Answer 1

Answer:

[tex]n=\frac{8}{3}[/tex]  or  [tex]n = 2\frac{2}{3}[/tex]

Step-by-step explanation:

Multiply both sides of the equation by [tex]\frac{10}{3}[/tex]

[tex](\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})[/tex]

Simplify both sides of the equation.

[tex]n=\frac{8}{3}[/tex] or [tex]n = 2\frac{2}{3}[/tex]

hope this helps :)

A cat is stuck in a tall tree and needs to be saved by the Firefighters. The fire truck has a 35m ladder. The closest that it can get to the tree (because there are parked cars in the way) is 12m. The cat is in the tree, 39m up. Comment on the likelihood of the cat getting saved and justify your suggestion mathematically. (Show your work)

Answers

Answer:

Image attached

It is unlikely that the cat will be saved as the firefighters will be able to reach only up to 33 mm from the ground.

What is a Right angled Triangle ?

A right angled triangle is a triangle with one of its angle as 90 degree and Pythagoras theorem can be applied to determine the sides of the triangle.

The ladder height = 35 m

The horizontal distance of the ladder = 12m

The height at which the cat is stuck is 39 m

By Pythagoras theorem , the height up to which the firefighters can reach can be determined

h = [tex]\rm \sqrt {35^2 - 12^2}[/tex]

h = 32.8 ≈ 33 m

Therefore the height up to which the fire fighters can reach is 33m and the height at which the cat is stuck is at 39 m , the likelihood of the cat getting saved is not there.

Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes. Of course, if you took an actual poll you would only get one number (your sample proportion, p-hat). Imagine all the possible samples of 150 students that you could draw and the distribution of all the possible sample proportions you would get from them.
If I told you that we know that 35% of all students actually prefer to take classes online, how would you respond to the following?:
1. Discuss the conditions necessary to use the normal curve to model this sampling distribution and explain whether or not they are met.
2. If the normal model is appropriate for this distribution, what shape would you expect it to have?
3. If you were to use the normal model for this p-hat sampling distribution, what value would be at the center of your sampling distribution? In other words, what value would all of those sample proportions center around?
4. What would be the standard deviation of this sampling distribution?

Answers

Answer:

1. Since [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], these conditions are met.

2. Approximately normal.

3. 0.35

4. 0.0389

Step-by-step explanation:

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Let's say you want to poll a random sample of 150 students on campus to see if they prefer to take online classes.

This means that [tex]n = 150[/tex].

35% of all students actually prefer to take classes online

This means that [tex]p = 0.35[/tex]

1. Discuss the conditions necessary to use the normal curve to model this sampling distribution and explain whether or not they are met.

The conditions necessary are [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].

We have that

[tex]np = 150*0.35 = 52.5 \geq 10[/tex]

[tex]n(1-p) = 150*0.65 = 97.5 \geq 10[/tex]

Since [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex], these conditions are met.

2. If the normal model is appropriate for this distribution, what shape would you expect it to have?

By the Central Limit Theorem, approximately normal.

3. If you were to use the normal model for this p-hat sampling distribution, what value would be at the center of your sampling distribution? In other words, what value would all of those sample proportions center around?

The mean, which by the Central Limit Theorem, is [tex]\mu = 0.35[/tex].

4. What would be the standard deviation of this sampling distribution?

By the Central Limit Theorem,

[tex]s = \sqrt{\frac{0.35*0.65}{150}} = 0.0389[/tex]
