How do you solve the inequality, and graph the solution of 2n

How many 4-digit numbers can be made from the digits 2, 3, 4, 5, 6, 7 if no digit is repeated in the same number?

jonny [76]

THis equals the number of permutations of 4 from 6.

= 6P4 = 6! / (6 - 4)! = 6! / 2! = 720/2 = 360 answer

Veseljchak [2.6K]

Answer:

0| 7, 9,9,9

1| 3,5,6

2| 0,6

3|

4| 4

Notation: For this case the first number represent the first digit and the second represent the second digit.

Step-by-step explanation:

For this case we have the following dataset given:

9,16,9,15,20,13,7,26,9,44

The first step is order the data on increasing way and we got:

7,9,9,9, 13,15, 16,20,26,44

And we can create the stem plot like this:

0| 7, 9,9,9

1| 3,5,6

2| 0,6

3|

4| 4

Notation: For this case the first number represent the first digit and the second represent the second digit

Suppose that in a certain population, individuals’ heights are approximately nor-mally distributed with parametersμ=70 andσ=3 in

ruslelena [56]

Answer:

a) 25.14% of the population is over 6ft tall.

b) Both are going to be normally distributed.

Centimeters: $\mu = 177.8, \sigma = 7.62$ cm

Meters: $\mu = 1.778, \sigma = 0.0762$ cm

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 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

Normally distributed with parameters $\mu = 70, \sigma = 3$ .
