Answer:

The correct statements are 1, 3, and 4

Step-by-step explanation:

This is a radio problem

so now to understand the situation, we need to know what do we have -- 4 green cup and 2 white cup, OR 1 white cup with every 2 green cup.

Basically, with every 2 green cup, is 1 white cup. Therefore the radio of green to white is 2:1 So the first option is correct.

Now the second option is wrong because there isn't 1 green cup with every 2 white cup, it's the opposite. so this is wrong.

Now the third statement is correct because we have 4 green and 2 white which makes the ratio of 4:2

The fourth is correct, it is simply another way of saying statement one - every 2 green comes with a white.

The last one is wrong because every 2 green goes with 1 white not 4.

balandron [24]

Answer:

The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.

Step-by-step explanation:

A student working on a report about mathematicians decides to find the 98% confidence interval for the difference in mean age at the time of math discovery for Greek mathematicians versus Egyptian mathematicians. The student finds the ages at the time of math discovery for members of both groups, which include all Greek and Egyptian mathematicians, and uses a calculator to determine the 98% confidence interval based on the t distribution, <u>the entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.</u> There is no as such explanation of this scenario, its just the answer mentioned above.

A 40-foot y’all monument sits on top of a hill. Eye is standing at a point on the hill and observes the top of the monument at a

aleksley [76]

Answer:

54.8 feet

Step-by-step explanation:

We assume that the distance of interest is the direct line distance from the observation point to the bottom of the monument, segment PH in the diagram below.

This can be found using the Law of Sines.

∠PMH is the complement of the angle of elevation to the top of the monument, so is 40°.

∠MPH is the difference in the angles of elevation, so is 28°.

The Law of Sines tells us the ratio of side lengths is the same as the ratio of the sines of the opposite angles, so ...

PH/MH = sin(∠PMH)/sin(∠MPH) = sin(40°)/sin(28°)

Multiplying by MH, we can find the length of PH:

PH = (40 ft)(sin(40°)/sin(28°)) ≈ 54.7669 ft

PH ≈ 54.8 ft . . . . the distance Pete must climb to reach the monument.
