Answer: 48.1

Step-by-step explanation:

Julie received an amount of $134.4 when she cashed her paycheck.

Let x be the amount of the paycheck.

She gave her brother ten dollars.

She then paid $30 for the car's petrol.

So she departed with an amount equal to x-40.

She now spent half of the remaining accounts on a new camping tent.

Spent camping = (x - 40)/2

Remaining = x - 40 - (x - 40)/2

She paid $29.45 for a pair of running shoes.

Therefore, remaining =  x - 40 - (x - 40)/2 - 29.45

As per the question, she had $17.75 remaining.

So x - 40 - (x - 40)/2 - 29.45 = 17.75

Rearrange the terms and solve for x,

(x - 40)/2 = 47.2

x - 40 = 94.4

x = 134.4

Therefore, she received an amount of $134.4 when she cashed her paycheck.

Based on the rate of change and the points, the equation of the line in Point-Slope form was y = 2/3x - 4.17

The equation of the line in point-slope form was y = -1/5x - 2.8

The equation of a line takes the form:

y = mx + b

m is the rate of change

b is the y-intercept

We need to find the y-intercept because we have the rate of change and y and x values:

-6.5 = 2/3(-3.5) + b

-6.5 = -2.33 + b

b = -6.5 + 2.33

b = -4.17

The equation is:

y = 2/3x - 4.17

The equation for the second line takes the same form. So the y-intercept should be found first:

- 3 = - 1/5(1) + b

b = -3 + 1/5

b = -2.8

The equation of the line is:

y = -1/5x - 2.8

The ounces of soda consumed by an adult next month are examples of a discrete random variable,  False

A discrete random variable are known as counts. This is because it takes on only a countable number of distinct values. This means a random variable can only be considered to be discrete if it can take on values that are countable in an interval, otherwise it can be continuous.

Now on the question of ounces of soda consumed by an adult next month is considered not to be discrete random variable. This is because ounces of soda or volume of soda consumed are countless and infinite in number.  

Hence, the statement that says ounces of soda consumed by an adult next month are an example of a discrete random variable is False.

B)150 km

Step-by-step explanation:

The total distance is 400km

and jim drove 1/4 of this distance so

400 x 1/4 = 100km

then subtract this from the total distance 400 - 100 = 300km

Elaine drove 1/2 of this remaining distance

300 x 1/2 = 150 km

Add this with the first result

100 + 150 = 250 km

this is the total disrance that they have treveled

how much do they have to go

400 - 250 = 150km meaning the answer is b

The x values of the polynomial expression given as x^2 - 324 = 0 are x = 18 and x = -18

The polynomial expression is given as:

x^2 - 324 = 0

Rewrite as

x^2 + 0 - 324 = 0

Express 0 as 18x - 18x

So, we have:

x^2 + 18x - 18x - 324 = 0

Factorize the polynomial expression

x(x + 18) - 18(x + 18) = 0

Factor out x + 18

(x - 18)(x + 18) = 0

Split the factors

x - 18 = 0 and x + 18 = 0

Solve for x

x = 18 and x = -18

To use a table, we have

x^2 - 324 = 0

Set x = some values and calculate the expression

x      x^2 - 324

3     -315

6      -288

9       -243

18       0

Hence, the values of x are x = 18 and x = -18

The new grade of the student will be 70% and the grade reduced by 10 percent.

This is a rate, number, or amount in each hundred. Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.

In the given question, we simply need to add the two percentage together and find the average of the value.

This can be done mathematically as

The equation using slope - intercept from the given point.

(a) y=8x-46

(b) 8x-y=46

what is slope ?

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

Step-by-step explanation:

-y=-8x+4

y=8x+4

We know that 8 is the slope, and if we need a equation parallel to this line, then it will have the same slope.

Substitute (6,2)

2=8(6)+b

2=48+b

b=-46

In the question, we have been given that in a popular online role-playing game, players can create detailed designs for their character's "costumes," or appearance.

Malik sets up a website where players can buy and sell these costumes online.

The information about the number of people who visited the website and the number of costumes purchased in a single day is:

40 visitors purchased no costume.

82 visitors purchased exactly one costume.

6 visitors purchased more than one costume.

We need to find the probability that the next person will purchase

The equations have no solution. Therefore, the two numbers does not exist.

There are two numbers. One number is twice the other number.

The difference of the smaller number and half the larger number is 20.

The equation that can be use to represent the situation can be represented as follows;

Hence,

let the two numbers be x and y.

2x = y

x - 1 / 2 y = 20

Option B: 4x²-x+3

(4x³ + 11x² + 0x + 9) + (x+3) [here, we will include 0x to do long division]

Divide 4x³ by x to get first term of the quotient, 4x³

Then, take 4x² and multiply it with 3 and you will get 4x² + 12

Subtract 4x² + 12 from 4x³ + 11x².

Then, you will get the remainder as -x² + 0x

Now you have to repeat the same same process, divide -x² by x to get second term of quotient, -x

Then take -x and multiply with 3 and you will get -x²- 3x

You will get the remainder as 3x+ 9

Divide 3x by x to get the third term of quotient, 3

Then, take 3 and multiply with 3 and you will get 3x + 9

Subtract and you will get the remainder as 0.

The slope is 1.

Explanation:

The equation of a line is written in "slope-intercept form as

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula,

y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula t.

Using a straight line's slope and the location of its y-axis intersection, the slope intercept equation can be used to determine the general equation of the line. Y = mx + b is the equation in slope intercept form.

The slope-intercept form is provided as y = mx + b, where m is the line's slope and b is the y-intercept. Using this form, we may determine the slope of a line. Here's an illustration. The slope of the line 6x - 3y = 5 should be determined. To convert this into the slope-intercept form, let's solve this for 'y'. The result is y = 2x – (5/3). We calculate the slope to be m = 2 by comparing this to the slope-intercept formula, y = mx + b.

Based on amortization loan formula, Melissa should make a monthly payment of $4.21494.

The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.

Assuming the loan exists compounded monthly, the total monthly payment exists estimated from the amortization formula as peruses:

[tex]$A=P(i(1+i)^n)/((1+i)^n-1)[/tex]

Where, A be the monthly payment

P be the amount borrowed = $ 6000

i be the monthly interest = 0.0311/12

n be the number of months = 4 × 12 = 48 months

Calculating the monthly payment:

substitute the values in the above equation, we get

[tex]$\frac{6000\left(\frac{0.03}{12}\left(1+\frac{0.03}{12}\right)^{48}\right)}{(1+0.03)^{48-1}}[/tex]

simplifying the above equation, we get

[tex]$=\frac{6000 \cdot \frac{0.03}{12}\left(1+\frac{0.03}{12}\right)^{48}}{(1+0.03)^{48-1}}$$[/tex]

[tex]$(1+0.03)^{48-1}=1.03^{47}$[/tex]

[tex]$=\frac{6000 \cdot \frac{0.03}{12}\left(\frac{0.03}{12}+1\right)^{48}}{1.03^{47}}$[/tex]
