Answer:
2.86
Step-by-step explanation:
So I'm pretty sure we don't want the probability, just the zscore
to find the zsore subtract the mean and divide by the standard deviation
(93-87)/2.1= 2.86
Answer:
Step-by-step explanation:
If it have more than 2 divider its composite but its divider is only one and its self only its prime.1 isn't neither prime nor composite
C
D
Reason: their ratio is 1

Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
Look over all of the possible answers. If any of them contains either M or N or both, the result is irrational. There's one exception: N^2 produces a rational number because the radical disappears.
