Answer:

The sampling used is simple random sampling.

Step-by-step explanation:

Consider the provided information.

Types:

  1. Simple random sample is a subset of the population chosen from a larger set. Every person is selected by chance and randomly.
  2. Systematic sampling: list of elements is counted off.
  3. Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.
  4. Cluster sampling: divide the population into groups, usually geographically.
  5. Stratified sampling: divide population into groups called strata. but this time population might be separated into males and females.

Here, randomly selected 60 customers, Thus, the sampling used is simple random sampling.

wariber [46]

Answer: (1.5, 1.0)

Step-by-step explanation:

On coordinate plane , if we plot a point , we start from origin that is (0,0).

Direction for Empire State Building :  1.50 units to the right and 1 unit up to the origin .

By considering origin as the initial point, frim we move 1.45 units to the right on x-axis( positive) showed by red

Then move 1 unit up parallel to positive y axis showed by green.

So, the ordered pairs show the location of the Empire State Building = (1.5, 1.0)   [as both axis are positive in this region.]

So correct option = (1.5, 1.0)

Taylor opened a savings account with $425. After 2 years, the total interest earned was $10.20. What was the annual interest rat
storchak [24]

Answer:

R = 1.2%

Step-by-step explanation:

<u>Given the following data;</u>

Principal = 425

Time = 2

Simple interest = 10.20

To find the annual interest rate;

Mathematically, simple interest is calculated using this formula;

S.I = \frac {PRT}{100}

Where;

  • S.I is simple interest.
  • P is the principal.
  • R is the interest rate.
  • T is the time.

Substituting into the equation, we have;

10.20 = \frac {425*R*2}{100}

10.20 = \frac {850R}{100}

Cross-multiplying, we have;

1020 = 850R

R = \frac {1020}{850}

<em>R = 1.2%</em>

<em>Therefore, the annual interest rate is 1.2 percent. </em>

Solve the equation (linear equation)<br><br> <img src="https://tex.z-dn.net/?f=8%5E%7B2x%2B7%7D%20%3D%20%28%5Cfrac%7B1%7D%7B32%7
Minchanka [31]

Answer: x=-1

Step-by-step explanation:

By the negative exponent rule, you have that:

(\frac{1}{a})^n=a^{-n}

By the exponents properties, you know that:

(m^n)^l=m^{(nl)}

Therefore, you can rewrite the left side of the equation has following:

(\frac{1}{8})^{-(2x+7)}=(\frac{1}{32})^{3x}

 Descompose 32 and 8 into its prime factors:

32=2*2*2*2*2=2^5\\8=2*2*2=2^3

Rewrite:

(\frac{1}{2^3})^{-(2x+7)}=(\frac{1}{2^5})^{3x}

Then:

(\frac{1}{2})^{-3(2x+7)}=(\frac{1}{2})^{5(3x)}

As the base are equal, then:

-3(2x+7)=5(3x)

Solve for x:

-6x-21=15x\\-21=15x+6x\\-21=21x\\x=-1

There are 1,500 students in a school. 65% of them are girls. How many girls are there in the school?
Veronika [31]
First you have to multiply 1,500 by 65%.  A way to do that is 1,500 x 65 and then divide by 100.
So 1,500 x 65 is 97,500.
97,500 divided by 100 is 975.
The final answer is that there are 975 girls in the school.
