A recent survey suggests that 47% of all televisions are connected to the internet, 32% are voice controlled, and 22% are both connected to the internet and voice controlled. Suppose a television is selected at random and it is voice controlled. What is the probability that a randomly selected voice-controlled television is also connected to the internet?
0.15
0.47
0.69
0.79
The probability that a randomly selected voice-controlled television is also connected to the internet is 0.69.
Option C is correct.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
let P(V) is the probability of selecting a voice controlled television
and, P(I) is the probability that a selected television is connected to the internet.
So, the probability that a randomly selected voice-controlled television is also connected to the internet
P(I|V) = P(I ∩ V)/P(V)
P( I ∩ V) = 22%
P(V) = 32%
So, P(I|V) = 22%/32% = 0.6875

f(x) = 2x and g(x) = x + 1, find f(3) and find gf(3)
Answer:
6 and 7
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x) , that is
f(3) = 2(3) = 6
To evaluate g(f(3)), substitute f(3) = 6 into g(x)
g(6) = 6 + 1 = 7

4, 9, 16, 25, 36, 49, 64, 81, 100, 121
a negative times a negative is a positive and squaring those numbers would be multiplying a negative by itself.
For example (-2)*(-2) is 4
**note, this only applies if the negative value is in the parentheses. (-2)^2 is different than -2^2 because with -2^2 only the 2 is getting squared and then you’d have to multiply the negative after**

-2 -2^3 = -2 • -2 • -2 = -8
-3 -3^3 = -3 • -3 • -3 = -27
-4 -4^3 = -4 • -4 • -4 = -64
-5 -5^3 = -5 • -5 • -5 = -125
-6 -6^3 = -6 • -6 • -6 = -216

Hey there!
So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.
The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.
Remember:
A complementary angle is made of up TWO angles that add up to 90 degrees.
A supplementary angle is made up of TWO angles that add up to 180 degrees.
I hope this helped!!!

One side of a square room measures 24 ft. How many square yards of carpet are necessary to carpet the room? Hint: 1 yd2 = 9 ft2.
yd2
Answer:
64 square yards
Step-by-step explanation:
If the room is a square, then all sides of the room should be equal. To find the area of the room, we would need to multiply 2 adjacent sides of the room, meaning 24 x 24 = 576. Since we need yards of carpet, not feet, and we know that 1 square yard is 9 square feet, we divide our total area in feet by 9. This gives us 64sq yards of carpet

Frank invests $1,000 in simple interest investment account that pays 8% a year. After a number of years, he withdraws his balance of $2,200. Using the formula I = P r t, how many years was his money invested? Work backwards-but find the Interest first!
Answer:
15 years
Step-by-step explanation:
Given data
P=$1,000
R=8%
A= $2200
I= A-P
I=2200-1000
I=$1200
Applying the formula
I=PRT/100
1200=1000*8*T/100
cross multiply
1200*100= 8000T
120000= 8000T
divide both sides by 8000
T=120000/8000
T=15 years
Hence the time is 15 years
