Area of a trapezoid is found with the formula, A=(a+b)/2 x h.
I hope that helps u if not sorry:(
1/25
(5^2)^-3 x 5^4= 0.04 which is 1/25 in fraction form
Answer:
Yes
Step-by-step explanation:
First, we need to find how many cars out of the entire fleet fail the test
4/32 = x/150
Cross multiply to find x
32x = 150(4)
32x = 600
32x/32 = 600/32
x = 18.75
I'll round it to 19. So 19 out of 150 cars fail the test. Find the percentage of this and compare it to the 30% estimate
19 /150 = 0.127
0.127(100) = 12.7%
12.7% is obviously lower than 30% so yes it is strong evidence the percentage of the fleet out of compliance is different from their initial thought
Answer:
20 * 19.52 = 390.40
Thank you and please rate me as brainliest as it will help me to level up
