Answer:
E. 0.1401
Step-by-step explanation:
The mean here has been given as 20.9
The standard deviation sd = 4.7
Random sample n = 32
Sd/√n
= 4.7/√32
= 0.8309
Probability of x less than 20
= 20-20.9/0.8309
= -0.9/0.8309
= -1.083
P(z<-1.083)
When we go to the z table
= 0.1401
Therefore the probability is 0.1401 and the answer to this question is E.
Answer:
x =25
<B = 65 degrees
<C = 50 degrees
Step-by-step explanation:
65 + (3x-10) +2x = 180
Add like terms:
55 +5x = 180
Subtract 55:
5x = 125
Divide by 5:
x = 25
Substitute for x and solve
