What is the question I don’t understand

The points are ( -4,6) , (-2,0) and (0,-6).

As we can see that as x value increases by 2 points , the y value correspondingly decreases by 6 points , constantly.

It means the date is linear.

So we can model the data using a linear model , or linear equation.

In the form y=mx+b

where , m is the slope of line and b is the y intercept .

y intercept is already given by the point (0,-6)

It means b=-6

to find the slope we use the formula

m=\frac{(y_2 -y_1)}{(x_2-x_1)}= \frac{(-6-0)}{(0-(-2))} = \frac{-6}{2} = -3

So m=-3

So we get the equation as

y=-3x-6

But she is using letter v

So the equation should be

v= -3x-6

A rectangle has side lengths of (2x+3) and (3x - 4).
Sergeu [11.5K]

Answer:

Area=6x^2+9x-12       Perimeter= 5x-1

Step-by-step explanation:

when finding the are of a rectangle you multiply both sides together.

(2x+3)*(3x-4)

Distributive Property

6x^2-8x+9x-12

Simplify

6x^2+x-12

To find the Perimeter you have to add both sides

2x+3+3x-4

5x-1

A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 ​respondents,
RoseWind [281]

Answer:

The statement that​ "the margin of error was given as \pm5 percentage​ points" means that the population proportion is estimated to be with a certain level of confidence, within the interval \hat{p} \pm 0.05 ; where \hat{p}[tex] is the sample's proportion. The correct answer is C. The statement indicates that the interval [tex]0.14\pm0.05 is likely to contain the true population percentage of people that prefer chocolate pie.

Step-by-step explanation:

The margin of error for proportions is given by the following formula:

z_{\alpha /2}\times\sqrt{\frac{\hat{p}\times(1-\hat{p})}{n}}

Where:

z_{\alpha /2} is the critical value that corresponds to the confidence level; the confidence level being 1-\alpha,

\hat{p} is the sample's proportion of successes,

n is the size of the sample.

In this exercise we have that \hat{p}=0.14 and that the margin of error is 0.05.

Therefore if we replace in the formula to calculate the confidence interval we get:

\hat{p}\pm 0.05=0.14\pm0.05=(0.09, 0.19)

Which means that the true population proportion is estimated to be, with a certain confidence level, within the interval (0.09, 0.19).
