Answer:
Step-by-step explanation:
as Area of triangle is=1/2 base*height
Given
area=70
height=h=8
base lenght=?
put values in above formula for unkown
70=1/2 (8*b)
70=4*b
b=70/4
b=17.5 units
Answer:
μ = 1.877
Step-by-step explanation:
Data provided in the question:
Number of data samples, n = 10
Data: 2.18, 2.03, 1.56, 1.09, 1.56 ,2.28 ,1.62 ,2.02 ,2.11 ,2.32
Now,
Mean is calculated using the formula as:
Mean, μ =
or
Mean, μ =
or
Mean , μ = 
or
Mean , μ = 1.877
Assuming the highest score for a test is 100.
Highest possible total scores for 4 tests = 71 + 78 + 81 + 100 = 330
Highest possible average score for 4 tests = 330 ÷ 4 = 82.5
Answer: 82.5
