C. Setting up a booth in the lunchroom where students can give their thoughts

Step-by-step explanation:

Sampling is the process by which some part of the entire population is selected and researched. This selected population helps in estimating the researches for the entire population. There are various methods used for the process of sampling.

For the given case, the sampling method to be adopted is to view each students' opinion on the issue. For this process, setting up a booth can prove helpful as the opinion of every student can be viewed with no biases. Also, every student is free to provide their opinion with any fear.

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles

Answer:

-4.317

Step-by-step explanation:

The z test statistic for testing of 1-proportion can be computed as

[tex]z=\frac{phat-p}{\sqrt{\frac{pq}{n} } }[/tex]

We know that

phat=x/n.

We know that x=40 and n=120.

Thus,

phat=40/120=0.3333

p=hypothesized proportion=0.53

q=1-p=1-0.53=0.47

So, required z-statistic is

[tex]z=\frac{0.3333-0.53}{\sqrt{\frac{0.53(0.47)}{120} } }[/tex]

[tex]z=\frac{-0.1967}{ 0.04556 }[/tex]

z=-4.317.

Thus, the required test statistic value for given hypothesis is z=-4.317.

Answer:

Number of ways top 3 cars finish the​ race = 39,270

Step-by-step explanation:

Given:

Total number of cars = 35

Number of top cars = 3

Find:

Number of ways top 3 cars finish the​ race

Computation:

It is a permutation based problem.

So,

npr = n! / (n-r)!

35p3 = 35! / (35! - 3!)

35p3 = 35 ! / 32!

35p3 = 35 × 34 × 33

35p3 = 39,270

Number of ways top 3 cars finish the​ race = 39,270

Answer:

Third graph

Step-by-step explanation:

First, find the solution to the equation of inequality given.

2k + 8 < 5k - 1

Subtract 5k from both sides

2k + 8 - 5k < 5k - 1 - 5k

-3k + 8 < -1

Subtract 8 from both sides

-3k + 8 - 8 < -1 - 8

-3k < -9

Divide both sides by -3. (Note: < will change to > when dividing both sides with negative number)

[tex] \frac{-3k}{-3} [/tex] > [tex] \frac{-9}{-3} [/tex]

k > 3

The graph that will represent this solution will show that all values of k are greater than 3. 3 is not included as a solution. The "o" on top of the 3 on the number line won't be shaded to indicate that 3 is not included. And also, the arrow will point from 3 towards our right.

Therefore, the 3rd graph is the answer.

The angles don't need to be lined up vertically, or have one over top another. You could have them laid out horizontally. All that matters is that they are opposite angles after an X shape has been formed by two crossing lines. Vertical angles are always congruent.

Answer:

3.12732 × 10⁹ beats

Step-by-step explanation:

Given that, in 1 min, the heart of an individual makes 70 beats, the number of beats the heart of the healthy individual makes in 85 years can be calculated as follows:

1 yr = 365 days, therefore,

85yrs = 85*365 = 31,025 days

1 day = 24 hours

31,025 days = 31,025*24 = 744,600 hours.

1 hr = 60 mins

744,600 hours = 744,600*60 = 44,676,000 mins

This means the individual lived for 44,676,000 mins (85yrs)

If 70 beats are made in 1 min, therefore, in 85yrs, the individual will make:

44,676,000*70 = 3,127,320,000 beats = 3.12732 × 10⁹ beats in 85yrs

Answer:

4.0

Step-by-step explanation:

when rounded the nine adds to the whole number making it 4

Rounding 3.99408317124 to nearest tenth becomes 4.

We round numbers as it is easy to remember and also rounding a number to a certain place retains approximate value to that pace.

According to the given question we have to round  3.99408317124 to nearest tenth.

We know to round a number to a certain place we have to check the

digit that is one place lesser.

Now we have to round 3.99408317124 to tens place so we'll look at the digit at ones' place which is 9 and is greater than 5 so we'll add one to it this will make it 0  and 1 will carry over.

Thus the number becomes 4.0.

d). 1.04

Step-by-step explanation:

Average price of the ticket of a basketball game can be represented by the function,

p(x) = 0.03x² + 0.56x + 6.35

Where 'x' is the number of years or duration.

a). P(3) = 0.03(3)² + 0.56(3) + 6.35

           = 0.27 + 1.68 + 6.35

           = $8.30

b). P(13) = 0.03(13)² + 0.56(13) + 6.35

             = 5.07 + 7.28 + 6.35

             = $18.70

c). P(13) - P(3) = 18.70 - 8.30

                      = $10.40

d). [tex]\frac{P(13)-P(3)}{13-3}[/tex] = [tex]\frac{10.40}{10}[/tex]

Answer:

Step-by-step explanation:

Since the above sequence is a geometric sequence

For an nth term in a geometric sequence

[tex]A(n) = a ({r})^{n - 1} [/tex]

where

a is the first term

r is the common ratio

n is the number of terms

From the question

a = - 6

To find the common ratio divide the next term by the previous term

That's

r = 18/-6 = - 3 or -54/18 = - 3

Since we are finding the 12th term

n = 12

Substitute these values into the above formula

We have

[tex]A(12) = - 6 ({ - 3})^{12 - 1} [/tex]

[tex]A(12) = - 6 ({ - 3})^{11} [/tex]

The rounding off should be 1100.

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

Rounding numbers to the nearest hundred means we need to check the digit to the right of the hundreds place, that is, the tens place. For example, when 7456 is rounded to the nearest hundred, it becomes 7500.

Given numbers are 1143 and 1149.

According to the given numbers both the numbers rounded off nearest hundred.

The number 143 and 149 lies between 100 to 200.

So, the round off will be 100.

Step-by-step explanation:

Answer: 120 ways

Step-by-step explanation: The word ALGORITHM has 9 letters. We want them to be written in a row, which means, order of the letters are important, so, use Permutation.

Permutation is calculated by:

P(n,r) = [tex]\frac{n!}{(n-r)!}[/tex]

We want to use 6 of the 9 letters with first 3 being THM. So, n = 6 and r = 3:

Permutation will be:

P(6,3) = [tex]\frac{6!}{(6-3)!}[/tex]

P(6,3) = [tex]\frac{6.5.4.3!}{3!}[/tex]

P(6,3) = 120

There are 120 ways six letters of ALGORITHM be written in a row with first three letters THM.

Answer: [tex]y=\frac{ln(x)}{ln(10)}[/tex]

Step-by-step explanation:

To find the inverse of the function, you first replace the y with x and x with y. Then you solve for y.

[tex]y=10^x[/tex]                                [replace y with x and x with y]

[tex]x=10^y[/tex]                                [find natural log of both sides to get y alone]

[tex]ln(x)=ln(10)^y[/tex]                    [divide ln(10) on both sides]

[tex]\frac{ln(x)}{ln(10)} =y[/tex]                              

Now that we have found y after switching y with x and x with y, we know that the inverse is [tex]y=\frac{ln(x)}{ln(10)}[/tex].
