Answer:
The runner’s time is 3.18 minutes
Step-by-step explanation:
Mathematically;
z-score = (x-mean)/SD
In this question, we have the z-score but we want to calculate x
From the question
z-score = -1.76
mean = 4.5 minutes
SD = 0.75 minutes
x = ?
Substituting these values, we have that
-1.76 = (x-4.5)/0.75
0.75(-1.76) = x - 4.5
-1.32 = x - 4.5
x = 4.5 -1.32
x = 3.18
The correct answer that would best complete the given statement above would be the term "solve". So here is the complete statement. <span>The algebraic process you use to isolate a variable in order to find what values, numbers, etc. will make an equation true. You solve the equation. Hope this answer helps. Have a great day!</span>
Answer:
8 and -3
Step-by-step explanation:
We need to list several factors of -24 that add up to 5.
After trying several possibilities we ge
8 x (-3) =24 and
8 + (-3) = 5
