Answer:56
Step-by-step explanation:
H: volume/3.14*(radius^2)
350/3.14*5^2
350/3.14*25
4.45
It would be written out as y=(2^3)X+7
Answer:
option B
Step-by-step explanation:
Given,
mean result (μ) = 65
standard deviation (σ)= 15
probability that student will score between 50 and 80
=
=
=
= P(Z < 1) - P(Z < -1)
Using z table,
= 0.8413 - 0.1587
= 0.6826
the correct answer is option B
