Step-by-step explanation:

volume of cone = 1/3 πr²h

1/3× 22/7×3×3×10

1 ×22 ×3×3×10

The function rule T(m)=450-8m represents the amount of water T(m) (in liters) in a holding tank after being drained at a rate of

suter [353]

Well they give you the equation and they want you to solve for time given that you know the amount of water in the tank. They tell you T=274 and that

T=450-8m so using the value T=274 in the equation to the left gives you:

274=450-8m subtract 450 from both sides

-176=-8m divide both sides by -8

22=m

So 22 minutes have passed when there is 274L remaining...

AysviL [449]

Answer:

The variance for the number of tasters is 4.2

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they are tasters, or they are not. The probability of a person being a taster is independent of any other person. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The variance of the binomial distribution is:

$V(X) = np(1-p)$

It is known that 70% of the American people are "tasters" with the rest are "non-tasters". Suppose a genetics class of size 20

This means that $p = 0.7, n = 20$

$V(X) = np(1-p) = 20*0.7*0.3 = 4.2$

The variance for the number of tasters is 4.2

Micah takes a job with a starting salary of $78,000 for the first year. He earns a 4% increase each year. How much does Micah ma

zzz [600]

So his job has a starting salary of $78,000 and he gets a 4% increase each year. 4% of 78,000 is 3120 since 3120 divided by .04 equals 78,000, and 78,000+3120 = 81120 x 7= 567,840. So every year he can make $81120 and multiply that by 7, Mica would earn $567,840 every 7 years with the 4% increase in his salary every year.
