A large cable company reports the following:
80% of its customers subscribe to its cable TV service.
44% of its customers subscribe to its Internet service.
29% of its customers subscribe to its telephone service.
25% of its customers subscribe to both its cable TV and Internet service.
20% of its customers subscribe to both its cable TV and phone service.
23% of its customers subscribe to both its Internet and phone service.
15% of its customers subscribe to all three services.
Consider the chance experiment that consists of selecting one of the cable company customers at random. Calculate the following probabilities.
A) P(cable TV only).
B) P(Internet | cable TV).
C) P(exactly services).
D) P(Internet and cable TV only).
Answer:
[tex]P(Cable\ TV\ only) = 50\%[/tex]
[tex]P(Internet\ |\ cable\ TV) = 31.25\%[/tex]
[tex]P(exactly\ 2\ services) = 23\%[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = 23\%[/tex]
Step-by-step explanation:
Given
[tex]Cable\ TV = 80\%[/tex]
[tex]Internet = 44\%[/tex]
[tex]Telephone = 29\%[/tex]
[tex]Cable\ TV\ and\ Internet = 25\%[/tex]
[tex]Cable\ TV\ and\ Telephone = 20\%[/tex]
[tex]Internet\ and\ Telephone = 23\%[/tex]
[tex]All\ Services = 15\%[/tex]
Solving (a): A) P(cable TV only).
First, we calculate n(cable TV only)
This is calculated as:
[tex]n(cable\ TV\ only) = (Cable\ TV) - (Cable\ TV\ and\ Internet) - (Cable\ TV\ and\ Telephone) + (All\ Services)[/tex]
[tex]n(cable\ TV\ only) = 80\% - 25\% - 20\% + 15\%[/tex]
[tex]n(cable\ TV\ only) = 50\%[/tex]
The probability is:
[tex]P(Cable\ TV\ only) = \frac{n(Cable\ TV\ only)}{100\%}[/tex]
[tex]P(Cable\ TV\ only) = \frac{50\%}{100\%}[/tex]
[tex]P(Cable\ TV\ only) = 50\%[/tex]
Solving (b): P(Internet | cable TV).
This is calculated as:
[tex]P(Internet\ |\ cable\ TV) = \frac{Cable\ TV\ and\ Internet}{Cable\ TV}[/tex]
[tex]P(Internet\ |\ cable\ TV) = \frac{25\%}{80\%}[/tex]
[tex]P(Internet\ |\ cable\ TV) = \frac{25}{80}[/tex]
[tex]P(Internet\ |\ cable\ TV) = 31.25\%[/tex]
Solving (c): P(exactly 2 services).
This is calculated as:
[tex]P(exactly\ 2\ services) = (Cable\ TV\ and\ Internet - All) + (Cable\ TV\ and\ Telephone - All) + (Internet\ and\ Telephone - All)[/tex]
[tex]P(exactly\ 2\ services) = (25\% - 15\%) + (20\% - 15\%) + (23\%-15\%)[/tex]
[tex]P(exactly\ 2\ services) = (10\%) + (5\%) + (8\%)[/tex]
[tex]P(exactly\ 2\ services) = 23\%[/tex]
Solving (d): P(Internet and cable TV only).
This is calculated as:
[tex]P(Internet\ and\ cable\ TV \only) = \frac{(Internet\ and\ cable\ TV \only)}{100\%}[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = \frac{23\%}{100\%}[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = \frac{23\%}{1}[/tex]
[tex]P(Internet\ and\ cable\ TV \only) = 23\%[/tex]

Answer
Roundworm is 9ft long and the tapeworm is 60 feet long
Step-by-step explanation:
If we turn this into an algebraic equation we get 8x-3=69 with 8x being x + 7x because we know that the tape worm is about 7 times longer than the round worm and the roundworms length would be x here. We have the -3 because it is 3 minus 7 times the total length. We do this and eventually end up with x = 9 which is the length of the roundworm. We multiply that by 7 to get 63 and subtract 3 to get 60. If you want to check if this is right do 60+9 and you'll get 69 which is the total of them end to end. (also 69 funny haha)

At what rate does a payment plan for $1,500 accumulate $450 interest after 6 years?
Answer:
At a rate of 5%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
Payment plan for $1500 means that [tex]P = 1500[/tex]
$450 interest after 6 years means that [tex]E = 450, t = 6[/tex]
We have to find the rate I. So
[tex]E = P*I*t[/tex]
[tex]450 = 1500*I*6[/tex]
[tex]I = \frac{450}{1500*6}[/tex]
[tex]I = 0.05[/tex]
At a rate of 5%.

Answer:
B. 1.5 = 2p
Step-by-step explanation:
If p is the fraction of the price of a pizza, then 2p is the actual value of that fraction. We're told that is equal to the price of a hotdog, so ...
2p = 1.5
or
1.5 = 2p . . . . . . matches choice B
_____
Additional comment
Some of us would "cut to the chase" and compute the fraction directly:
p = (price of hotdog)/(price of pizza) = 1.5/2
No such choice is offered, so the next best is the equation you get when you multiply this by 2:
2p = 1.5
Armelia wants to paint three walls in her family room, wwo walls are 26 feet long by 9 feet wide. The other wall is 18 feet Hong by 9 feet wide. Each gallon of paint covers about 250 square feet. How many gallons of paint should Amella buy to paint the walls?
Answer: Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft
Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²
Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²
1 Gallon = 250 ft²
630 ft² ÷ 250 ft² per gallon = 2.52 gallons
