Answer:
I’m pretty sure it’s B)- Z
Step-by-step explanation:
18. The correct table must display the following information.
38% prefer turkey with mayonnaise 20% prefer turkey with mustard 24% prefer ham with mayonnaise 18% prefer ham with mustard
In tables Z and W, each table totals 50 people.
To find the relative frequencies of the data in these tables, divide each number in the table by 50.
In tables X and Y, each table totals 100 people.
To find the relative frequencies of the data in these tables, divide each number in the table by 100.
The only table which is a possible representation of the data collected is table Z.

Turkey
19 ÷ 50 = 0.38
10 ÷ 50 = 0.20
29 ÷ 50 = 0.58
Ham
12 ÷ 50 = 0.24
9 ÷ 50 = 0.18
21 ÷ 50 = 0.42
Total
31 ÷ 50 = 0.62
19 ÷ 50 = 0.38
50 ÷ 50 =1.00
It took me a minute, but I understand what it wants you to do.
a^2+b^2=c^2
Find the missing length on that one triangle to the left.
62^2+b^2= 99.2^2
Square the numbers.
3844+b^2= 9840.64
Subtract 3844 on both sides.
b^2= 5996.64
Square root it.
b= 77. 437975 round down to b= 77.4
Now, we can find the length of the other missing side. (x+2)
77.4^2+b^2= 112^2
5990.76+b^2= 12,544
Subtract 5990.76 on both sides.
b^2= 6553.24
Square root it.
b= 80.952085, round to b=81
Now, plug that in.
(x+2)= 81
Subtract 2 on both sides.
x=79 (about)
I hope this helps! Make sure to check my work.

-4 < x < 6
could also be : x > -4 and x < 6
