Answer:

y ≥ 3x +4

Step-by-step explanation:

The line is solid, so the inequality will include the "or equal to" case. The shading is above the line, so values of y greater than or equal to those on the line are in the solution set. The only choice with the correct (≥) inequality symbol is ...

y ≥ 3x +4

Pennies made before 1983 are 97% copper and 3% zinc, whereas pennies made after 1983 are 3% copper and 97% zinc. listed belo

The table in the attached figure

Pennies made before 1983
Part a) find the mean
we have
[3.1047,3.1082, 3.1582, 3.0776, 3.1276, 3.1035]
Mean 1=[3.1047+3.1082 + 3.1582 + 3.0776 + 3.1276 + 3.1035]/6
Mean 1=3.1133 grams

the answer part a) is
The mean weight of the pennies made before 1983 is 3.1133 grams.

Part b)
to find the Median, place the numbers in value order and find the middle.
[3.1047,3.1082, 3.1582, 3.0776, 3.1276, 3.1035]
[3.0776, 3.1035, 3.1047,3.1082, 3.1276, 3.1582]
(3.1047+3.1082)/2=3.10645 grams

the answer part b) is
The median weight of the pennies made before 1983 is 3.10645 grams.

Pennies made after 1983
Part c) find the mean
we have
[2.4842, 2.4828, 2.5024, 2.4997, 2.4907, 2.4956]
Mean 2=[2.4842 + 2.4828 + 2.5024 + 2.4997 + 2.4907 + 2.4956]/6
Mean 2=2.4926 grams

the answer part c) is
The mean weight of the pennies made after 1983 is 2.4926 grams.

Part d)
to find the Median, place the numbers in value order and find the middle
[2.4842, 2.4828, 2.5024, 2.4997, 2.4907, 2.4956]
[2.4828, 2.4842, 2.4907, 2.4956, 2.4997, 2.5024]
[2.4907 +2.4956]/2=2.49315

the answer part d) is
The median weight of the pennies made after 1983 is 2.49315 grams.

Part e) compare the means
Find the percentage difference
 the percentage difference is the difference between the new value and the old value, divided by the old value
so
new value=2.4926 grams
old value=3.1133 grams
[3.1133-2.4926]/3.1133------> 0.20-----> 20%
that means
the difference in the means is considerable to be greater than 5%
