The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget. The cost for the production is given by y = 30x - 10. Determine the price that will allow the production of widget to break even.

Answer: E) Mean will decrease, standard deviation will decrease

Step-by-step explanation:

Initial mean = 81

Initial standard deviation = 9

New score = 78

Taking a look at the initial mean(averahe) score, which is 81 and the new score to be added to the initial scores, the initial average is greater than the new score. Hence, this will result in a decrease in the new mean score after adding the new score of 78.

Also, taking a look at the standard deviation which is 9, we can conclude that the variability in initial scores from the mean scores is high. However, the new score of 78 and the initial mean are very close, and tend to low variation. Hence, adding the new score will lead to a decrease in variability and hence a decrease in the value of standard deviation.

Answer:

u = 4/5

Step-by-step explanation:

Expand

2u - 2 - 6 = 20u - 20 - 3u

Rearrange with like terms on either side

12 = 15u

u = 4/5

Answer:

u=4/5

Step-by-step explanation:

First, parentheses/multiply on both sides.

2u-2-6=20u-20-3u <--- two negatives make a positive

Next, add/subtract like terms.

2u-8=17u-20

Then, add 8 to both sides.

2u=17u-12

Finally, get "u" by itself. Subtract "17u" to both sides and then divide "-15" to both sides

-15u=-12

u=4/5

Answer:

5

Step-by-step explanation:

24x-40=8x+40

plus 40

24x=8x+80

then u subtract 8

then u get 16x

then 80 divied by 16

u get 5

Answer:

x = 5

Step-by-step explanation:

4(6x -10) = 8x + 40

24x - 40 = 8x + 40

now were going to get the variable and the numbers on different sides

24x - 40 + 40 = 24x

8x + 40 - 8x = 40

24x - 8x = 16x

40 + 40 = 80

16x = 80

now divide each side by 16

16x / 16 = x

80 / 16 = 5

x = 5

[tex]d = \sqrt{10}[/tex]

Step-by-step explanation:

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-2-(-5))^2+(-1-0)^2}[/tex]

[tex]d = \sqrt{(-2+5)^2+(-1)^2}[/tex]

[tex]d = \sqrt{(3)^2+1}[/tex]

The required cheapest way to buy tickets is by buying 7 ticket books and 3 individual tickets.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Consumption of tickets for each person can ride the go-carts once, play video games three times, and play laser tag twice,
= 4 + 1*3 * 2*6

= 19
So each person conceded 19 tickets,
Total ticket conceded by 9 persons,
= 19 * 9
= 171 tickets
Now the cheapest option is given by,
A ticket book consists of 24 tickets so,
Dividing 171 by 24 the quotient will be the number of books and the remainder will be the individual tickects for the cheapest purchase,
= 171 / 24
= 7 + 3 / 24
quotient = 7
remainder= 3

Thus, the required cheapest way to buy tickets is by buying 7 ticket books and 3 individual tickets.

Answer:

14x+21

Step-by-step explanation:

Acute triangle; m<CDB = 180 - 130 = 50 and m<2 = 180 - 70 - 50 = 60.

remember that all angles in a triangle add up to 180°.

And angles on a straight line add up to 180°.

Answer:

Value of x is 90°

Step-by-step explanation:

Why?Imagine it as a shape of circle.

Circle has a measurement total of 360°

Semi cirlcle(half of the circle) is equivalent to 180

Now,

The bottom semi circle has a 146°

The top has a 56°

You can simply compute it by subtracting them.

[tex]146 - 56 = 90[/tex]

Step-by-step explanation:

The values of A = 1, B = 0, and C = 9 would be Ax + By = C represent the beam of light.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A flashlight shines straight up into the sky, 9 ft to the right of a tent located at the origin.

Given that the direction must be vertical, it should appear to have a consistent or constant x-coordinate.

Here Ax + By = C represents the beam of light.

So the required equation for a line is:

⇒ x = 9

Comparing the given equation, we get

Ax + By = C

Here A = 1, B = 0, and C = 9

Therefore, the values of A = 1, B = 0, and C = 9 would be Ax + By = C represent the beam of light.
