Answer:
76.14 m
Step-by-step explanation:
create a proportion of height/shadow equals height/shadow
3.2/1.66 = h/39.5
cross-multiply:
1.66h = 39.5(3.2)
1.66h = 126.4
h = 76.14
Answer:
1 - Copy and complete this table for y = 2x
x = -3 | y = -6
x = -2 | y = -4
x = -1 | y = -2
x = 0 | y = 0
x = 1 | y = 2
x = 2 | y = 4
x = 3 | y = 6
2 - Copy and complete this table for y = 2x - 3
x = -2 | y = -7
x = -1 | y = -5
x = 0 | y = -3
x = 1 | y = -1
x = 2 | y = 1
x = 3 | y = 3
x = 4 | y = 5
x = 5 | y = 7
Step 1: List the numbers in order (Least - Greatest): 2, 2, 5, 5, 19, 19, 25, 25, 28
Step 2: Find the middle number: <span>2, 2, 5, 5, 19, 19, 25, 25, 28
Answer: 19
(Information for further questions): If there are 2 middle numbers, average them. (Add them up and divide by 2)</span>
Mean absolute deviation is the average of the sum of all deviations of the terms from the average of the terms...
mean=(5+9+9+11+16)/5=10
mad=[(10-5)+(10-9)+(10-9)+(11-10)+(16-10)]/5=2.8
