The first thing you need to do is classify all the men into 4 groups which are:
1) 30 and younger with facial hair: 4
2) older than 3 with facial hair: 5
3) 30 and younger with facial hair: 3
4) older than 30 without facial hair: 4
Question (a): Make a two-way table of the data. Of the men surveyed, how many were 30 and younger? How many did not have facial hair.
with facial hair without facial hair total
30 & younger 4 3 7
older than 30 5 3 8
total 9 6 15
From the data you can see that:
7 men were 30 and younger and 6 men did not have facial hair.
Question (b): Create a two-way relative frequency table that displays the relative frequency of the men 30 and younger and of the men older than 30 who had or did not have facial hair. Express your answer as decimals written to three decimal places.
with facial hair without facial hair total
30 and younger 4/15 3/15 = 1/5 7/15
older than 30 5/15 = 1/3 3/15 = 1/5 8/15
total 9/15 = 3/5 6/15 = 2/5 1
Question c: What percent of men older than 30 had facial hair?
The percent is equal to the relative frequency times 100% so in this case it is equal to (1/3) * 100% = 33.33%
Hope this helps!!! :)
4x³=756
x³=189
x=3 ³√7 should be acceptable

Answer: y = -13/2 = -6.500
so, only one
Step-by-step explanation:
Solving a compound inequality for this solution gives solution as;
13 daytime cameras and 7 flash cameras or 7 daytime cameras and 13 flash cameras
<h3>How to solve inequality problems?</h3>
Let the number of daytime cameras be x
Let the number of flash cameras be y
Thus, we have;
x + y = 20 ------(1)
Now, daytime cameras costs 2.75 dollars and the flash camera costs 4.25 dollars and you want to spend between 65 and 75 dollars, inclusive. Thus, the inequality to represent this are;
2.75x + 4.25y ≥ 65 and 2.75x + 4.25y ≤ 75
Solving the 3 compound inequalities simultaneously, we can say that the approximate values of the numbers of cameras are;
13 daytime cameras and 7 flash cameras or 7 daytime cameras and 13 flash cameras

Answer:
112in²
Step-by-step explanation:
Formulas: V = 
, V = lwh
Sub: v = 
Solve: 32
Sub: v = 4 x 4 x 5
Solve: 80
V = 80 + 32
V = 112
<u>The total volume of the figure is 112in²</u>
