Each roommate have to pay $68.85 equally.

Given, the TV costs = $275.40 including tax.

number of roommates who wants to buy a Tv with equal pay = 4

Divide the total amount of the TV among the number of roommates.

One of the four fundamental mathematical operations—the others being addition, subtraction, and multiplication—is division. Simply said, division is the process of dividing a large group into smaller groups so that each group contains an equal number of elements. In mathematics, it is an operation that is used for equal distribution and equal grouping.

⇒ 275.40 ÷ 4

= 68.85

Hence each roommate have to pay $68.85 equally to buy a TV which costs $275.50.

Number of people probably wore sandals at the mall = 9 people

Let 's' denote the total number of people Amelia counted at the mall.

Let x be the number of people wearing sandals out of them.

The equation developed by Amelia according to this is,

 s = 35x + 12

This is a linear equation written with s in terms of x .

Total people counted by Amelia = 325

So we have to find the value of x when s = 325.

Substituting s = 325 to the equation,

325 = 35x + 12

⇒ 325 - 12 = 35x

⇒ x = (325 - 12)/35

⇒ x = 8.9 ≈ 9

Since x denote the number of people wearing sandals, we take x = 9

Larger boxes may hold more or fewer balls than smaller ones. The answer to this question must be a sphere because they have the lowest volume value.

Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas.. Although there are many different units that can be used to indicate volume, the most common ones are liters, cubic meters, gallons, milliliters, teaspoons, and ounces.

According to the information provided,

One should calculate the volumes of the figures to find out if the larger box will carry more cubes or spheres, and the result that yields the smaller value must be the solution.

    Volume of cube = (edge)³ = (2 in)³

                                 = 8 in³

   Volume of sphere = (4πr³)/3

     where r is the radius and is equal to half of the length of the sides. Substituting,

            Volume of sphere = (4π)(1 in)³ / 3 = 4.19 in³

Since spheres give the smaller value for volume, the answer to this item would have to be SPHERE.

The equation representing the relationship between the area of the circle and the radius is given by A = π ( r + 16 )².

We are given that:

Waves travels at a rate of 16 feet / second.

Now, let the radius of circle be r.

Now, we know that the area of a circle is given by:

A = π r²

Now, radius increases by 16 feet every second.

So, the equation of the area will become:

A = π ( r + 16 )²

Therefore, the equation representing the relationship between the area of the circle and the radius is given by A = π ( r + 16 )².

Solving a system of equations we can see that he repaired 15 of the fiberglass bathroom sinks and 8 of the fiberglass tub enclosures

Let's define the two variables:

x = number of fiberglass bathrooms repaired.

y = number of fiberglass tub enclosures repaired.

Then we can write the system of equations:

x + y = 23

x*$12 + y*$59 = $652

Isolating x on the first one, we get:

x = 23 - y

Replacing that in the other equation:

(23 - y)*$12 + y*$59 = $652

23*$12 + y*($59 - $12) = $652

23*$12 + y*$47 = $652

y = ($652 - 23*$12)/$47 = 8

Then:

x = 23 - y = 23 - 8 = 15

So, he repaired 15 of the fiberglass bathroom sinks and 8 of the fiberglass tub enclosures

Given that you are in the 88th percentile for GPA, there are 72 students that have a GPA greater than or equal to yours.

Percentile refers to the measure used to indicate the value below which a certain percentage of data lies.

If a data is said to be in the nth percentile, this means that n% of the data in the distribution are equal to or lower than that data.

If you are in the 88th percentile, then 88% of all the 600 students have a GPA equal or lower than yours.

88% of 600 = 0.88(600) = 528

The equation of the line that passes through (2, -6) and is perpendicular to the given line is y = -x -4

From the question, we are to determine the equation of a line that passes through (2, -6) and it perpendicular to y = x + 4

If two lines are perpendicular, the product of their slope is -1.

That is,

m₁m₂ = -1

First,

We will determine the slope of the line that the equation was given

y = x + 4

Comparing with the slope-intercept form of the equation of a straight line

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison

m = 1

The slope of the line that the equation was given is 1

Thus,

The slope of the line that is perpendicular to this line is -1

From the given information,

The line passes through the point (2, -6)

Using the point-slope form of the equation of a line

y - y₁ = m(x - x₁)

Then,

y - -6 = -1(x - 2)

y + 6 = -x + 2

y = -x + 2 - 6

y= -x -4

value of the median in the situation = 49

Solution :

Median :

A Median is defined as the middle value in a given set of numbers or data. In Mathematics, there are three different measures, which are used to find the average value for a given set of numbers. They are mean, median, and mode. These three measures are called the measures of central tendency. The average value of the given data is given by mean. The middle value of the given data is defined by a median. The repeated value of the given data is defined by mode.

Mean :

The mean is estimated by dividing the sum of all the numbers by the count of the numbers.

Median Formula

Based on the definition, the formula to find the median of the dataset is given by:

If the given number of observations/data is odd, then the formula to calculate the median is:

Median = {(n+1)/2}th term

If the given number of observations is even, then the formula to find the median is given by:

Median = [(n/2)th term + {(n/2)+1}th term]/2

Where,

“n” is the number of observations.

Count of variety A  = 10

Median = [(n/2)th term + {(n/2)+1}th term]/2

Median = [(10/2)th term + {(10/2)+1}th term]/2

Median = [5th term + {6th term}]/2

Median = [49 + 49]/2

Median = [98]/2

Median = 98/2 = 49

value of the median in the situation = 49
