A Z-score or the standard score shows that how many standard deviation for a given measurement deviates from the mean. Total number of standard deviation is 2.5 from the mean 25.
Given information-
The value of the mean of the data is 15.
The value of the standard deviation of the data is 4.
The value of the sample mean is 25.
<h3>Normal distribution-</h3>
A function that represent the distribution of n numbers of random variables in a symmetrical bell shaped.
<h3>Z score-</h3>
A Z-score or the standard score shows that how many standard deviation for a given measurement deviates from the mean. The z score for the normal distribution of the data set can be given as,
Here is the sample mean of the data set, is the population mean of the data set and is the standard deviation.
Put the values,
Hence, total number of standard deviation is 2.5 from the mean 25.

Answer:300
Step-by-step explanation:25 cents each quarter so the equation would be 12 times 25.
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
Using DeMoivre's theorem, and the fact that any root in the first quadrant has argument between and , we get
so the missing value is 45.
Answer:
C.
Step-by-step explanation:
3 times 2 is 6, 2 times 5 is 10, 5 times 3 is 15. However you need 2 for each since there are 3 sets of two equal faces. So it will be 6+6+10+10+15+15
