1. 25

Step-by-step explanation:

First, you need to place the numbers in ascending order, meaning from smallest to largest.

You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25

Mean (average), just add the numbers up and divide by how many numbers you have

III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer

Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem

Mode, which number appears the most times repeated

i.  25 (range = the difference between the highest and lowest number)

ii. 30.41 (mean = sum of all numbers divided by the how many numbers there are)

iii. 6

iv. 35

v. 35

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65
