Channel 9 is wondering if its viewers watch more live TV shows than taped TV shows. They selected all elderly viewers who watched last night's live TV show. Channel 9 conducting this interview would be an example of a _____.
Answer:
Channel 9 conducting this interview would be an example of a convenience sample.
Step-by-step explanation:
Convenience sampling is a kind of non-probability sampling (i.e. all items does not have an equivalent chance of being selected), which does not comprises of random collection of items.
Convenience sampling is where we take in items which are easy to reach.
For instance, gathering information on customer satisfaction by interviewing 6 randomly selected customers from a local store is an illustration of convenience sampling.
In this case Channel 9 selected a very easily available sample. Since, the elderly viewers are usually retired and can be reached easily either at home or on the phone, the sampling method used is convenience sample.

A line segment on a graph has endpoints of (-3,1) and (3,1). It is translated 5 units down
and then, reflected across the x-axis.
What are the endpoints after the series of transformations?
Answer:
(-3,4) (3,4)
Step-by-step explanation:
Down means you are dealing with the y value of the pair of points. It also means that you are going into negative territory.
(-3 ,1 -5) and (3, 1-5)
New point
(-3 , - 4) and (3,-4)
Now if you reflect this point across the x axis, you are still changing the y value. You will go from - 4 to + 4

Calculate simple interest : $125. 4 years, at 10% interest ..(how much is the interest alone?)
Here we have been clearly given with Principal, time period and rate of interest.
Principal (P) = $125Rate (R) = 10%Time (T) = 4 yearsWe have to calculate the simple Interest.
As we know that simple Interest is calculated by the formula :

S.I. is simple Interest R is rate of interest T is timePutting the values :

https://brainly.com/question/26734922What is an equation of the line that passes through the points (4, -2) and (8, – 7)?
Put your answer in fully reduced form.
Answer:
y= -5x/4 + 3
Step-by-step explanation:
To find slope, use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], so m(the slope) = (-7+2)/(8-4) = -5/4.
Now let us use (4,-2) in the equation [tex]y-y_1=m(x-x_1)[/tex].
So y - (-2) = (-5/4)(x - 4) (equation of the line)
y + 2 = -5/4(x - 4)
y + 2 = -5x/4 + 5
y= -5x/4 + 3 (slope-intercept form, also known as fully reduced form)
You could also use (8,-7) instead of (4,-2).

What 3 consecutive numbers if the sum is 15333
Answer:
[tex]5110, 5111, 5112[/tex]
Step-by-step explanation:
Let [tex]x=[/tex] first consecutive number
[tex]x + (x+1)+(x+2) = 15333[/tex] ([tex]x[/tex] is the first number, [tex]x+1[/tex] would be the second consecutive number of the sequence, and [tex]x+2[/tex] would be the third)
[tex]3x + 3 = 15333[/tex]
[tex]3x = 15330[/tex]
[tex]x = 5110[/tex]
[tex]x+1 = 5110+1[/tex]
[tex]= 5111[/tex]
[tex]x+2 = 5110 + 2[/tex]
[tex]= 5112[/tex]

1. Convert all of the fractions to have a common denominator. 6, 5, and 3 are all multiples of 30, so we can convert the fractions to 30ths.
1/6 = 5/30
2/5 = 12/30
1/3 = 10/30
2. Add the fractions together to find the whole amount of the book Joyce has read.
5/30 + 12/30 + 10/30 = 27/30
3. Simplify
27/30 -> 9/10
Step-by-step explanation:
1/6 + 2/5 +1/3=
nominator × with the other fraction denominator+ second fraction nominator × with first denominator / denominator ×denominator =
1/6+2/5= 1×5+2×6/6×5=5+12/30=17/30

The graph for the equation y = 2 x minus 2 is shown below. On a coordinate plane, a line goes through points (0, negative 2) and (1, 0). If another equation is graphed so that the system has one solution, which equation could that be? y = 2 (x + 1) y = 2 (x minus 1) y = 2 (x minus 2) y = negative 2 (x + 1)
THIS IS TIMED
Answer:
i think it is b correct me if i am rong
Step-by-step explanation:
The correct equation for the solution to be one will be y = 2(x -1) hence, the correct option is (B).
What is a graph?The link between lines and points is described by a graph, which is a diagrammatic representation of a network. A graph is made up of some points and the distance between two. It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.
For example to draw the equation y = 2x +9 this will draw a straight line in the coordinate geometry.
Given that an equation y = 2x - 2 now another equation draw which should intersect with the line y = 2x - 2 at a single point only so that the system has only one solution.
so the y = 2x - 2 should be matched with any one option.
By cross-checking the option it will be (B) with equation y = 2(x -1).

a) 3 divided by one-third = 9
b)3 divided by two-thirds = 9
c) 9 divided by one-third = 3
d) 9 divided by two-thirds = 3
Answer:
a) 3 divided by one-third = 9
Step-by-step explanation:
We are told in the question that:
3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third.
The division problem does the model shows from the description above is calculated as:
3 fraction bars ÷ 1/3
= 3 ÷ 1/3
= 3 × 3
= 9

Emma is 10 years old. She asked her father how old he was. Her father answered: "When you will be my age, I will be 70." How old is Emma's father?
Answer:
Emmas father would be 40 years old
Step-by-step explanation:
if the father is 40 years old right now emma will be his age in 30 years.
in 30 years emma will be as old as he was when she was ten (10+30=40)
after the 30 years emmas father who was once 40 years when she asked how old he was would be 70 years old (30+40=70)
He is 40 years old.
Equation: (f+e)/2 = father's age. Here f=70 and e=10.
So, (70+10)/2 = 80/2 = 40.
Solution can be wrong. But answer is right. Answer is definitely 40 years old

The price of Stock A at 9 A.M. Was $12.53. Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $13.28. It begins to decrease at the rate of $0.09 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
1.8571428 hours
Step-by-step explanation:
Given that :
Price of stock A at 9 am = $12.53
Rate of increase = $0.12 per hour
Price of stock B at noon = $13.28
Rate of Decrease = $0.09 per hour
Let number of hours = x
Price of stock A at noon :12.53 + 0.12(3) = 12.89
12.89 + 0.12x = 13.28 - 0.09x
0.12x + 0.09x = 13.28 - 12.89
0.21x = 0.39
x = 0.39 / 0.21
x = 1.8571428
Hence the prices of the stock will be the at about 1.857 hours
