The frequency table that shows the relative frequency of people older than 40 and don't visit the dentist is:
D. Visit Dentist Yearly Don’t Visit Dentist Yearly
Below 40 0.27 0.73
Above 40 0.57 0.43
<h3>What is the relative frequency required?</h3>
The relative frequency of those older than 40 and don't go annually to a dentist can be found as:
= Number of over 40 who don't go to dentist / Total of those over 40 surveyed
Solving gives:
= 13 / (17 + 13)
= 13 / 30
= 0.43

Answer:
x = 6, y = -8
Step-by-step explanation:
First we take the equations side by side and put them like this:
6x + 2y = 16
+ 2x - 2y = 32
8x = 48
Then solve for x.
x = 6
Then insert x back into either equation
2(5) - 2y = 32
10 - 2y = 32
solve for y,
y = -10
Answer:
<h2>x = 16.55</h2>
Step-by-step explanation:
1.06(12.95 + x) = 31.27
<u>Multiply the terms in the bracket</u>
That's
13.727 + 1.06x = 31.27
<u>Subtract 13.727 from both sides</u>
That's
13.727 - 13.727 + 1.06x = 31.27 - 13.727
1.06x = 17.543
<u>Divide both sides by 1.06</u>
That's
![\frac{1.06x}{1.06} = \frac{17.543}{1.06} \\ x = \frac{17.543}{1.06}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1.06x%7D%7B1.06%7D%20%20%3D%20%20%5Cfrac%7B17.543%7D%7B1.06%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B17.543%7D%7B1.06%7D%20)
We have the final answer as
<h3>x = 16.55</h3>
