Step-by-step explanation:
1. Add 5 to both sides.
2. Divide both sides by 2.
3. Take the square root of both sides.
![\sqrt[]{(x+\frac{3}{4})^2 } =\sqrt[]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%28x%2B%5Cfrac%7B3%7D%7B4%7D%29%5E2%20%7D%20%3D%5Csqrt%5B%5D%7B64%7D)
4. Subtract 
from both sides.
Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2
Answer: Two-sample t-test
Step-by-step explanation:
The Two-sample t-test is used to test the difference between two random and distinct population means. It help test whether the difference between the two populations is statistically significant.
In the case above the researcher wants to determine whether there is a difference in mean number of minutes of television viewing between men and women which makes it a Two-sample t-test.
