Can a table with same input and output be a function like in the picture:

In order to calculate the area of carpet needed to cover the entire floor, we just need to calculate the area of the room.

The area of a rectagle is calculated by the product of its dimensions, so we have:

So the area of carpet needed is 132 square feet.

The arrows indicate that the graph of the function continues beyond what can be seen in the image.

Notice that the graph does not appear to have asymptotes; then, the domain of the function is:

And the range is:

Since the graph seems to continue towards the +y-direction and the -y-direction

Finally, notice that for each value of x, the graph has only one value of y. This is the key characteristic of a function; the graph is a function.

No solution

y = 4x + 5

y = 4x - 2

Solving algebraically:

equate both equations

y = y

4x + 5 = 4x - 2

collect like terms:

4x - 4x = - 2 - 5

0 = -7

When the right hand side is not the same as the left hand side equation, it is a no solution.

Their intersection point gives no solution

Answer:

0.26599

Step-by-step explanation:

We will assume a normal distribution for the salaries

We have the following information

Mean μ = 64000

Standard deviation σ = 6400

And we are asked to find P(X < 60000)

First find the z score corresponding to X = 60000

The z score is given by (X - μ) / σ

z score for 60000 with μ = 64000 and σ = 6400 is

z = (60000 - 64000)/6400
z = -40000/6400 = -0.625

We can either look up the P value from the z-tables or simply use a calculator

P(X < 60000)  and this works out to 0.26599

Side of cube = 8 ft

Volume of cube = Side x Side x Side

Volume of cube = 8 x 8 x 8

Volume of cube = 512 feet^3

A cylinder with diameter 8feet is cute form the cube

Height of cylinder = Side of cube

Height of cylinder = 8 feet

Diameter of cylinder = 8 feet

Radius of cylinder = 4feet

The volume of resulting shape = Volume of cube - Volume of cylinder

Volume of resulting shape = 512 - 401.92

Volume of resulting shape = 110.08 ft^3

The quotient of 7.7 x 10^8 and 5.5 x 10^2 expressed in scientific notation is 1.4x10^6.

What is quotient?

A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is used to describe the integer component of a division (when Euclidean division), as well as a fraction or a ratio (when proper division). A quotient in the second sense is only the proportion of a dividend to its divisor.

Lets calculate the quotient for the value given in question:

[tex]7.7 \times 10^8[/tex]

[tex]5.5 \times 10^2[/tex]

Now we divide the 7.7 by 5.5

[tex]\frac{7.7}{5.5} = 1.4[/tex]

we get value 1.4.

on dividing  [tex]\frac{10^8}{10^2}[/tex] we get, [tex]10^6[/tex]

Combining both the value, we get

quotient = [tex]1.4 \times 10^6[/tex]

Following the instructions provided, we shall use a graphing calculator (Desmos) to determine the equation of the circle shown by the "colorful people."

The first step is to determine the radius which we can observe from the circle itself, whose diameter spans from 0 units to 10 units along the x-axis. The radius therefore is 5 units (half of the diameter).

Observe also that the center has now moved away from the origin (0, 0), and if we move the slider very carefully for h, that would be 5 units away from the origin towards the right (along the x-axis), andk would be 7 units away from the origin) towards the bottom (along the y-axis).

After following these steps, we can replicate the circle given in the question and if we now substitute the values of h, k and r into the equation of a circle, we would end up with;

The required sample size of the given estimate is 3030.65.

Given that,
The population standard deviation is approximately σ = 50.2. You would like to be 90% confident that your estimate is within 1.5 of the true population mean.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,
For the 90% confidence the value of the z = 1.645
Now the sample size is given as,
n = [z × σ/1.5]²
Substitute values in the above equation,
n = [1.645×50.2/1.5]²
n = 3030.65

Thus, the required sample size of the given estimate is 3030.65.

Answer:

y = 24x + 17 20

Step-by-step explanation:

Firstly, let's say that 153 and 17 are both the y-intercepts of their respective equations, while 22 and 24 are the slope. With this we can create the following set of equations:

y = 24x + 17

y = 22x + 153

So your answer would be y = 24x + 17

Now let's find the sales answer!

Since we know that Ida made 4 more sales than Wade this week, we could say:

y = 24(x+4) + 17

y = 22x + 153

Now since we know that they earned the same amount we can do the following:

24(x+4) + 17 = 22x + 153

Simplify...

24x + 96 + 17 = 22x + 153

Simplify again:

24x + 113 = 22x + 153

subtract 22x and 113 from both sides...

2x = 40

Then:

x = 20

So this means that Wade made 20 sales this week!

So let's check if we are right:

Now that we know that x = 20, we need to plug it into Wade's equation!

y = 22(20) + 153

y = 440 + 153

y = 593

Wade made $593 this week!

To check if we are right, let's plug it into Ida's equation:

y = 24x + 113

y = 24(20) + 113

y = 480 +113

y = 593

Ida also made $593 this week!

MEANING we are right!

Based on the concept of multiplication, the amount of molecules consumption of water does a person drink in a year is 1.32 x 10²⁸.

Molecules:

A molecules is the group of two or more atoms linked together by sharing electrons in a chemical bond

Given,

There are about 6 x 10²⁴ molecules in a liter of water. it is estimated that a person drinks about 2.2 x 10³ liters of water a year.

Here we have to find the amount of molecules consumption of water does a person drink in a year.

To find the total amount of molecules consumption for the year we have to use the following formula,

Total molecules consumption per year = amount of water x molecules.

Here we know the values of the following,

Water consumption per year = 2.2 x 10³ liters

Molecules of one liter water = 6 x 10²⁴

Apply the values on the formula, then we get,

=> total molecules consumption = (2.2 x 10³) x (6 x 10²⁴)

=> (2.2 x 6) x (10³ x 10²⁴)

=> 13.2 x 10³⁺²⁴

=> 13.2 x ²⁷

It can be further simplified as,

=> 1.32 x 10²⁸

Therefore, the amount of molecules consumption of water does a person drink in a year is  1.32 x 10²⁸.

The age of Maggie is 9 years and her brother whose age 3 years less than four times Maggie's age is 33 years old.

What is age?

Age is the difference in days, months, and years between the day, month, and year of birth and the day, month, and year of the event, expressed in the largest completed unit of solar time, such as years for adults and children and months, weeks, days, hours, or minutes of life, as appropriate, for infants under one year of age (Gregorian calendar).

Let the ages of Maggie and her brother be X and Y.

There are two condition given in the question through which we can form a system of equation containing two equations.

First condition: The sum of their ages is 42.

Therefore,

X + Y = 42

Second Condition: Maggie's brother is 3 years younger than four times her age.

Therefore,

4X - 3 = Y

We get the system of equation:

X + Y = 42

4X - 3 = Y

Solving this system of equation

4X - 3 = Y

4X - 3 = 42 - X

X = 45/5

X = 9

Putting the value of X in one of the equation:

Y = 42 - X

Y = 42 - 9

Y = 33

Therefore, age of Maggie is 9 years and age of her brother is 33 years.
