The graphed line can be expressed by which equation?

earnstyle [38]

Answer:

The Answer is: y = 2/3x - 2/3

Step-by-step explanation:

Given points: (4, 2) and (-2, -2)

Find the slope m:

m = y - y1 / (x - x1)

m = 2 - (-2) / (4 - (-2))

m = 2 + 2 / (4 + 2)

m = 4 / 6 = 2/3

Use the point slope form, substitute the point (4, 2) and solve for y to get the point slope form:

y - y1 = m(x - x1)

y - 2 = 2/3(x - 4)

y - 2 = 2/3x - 8/3

y = 2/3x - 8/3 + 6/3

y = 2/3x - 2/3

Proof:

f(-2) = 2/3(-2) - 2/3

= -4/3 - 2/3 = -6/3 = -2, giving (-2, -2)

Hope this helps!! Have an Awesome Day!! :-)

You wish to compare the prices of apartments in two neighboring towns. You take a simple random sample of 12 apartments in town

Rom4ik [11]

Answer:

The value of P-value is 0.0472.

Step-by-step explanation:

We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.

Let $\mu_1$ = true average price of apartments in town A

$\mu_2$ = true average price of apartments in town B

So, Null Hypothesis, $H_0$ : $\mu_1=\mu_2$

Alternate Hypothesis, $H_A$ : $\mu_1\neq \mu_2$

The test statistics that have been used here is two-sample t-test statistics, i.e;

The test statistics given to us is 2.1

Now, the P-value of the test statistics is given by the following formula;

P-value = P( $t__n__1+_n_2-_2$ > 2.1)

= P( $t_2_5$ > 2.1) = 0.0236

In two-tailed test, P-value is calculated as = 2 $\times$ 0.0236 = 0.0472

Hence, the value of the p-value is 0.0472.
