"How much do students pay, on average, for textbooks during the first semester in college? From a random sample of 400 students

dezoksy [38]

Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

Step-by-step explanation:

Since we have given that

Sample size = 400

Mean = $357.75

Standard deviation = $37.89

At 95% confidence level, z = 1.96

We first find the margin of error.

Margin of error is given by

$z\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{37.89}{\sqrt{400}}\\\\=3.71$

95% confidence interval would be

$\bar{x}\pm \text{margin of error}\\\\=357.75\pm 3.71\\\\=(357.75-3.71,357.75+3.71)\\\\=(354.04,361.46)$

Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

I need help .. so can somebody help me please ? what two number and get 10 and -24 ?

Trava [24]

What 2 numbers do you multiply to get 10? In other words, what number can you multiply with another number to get 10?

The formula to solve this would be:

X x Y = 10

There are at least two combinations of two numbers that you can multiply together to get 10.

For your convenience, we have made a list of all the combinations of two numbers multiplied by each other that will make 10:

<span>1 x 10 = 10
2 x 5 = 10
5 x 2 = 10
10 x 1 = 10
</span>

Step-by-step explanation:

34 = -(m + 3)

34 = -m - 3

+ 3 = -m + 3

37 = -m
