Lettuce is planted on a 46-acre field. The field is divided into one-acre subplots. A sample is taken from each subplot to est

nalin [4]

The correct answer is B. Stratified sampling is used since the field is divided into subplots and a random sample is taken from each subplot.

Explanation:

Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.

A store that sells skis buys them from a manufacturer at a wholesale price of $63. The store’s markup rate is 50%. a. What price

Reptile [31]

a. The store charges $94.5 for the skis

b. 150% of the original price is the final price

Step-by-step explanation:

The given is:

A store that sells skis buys them from a manufacturer at a wholesale price of $63
The store’s markup rate is 50%

We need to find at what price the store charges its customers for the skis and

what percent of the original price is the final price

∵ The store buys the skis at $63

∴ The cost price of the skis = $63

∵ The store’s markup rate is 50%

- Find the amount of 50% of the cost price

∵ 50% of 63 = $\frac{50}{100}$ × 63 = 31.5

∴ the store's markup the cost of the skis by $31.5

- To find the selling price add 31.5 to the cost price

∴ The selling price of the skis = 63 + 31.5 = $94.5

a. The store charges $94.5 for the skis

To find what percent of the original price is the final price divide the final price by the original price then multiply the quotient by 100%

∵ 94.5 ÷ 63 = 1.5

∵ 1.5 × 100% = 150%

∴ The final price is 150% of the original price

b. 150% of the original price is the final price

Create a model to show that 2(2x+3y)=4x+6y

Tom [10]

You would first do 2 multiplied by 2x and that would give you 4x, then you would do 2 multiplied by 3y which would give you 6y, you would put 4x under 2x and put 6y under 3y and bring down your addition symbol
