Answer:

To answer the question, we need a radius or diameter. For know, I hope this equation helps.

Step-by-step explanation:

C=2π<em>r</em>

Circumference = 2 (pi) radius

For your problem, it says to use 3 for pi.

C=2(3)<em>r</em>

*If you have the diameter, but not the radius, divide that number by 2. Your radius is half the diameter.

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.

Anyone know how to solve this step by step?

ira [324]

Answer:

-1/2 or x=2

Step-by-step explanation: The first step you need to do in getting your answer is factoring ,you will factor the left side of the equation first:

(2x+1)(x-2)=0

Next, you will set the factors to equal to "0":

2x+1=0 x-2=0

Then you'll proceed to solve the problem using the basic algebraic equation problem solving steps .When you do this you'll be left with answers of x=-1/2 and x=2
