hat is the mean of the numbers given below? 2, 2, 8, 10, 15, 30, 36, 40, 50, 51 Report your answer in decimal form.​

Answers

Answer 1

Answer:

Mean = average or the sum of all numbers divided by how many numbers there are.

2 + 2 + 8 + 10 + 15 + 30 + 36 + 40 + 50 + 51 = 244

244/10 = 24.4

Answer 2

Answer:

24.4

Step-by-step explanation:

Add all numbers together To get 244

Then divide by the number of numbers given (10)

244÷10 = 24.4

Use a product of two binomials to find a polynomial that represents the area of Roberto's plot.

Answers

Answer:

First, we know that the area of a rectangle of width W and length L is:

A = W*L

In the case of Roberto's plan, we can see that the length of the whole rectangle is:

L = 1.5ft + x + 1.5ft = 3 ft + x

And the width is:

W = 3ft + x + 3ft = 6ft + x

Then the area of the whole thing is:

A = (3ft + x)*(6ft + x)

This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.

Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;

The total area of Roberto's borders is:

Area of the border =  (3ft + x)*(6ft + x) - x*x

                               =   3ft*6ft + 3ft*x + x*6ft + x^2 - x^2

                               = x*9ft + 18ft^2

Express the number of months in the year that are only 4 letters as a fraction in the simplest form, decimal rounded to the nearest thousandth and whole percent.

Answers

Answer:

There are only 2 months out of the 12 that have 4 letters in their name so it would be represented as 2/12, the numerator representing those 2 months and the numerator representing the 12 months in 1 year. 2/12 in its simplest form would be 1/6 because if you use the big one to simplify 2/12 and divided it by 2/2 you get 1/6. 1/6 as a decimal is 0.16 wich is 16% as a percent.

He sees the bus going a bit faster, so he thinks the bus is going at 20 km/h because to him, since he is also moving, it seems that the bus is only a little faster. Student 2 is on the sidewalk standing. He is not moving. When he sees the bus moving, the bus seems to be going fast because he is not moving. He estimates the speed of the bus to be 50 km/h.

The difference in estimates is due to their frames of reference.

Same side exterior angles sum to 180.

Using this axiom we can say that

150+ 3x = 180

Subtract 150 from both sides

3x = 30

Divide both sides by 3

Step-by-step explanation:

The multiplication of 10x 10 x 10 x 10 is 10000.

We have given that the

10x 10 x 10 x 10

We have to find the multiplication of the above 10.

What is multiplication?

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division.

here we have

10 x10=100

10x100=1000

10x1000=10000

Therefore the multiplication of 10x 10 x 10 x 10 is 10000.

The function is undefined for

Based on the domain, we would find the range by solving for

You can see that this is the case in the graph itself:
graph{(x + 7)/(x - 5) [-73.3, 74.9, -37.07, 36.97]}
What you should notice is the horizontal asymptote at

Because the function is trying to reach an undefined value at those points (

), you get these "walls" that cannot be crossed, only ascended or descended from either side.

The required domain of the function is all real numbers except -5 and 7. Option C is correct.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
Given function,
f(x) = (x + 6)  /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.

C. $17.250.00

D. $26,250.45

Answers

Answer:

p=$15000

R=15%

t=5years

compound amount CI=?

Step-by-step explanation:

we have

CI=p(1+R/100)^t=$15000(1+15/100)^5=$15000×1/15^5=$30170.35

The total amount of $15,000 at 15% compounded annually for 5 years will be $30,170.36 so option (B) is correct.

What is compound interest?

Compound interest is applicable when there will be a change in principle amount after the given time period.

The rate at which compound interest accrues depends on the frequency of compounding.

For instance, if you offer someone $500 at a rate of 10% annually, $500 will be considered your principal sum. After a year, the interest will be $50, making the principle amount $550. Moving forward, the interest will be $550 rather than $500.

Given

Principle amount = $15000

Rate of interest = 15%

The time period T = 5 years.

Compound interest formula

A = P  [tex][ 1 + R/100 ]^{T}[/tex]

A = 15000 [tex][ 1 + 15/100 ]^{5}[/tex]

A = $30,170.36 hence, the total amount after 5 year will be $30,170.36.
