Answer:
370 mm sq
Step-by-step explanation:
bxh/2=area of triangle
so 20/2x37=370
Answer:
mean = 7
median = 7
range = 9
mid range = 7.5
Step-by-step explanation:
3, 5, 6, 7, 7, 9, 12
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
12 - 3 = 9
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
3, 5, 6, 7, 7, 9, 12
median = 7
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
(6 + 12 + 5 + 7+ 7 + 3 + 9) / 7 = 7
Mid range = (highest value + lowest value) / 2
(12 + 3) / 2 = 7.5
Answer:
x = 96
Step-by-step explanation:
x + x - 5 + x - 11 + x - 8 = 360
4x - 24 = 360
4x = 360 + 24
4x = 384
x = 96
Its a because you will add 1.25 and 0.75 because it says each and of course 18 would be what it equals
