180x=2(30÷3)+17-5•11+2÷1 = ?

Simplify the right side:

180x = 2(10) + 17 - 55 + 2 =

180x = 20 + -36 =

180x = -16

Now divide both sides by 180:

x = -16 /180

x = -4/45 or -0.0888

Answer:

x = -4/45

Step-by-step explanation:

180x=2(30÷3)+17-5•11+2÷1

We need to simplify the right hand side. The first step is the parentheses

180x=2(10)+17-5•11+2÷1

Then multiply and divide, working left to right from the equals sign.

180x=20+17-5•11+2÷1

180x=20+17-55+2÷1

180x=20+17-55+2

Now we add and subtract working left to right from the equals sign.

180x=37-55+2

180x =-18+2

180x = -16

Divide each side by 180

180x/180 = -16/180

x = -4/45

Lengths of full-term babies in the US are Normally distributed with a mean length of 20.5 inches and a standard deviation of 0.9

mash [69]

Answer:

66.48% of full-term babies are between 19 and 21 inches long at birth

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.

Mean length of 20.5 inches and a standard deviation of 0.90 inches.

This means that $\mu = 20.5, \sigma = 0.9$

What percentage of full-term babies are between 19 and 21 inches long at birth?

The proportion is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 19. Then

X = 21

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

$Z = \frac{21 - 20.5}{0.9}$

$Z = 0.56$

$Z = 0.56$ has a p-value of 0.7123

X = 19

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

$Z = \frac{19 - 20.5}{0.9}$

$Z = -1.67$

$Z = -1.67$ has a p-value of 0.0475

0.7123 - 0.0475 = 0.6648

0.6648*100% = 66.48%

66.48% of full-term babies are between 19 and 21 inches long at birth

Liam has purchased a fee-for-service health insurance plan from Leroux Health Insurance. Plan A includes a $248.00 monthly premi

Lerok [7]

Liam will only have to pay $211 per month for health care related feed this year because the annual deductibles will only be in effect if he continues to visit his physician and chiropractor regularly. This will put the insurance company at ease that he is at his most healthy state.
