Answers

Answer:

go to a skatepark

Step-by-step explanation:

Answer:

Thus, conducting the survey so that the sample is biased toward overturning the ban is to increase the number of people not favoring the skateboarding ban in comparison to people who are favoring the ban.

Step-by-step explanation:

Given:

A survey regarding the decision on banning skateboarding

To find:

how the poll may be conducted in such a way that the sample is skewed in favor of reversing the prohibition

Explanation:

A reasonable sample is
● selected at random,
● representative of the population, and
● large enough to provide accurate data.

While taking the sample, the number of people who are not favoring the ban on skateboarding should be increased in comparison to the number of people who are in favor of the ban. Doing so will result in a biased sample indicating that majoring of people do not want to ban skateboarding as the sample is projecting a majority who are against the ban instead of favor the ban.

8.37 Sale prices at the Ajax Outlet Store are 50% below original prices. On Saturdays, an additional discount of 20% off the sale price is given. What is the Saturday price of a coat whose original price is $180?

Answers

Answer:

Given:

Sale prices at the Ajax Outlet Store are 50% below the original prices. On Saturdays, an additional discount of 20% off the sale price is given.

To find:

The Saturday price of a coat whose original price is $180.

The formula used to calculate the percentage is (value/total value)*100%.

Step-by-step explanation:

Step 1 of 2

The original price of coat = $180



Ajax always sells at 50% discount

So their sale price = $90

Step 2 of 2

On Saturdays they sell 20% less

Which implies-

1/5*90 = 18

90-18=72

They sell at $72 on Saturday.

180*50=9000
9000/100=90
90*20=1800
1800/100=18
90-18=72
The Saturday sale price of the coat would be $72.

The sign of f on the interval -7/3 < x < -3/5 is always positive.

How to solve for the sign on the interval

We have the equation

(5x+3)(x−2)(3x+7)(x+5) > 0

Now when f(x) > 0

Then -7/3 < x < -3/5

This would tell us that the sign would become positive when it changes from the less than to greater than sign

8.3.4 Karl bought five folders from Pay-A-Lot at a cost of $2.50 each. Pay-A-Lot had a 20% -off sale the following day. How much could Karl have saved on the purchase by waiting a day?

Answers

Answer:

Karl could have saved $2.50

Step-by-step explanation:

Cost of folders without the sale: 2.5*5 = $12.50

Cost of folders with the sale: 0.8*2.5 = $2 per folder * 5 folders = $10.00

Difference between prices: 12.5-10 = $2.50

Answer:

2.50$ Karl could have saved on the purchase by waiting a day.

Step-by-step explanation:

Given: total number of folders Karl bought is 5 .

The cost of each folder is 2.50$.

20% off sale the following day at Pay-A-Lot.

we have to find the 20% of each folder and then add them to get the final saving of Karl if he had waited for a day.

Step 1 of 2

20% of 2.50$ is equal to

[tex]$$\begin{aligned}&=2.50 \cdot 20 \% \\&=2.50 \cdot \frac{20}{100} \\&=0.50 \$\end{aligned}$$[/tex]

this is the amount Karl would save on each folder if waited for a day or this is the discount on the amount of 2.50$ that the shopkeeper will give the next day on each

Step 2 of 2

Karl bought 5 folders

so, total savings would be equal to

[tex]$$\begin{aligned}&=5 \cdot 0.50 \\&=2.50 \$\end{aligned}$$[/tex]

7.6.3. A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo. For every 12 -foot leap of the kangaroo, the rabbit makes a 7 -foot leap. How many leaps will the kangaroo have to make to catch up to the rabbit if the two animals always leap at the same time?

Answers

Answer:

The number of leaps will the kangaroo have to make to catch up to the rabbit if the two animals always leap at the same time is 30 times.

Step-by-step explanation:

Given:

A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo.

For every 12 -foot leap of the kangaroo, the rabbit makes a 7 -foot leap.

Find:

the number of leaps will the kangaroo have to make to catch up to the rabbit if the two animals always leap at the same time

Step 1 of 1

The kangaroo gains 5 feet on every leap.

The kangaroo must gain 150 feet total,

so it must jump [tex]\frac{150}{5}=30$[/tex] times to catch the rabbit.

Kangaroo needs 30 leaps to make to catch up to the rabbit if the two animals always leap at the same time.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo.

For every 12 -foot leap of the kangaroo,

the rabbit makes a 7 -foot leap.

