term plus twice the product of the two terms. This allows us to write the expression as (a+b)² = a² + 2ab + b² = a² + 2ab + 2ab + 4b² = (a² + 2ab + 2ab + 4b²) = (a²+4b²). Therefore, the fully factored form of a²+4b² is (a+b)².

The area under the graph using the first two and then four rectangles = 0.221 unit square

According to the graphs given in the below figure,

Given in the question,

f(x) = [tex]x^{3}[/tex] when x = 0 and x = 1

The first rectangle of the first graph goes from 0 to 0 .6,

Width = 0.6

Height measured from the middle point = 0.3

f( 0.3) = [tex]( 0.3)^{3}[/tex]

f(0.3) = 0.027 units.

Area of first rectangle = 0.6 x 0.027 = 0.0162 unit square

Now taking the second rectangle of the first part,

It is going from 0.6 to 1.0,

Width = 0.4 units

height = 0.8 units

Height measured from the middle-

f(0.8) = [tex](0.8)^{3}[/tex] = 0.512

Area of the second part of the rectangle = 0.512 x 0.4

= 0.2048 unit square

Final area = 0.2048 + 0.0162 = 0.221 square units

Therefore, the same could be done with the second part rectangle of 4

For the given first part of four rectangles = width = 0.6 units and height = 0.1 unit

so f(0.1) = [tex]0.1^{3}[/tex]

= 0.001 units

1.6 seconds. The ball will hit the canopy after 1.58 seconds or -1.58 seconds. Since the time cannot be negative, the ball will hit the canopy after 1.58 seconds.

To find the time it takes for the ball to hit the canopy, we need to solve the equation h(t) = 12 for t.

The given equation for h(t) is h(t) = -16t^2 + 52, so we can substitute this into the equation h(t) = 12 to get:

12 = -16t^2 + 52

To solve this equation, we can move all the terms to one side of the equation to get:

-16t^2 + 40 = 0

We can then divide both sides of the equation by -16 to get:

t^2 - 2.5 = 0

We can then use the quadratic formula to solve for t:

t = +/- sqrt(2.5)

t = +/- 1.58

Thus, the ball will hit the canopy after 1.58 seconds or -1.58 seconds. Since the time cannot be negative, the ball will hit the canopy after 1.58 seconds.

Rounding this answer to the nearest tenth gives us 1.6 seconds, so the correct answer is 1.6 seconds.

Stem and leaf plots were also confusing to me at first, but once you understand they are actually easy!

Look at the first column where it says 2,3,4,5 and 6. Those are the tens place. The columns next to it with 2,3,8,9,etc are the ones place. For example, the first column has two, so we know that the number has a two in the tens place.

2_

Look at the numbers next to it, there's 2,3, and 8.

Since there's 3 numbers, that means that there are three numbers that have a two in the ones place. 2,3 and 8 are the numbers that go in the ones place.

So in the graph there is 22,23 and 28.

If you look at your choices, you can find all of them except 38, since on the row with the 3, next to it is the number 9 and not the number 8.

The probability that a resident own a cat or a dog is 48%

From the question, we have the following parameters that can be used in our computation:

P(Own a cat) = 70%

P(Own a dog) = 59%

P(Own a cat and a dog) = 42%

The probability a resident own a cat or a dog is then calculated as

Probability a resident own a cat or a dog = P(Own a cat) + P(Own a dog) - P(Own a cat and a dog)  

Substitute the known values in the above equation, so, we have the following representation

Probability a resident own a cat or a dog = 70% + 59% - 42%

Evaluate the sum and the difference

Probability a resident own a cat or a dog = 48%

The probability that the sample's Republican percentage will be higher than 44% is 0.089.

Probability is a metric used to express the possibility or chance that a particular event will occur.

Probabilities can be expressed as fractions from 0 to 1, as well as percentages from 0% to 100%.

To determine the probability of a sample proportion, the normal probability is used as the z-test statistic of one sample proportion.

When the sample size is big, the z-test statistic, a normal test statistic, is employed.

So, the probability will be:

We know that the sample size is n = 488 and the proportion is p = 0.41.

Now, obtain P(p > 0.44) as follows:

[tex]\begin{aligned}& P(\hat{p} > 0.44)=1-P\left(\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}} \leq \frac{0.44-p}{\sqrt{\frac{p(1-p)}{n}}}\right) \\& P(\hat{p} > 0.44)=1-P\left(Z \leq \frac{0.44-0.41}{\sqrt{\frac{0.41(1-0.41)}{488}}}\right) \\& P(\hat{p} > 0.44)=1-P(Z \leq 1.347)\end{aligned}[/tex]

Excel function for the p-value:

P(p > 0.44) = 1 - 0.911

P(p > 0.44) = 0.089

Therefore, the probability that the sample's Republican percentage will be higher than 44% is 0.089.

When the costs of the two plans are equal, plan A will cost $37.81, whereas plan B will cost $25.65.

To find the number of calls at which the two plans cost the same, we need to set the costs equal to each other and solve for the number of minutes. The cost of plan A is $19 + $0.11 per minute, and the cost of plan B is $0.15 per minute. Setting these equal to each other, we get:

$19 + $0.11 per minute = $0.15 per minute

We can then solve for the number of minutes by dividing both sides by the per-minute cost:

$19 / $0.11 per minute = $0.15 per minute / $0.11 per minute

This simplifies to:

171 minutes = 135 minutes

Therefore, the two plans cost the same at 171 minutes of calling.

To find the cost at this point, we can substitute 171 minutes back into either of the original cost equations:

Plan A: $19 + $0.11 per minute × 171 minutes = $19 + $18.81 = $37.81

Plan B: $0.15 per minute × 171 minutes = $25.65

Thus, the cost when the two plans cost the same is $37.81 for plan A and $25.65 for plan B.
