Answer:

450 $ in tottle for every candle she sold.  

Step-by-step explanation:

The area of the rectangle is  (14 + 1/3)  square yards.

We know that for a rectangle of length L and width W, the area is:

A = L*W

Here we know that:

L = (4 + 2/3) yards.

W = (3 + 1/4) yards.

We just need to take the product between these two numbers, we will get:

area =  (4 + 2/3)* (3 + 1/4) yd²

Expanding the product:

(4 + 2/3)* (3 + 1/4) yd² = [ 4*3 + 4*(1/4) + (2/3)*3 + (2/3)*(1/4)] yd²

                                    = [ 12 + 1 + 2 + 2/6] yd²

                                     = (14 + 1/3)  yd²

That is the area of the rectangle.

Step-by-step explanation:

Answer:

$537.87

Step-by-step explanation:

First, we need to determine our total pay which will be 40 hours times our $15 per hour to be $600. For the extra hours above 40, we are payed 1.5 times as much.

$15 * 1.5 = $22.5 * (44-40) = $90 additional pay

$600 + $90 = $690 total pay

Now, we calculate all of our deductions.

Subtract social security to be

690 * (1-0.0625) = $646.875

Medicare Deduction

646.875 * 0.9855 = $637.50

Health Insurance

$637.50-83 = $554.50

401k Deduction

$554.50 * 0.97 = $537.87

Step-by-step explanation:

Given that:

Path of sprinkler is modeled by the quadratic function :

w(x) = -1/4(x^2 -12 )

w(x) = height of the water, in meters, at position x

The height of ceiling as a constant or Coefficient = w(x)

Expanding w(x)

-1/4(x^2 -12 )

-1/4 * x² + 1/4 * 12

-1/4x² + 3

The height of ceiling is -1/4x² + 3

The amount of the investment after 8 years will be, $4,357.64

Given, $500 is invested in an account earning 7% interest compounded quarterly.

We have to find the value of the invested amount after 8 years,

as, Amount = P(1 + r/100)^t

where, P is the amount of money invested, r is the rate of interest and t is the amount of time

Amount = 500(1 + 7/100)^(8×4)

Amount = 500(1.07)^32

Amount = 500×8.715

Amount = 4,357.635

So, the amount of the investment after 8 years will be, $4,357.64

Step-by-step explanation:

The figure can be shown to be a parallelogram by showing the sum of endpoints of the diagonals is the same.

  A +C = B +D

  (0, 6) +(0, -4) = (0, 2) = (3, 5) +(-3, -3) . . . . diagonals bisect each other

If the diagonals of a quadrilateral bisect each other, it is a parallelogram. A parallelogram with a right angle is a rectangle. So, ABCD is a rectangle.

_____

Additional comment

The midpoint of each diagonal is half the sum of the end point coordinates. That is, the midpoints are (0, 2)/2 = (0, 1). Since calculation of the midpoints requires both sums be divided by 2, we can tell the midpoints are the same if the sums are the same.

Yes, because opposite sides are parallel, and \angle A∠Aangle, A is a right angle.

Complete question is;

A. imagine that you are one of the people who left the luncheon with a contagious disease and interacted with an average of 9 different people each day. how many people could potentially be infected in 7 days?

b. imagine the other remaining persons who received the contagious disease at the end of the luncheon interacted with an average of 6 different people per day. how many people could potentially be infected in 7 days by these others who left the luncheon?

Answer:

A) 63

B) 294

Step-by-step explanation:

A) We are told that the person that has the disease comes in contact with an average of 9 persons each day. Thus, for 7 days, he would have infected;

Number of people infected for 7 days = 9 × 7 = 63 people

B) If patient zero is excluded, there will be seven other people in the experiment. Now, we are told that each of them interacted with 6 different people every day in 7 days.

Thus, number of people infected each day = 7 people infected x 6 new people = 42 infected people each day,

Them for 7 days;

= 42 infected people each day x 7 days = 294 infected persons.

Answer:14.4222

Step-by-step explanation:

A linear regression equation was used to predict the number of car accidents a person would experience based on their score on the driving test. The equation predicts that a person with a score of 6 out of 10 would experience 0.1 car accidents.

To do this, they performed a linear regression equation. This equation is used to predict the dependent variable (number of car accidents) based on the independent variable (score on the driving test). To obtain the results, the department of motor vehicles used the equation to calculate the predicted number of car accidents for each possible score on the driving test. Using these results, we can predict that a person with a score of 6 out of 10 would experience 0.1 car accidents. The equation used to make the prediction is Y = a + bX, where Y is the number of car accidents, a is the intercept of the regression line, b is the slope of the regression line, and X is the score on the driving test. To calculate these values, the department of motor vehicles must collect data on driving tests and car accidents and fit a regression line to the data.

The distance Jeremey swims in a day is 4/5 Kilometers per day.

Solving:

(28/5)/7 = 28/7x5 = 4/5 kilometers per day

{when I put the / it means fraction}

explanation:

You have to turn 5 3/5 into an improper fraction, and do to do that you have to do 5 x 5 = 25 then 25 + 3 = 28/5

so in a 7 day period she swims 5.6 kilometers. So you have to do 5.6/7 = 0.8

So it would be 0.8 kilometers in a day which is 4/5 kilometers

To multiply a decimal by 10, move the decimal point in the multiplicant by one place to the right. Here we multiplied the number 1.6 by 10 so we move 1 place to the right.

To multiply a decimal by 100, move the decimal point in the multiplicant by two places to the right.

The shaded area under the curve is equal to 0.6826.

From the information provided, we have the following parameters:

Mean, μ = 501

Standard deviation, σ = 55.00

In this exercise, you are required the shaded area under the curve and this can be represented or modeled by this mathematical expression:

446 ≤ x ≤ 556

The lower limit (boundary) is equal to 446 i.e x₁ = 446.

The upper limit (boundary) is equal to 556 i.e x₂ = 556.

Next, we would determine the z-score for both limits as follows:

Z-score = (x₁ - μ)/σ

Z-score = (446 - 501)/55.00

Z-score = -55/55.00

Z-score = -1.00

For the upper limit, we have:

Z-score = (x₂ - μ)/σ

Z-score = (556 - 501)/55.00

Z-score = 55/55.00

Z-score = 1.00

By using a z-score calculator, the area is given by:

P(446 ≤ x ≤ 556) = P(-1.00 ≤ x ≤ 1.00)

P(-1.00 ≤ x ≤ 1.00) = P(x ≤ 1.00) - P(x ≤ -1.00)

P(-1.00 ≤ x ≤ 1.00) = 0.6826.

Step-by-step explanation:

Alright so range is how far the function goes in the y direction while domain is how far the function goes in the x direction. For letter a, to find the range you would look at how high the y-values go for the graph. In this problem, the highest the graph goes is y=3 and the lowest the graph goes is y=1. This means that Range is [1,3]. The closed brackets mean the function is actually hitting the value 1 and 3 while open brackets, (x,y), mean the value does not actually hit those values. For the domain of letter a, we will look at how far the function continues in the x direction. Since the function has arrows on the end going left and right, that means that the function continues on the x-axis forever, making the domain       (-∞,+∞). They are open brackets because a value can never actually be infinity. To show if it's a function, we perform the vertical line test. Basically, you put an imaginary vertical line across the whole graph and see if that line hits the function more than once. If it doesn't, like a, it's a function. If it does hit the graph twice like c, it is not a function. I hope this all makes sense.
