Answer:
I cant see the whole thing But I think you're right
The answer is B. All real values of x such that x >_ 10
First Q.
If y = 6 and x = 10, then what's x if y = 18
y / x = 6 / 10 = 0.6
y / x = 18 / x = 0.6
x = 0.6 * 18
x = 10.6
Second Q.
If y = 22 and x = 8, then what's y if x = -16
y / x = 22 / 8 = 2.75
y / x = y / -16 = 2.75
y = 2.75 * -16
y = -44
The answer is 13+9u-5y... I THINK! x3
I circle all the positives and negatives, which you can detect by what is in front of the number, like 3y-8y, 8y is a negative. So, you subtract to get -5y.
The rest are positives, so you just add all the letters to what it matches to be, and constants too.
Then... You get your answer? I'm not sure how to get them in their exact order... can someone help me? x3
Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2
