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.

(-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

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

Answer:

the third one

Answer: x=-20

-103= 6x + 17

-120=6x

-20=x

Here we have been clearly given with Principal, time period and rate of interest.

We have to calculate the simple Interest.

As we know that simple Interest is calculated by the formula :

Where,

Putting the values :

Step-by-step explanation:

Answer: 9/10 of the book.

Step-by-step explanation:

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

17/30+1/3=,17×3+1×30/30×3=51+30/90=,81/90

now let's try to simplify it.

81/90 by 9=9/10

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

Given :

The Johnson's went to dinner at the local family restaurant. The family meal totaled $45.29. The family left the waitress a standard 15% tip for good service.

To Find :

How much was the tip?

If Mr. Johnson just had dollars and quarters to leave for a tip, how many dollars and how many quarters should he leave as a tip?

Solution :

Amount of tip, A = $(45.29×0.15)

A = $6.79.

Number of dollar required is 6.

Number of quarter required is 3.

Hence, this is the required solution.

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]

[tex]\therefore[/tex] the consecutive numbers that sum up to [tex]15333[/tex] are [tex]5110, 5111,[/tex] and [tex]5112[/tex]

Hope this helps :)

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).

Complete Question

Which division problem does the model show? 3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third.

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

Hence:

Option a) 3 divided by one-third = 9 is the correct option.
