Answer:
B
Step-by-step explanation:
Answer:
anything below 136.5 or above 155.5
Step-by-step explanation:
the critical value from a Z distribution for the 99% confidence level is 2.576
so we just need to compute
146 + 2.576(34/sqrt(85))
and
146 + 2.576(34/sqrt(85))
If P is a midpoint of DE, then:
DP + PE = DE and DP = PE → 2DP = DE
We have:
DP = 3x + 2 and DE = 10x - 12
Substitute:
2(3x + 2) = 10x - 12 |use distributive property
(2)(3x) + (2)(2) = 10x - 12
6x + 4 = 10x - 12 |subtract 4 from both sides
6x = 10x - 16 |subtract 10x from both sides
-4x = -16 |divide both sides by (-4)
x = 4
Substitute the value of x to the equation DP = 3x + 2:
|DP = 3(4) + 2 = 12 + 2 = 14
Answer: DP = 14 units
It is 19 because 53 I know I was guessing Bc Idk Im annoying
