Answer:
N = 3
Step-by-step explanation:
I don't know what the whole thing above is, but just disregard that.
All it is here is cross multiplication.
So 28N = 21 * 4
Multiply...
28N = 84
And divide each side by 28
N = 3
Answer:

Answer:
(A)
Step-by-step explanation:
A)The degree of the function is odd, so the ends of the graph continue in opposite directions. Because the leading coefficient is positive, the left side of the graph continues down the coordinate plane and the right side continues upward.
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
It looks like the dot would be placed on about 12.4 or 12.45. I hope that this helped. And that means that the square root would be located at 153.76 or 155.0025.
