If the cone has the same width with the cup, the height of the cone will be 6 inches.
<h3>How to find the volume of cylinder and cone?</h3>
The cup is cylindrical.
Therefore,
volume of the cup = πr²h
where
Hence,
volume of the cup = π × 1.5² × 2 = 4.5π
If the cone has the same width of the cup, the height of the cone can be calculated as follows;
4.5π = 1 /3 πr²h
4.5π = 1 / 3 × π × 1.5² × h
4.5π = 0.75πh
h = 4.5π / 0.75π
h = 6 inches

i really cant explain this
Answer:
Step-by-step explanation:
α + β = -b/a
αβ = c/a
α² + β² = (α + β)² - 2αβ
Answer:
1/5? 0.2?
Step-by-step explanation:
Answer:
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
Step-by-step explanation:
The scenario presented can be modeled by a binomial model;
The probability of success is, p = 0.65
There are n = 80 independent trials
Let X denote the number of drivers that wear a seat belt, then we are to find the probability that X is greater than 42;
Pr(X > 42)
In this case we can use the normal approximation to the binomial model;
mu = n*p = 80(0.65) = 52
sigma^2 = n*p*(1-p) = 18.2
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
