Complete the paragraph below. The standard deviation is used in conjunction with the​ ______ to numerically describe distributio
Bumek [7]

Answer:

The standard deviation is used in conjunction with the​ mean to numerically describe distributions that are bell shaped. The​ mean measures the center of the​ distribution, while the standard deviation measures the​ spread of the distribution.

Step-by-step explanation:

Problems of normally distributed samples can be 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 mean is the average value of the measures while the standard deviation measures how spread the measures are from the mean. So

The standard deviation is used in conjunction with the​ mean to numerically describe distributions that are bell shaped. The​ mean measures the center of the​ distribution, while the standard deviation measures the​ spread of the distribution.

solniwko [45]

Answer:

17 and 18

Step-by-step explanation:

Writing every 2 digit number gives us :

10-99 including 10 and 99

For the first one we are looking for numbers where the number 3 appears only once so 33 would be invalid.

13,23,30,31,32,34,35,36,37,38,39,43,53,63,73,83,93

There are 17 2-digit numbers that have 3 exactly once

For the second one we are looking for number where the number 3 appears a minimum of once so 33 would be valid :

13,23,30,31,32,33,34,35,36,37,38,39,43,53,63,73,83,93

There are 18 2-digit numbers that have 3 at least once

Hope this helped and have a good day

Solve for q<br> (Please show all work thank you:))
Masja [62]

Answer:

q = ±  \frac{5}{4\sqrt{p} }

Step-by-step explanation:

We are to solve for q in:

16pq² = 25

q² = \frac{25}{16p}

\sqrt{q^2} = ±\sqrt{\frac{25}{16p} } = ± \frac{5}{4\sqrt{p} }
