1st number = x

2nd number = 3x

3rd number = 2x-10

x +3x + 2x-10 =92

6x - 10 = 92

6x =102

x = 102/6

x = 17

1st number = 17

2nd number = 17*3 = 51

3rd number = 17 *2 = 34-10 = 24

17 + 51 + 24 = 92

3 numbers are 17, 51 and 24

We'll use the Pythagorean Theorem
130^2 = side^2 +50^2
side ^ 2 = 16,900 -2,500
side ^ 2 = 14,400
side = square root (14,400)
side = 120 feet

What is the mean, median, mode, and range of 8, 35, 10, 12, 14?

Ivan

answer:

mean: 15.8

median: 12

mode: no mode

range: 27

step-by-step explanation:

first know how to find each of the above and what they are
mean = (avg) add all the numbers, then divide by the number of numbers
median = the middle number from increasing order
mode = the one that repeats the most
range = the difference between the largest and smallest number

8, 35, 10, 12, 14

<u>mean</u>

8 + 35 + 10 + 12 + 14 = 79

there are five numbers

79 / 5 = 15.8

<u>median</u>

put them from smallest to largest

8, 10, 12, 14, 35

12 is the median OR the middle number

<u>mode</u>

no number repeat, so no mode

<u>range</u>

35 - 8 = 27
