Ad libitum [116K]

Answer:

The third graph.

Step-by-step explanation:

The equations for the lines will be

P(x) = 2x-4

l(x) = -2x-4

When x = 0 both of these functions equal -4. The only graph where this happens is the third one.

You can check this by looking at the slopes and plugging in points.

Y+5=x+3 in standard form

podryga [215]

Answer: x-y=2

Step-by-step explanation:

y+5=x+3; move variable (x) to the left-hand side and change the sign.

y-x+5=3; move the constant to the right-hand side & change the sign

y+x=3-5; reorder the terms

-x+y=3-5; calculate

-x+y=-2; change the signs on both sides

x-y=2 is your answer! hope this helps!

The mean income per person in the United States is $44,500, and the distribution of incomes follows a normal distribution. A ran

Artist 52 [7]

Answer:

We conclude that the residents of Wilmington, Delaware, have higher income than the national average

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = $44,500

Sample mean, $\bar{x}$ = $52,500

Sample size, n = 16

Alpha, α = 0.05

Sample standard deviation, s = $9,500

a) First, we design the null and the alternate hypothesis

$H_{0}: \mu = 44,500\text{ dollars}\\H_A: \mu > 44,500\text{ dollars}$

We use one-tailed(right) t test to perform this hypothesis.

c) Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{52500 - 44500}{\frac{9500}{\sqrt{16}} } = 3.37$

b) Rejection rule

If the calculated t-statistic is greater than the t-critical value, we fail to accept the null hypothesis and reject it.

Now,

$t_{critical} \text{ at 0.05 level of significance, 15 degree of freedom } = 1.753$

Since,

$t_{stat} > t_{critical}$

We fail to accept the null hypothesis and reject it. We accept the alternate hypothesis. We conclude that the residents of Wilmington, Delaware, have higher income than the national average