Let n be the number of leaps.

According to the question:

We have the equation.

To solve for x;

12x = 7x + 150

12x - 7x = 150

5x = 150

x = 150/5

x = 30

Therefore, the Kangaroo needs 30 leaps to catch the rabbit.

8.42 Three bags of jelly beans contain 26,28 , and 30 beans. In each bag, the percent of the beans that are yellow is 50%, 25%, and 20%, respectively. All three bags of candy are dumped into one bowl. What percent of the beans in the bowl are yellow? Round your answer to the nearest integer.

Answers

Answer:

Step-by-step explanation:

Figure out the number of yellow beans in each bag:

Bag A: 0.5*26 = 13 beans

Bag B: 0.25*28 = 7 beans

Bag C: 0.2*30 = 6 beans

The total number of beans in the bowl: 26+28+30 = 84

Total number of yellow beans: 13+7+6 = 26

Percentage of yellow beans: 26/84 *100 = 30.9523

Rounded answer: 31%

Answer:

The percentage of yellow beans in the bowl of 84 is approximately 31%.

Step-by-step explanation:

We are given with a word problemWe are asked to find the total percentage of yellow jelly beans We can do this two steps

         Step 1: Finding the number of yellows beans in each bags

         Step 2: Finding the total percentage of yellow beans

Step 1 of 2

We are given that the three bags contain 26,28 and 30 beans totally in which the percent of yellow beans are 50%, 25% and 20% respectively.

We have to find the number of yellow beans in each bag.

[tex]$=\frac{50}{100} \times 26$$[/tex]

The number of yellow beans in first bag

[tex]$$\begin{aligned}&\frac{1}{2} \times 26=13 \\&=\frac{25}{100} \times 28\end{aligned}$$[/tex]

The number of yellow beans in second bag

[tex]$$\begin{aligned}&\frac{1}{4} \times 28=7 \\&=\frac{20}{100} \times 30 \\&\frac{1}{5} \times 30=6\end{aligned}$$[/tex]

The number of yellow beans in third bag

Step 2 of 2

From the first step we got the number of yellow beans in each bags.

The total number of yellow beans in the bowl =13+7+6

The total number of beans in the bowl

[tex]$$\begin{aligned}=26 &+28+30 \\=& 84 \\&=\frac{26}{84} \times 100\end{aligned}$$[/tex]

The percentage of yellow bean in the bowl

On a snowy day 85% of the students of Wilson high school were present. If 572 of the students were present, how many students were enrolled at the school?

Answers

Answer:

673

Step-by-step explanation:

okay so uh this is my way and the answer works so like yea teachers dont show like this but ii figured this works

okay so

85/100 = 572/?

so if you divide 85 by 85 its gonna equal 1 and 1 times 100 is gonna be 100

useing the same concept, it should be the same with 572 , but instead of divideing by 572, divide by 85.

basically 572/85

okay now thats gonna give you 6.72941176471 thats vasically 1% of the population.

so multiply 6.72941176471 * 100

so now you have

672.941176471 and you can round this to 673 kids.

and you know its right since 85% of 673 is 572.05 and you can sound to 572

Answer:

673 students

Step-by-step explanation:

Divide the number of students who applied and the decimal of the percentage they represent.

Hint: Assign a variable.

Answers

Answer:

The total number of games won by Unicorn is 40.

Step-by-step explanation:

We are given with a word problemWe are asked to find the number of unicorns played during the seasonWe can do this in two steps

         Step 1: Finding the win percentage

         Step 2: Finding the number of unicorns played during the season

Step 1 of 2

Let the number of games played by unicorn be x.The unicorn won 60% of the first x-10 games That is [tex]$\frac{60}{100} \times(x-10)$[/tex]

Combining the 8 games we get,

[tex]$$\begin{gathered}\frac{60}{100}(x-10)+8=\frac{60}{100} \times x-\frac{60}{100} \times 10+8 \\0.6 x-6+8=0.6 x+2\end{gathered}$$[/tex]

Step 2 of 2

The unicorn totally won 65% of the games played.

That is [tex]$\frac{65}{100} \times x=0.65 x$[/tex]

Equating both the equation gives

[tex]$$\begin{gathered}0.6 x+2=0.65 x \\2=0.65 x-0.6 x \\2=0.05 x \\\frac{2}{0.05}=x \\40=x\end{gathered}$$[/tex]
