Divide the fractions and simplify the answer 1/2 5/8

NeTakaya

To solve this let our write this fraction in terms.
$\frac{1}{2} 
$ / $\frac{5}{8}$

So now let change this problem as a multiplication problem. To change this to multiplication problem we have to flip our second term

$\frac{1}{2} * \frac{8}{5}$

So, now let's simplify the terms. So we get
$\frac{4}{5}$

Thus this is our final answer.

Let Z be the standard normal random variable. Use a probability calculator to answer the following questions: What is the probab

Softa [21]

Answer:

0.6826 = 68.26% probability Z will be within one standard deviation of average.

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.

What is the probability Z will be within one standard deviation of average?

This is the p-value of Z = 1 subtracted by the p-value of Z = -1.

Z = 1 has a p-value of 0.8413.

Z = -1 has a p-value of 0.1587.

0.8413 - 0.1587 = 0.6826

0.6826 = 68.26% probability Z will be within one standard deviation of average.

Due soon. Help!! Can somebody answer these 2 problems, please?

Licemer1 [7]

Answer:

2. x + 98 + 50 = 180

3. x = 32°

Step-by-step explanation:

<em>hey there,</em>

< 2. We know that there are 180 degrees in every triangle, and every triangle has only 3 angles. So when you add up those 3 angles, it will ALWAYS equal 180! And since we do not know one of the angles, we will just put the value of that angle as "x" into the equation.

3. Here, you should be able to find x! x = (180-(98+50)) = 32

The final answer is 32 degrees. >

<u>Hope this helped! Feel free to ask anything else.</u>
