How do I do this please help

Fittoniya [83]

The answer is c because when it's an inequality, x=4 that means that you need to put it in a numberline and since the numbers to your left will always be less than 4 the shaded part is on the right.

Answer:

The number of newborns who weighed between 1614 grams and 5182 grams was of 586.

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.

The mean weight was 3398 grams with a standard deviation of 892 grams.

This means that $\mu = 3398, \sigma = 892$

Proportion that weighed between 1614 and 5182 grams:

p-value of Z when X = 5182 subtracted by the p-value of Z when X = 1614.

X = 5182

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

$Z = \frac{5182 - 3398}{892}$

$Z = 2$

$Z = 2$ has a p-value of 0.9772

X = 1614

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

$Z = \frac{1614 - 3398}{892}$

$Z = -2$

$Z = -2$ has a p-value of 0.0228

0.9772 - 0.0228 = 0.9544.

Out of 614 babies:

0.9544*614 = 586

The number of newborns who weighed between 1614 grams and 5182 grams was of 586.

Solve for x. 5^11x=25^x+9

4vir4ik [10]

$\displaystyle\\
5^{11x}=25^{x+9}\\\\
5^{11x}=\Big(5^2\Big)^{x+9}\\\\
5^{11x}=5^{2(x+9)}\\\\
11x = 2(x+9)\\\\
11x = 2x+18\\\\
11x - 2x = 18\\\\
9x = 18\\\\
x = \frac{18}{9} = \boxed{2}$
