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

The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 2007, and y represents number of new cases. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest hundredth. Using this equation, estimate the calendar year in which the number of new cases would reach 1344.

Graph a line that contains (-2,7) and a slope of 4
Answer:
The equation would be y = 4x + 15
Answer:
draw a line trogh the points (-2, 7) and ( -1,11)
Step-by-step explanation:
Plot the first point (-2,7) then go 4 up and 1 right (because the slope is
4 = 4 rise/1run ), plot that second point ( -2+1, 7+4) = (-1, 11), and connect them.
Josh was packing to move to another office. He packed 3 2/5 boxes on Tuesday and 2 9/10 boxes on Wednesday. After everything was moved to his new office on Wednesday afternoon, he only found 4 1/4 boxes. How many boxes were missing?
Answer:
2 1/10 boxes were missing.
Step-by-step explanation:
It is given that,
Josh packed [tex]3\dfrac{2}{5}[/tex] boxes on Tuesday
Josh packed [tex]2\dfrac{9}{10}[/tex] boxes on Wednesday
After everything was moved to his new office on Wednesday afternoon, he only found [tex]4\dfrac{1}{4}[/tex] boxes.
We need to find the no of boxes that are missing.
Total no of boxes packed on Tuesday and Wednesday,
[tex]3\dfrac{2}{5}+2\dfrac{9}{10}\\\\=\dfrac{17}{5}+\dfrac{29}{10}\\\\=\dfrac{63}{10}[/tex]
Missing boxes :
[tex]M=\dfrac{17}{4}-\dfrac{63}{10}\\\\=\dfrac{41}{20}\\\\=2\dfrac{1}{20}[/tex]
Hence, 2 1/10 boxes were missing.

Which of the following is the value of PQ?
A) 46
B) 61

D) 67
Answer:
d.67
Step-by-step explanation:
Answer:
B) 61Step-by-step explanation:
QR = QS
3x + 16 = 7x - 24
16 + 24 = 7x - 3x
40 = 4x
x = 40/4
x = 10
substitute x=10 into PQ = 2x+41
PQ = 2(10) + 41
PQ = 20 + 41
PQ = 61
12 + 3(8 + x)

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.

Answer:
D. -3z+2
Step-by-step explanation:
Steps:
Remove parentheses: (a) = a
= 5z+9-(8z+7)
....
Simplify
5z+9-8z-7: -3z+2
Answer:
-3z +2
Step-by-step explanation:
A expression in terms of z is given to us and we need to simplify out the given expression . The give an expression to us is ,
[tex]\implies (5z + 9 ) - ( 8z + 7 )[/tex]
Recall that , + × - = - . We have ,
[tex]\implies 5z + 9 - 8z - 7 [/tex]
Combining the like terms and simplifying ,
[tex]\implies 5z - 8z - 7 +9 \\\\\implies \underline{\underline{ -3z +2 }}[/tex]
Hence the last option is correct .
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
