Help plsssssss WILL GIVE BRAINLIEST
ruslelena [56]

Answer: (1,2)

Step-by-step explanation:

I will help you..

Given:

-2x-5y=-12\\10x-4y=2

Lets cancel out the x term..

5(-2x-5y)=-12(5)\\=-10x-25y=-60

Now our system looks like this:

-10x-25y=-60\\10x-4y=2

Add.

-29y=-58\\y=2

plug in 2 for y

-2x-5(2)=-12\\-2x-10=-12\\-2x=-2\\x=1

Therefore the system is:

(1, 2)

If this helped consider marking brainiest.

Charra [1.4K]

Answer:

d. 0.0948 ± 4.032(0.0279)

Step-by-step explanation:

A 99% confidence interval for the coefficient of promotional expenditures is, First, compute the t critical value then find confidence interval.

The t critical value for the 99% confidence interval is,  

The sample size is small and two-tailed test. Look in the column headed es = 0.01 and the row headed in the t distribution table by using degree of freedom is here

for (n-2=5) degree of freedom and 99% confidence ; critical t =4.032

therefore 99% confidence interval for the slope =estimated slope -/+ t*Std error

= 0.094781123 -/+ 4.032* 0.027926367 = -0.017822 to 0.207384
