Answer:
correct answer comes out to be option D
Step-by-step explanation:
sample mean (μ) = $150
standard deviation (σ) = $20
for about 95% of monthly food expenditure are between
= μ - 2 σ , μ + 2 σ
= $150 - 2 × $20 , $150 + 2 × $20
= $110 , $ 190
so, the range comes out to be in between $110 and $ 190.
Hence, the correct answer comes out to be option D.

Answer:
6
Step-by-step explanation:
Integer a has to be -12, and integer b has to be -2, and when -12 is divided by -2 you get an answer of 6
V=(1/3)hpir^2
aprox
d=2r
d/2=r
d=24
r=24/2=12
V=2713
2713=(1/3)hpi(12^2)
2713=(1/3)hpi(144)
2713=48pih
divide both sides by 48
56.5208=hpi
aprox pi=3.14
divide both sides by 3.14
56.5208/3.14=h=18.0003
height=18cm
