Word problem: Today the temperature dropped 13 °F. After this drop, the temperature was 74 °F. What was the original temperature outside before the drop?

Subtraction problem: x °F - 13 °F = 74 °F

Solve: x - 13 = 74
x - 13(+13) = 74 + 13
x = 87 °F

Given:

mean, u = 0

standard deviation σ = 1

Let's determine the following:

(a) Probability of an outcome that is more than -1.26.

Here, we are to find: P(x > -1.26).

Apply the formula:

$z=\frac{x^{\prime}-u}{\sigma}$

Thus, we have:

$\begin{gathered} P(x>-1.26)=\frac{-1.26-0}{1} \\ \\ P(x>-1.26)=\frac{-1.26}{1}=-1.26 \end{gathered}$

Using the standard normal table, we have:

NORMSDIST(-1.26) = 0.1038

Therefore, the probability of an outcome that is more than -1.26 is 0.1038

(b) Probability of an outcome that

Round 789 to the nearest 10

elena-14-01-66 [18.8K]

Rounding 789 nearest to tens will be 790.

Step-step Explanation:

Let's know how to round any number nearest to tens (Rules):-

We know tens place in any no. from left is at second place and number right to tens place need to be changed as:-

If last digit is 0, then we don't have to do any rounding, because it is already to the ten.

We round the no. down to the nearest ten if the last digit in the no. is 1, 2, 3, or 4

We round the no. up to the nearest ten if the last digit in the no. is 5, 6, 7, 8, or 9.

The mean number of hours of part-time work per week for a sample of 526526 college students is 2828. If the margin of error for

sveta [45]

Answer:

The 99% confidence interval for the mean number of hours of part-time work per week for all college students is between 25.8 and 30.2.

Step-by-step explanation:

A confidence interval has the following format.

$\mu_{x} \pm M$

In which $\mu_{x}$ is the mean of the sample and M is the margin of error.

In this problem, we have that:

$\mu_{x} = 28, M = 2.2$

$\mu_{x} - M = 28 - 2.2 = 25.8$

$\mu_{x} + M = 28 + 2.2 = 30.2$

The 99% confidence interval for the mean number of hours of part-time work per week for all college students is between 25.8 and 30.2.
