Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205
The answer would probably 22.7. 18 is a perfect square, -10/5 is -2 and -13.4 is a regular decimal
Answer:
B) 12 cm^2
Step-by-step explanation:
4^2+?^2=5^2
16+?^2=25
?^2=9
?=3
A= (3*4*1/2)+(3*4*1/2)
A= 12 cm^2
