Answer:
HK = 16
Step-by-step explanation:
12^2+x^2=20^2
x = HK
When a number is raised to a power it is multiplied by itself so the number gets larger. Because the answer is a fraction, this means the power is a negative value.
Find the number 5 has to be raised to be 125 and then make is negative:
5 x 5 x 5 =125
The answer would be a = -3
Answer:
2
2x −3x
Step-by-step explanation:
-9u + 3u = 9 + 9
-6u = 18
u = -18/6
u = -3
Thus, u is equal to -3
Answer:
0.242
Step-by-step explanation:
p = 0.08, q = 1 − p = 0.92, and n = 1000.
The mean and standard deviation are:
μ = p = 0.08
σ = √(pq/n) = 0.00858
The z score is:
z = (x − μ) / σ = -0.70
Using a calculator or z score table, the probability is:
P(Z < -0.70) = 0.242
