A line passes through the point (4,-2) and has a slope of 1/2 what is the value of a if the point (-4,a) is also on the line

Slav-nsk [51]

Answer: The value of a is -6.

Step-by-step explanation:

To do this we need to find the y-intercept first.

-2= 4(1/2) + b

-2=2+ b

-2 -2

b= -4 so now the y-intercept is -4 so we will now have the equation y= 1/2x -4

so now put -4 into the equation for x and solve for y.

y= 1/2(-4) -4

y = -6

Answer:

The standard deviation of the sample is 0.0064.

Step-by-step explanation:

The standard deviation of a sample of length n of a population with standard deviation $\sigma$ is given by the following formula:

$s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

61 randomly selected gas stations. This means that $n = 61$

The standard error of the mean is $0.05. This means that $\sigma = 0.05$ .

What is the standard deviation of the sample?

$s = \frac{\sigma}{\sqrt{n}} = \frac{0.05}{\sqrt{61}} = 0.0064$

The standard deviation of the sample is 0.0064.
