Answer and step-by-step explanation:
5. To arrange it, find its value first:
4 - 6 = -2
-4 + 6 = 2
-4 - 6 = -10
So to arrange it from the least to greatest, it would be:
-10 , -2, 2 = c => a => b
8. To know which one have the least solution, calculate all of it first:
a. x + 5 = 13
Subtract both side by 5
x = 13 - 5
x = 8
b. -6x = -30
Divide both side by -6
-6x / -6 = -30/-6
x = 5
c. x / 4 = 18
x = 18 * 4
x = 72
d. x - 2 = -11
x = -11 + 2
x = -9
So d. have the least value (-9)
9. a. 10x - 4x = 6x
b. -15n + 3n = -12n
c. 7.5y + 1.6y = 9.1y
d. m + 4 - 2m = m - 2m + 4 = -m + 4
10. Student B are the students who invole in both piano and the band (As you can see it is in the middle of the diagram and it located in both circle (diagrams) so it would be both
Student G is the student who in the band because they only located in the band circle (diagram)
Hope those would help you :3

Answer:
a. The proportion of vehicle speeds were between 25 and 57 mph is 68.26%
b.The proportion of vehicle speeds exceeded 57 mph is 15.87%.
Step-by-step explanation:
a. To calculate what proportion of vehicle speeds were between 25 and 57 mph we would have to make the following calculations:
Probability that the vehicle speeds were between 25 and 57 mph is given by:
P(25≤x≤57)
=P(<u>25-41 </u>≤ <u>x-μ </u> ≤ <u>57-41)</u>
16 σ 16
=P(-1≤z≤1)
=P(z≤1)-P(z≤1)
=0.8413-0.1587
=0.6826
The proportion of vehicle speeds were between 25 and 57 mph is 68.26%
b. To calcuate what proportion of vehicle speeds exceeded 57 mph, we would have to make the following calculation:
Probability that vehicle speeds exceeded 57 mph is given by
P(x>57)
=P(<u>x-μ </u> > <u>57-41)</u>
σ 16
=P(z>1)
=1-P(z≤1)
=1-0.8413
=0.1587
The proportion of vehicle speeds exceeded 57 mph is 15.87%.
So from 1986 you Subtract total percentage 24.65% an $48 And the answer is a
