You need to get an 85 on your last test
Answer:
1500 ft^2
Step-by-step explanation:
The area of a triangle is
, where b = base and h = height. In this triangle, we're given the base as 120 and the height as 25. 120 × 25 is 3000, and 3000 divided by 2 is 1500 ft^2.
Therefore, the answer is 1500 ft^2.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:
20.92
Step-by-step explanation:
Given the data:
X : 170, 160, 130, 165, 125
Standard deviation (s) :
s = √Σ((X - m)² / n)
m = mean
n = sample size
Mean , m = Σx/n
m = (170 + 160 + 130 + 165 + 125) / 5
m = 750/5
m = 150
((X - m)² / n - 1)
[(170-150)^2 + (160-150)^2 + (130-150)^2 + (165-150)^2 + (125-150)^2] / (5-1)
= 1750 / 4
= 437.5
s = √437.5
s = 20.9165
s = 20.92
