Answer:
f(4) = -1
Step-by-step explanation:
To find the function, or f, of x given a point, plug in the value of x for x in f(x). Then, find the corresponding y-value. The function of 4 is -1 in this example, so the final result looks like f(4) = -1.
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:
126 Inches are in 3.5 yards
