The chart below shows the distribution of weeds in a yard.A circle graph titled Lawn weeds. The largest proportion is crab grass, then dandelion, then clover, then chickweed.

A lawn-care specialist chooses a random sample from the yard and determines the number of weeds in the sample. The results of the sample are shown in the table below.

Weed Type
Number
Dandelion
2
Clover
3
Crab Grass
2
Chickweed
2

Which explains whether or not this is a representative sample?
Yes, this is a representative sample because each type of weed is represented in the sample.
Yes, this is a representative sample because each type of weed is represented approximately the same number of times in the sample.
No, this is not a representative sample because each type of weed should be represented in proportion to the number of weeds actually present in the yard.
No, this is not a representative sample because each type of weed should be represented exactly the same number of times in the sample.

The price of a calculator is 12.50 the sales tax is 7.5 How much will you pay for the calculator

Answers

Sales tax = 7.5%

7.5% of 12.50 = (7.5/100) * 12.5 = 0.075* 12.5 = 0.9375

tax = 0.9

Total pay = price + tax = 12.5 + 0.9375 = 13.4375

Total pay ≈ 13.44

Hope this solves it.

Final answer:

To calculate the total cost of a calculator with sales tax, you multiply the cost of the calculator by the sales tax percentage, and then add that amount to the original cost of the calculator. In this case, you'd pay $13.44 for the calculator.

Explanation:

The question asks how much you will pay for a calculator that costs $12.50 and has a sales tax of 7.5%. To answer this, we need to find out what 7.5% of $12.50 is, which is the amount of sales tax. Then, we add that tax to the original price of the calculator.

Step 1: Multiply $12.50 by 7.5/100 to get the tax amount: $12.50 * 0.075 = $0.94.

Step 2: Add this tax amount to the original price: $12.50 + $0.94 = $13.44.

So, you would pay $13.44 for the calculator with tax.

What's 7.8 divided by 15

Answers

The result will be 0.52

What is division?

The division is a process of splitting the amount into smaller and equal parts.

Rewrite 7.8 as 78/100 and divide it by 15.

$((78)/(10))/(15)=(78)/(10\cdot 15)\n\n=(39)/(5\cdot 15)\n\n=(39)/(75)$

Divide 39 by 75 using long division.

Thus, the quotient of the division is 0.52.

A Ferris wheel can accommodate 55 people in 25 minutes. How many people could ride the Ferris wheel in 3 hours. What was the rate per hour

Answers

The best way to find out how many people can be accommodated in 3 hours, is to convert this to minutes, and then divide by 25 (as this will show how many times it can be ridden in the three hour period). 3 hours is equal to 180 minutes. Therefore, 180/25 is equal to 7 (with a remainder of 5 minutes). As there can be 7 slots of 55 people, you have to multiply these together, and this gives you 385 people. You still have 5 minutes remaining, and the best way to do this is to find the highest common multiple of 55 and 25, which is 5, and divide both of these by 5. Meaning that in 5 minutes, there are 11 people. You then have to add this to 385, giving you 396.
In order to find the hourly rate, just multiply the 11 riders in 5 minutes by 12 (as there are 12 lots of 5 in 60), and this will give you 132 people.

396 people are able to ride the Ferris Wheel in three hours.
The rate of people per hour is 132.
Hope this helps :)
