Answer 1

Answer:

grab ur calculator for these. when dividing, they will end up in decimal format. for it to be a precentage, take that number and multiply by 100 to get a percent.

To convert back to fractions, divide the number by 100

eg 7%

7/100

that's the fraction. (decimals is just the full dividing)

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given a graph of a function f(x).

The graph is a straight line where there is a unique value of y for each value of x.

We have to calculate the value of x when y = 7.

Taking the y coordinate to 7, the x coordinate corresponding to the y coordinate is 5.

Hence the value of x is 5.

(PLEASE ANSWER ILL GIVE YOU 20 POINTS) Determine if the relation is a function. If the relation is a function, find the domain and range.Required to answer. Single choice.

Answers

Answers:

The relation is a function

Domain = {-2, -1, 0, 1, 2}

Range = {-2, 0, 2}

=================================================

Explanation:

The blue points shown are

(-2,-2)

(-1,0)

(0,2)

(1,0)

(2,-2)

Note how the x values do not repeat themselves. Visually this graph passes the vertical line test. It is impossible to draw a single straight vertical line through more than one blue point at a time. It tells us that any x input leads to exactly one y output.

The relation is a function

The domain is the set of x coordinates of the points

Domain = {-2, -1, 0, 1, 2}

The range is the set of y coordinates of each point

Range = {-2, 0, 2}

Toss out any duplicate items that may occur in the range.

Answer:

The relation is a function.

The domains are 2, 1, 0, -1, -2.

The ranges are -2, 0, 2, 0, -2

Answer:

Total interest = A - P = $2,223.00

Total amount = $10,023.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9.5%/100 = 0.095 per year.

Solving our equation:

A = 7800(1 + (0.095 × 3)) = 10023

A = $10,023.00

The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

What is an equation in point slope form of the line that passes through (7, 1) and (-3,9)

Answers

Answer:

y= -4/5x+33/5

Step-by-step explanation:

for questions like these, the slope is always defined as the change in y over the change in x or use the equation m=y2-y1/x2-x1.

x1=7 and y1=1

x2=-3 and y2=9

now plug these numbers in to the equation. m= 9-1 / -3-7 Or m= 8/-10 simplified to m= -4/5

now that we have the slope you can plug it in to the equation y=mx+b and get y= -4/5 + b.

to find b, the y-intercept, you can use either of the two points and the answer will be the same. for this one, I'll use (7,1).

1= -4/5 x 7+b. b= 33/5

A college accepted new applicants, of whom 56% were male and 44% were female. The board of directors was not pleased that males were being accepted at a greater percentage than females. A private company investigated and found each department accepted a greater percentage of females over males. What may make this claim possible?

Answers

Answer:

Simson paradox

Step-by-step explanation:

In Simpson paradox, the trend that appears in the combined data reverses or disappears in the results of the several individual groups that make up the combined data

In the question, given that the percentage of female applicants accepted = 44% while the percentage of male applicants = 56%, and that the private company found that each department accepted a greater percentage of females over males

The above claim can occur when there is a confounding variable, which is the number of applications from female or male

The percentage used or the data provided to by the private company in each department are percentage in proportion of number of accepted females to total number of female applicants and percentage in proportion of number of accepted males to total number of male applicants, whereby, when there are fewer number of female applicants to each department and more were accepted, their percentage will be larger than the percentage of the male applications that have a lower percentage but larger number of applications, such that the accepted male applicants still outnumber the female when that total number of applications are considered.

Susan buys a new computer 1200 dollars.Sales tax is 11%. How much does Susan actually have to pay?

Answers

Start by finding 11% of 1,200. To do so, multiply .11 by 1,200 to get 132. Add 132 to 1,200 to get 1,332.

In short, Susan has to pay *$1,332*

The amount that Susan actually have to pay should be considered as the $1,332.

Calculation of the amount:

Since the purchase price of the computer is $1,200

And, the sales tax rate is 11%

So here the total amount be like

= $1,200 + 11% of $1,200

= $1,200 + $132

= $1,332

hence, The amount that Susan actually have to pay should be considered as the $1,332.

Step-by-step explanation:

8(x - 2) + 9 < 3(x - 1) + 5x

Distribute

8x - 16 + 9 < 3x - 3 + 5x

Combine like terms

8x - 7 < 8x - 3

Subtract 8x to both sides

-7 < -3

Since -7 is less than -3, there are many infinitely solutions to this equation.
