Step-by-step explanation:
(a) A histogram is like a bar graph, but with ranges instead of values.
(b) The distribution is approximately uniform, with slightly more people at the younger and older ends than in the middle.
(c) The ages do not appear to come from a normal distribution. Normal distributions are bell-shaped, tall in the middle and short on the sides.
Answer:
Unit Price= $1.18
The error is that the contractor divided $99.12 by 7 and didn't multiply the 7 by the dozen (12) first, which lead to a mistake.

1) multiply 7x12 = 84
to get the total amount of gloves
2) divide 99.12 by 84
to get the unit price

eq. of line is y-5=1(x+3)
y=x+3+5
y=x+8
Step-by-step explanation:
total outcomes = 720
favourable outcomes =8
=8/720
=0.01111
Answer:
It will take 8 minutes for the temperature to reach 76°
Step-by-step explanation:
The expression for the total temperature in degrees at time t can be written as;
T=I+EM
where;
T=total temperature
I=initial temperature
E=temperature increase per minute
M=number of minutes
This can also be written as;
total temperature=initial temperature+temperature increase per minute×number of minutes
In our case;
T=76°
I=40°
E=4.5°
M=m
replacing;
76=40+(4.5×m)
4.5 m=76-40=36
(4.5 m)/4.5=36/4.5
m=8
It will take 8 minutes for the temperature to reach 76°
