Hello, the measure of T is 34 when you round it to the nearest tenth
Step-by-step explanation:
3x + 12 - 2x + 8 + 5x
Solving like terms
x + 20 + 5x
20 + 6x
20 / 6 = x
Answer:
-2x+y=12
Step-by-step explanation:
linear equation
Answer:
H0: u1 - u2 = 0
H1: u1 - u2 ≠ 0
Step-by-step explanation:
This question requires us to state the hypothesis to be used for this test to know if males and females have the same amount of substance X. I have gone further to also calculate the test statistics too.
Null hypothesis:
H0: u1 - u2 = 0
Alternative hypothesis:
H1: u1 - u2 ≠ 0
X1 = 28, sd1 = 14.1, n1 = 75
X2 = 33, sd2 = 9.5, n2 = 50
We have a 2 tailed test
Alpha = 1-0.8812
= 0.1188
Critical value = 1.56
If z<-1.56 or z>1.56
Reject null hypothesis
Test statistic
= (28-33)/14.1²/75 + 9.5²/50
= -2.37
Therefore we reject the H0 because -2.37 is less than -1.56
Answer:
42 - 3 = 39 Is greater than 7 is
Hope this helps, even tho that's not 50 points, but i'm cool with it, I hope you get it correct
