Which sampling method divides the population up into​ sections, randomly selects some of those​ sections, then chooses all the members from the selected sections to​ study?

What is Cluster Sampling?

Cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research. Researchers then select random groups with a simple random or systematic random sampling technique for data collection and data analysis.

So, The above mentioned type of sampling is called cluster sampling.

Cluster sampling is a sampling technique in which the entire population of interest is divide into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.

Lan pays a semiannual premium of ​$650 for automobile​ insurance, a monthly premium of ​$125 for health​ insurance, and an annua
bezimeni [28]

Answer:

Monthly Expense = $270.83

Step-by-step explanation:

The semi-annual premium is paid twice a year so,

Automobile insurance premium for whole year = 650*2

= $1300

Monthly premium will be paid 12 times a year so,

Health insurance premium for whole year = 125*12 = $1500

Annual premium is only paid once a year.

So adding all the premiums will give us the total premiums for whole year.

Total amount of premium for a year = $1300+$1500+$450

= $3250

The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.

So monthly expense is:

= 3250/12

= $270.83 ..

How much will it cost to print a circular sign with a radius of 1.5 feet if the printing company charges $29 per square foot? Us
RUDIKE [14]

Answer:

$204.89

Step-by-step explanation:

Step 1

We have to first find the area of the circular sign.

Since the sign is circular in shape, we use the Area of Circle.

Area of a Circle = πr²

r = 1.5 feet

π = 3.14

Area of a Circle = 3.14 × 1.5²

= 7.065ft² or 7.065 square feet.

Step 2

We find out how much it cost to print the circular sign.

We are told in the question that

The printing company charges $29 per square foot

Hence,

1 square foot = $29

7.065 square feet =

Cross multiply

= 7.065 × $29

=$ 204.885

Approximately to the nearest cent, $204.89

Therefore, it will cost $204.89 to print the circular sign

Sue saves $5 a week. The equation m=3.50w models the amount of money, m, Bill has saved after w weeks. At the end of 36 weeks, h
ch4aika [34]

Sue has saved $54 more than Bill

Step-by-step explanation:

Given

Sue saves $5 a week. so after 36 weeks he will have

= 36 * 5

= $180

Bill's saving is modeled by

m = 3.5w where w is the number of weeks

After 36 weeks,

m = 3.5 * 36\\=126

The difference between savings of Bill and Sue

= 180-126\\=54

Hence,

Sue has saved $54 more than Bill

Please help me write an equation for this polynomial graphed
oksian1 [2.3K]

The equation for this polynomial graphed will be P(x) = a(x + 2)(x + 1)(x – 3)³.

<h3>What is polynomial?</h3>

A polynomial expression is an algebraic expression with variables and coefficients.

The graph of the polynomial is given below.

From the graph, the roots of the polynomial will be -2, -1, and 3.

Then the factor of the polynomial will be

(x + 2), (x + 1), and (x – 3)

Then the polynomial will be

P(x) = a(x + 2)(x + 1)(x – 3)³

More about the polynomial link is given below.
