Answer:
the probability is 69.15%
Step-by-step explanation:
We have that the mean is 38 inches (m) and the standard deviation is 2 inches (sd), so we are asked:
P (x <39)
P ((x - m) / sd <(39 -38) /2)
P (z <0.5)
If we look in the normal distribution table we have to:
P (x <39) = 0.6915
That is, the probability is 69.15%
D. 45 and can you answer my history please ASAP
I’m pretty sure the answer is B because
8X- 4Y = -16 and it shows that in the equation of number B and if I’m wrong please correct me
A is the only option so that is the answer, i guess.
The answer is 1,000 and 9,000
