Answer:

The volume of candy that is needed by Polly is 1,437.3 cubic inches

Step-by-step explanation:

What we have to do here is to find the volume of the sphere with a diameter of 14 inches

If the diameter is 14 inches, then the radius is 14/2 = 7 inches

This is because the radius is half the measure of the diameter

To find the volume of the sphere, we use the formula below;

Volume of sphere

= 4/3 * pi * r^3

pi = 22/7

r = 7 inches

Volume is;

4/3 * 22/7 * 7^3

= 4/3 * 22 * 7^2 = 1437.3 cubic inches

In a school survey, three homerooms are chosen and 10 students from each homeroom are randomly chosen to complete the survey. Id

lesya [120]

Answer:

This sampling method used in this question is the stratified sampling method.

Step-by-step explanation:

There are about 5 known sampling methods.

- Random Sampling

In random sampling, each member of the population has an equal chance of being surveyed. All the students are given a number and random numbers are generated to pick the students to be surveyed.

- Systematic sampling

This is easier than random sampling. In systematic sampling, a particular number, n, is counted repeatedly and each of the nth student is picked to be sampled.

- Convenience Sampling

This is the worst sampling technique. It is also the easiest. In Convenience sampling, the surveyor just surveys the first set of students that they find.

- Cluster sampling

Cluster Sampling divides the population into groups which are called clusters or blocks. The clusters are selected randomly, and every element in the selected clusters is surveyed.

- Stratified Sampling

Stratified sampling divides the population into groups called strata. A sample is taken from all or some of these strata using either random, systematic, or convenience sampling. This is evidently the answer to the question as the students are divided into homerooms (strata) and samples are now randomly taken from 3 randomly selected strata.

The cost price of 18 sweaters is Rs425 per sweater and the total gain of the shopkeeper is Rs 6,750 1 find the sale price of eac

Nostrana [21]

Answer:

1. Sales price per sweater= Rs 800

2. percentage = 46.875% = 46.88%

Step-by-step explanation:

Given;

Cost price = Rs425 per sweater

Number of sweaters = 18

Total gain = Rs 6,750

Total cost price = cost price × number of sweaters

Total cost price = 18 × Rs425 = Rs 7,650

Total sales price = total gain + total cost price

Total sales price = Rs 6,750 + Rs 7,650

Total sales price = Rs 14,400

Sales price (per sweater) = Rs 14,400/18 = Rs 800 per sweater

Profit percentage = total gain/total sales price × 100%

Profit percentage = Rs 6,750/Rs 14,400 × 100%

Profit percentage = 46.875% = 46.88%
