Answer: t = 10
Step-by-step explanation:m
Given that; n₁ = 10, n₂ = 10
ж₁ = 50, ж₂ = 30
Sˣ₁ = 20, Sˣ₂ = 20
Now using TEST STATISTICS
t = (ж₁ - ж₂) / √ ( Sˣ₁/n₁ + Sˣ₂/n₂ )
so we substitute our figures
t = ( 50 - 30 ) / √ ( 20/10 + 20/10 )
t = 20 / √4
t = 10
Answer:
(x, y) = (-1/4, -3/4)
Step-by-step explanation:
1. Write as a system
2x + 2y = 14x - 2y = -2
2. Eliminate one variable by adding the equations
2x + 2y = -2
14 x - 2y = -2
3. Divide both sides by 16
16x = -4
4. Substitute the value of x into the equation.
x = -1/4
5. Solve the equation
2(-1/4) + 2y = -2
6. A possible solution is
y = -3/4
7. Check the solution
(x, y) = (-1/4, -3/4)
8. Simplify the expression
2(-1/4) + 2(-3/4) = 14(1/4) - 2(-3/4) = -2
9. The ordered pair is a solution
-2 = -2 = -2
10. (x, y) = (-1/4, -3/4)
