Answer: The test statistic is t= -0.90.
Step-by-step explanation:
Since we have given that
n₁ = 50
n₂ = 25
So, s would be
So, the value of test statistic would be
Hence, the test statistic is t= -0.90.
ANSWER:
60°
EXPLAINATION:
= 2r + θ/360°× 2 x 227 x 21
64 = 2 x 21 + θ/360° x 2 x 22/7 x 21
64 = 42 + θ/360° x 44 x 3
64 - 42 = θ/360° x 11 x 3
22 = 33θ/90
θ=22×30/11
= 60°
7x+1 = (1/3)
2x + 2y = 28
Systems of equations.
Solve equation with single variable first.
7x+1 = (1/3) , x = (-2/21)
Substitute the value of x in second equation and solve for y.
2(-2/21) + 2y = 28, y = (296/21)
I’m assuming that isn’t the correct answer because you wrote the first equation incorrectly.
