A set of data has the trend line modeled by the equation Y =1.5x + 11. What value of X corresponds to y =56?

erica [24]

Answer:

x = 30

Step-by-step explanation:

Plug in 56 in place of y, then solve for x.

56 = 1.5x + 11

Subtract 11.

45 = 1.5x

45/1.5 = x

KiRa [710]

Answer:

Null Hypothesis, $H_0$ : $\mu$ = 1,100 square feet

Alternate Hypothesis, $H_A$ : $\mu$ < 1,100 square feet

Step-by-step explanation:

We are given that the mean area of several thousand apartments in a new development is advertised to be 1,100 square feet.

A consumer advocate has received numerous complaints that the apartments are smaller than advertised.

<u><em>Let </em></u> $\mu$ <u><em> = mean area of several apartments.</em></u>

So, Null Hypothesis, $H_0$ : $\mu$ = 1,100 square feet

Alternate Hypothesis, $H_A$ : $\mu$ < 1,100 square feet

Here, <u>null hypothesis states that</u> the mean area of apartments are same as advertised.

On the other hand, <u>alternate hypothesis states that</u> the mean area of apartments are smaller than advertised.

So, this would be the appropriate null and the alternative hypothesis to test this claim.
