You know that at 10:00, there are 304 ounces; at 12:00, there are 228; at 3:00, there are 114 ounces; and so on. You can convert these to be like points on a graph: (10,304), (12,228), (15,114).

If you find the slope, then you will have the amount of water that leaks out the bucket every hour.

M=(228-304)/(12-10)= -38

Thus, 38 ounces of water leak from the bucket every hour.

Answer:

b. 2692 ft

Step-by-step explanation:

The relation of interest between the sides of the right triangle is ...

Tan = Opposite/Adjacent

Using the given numbers, that is ...

tan(32°) = (building height)/(4300 ft)

Multiplying by 4300 ft, we get ...

building height = (4300 ft)·tan(32°) ≈ 2686.9 ft

This is the height above the observer's eyes, so the height of the building above the ground is ...

2687 +5 = 2692 . . . . feet

The building is 2692 feet tall.

Plz help me with this

This question is not even trying to test your arithmetic. It's just testing
to see whether you know how to read numbers in words properly.

When you read numbers in words, the only time you ever say "and"
is for a decimal point. There are no decimals in this question, so the
"and" is not a part of any numbers.

The question gives you two numbers. The word "and" is the marker
that's BETWEEN them. The two numbers are 1,300 and 950 .

The first thing the question wants you to do is write the numerical
expression for all the words. That's (1300 - 950) / 4 .

The next thing you're supposed to do is"evaluate the expression" ...
find out what number it all boils down to. I don't think you'll have
any trouble with that now.

Suppose that 80 percent of all statisticians are shy, whereas only 15 percent of all economists are shy. Suppose also that 90 pe

Anna71 [15]

Answer:

37.21% probability that the person is a statistician.

Step-by-step explanation:

We have these following probabilities:

An 80% probability that a statistican is shy.

A 15% probability that an economist is shy.

At the gathering, a 90% probability that a person is an economist.

At the gathering, a 10% probability that a person is a statistican.

If you meet a shy person at random at the gathering. What is the probability that the person is a statistician?

This can be formulated as the following question:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = \frac{P(B).P(A/B)}{P(A)}$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

What is the probability that the person is a statistican, given that he is shy?

P(B) is the probability of the person being a statistican. So P(B) = 0.1.

P(A/B) is the probability of a statistican being shy, so P(A/B) = 0.8.

P(A) is the probability of a person being a shy. This is 15% of 90%(economists) and 80% of 10%(statisticans). So

$P(A) = 0.15*0.9 + 0.8*0.1 = 0.215$

Finally

$P = \frac{P(B).P(A/B)}{P(A)}$

$P = \frac{0.1*0.8}{0.215} = 0.3721$

37.21% probability that the person is a statistician.
