School newspaper staff went to three different sports games to survey students on their favorite sport, and the results are shown in the table below. Are these samples biased? Why or why not?

Favorite Sport Survey
Sample 1
Sample 2
Sample 3
Basketball 23 Basketball 1 Basketball 1
Football 2 Football 24 Football 2
Volleyball 0 Volleyball 0 Volleyball 22
These samples are not biased because students like different sports and the samples reflect the different opinions.
These samples are biased because the newspaper staff went to a basketball game, football game, and volleyball match to interview the students.
These samples are not biased because each has a total of 25 students, which makes them equal.
These samples are biased because 0 should never appear in a sample as it is not possible.

Answer:

Supplimentry

Step-by-step explanation:

The situation can be modeled by a geometric sequence with an initial term of 284. The student population will be 104% of the prior year, so the common ratio is 1.04.

Let \displaystyle PP be the student population and \displaystyle nn be the number of years after 2013. Using the explicit formula for a geometric sequence we get

{P}_{n} =284\cdot {1.04}^{n}P

n

=284⋅1.04

n

We can find the number of years since 2013 by subtracting.

\displaystyle 2020 - 2013=72020−2013=7

We are looking for the population after 7 years. We can substitute 7 for \displaystyle nn to estimate the population in 2020.

\displaystyle {P}_{7}=284\cdot {1.04}^{7}\approx 374P

7

=284⋅1.04

7

≈374

The student population will be about 374 in 2020.

Step-by-step explanation:

1) 5/10

2) 9/12

3) 4/16

4) 2/6

Answer:

A

Step-by-step explanation:

Hey There!

So the first thing that we want to do is find the formula for volume of a pyramid

[tex]V=\frac{lwh}{3}[/tex]

l = length

w = width

h = height this is a square pyramid so if the length is 8 then the width is 8

So all we have to do now knowing the formula is plug in the values

[tex]V=\frac{8*8*9}{3} \\8*8=64\\V=\frac{64*9}{3} \\64*9=576\\V=\frac{576}{3} \\\frac{576}{3} =192\\[/tex]

So we can conclude that the volume of the square pyramid is 192

hope this helps :)

Answer:

198

Step-by-step explanation:

V= a^2 h/3 = 8^2 x 9/3 = 192

Or

Volume = The base edge squared multiplied by the height divided by three. Which would convert to-

Volume = 8^2 x 9/3 = 192

Answer:

3/4

Step-by-step explanation:

If 2 out of 8 of the kittens are white, than 6 aren't white. That fraction would be 6/8 but when you simplify you get 3/4.

The answer is 3/4 of the kittens are not white.

This a simplifed version of 6/8 which is the complement of 2/8, the amount of white kittens.

Answer:

A

Step-by-step explanation:

a translation 16 units to the left will replace x with x+16, and a translation 6 units down will replace g(x) with g(x)-6, so it's A.

Answer:

A -  (2a+0)/2 ; (2b+0)/2  = ( a , b )

B -  (-2a+0)/2 ; (2b+0)/2  = ( - a, b )

C - (-2a+0)/2 ; ( -2b+0)/2  = ( - a, - b )

D - (2 a+0)/2 ; (-2b+0)/2  = ( a , - b )

Step-by-step explanation:

Answer:

There are 12 sections on the spinner, and out of the 12 sections, 5 of them are red.

If he spins the spinner 48 times, he should expect 5x4, or 20 of the spins to land on red.

Answer:

Rate = 10%

Step-by-step explanation:

Given:

Amount deposit = 25,000

Amount get = 26,250

Time = 6 month = 6 / 12 = 0.5 year

Find:

Rate

Computation:

Interest = Amount get - Amount deposit

Interest = 26,250 - 25,000

Interest = 1,250

Interest = P x R% x T

1,250 = 25,000 x R% x 0.5

Rate = 10%

Step-by-step explanation:

Answer:x=−y−1

Step-by-step explanation:Let's solve for x.

−y=x+1

Step 1: Flip the equation.

x+1=−y

Step 2: Add -1 to both sides.

x+1+−1=−y+−1

x=−y−1

Answer:

x=−y−1

Given:

The figure of a trapezoid.

Length of mid-segment = 5.5

Height of the trapezoid = [tex]6\sqrt{3}[/tex]

To find:

The area of the trapezoid.

Solution:

The area of a trapezoid is:

[tex]A=M\times h[/tex]       ...(i)

[tex]A=\dfrac{a+b}{2}\times h[/tex]

Where, a,b are bases and h is the vertical height.

We know that [tex]M=\dfrac{a+b}{2}[/tex] is the length of the mid-segment.

Putting M=5.5 and [tex]h=6\sqrt{3}[/tex] in (i), we get

[tex]A=5.5\times 6\sqrt{3}[/tex]

[tex]A=33\sqrt{3}[/tex]

Therefore, the area of the trapezoid is [tex]33\sqrt{3}[/tex] units squared.

Answer: The eccentricity of the conic section shown in the given picture = 0

Step-by-step explanation:

The eccentricity of a conic is measure to determine how un-circle a conic section.

In the given picture, we have a circle.

A circle has an eccentricity of zero.

Therefore, the eccentricity of the conic section shown in the given picture = 0

Answer:

[tex]Selling\ Price = 1.5m[/tex]

Step-by-step explanation:

Given

[tex]Market\ Price = m[/tex]

[tex]Discount = 50\%[/tex]

Selling Price = 3 * Amount she paid

Required

Determine the selling price

If she gets a discount of 50%, then she pays 50% (i.e. 100 - 50%).

So, the amount she paid is:

[tex]Amount = 50\% * Market\ Price[/tex]

[tex]Amount = 50\% * m[/tex]

[tex]Amount = 0.5* m[/tex]

[tex]Amount = 0.5m[/tex]

She sells at three times that amount.

So, the selling price is:

[tex]Selling\ Price = 3 * 0.5m[/tex]

[tex]Selling\ Price = 1.5m[/tex]

Answer:

28 learners

Step-by-step explanation:

Boys : Girls

3 : 4

Since there are 12 boys and 3 units of them...

3 units = 12

1 unit = 12 ÷ 3 = 4

Girls =

4 units = 4 x 4 = 16

Total number of girls and boys: 12 + 16 = 28

Answer:

Answer:

3 hours + 5hours = 8 hours ÷ 2 =

4 hours is your answer.

Step-by-step explanation:

If you have 2 people working and need to know how long it would take them to finish a job. Working together on the same job, you add each of their total hours to do the job alone,, 5 + 3 = 8, then divide the 8 by 2 people

equals 4 hours for 2 people on 1 job.
