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:
<h2>A = 60 in²</h2><h2 />
Step-by-step explanation:
a = 12 in
b = 8 in.
h = 6 in.
<u>plugin values into the formula:</u>
A = 1/2 h(a + b)
A = <u>(12 + 8) </u> x 6
2
A = 60 in²
Answer: -21 + -18t
Step-by-step explanation:
-3(7+6t)
-3 x 7= -21
-3 x 6t= 18t
Answer:
y = (-5/7) x + 1
Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
5x + 7y = 7
To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1
Hope this helps :)
