A sample survey is a survey that is done by taking a sample of people or items that represent a larger population.

An observational study is a type of study whereby a researcher utilizes observed information to gain more information about a group of individuals.

An experiment is where a researcher purposely applies different treatments to different groups and then does a comparison of  the groups to determine if there is any difference in a specific variable of interest.

The amount Vicente needs to deposit now in order to have a balance of $20,000 in his savings account after 10 years is $15,384.62

What is simple interest?

The simple interest on the savings is determined as the deposit multiplied by the annual interest rate and the number of years that deposit would last in the account

I=PRT

I=simple interest

P=principal=deposit=unknown

R=annual simple interest=3%

T=number of years=10

A(amount in 10 years)=P+PRT

The number of miles that John Smith can travel with his budget if he has ​$500 left in his budget for car rental expenses is 900 miles.

Amount left in the budget = $500

Since he will rent a car that costs $50 per day and $ 0.50per mile, the expression will be:

50 + 0.50m = 500

where m  = number of miles

Collect like terms

0.5m = 500 - 50

0.5m = 450

Divide

m = 450/0.5

m = 900

Therefore, the number of miles that John Smith can travel with his budget is 900 miles.

The number of months so that the investment gets double will be 86 months.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on. The amount is given as,

A = P + (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

The principal amount is $450 and if the amount gets doubled, then the value of the amount will be $900. The simple interest rate is 14%. Then the time is given as,

A = P + (PRT)/100

900 = 450 + [450 x 14 x T] / 100

450 = 450 x 14 x T / 100

T = 100 / 14

T = 7.14 years

T = 7.14 x 12

T = 85.7 ≈ 86 months

The number of months so that the investment gets double will be 86 months.

The original price of the car is $15,000

Let us assume the original price of car be x. So, forming the equation to find the value of x and hence the original price of the car.

Equation -

x - 20% × x = 12000

x - 20/100×x = 12000

Cancelling zero as common in both numerator and denominator, on the left hand side of the equation

x - x/5 = 12000

Taking LCM on Left Hand Side of the equation

(5x - x)/5 = 12000

Rewriting the equation

4x = 12000 × 5

Performing multiplication on Right Hand Side of the equation

4x = 60,000

x = 60,000 ÷ 4

Performing division

x = 15,000

Therefore, the original price of the car is $15,000.

The rotation of the vertices L(2,-2), M(7,-3), and N(5,2) are L'(-2, -2), M'(-7, -3), and N'(5, 2) respectively.

Let the point be having coordinates (x,y).

If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

We know that the rotation of a point (x,y) about the origin by 90° is (-y,x).

Given vertices of ΔLMN are  L(2,-2), M(7,-3), and N(5,2).

Let consider the rotations of L, M, and N are L', M', and N' respectively.

The rotation of a point L(2,-2)  about the origin by 90° is L'(-2,-2).

The rotation of a point M(7,-3) about the origin by 90° is M'(-7,-3).

The rotation of a point N(5,2) about the origin by 90° is N'(5,2).

Hence, the points  L'(-2, -2), M'(-7, -3), and N'(5, 2) are the rotation of vertices.

Therefore, L, M, and N of ΔLMN about the origin by 90°.

Considering the definition of combination,  if a family has 5 children, in 10 ways the parents can have 2 boys and 3 girls as children.

Combinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.

To calculate the number of combinations, the following expression is applied:

[tex]mCn=\frac{m!}{n!(m-n)!}[/tex]

where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.

If a family has 5 children, you can know that:

So, you can observe that 5C3 is equal to 5C2. Then:

The following statement are true:

It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.

Using the formula

time for doubling money= 72/R

So, 72/12 = 6 years

Thus, It will take 6 years to double the investment. This statement is true.

So, 72/18 = 4 years

Thus, It will take 4 years to double the investment. This statement is not true.

so, 72/8= 9 years.

Thus, It will take 9 years to double the investment. This statement is true.

So, interest = PRT/100

I  = (2000 × 0.05 × 20)

I = $2000

Thus, This statement is true.

Interest = ( 700 × 0.06 × 12 ) = $504

Step-by-step explanation:

first you have to find x so that you can find each angle

the interior angles of a triangle is equal to 360

add the angles together x+x+7+x+11=360

combine like terms 3x+18=360

subtract 18 on both sides 3x=342

divide by 3 on both sides x=114

to find angles:

plug in X to each side

(114)+7 = angle C

(114)+11= angle A

The value of the composite function f(g(x)) is calculated as f(g(x)) = 65.

Composite functions is one in which one function is placed within another.

For, the given values in the question;

f(x) = 9x+2 and g(x) = x-2

We have to find the value of f(g(x)) for x = 9.

First estimate the value of g(x) by substituting  x = 9 in it.

g(x) = x-2

g(9) = 9-2 = 7

Now,

f(x) = 9x+2 and

f(g(x)) = f(7) = 9x+2, (substitute x = 7)

f(g(x)) = 9×7 + 2

f(g(x)) = 65.

Thus, the value of the composite function f(g(x))  = 65.

Step-by-step explanation:

The times associated with each speed are:

It is always true that the speed is inversely proportional to time.

In this case we find the situation of bicycle moving at constant speed, where the traveled distance (s), in miles, is equal to the following expression:

s = v · t           (1)

Where:

Now we proceed to calculate time needed for each speed:

t = s / v

Case 1

t = 100 mi / 5 mi / h

t = 20 h

Case 2

t = 100 mi / 10 mi / h

t = 10 h

Case 3

t = 100 mi / 15 mi / h

t = 6.667 h

Case 4

t = 100 mi / 20 mi / h

t = 5 h

t = 100 mi / 25 mi / h

4 is the maximum number of days.

Using Inequality, the maximum number of days that Lily can rent the car while staying within her budget is 4 days.

The rental car company charges $71.02 per day to rent a car and $0.12 for every mile driven.

Lily wants to rent a car and she plans to drive 475 miles. She has a budget of $390.

Therefore, the maximum number of days that Lily can rent the car while staying within her budget can be calculated as follows:

Using inequality,

total cost = 71.02(x) + 0.12(y)

where

x = number of days

y = number of miles

Therefore,

71.02x + 0.12(475) ≤ 390

71.02x ≤ 390 - 57

71.02x ≤ 333

x ≤ 333 / 71.02
