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?
A. 0.15
B. 0.47
C. 0.69
D. 0.79
Answer:
0.69
Step-by-step explanation:
Here, we want to find the probability that a randomly selected television is connected to the internet given that it is voice-controlled
let P(V) is the probability of selecting a voice controlled television
P(I) is the probability that a selected television is connected to the internet
So the probability we want to calculate according to Baye’s theorem will be;
P(I|V) = P(I n V)/P(V)
P( I n V) = 22%
P(V) = 32%
So the probability is;
22%/32% = 0.6875 which is approximately 0.69
Answer: 0.69

Jackson has to have his car repaired. The mechanic tells him it will cost $75 for each hour of labor plus the cost of the parts. He discovers that the parts cost $165.
Part A: Write an equation that can be used to determine the cost of the repairs for any hours of labor.
Part B: How much would the repairs be if it took 3 hours?
Part C: What is the meaning of the slope in Part A?
Part D: What is the meaning of the y-intercept in Part A?
Answer:
a 75x+165=y
b 75(3)+165=390
c 75x is the cost increasing for each hour
d y-intercept=165, it cost at least 165 for the parts

write an equation in slope-intercept form for the line. slope=4,y-intercept=3
Answer:
y = 4x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 4 and c = 3, then
y = 4x + 3 ← equation of line

Hello!
[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]
[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]
Find the inverse by swapping the x and y variables:
[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]
Begin simplifying. Multiply both sides by 4y - 5:
[tex]x(4y - 5) = 2y + 2[/tex]
Start isolating for y by subtracting 2 from both sides:
[tex]x(4y - 5) -2 = 2y[/tex]
Distribute x:
[tex]4yx - 5x - 2 = 2y[/tex]
Move the term involving y (4yx) over to the other side:
[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]
Factor out y and divide:
[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]
Use this equation to evaluate [tex]f^{-1}(3)[/tex]
[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]

What is the average rate of change of the function
f(x) = 2x + 8
over the interval [2, 6)?
The average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.
Important information:
The function is [tex]f(x)=2x+8[/tex].The given interval is [2,6].Average rate of change:The average rate of change of the function f(x) over the given interval [tex][a,b][/tex] is:
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Using the above formula, we get
[tex]m=\dfrac{f(6)-f(2)}{6-2}[/tex]
[tex]m=\dfrac{(2(6)+8)-(2(2)+8)}{4}[/tex]
[tex]m=\dfrac{12+8-4-8}{4}[/tex]
[tex]m=\dfrac{8}{4}[/tex]
[tex]m=2[/tex]
Thus, the average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.

Two cities Asheville and Boulder are 2.5 inches apart on a map. A third city well spring is located exactly halfway between Asheville and Boulder. If the scale is 0.5 inches = 15 miles find the actual distance from wellspring to Boulder
Answer:
75miles
Step-by-step explanation:
Let A be the location of Asheville, B be the location of Boulder and W be the location of wellspring.
If well spring is located exactly halfway between Asheville and Boulder, then;
AW + WB = AB
If Asheville and Boulder are 2.5 inches apart on a map, then AB = 2.5 inches
The actual distance from wellspring to Boulder is WB
Since W is the midpoint of A and B, then AW = WB. The equation becomes;
WB + WB = AB
2WB = AB
WB = AB.2
WB = 2.5/2
WB = 1.25 inches
Hence the distance from wellspring to Boulder is 1.25inches.
Since 0.5 inches = 15 miles on the map,
1.25inches = x
Cross multiply;
0.5x = 15 * 1.25
0.5x = 18.75
x = 18.75/1.25
x = 75miles
Hence the actual distance from wellspring to Boulder is 75miles
