(3 * 4)^3 * 8 + 8 / 4

12^3 * 8 + 8 / 4

1728 * 8 + 8 / 4

13824 + 8 / 4

13832 / 4

3458

Your answer is 3458

Donte scored 55 on his mastery exam. What percent did Donte score?
masha68 [24]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete. First and foremost, to be able to solve this, we need to know the total marks of the examination.

Let's assume that the total marks for the exam is 80. Since Donte scored 55 on his mastery exam, the percent that he score will be:

= 55/80 × 100

= 68.75%

Suppose the true proportion of high school juniors who skateboard is 0.18. If many random samples of 250 high school juniors are
madreJ [45]

Answer:

0.024

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

Suppose the true proportion of high school juniors who skateboard is 0.18.

This means that p = 0.18

Samples of 250 high school juniors are taken

This means that n = 250

By how much would their sample proportions typically vary from the true proportion?

This is the standard error, so:

s = \sqrt{\frac{p(1-p)}{n}}

s = \sqrt{\frac{0.18*0.82}{250}}

s = 0.024

So 0.024 is the answer.

PLEASE HELP ASAP!!!! 50 POINTS!!
Kamila [148]

Answer:

Hope this helps!!

Step-by-step explanation:

2ya and 2yb where a and b have no common factors and a and b are polynomaals

a=(x+2)(x+3)

b=(x+4)(x+5)

no common factors betwen a and b

so

2ya=2y(x+2)(x+3)=2yx²+10xy+12y

2yb=2y(x+4)(x+5)=2yx²+18xy+40y

the 2 polynomials  are  2yx²+18xy+40y and 2yx²+10xy+12y
