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.
At the moment it’s in standard form. We can easily turn this into slope int form (y= mx + b) tho
3y= -18x -18
y= -6x - 6
I pretty sure the answer is c
Step-by-step explanation:
-10 or -20 satisfies the equation.
But when you substitute 10 in:
30-40<-50+8
-10<-42(wrong)
it's wrong
It's a probability problem to find the odds of picking a green or red
shirt out of the 10 shirts on Thursday, Friday and Saturday since you
have randomly already know you have picked a blue shirt on the other
days. Not sure if you have this as a multiple question problem as you didn't list any possible answers (A. 7/20, B. 5/47, C. 2/5, D. 4/125) to the question. A, B, C, D being like 7 chances out of 20, 5 chances out 47, 2 chances out of chances 5 or 4 chances out of 125 (example answers only).
Probability = Number favorable outcomes / total number of outcomes
