Hi!
Let's start with the mean.
The mean is all the numbers added together, divided by how many numbers there are.
13+16+16+10+6+12+4+12+16=105
there are 9 numbers so..
105/9 = 11.7
The mean is 11.7
Find the median.
The median is the number in the middle of the data set when the numbers are in numerical order.
4, 6, 10, 12, 12, 13, 16, 16, 16
The median is 12.
Find the mode.
The mode is the number that is repeated the most.
4, 6, 10, 12, 12, 13, 16, 16, 16
The mode is 16
Find the range.
The range is the difference of the smallest number from the biggest number.
16 - 4 = 12
The range is 12
The answer is 11.7, 12, 16, 12
Hope this helps! :)
3+4+1 for each class so it's 8
8 x 6 for all the classrooms so it's 48. The school buys 48 games
Using the normal distribution, it is found that 95.15% of students receive a merit scholarship did not receive enough to cover full tuition.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation for the amounts are given as follows:

The proportion is the <u>p-value of Z when X = 4250</u>, hence:


Z = 1.66
Z = 1.66 has a p-value of 0.9515.
Hence 95.15% of students receive a merit scholarship did not receive enough to cover full tuition.

If the triangles are similar, the base should be 24 inches. The legs on the first triangle are 12 inches. To get 36 inches (the other triangle), we multiply 12 by 3. 12 x 3 = 36. Because you did that to the legs, you must also do it to the base. 8 x 3 = 24. Therefore, the base of the second triangle is 24 inches.
