Step-by-step explanation:

piece 1: x

piece 2: x - 18

First you would subtract 2x - 18 = 108

Second you would add 108 + 18 = 2x

Third you would divide 126 divided by 2x = 63

So that would mean x = 63

The answers are 2. B, 3. D, 4. C, and 5. A.

Step-by-step explanation:

Step 1:

For question 2. $4+4n = -12.$

We subtract both sides by 4 to get

$4+4n-4 = -12-4, 4n = -16, n = -4$

For question 3. $4n=-12$ .

We divide the entire equation by 4 to get

$\frac{4n}{4} = \frac{-12}{4} , n = -3.$

Step 2:

For question 4. $\frac{n}{4} = -12.$

We multiply both sides by 4 to get

$\frac{n}{4} (4)= -12(4).$

$n = -48.$

For question 5. $\frac{n}{4} -4 = -12.$

We add 4 to both sides to get

$\frac{n}{4} -4 +4= -12+4, \frac{n}{4} = -8.$

$n = -32.$

So the answers are 2. B, 3. D, 4. C, and 5. A.

Answer:

The estimation for the number of newborns who weighed between 1724 grams and 5172 grams is 595.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 3448, \sigma = 862$
