Which function is the inverse of f(x) = 8x + 4? A. B. C. D.

Answers

Answer 1

Answer:

x = -1/2

Step-by-step explanation:

To find x-intercepting/zero, substitute  f(x) = 0

0 = 8x + 4

move the variable to the left hand side and change its sign

-8x = 4

divide both aides of the equation by -8

x = -1/2

At 8% sales tax, the total price of a color TV whose marked price is $425 is
A)$451
B)$459
C)$465.25
D)$425.75

Answers

Answer:

B 459

Step-by-step explanation:

After adding the sales tax of 8% to the marked price of the TV, the price of the TV will be equal to $459. Hence, option B is correct.

What is the Percentage?

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages.

In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given data in the question,

Sales tax on TV = 8%

Marked price of TV = $425

The total price of the TV, T = Tax + Marked Price

T = 8% × $425 + $425

T = $34 + $425

T = $459

Hence, the total price is $459.

A library spent 5/8 of its budget to buy new books. They set aside 1/12 of the book money to buy young adult novels. What part of the budget went towards buying young adult novels?

Answers

Answer:

5/96

Step-by-step explanation:

Fraction used to buy new books = 5/8

Amount for book money = 1/12 of amount of adult novels

Part used for adult movies = 1/12 * 5/8

Part used for adult movies = 5/96

Hence the  part of the budget that went towards buying young adult novels is 5/96

Graph the following equation by plotting two points.

y-5=-2(x+7)

Answers

Answer:

Here we have the linear equation:

y - 5 = -2*(x + 7)

First, we need to isolate the variable y in one side of the equation, so it is easier to handle:

y = -2(x + 7) + 5

Now we need to find two points that belong to this line.

To do it, we can just replace the x-value by two different values, and find the correspondent y-value for each.

For example, if we replace x by 0 we get:

y = -2*(0 + 7) + 5 = -2*7 + 5 = -14 + 5 = -9

Then we have the point (0, - 9)

Now we can use x = 1

y = -2*(1+7) + 5 = -2*8 + 5 = -16 + 5 = -11

We have the point (1, - 11)

Now you just need to draw these two points, and draw a line that connects them.

That line is the graph of the linear equation, you can see an example of this in the graph below.

there are 47 numbers Find the probability that i will pick the 6 winning numbers in a draw​

Answers

Answer: You have six numbers on your ticket. In drawing the first number from the collection of 45, one of those six numbers must be drawn in order for you to still have a chance of winning the big prize. So following the draw, the probability is only 6/45 (or 1/9) that you’re still in the game.

You can now see that on each successive draw the probability steadily drops- to 5/44, 4/43, 3/42, 2/41, and for the last number 1/40. As other answers have stated, there are 8,145,060 possible draws of six numbers and only one makes you a winner.

If you bought ten tickets for every drawing, the odds reach a 50% chance of having won at about 520,550 drawings. Assuming two drawings per week, the chance of winning reaches 50% in about 5,200 years.

Of course, SOMEONE will win and if you don’t play, your chance of winning is zero. It’s kind of fun to occasionally buy lottery tickets just for the dream of winning but don’t spend a lot of money on them.

A study finds that the number of gallons of water used each month per household in a
residential neighborhood are normally distributed with a mean of 470 gallons and a
standard deviation of 50 gallons. A household is randomly selected. What is the
probability that the household uses 480 gallons of water or less per month?

Answers

Answer:

0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 470 gallons and standard deviation of 50 gallons.

This means that [tex]\mu = 470, \sigma = 50[/tex]

What is the probability that the household uses 480 gallons of water or less per month?

This is the pvalue of Z when X = 480. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{480 - 470}{50}[/tex]

[tex]Z = 0.2[/tex]

[tex]Z = 0.2[/tex] has a pvalue of 0.5793

0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month

*** the opposite side of the 7 is also 7, same with the 11 :)

to find the area for a rectangle, you use the formula A=b*h

so, the base(b)=7 and the height(h)= 11

A gardener makes a new circular flower bed. The bed is teen feet in diameter. Calculate the circumference and the area of the circular flower bed.

Answers

Answer:

I. Circumference of circular flower bed = 31.42 ft.

II. Area of circular flower bed = 78.55 ft²

Step-by-step explanation:

Given the following data;

Diameter = 10 ft

Radius = diameter/2

Radius = 10/2

Radius, r = 5 ft

I. To find the circumference of the circular flower bed;

Circumference of circle = 2πr

Substituting into the formula, we have

Circumference of circular flower bed = 2*3.142*5

Circumference of circular flower bed = 31.42 ft

II. To find the area;

Area of circle = πr²

Substituting into the formula, we have;

Area of circular flower bed = 3.142*5²

Area of circular flower bed = 3.142*25

Area of circular flower bed = 78.55 ft²
