Answer: The hieght is 12.7 inches

Step-by-step explanation:

r=d/2

3.5/2=r

r=1.75

v=pir²h

122.5 =piR²h

122.5=pie1.75²h

The frist thing to solve for r sense exponents come before multiplication in bedmask

122.5 =pi3 .06g

so then it's pie times r

122.5=9.61 *h

122.5/9.61=h

12.7=h

REY [17]

Mean = 72

First round = 72-3 = 69
Second round = 72-1 = 71
Third round = 76

Explanation:
Total score = 72*3 = 216

69+71+x = 216
140+x = 216
x = 76

Nico ordered a side of rice and beans for $2.50 and x tacos, each priced at $3.50, including tax. To determine the total cost of

Talja [164]

The domain of a function is the set of values that can be used for x.
Here, x represents the number of tacos.
He can order no taco, so x = 0.
He can order 1 taco, where x = 1.
He can order 2 tacos, so x = 2.
He cannot order a fraction of a taco, so x cannot be a mixed numeral.
He can order as many tacos as he wants, so x can be any whole number, 0 to infinity.
The domain is all whole numbers.

g The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control

Rudiy27

Answer:

0.1426 = 14.26% probability that at least one of the births results in a defect.

Step-by-step explanation:

For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability that a birth results in a defect is independent of any other birth. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).

This means that $p = \frac{1}{33}$
