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:
About -2
Step-by-step explanation:
I can estimate that the answer is about -2. There isn't really a way to explain this, as it is an estimation and not the exact answer.
To write a fraction in to a decimal, we carry out the long division. We divide the numerator with the denominator.
In the question above, we first form the fraction.
<span>5 Over 96 = 5/96
= 5 </span>÷ 96
<span> = 0.052083333
To the nearest hundredth, the answer is 0.05 </span>
