Answer:

Step-by-step explanation:

Writing decimals in expanded form simply means writing each number according to its place value. This is done by multiplying each digit by its place value and adding them together. Let's look at an example: 2.435. In words, we would say this as two and four hundred thirty-five thousandths.

nekit [7.7K]

Answer:

Step-by-step explanation:

j + p > 175

j = 34

34 + p > 175 <== ur inequality

p > 175 - 34

p > 141.......so she spent at least 141.01...because it has to be greater then 141...but cant be equal.

Find the average value of the following numbers 87, 79, 84, 70, 90

dem82 [27]

Explanation

the average is calculated by dividing the sum of the values in the set by their number.

Step 1

Let

$\begin{gathered} \text{set}=\lbrace87,79,84,70,90\rbrace \\ the\text{ sum of the values is=87+79+84+70+90}=410 \\ n\text{umber of values= 5} \end{gathered}$

Step 2

apply the equation

$\text{Average}=\text{ }\frac{the\text{ sum of the values}}{\nu mber\text{ of values}}=\frac{410}{5}=82$

so, the answer is 82

A physical fitness association is including the mile run in its high school fitness test. The time for this event is known to po

vlabodo [156]

Answer:

This probability is the p-value of Z given $Z = \frac{X - \mu}{\sigma}$ , considering X as less than X seconds, $\mu$ as the mean and $\sigma$ as the standard deviation.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

Mean $\mu$ , standard deviation $\sigma$ .

Find the probability that a randomly selected high school student can run the mile in less than X seconds.

This probability is the p-value of Z given $Z = \frac{X - \mu}{\sigma}$ , considering X as less than X seconds, $\mu$ as the mean and $\sigma$ as the standard deviation.
