Expenses and receipts will total $2800 after 200 hours.

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

Explanation:

x = number of hours

Ron spends $11 an hour for operating costs. He spends 11x dollars on top of the $600 he spent on the equipment. The cost expression is 11x+600

On the flip side, Ron earns (on average) $14 an hour from the receipts or revenue. Overall, he earns 14x dollars.

Often in business applications, the owner is curious when s/he will break even. This is the point where the profit is 0 dollars, ie when cost = revenue.

So we'll set the two expressions equal to one another and solve for x.

cost = revenue

11x+600 = 14x

600 = 14x-11x

600 = 3x

600/3 = x

200 = x

x = 200

At the 200 hour mark is when Ron is likely to break even.

This x value leads to:

We get the same cost for each expression, helping to confirm that x = 200 is correct.

The bakery's expenses and receipts will total $2800 after 200 hours.

Answer:

Rounding up to the nearest hundredth, 907.49

Step-by-step explanation:

10% of 824.99 is 82.499 so all you have to do is 824.99 + 82.499 which will get you 907.48900 and rounding to the nearest hundreth will get you 907.49

Step-by-step explanation:

10% of 824.99 = 82.499

then 824.99 +82.499= 907.489

rounded off = 907.49

Answer:

22.  [tex](x-1)^2+(y+2)^2=74[/tex]

26.  [tex]x^2+y^2=81[/tex]

Step-by-step explanation:

The center of a circle is the midpoint of the diameter.

[tex]\textsf{midpoint}=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

(where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of the diameter)

The radius of the circle is the distance between the center and an endpoint of the diameter.

[tex]\textsf{radius}=\sqrt{(a-x_1)^2+(b-y_1)^2}[/tex]

(where [tex](a,b)[/tex] is the center of the circle, and [tex](x_1,y_1)[/tex] is an endpoint of the diameter)

The center-radius form of a circle: [tex](x - a)^2+(y-b)^2=r^2[/tex]

(where (a, b) is the center and r is the radius)

Question 22

[tex]\textsf{Let }(x_1,y_1)=(-4.5)[/tex]

[tex]\textsf{Let }(x_2,y_2)=(6,-9)[/tex]

[tex]\textsf{center}=\left(\dfrac{-4+6}{2},\dfrac{5-9}{2}\right)=(1,-2)[/tex]

[tex]\textsf{radius}=\sqrt{(1+4)^2+(-2-5)^2}=\sqrt{74}[/tex]

⇒ equation of circle: [tex](x-1)^2+(y+2)^2=74[/tex]

Question 26

[tex]\textsf{Let }(x_1,y_1)=(0,9)[/tex]

[tex]\textsf{Let }(x_2,y_2)=(0,-9)[/tex]

[tex]\textsf{center}=\left(\dfrac{0+0}{2},\dfrac{9-9}{2}\right)=(0,0)[/tex]

[tex]\textsf{radius}=\sqrt{(0-0)^2+(0-9)^2}=9[/tex]

⇒ equation of circle: [tex]x^2+y^2=81[/tex]

Using the normal distribution, it is found that:

a) There is a 0.0228 = 2.28% probability that a randomly chosen salary exceeds $35,000.

b) There is a 0.3085 = 30.85% probability that a randomly chosen salary is less than $22,500.

c) There is a 0.4938 = 49.38% probability that a randomly chosen salary lies between $25,000 and $37,500.

d) The 15th percentile of the sociology salaries is of $19,825.

e) The salaries are $20,800 and $29,200.

In a normal distribution 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]

In this problem:

Item a:

The probability is 1 subtracted by the p-value of Z when X = 35000, hence:

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

[tex]Z = \frac{35000 - 25000}{5000}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a p-value of 0.9772.

1 - 0.9772 = 0.0228.

There is a 0.0228 = 2.28% probability that a randomly chosen salary exceeds $35,000.

Item b:

The probability is the p-value of Z when X = 22500, hence:

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

[tex]Z = \frac{22500 - 25000}{5000}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a p-value of 0.3085.

There is a 0.3085 = 30.85% probability that a randomly chosen salary is less than $22,500.

Item c:

This probability is the p-value of Z when X = 37500 subtracted by the p-value of Z when X = 25000, hence:

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

[tex]Z = \frac{37500 - 25000}{5000}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a p-value of 0.9938.

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

[tex]Z = \frac{25000 - 25000}{5000}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a p-value of 0.5.

0.9938 - 0.5 = 0.4938

There is a 0.4938 = 49.38% probability that a randomly chosen salary lies between $25,000 and $37,500.

Item d:

This is X when Z has a p-value of 0.15, so X when Z = -1.035.

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

[tex]-1.035 = \frac{X - 25000}{5000}[/tex]

[tex]X - 25000 = -1.035(5000)[/tex]

[tex]X = 19825[/tex]

The 15th percentile of the sociology salaries is of $19,825.

Item e:

Due to the symmetry of the normal distribution, it is the 20th percentile and the 80th percentile, that is, X when Z = -0.84 and X when Z = 0.84.

20th percentile:

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

[tex]-0.84 = \frac{X - 25000}{5000}[/tex]

[tex]X - 25000 = -0.84(5000)[/tex]

[tex]X = 20800[/tex]

80th percentile:

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

[tex]0.84 = \frac{X - 25000}{5000}[/tex]

[tex]X - 25000 = 0.84(5000)[/tex]

[tex]X = 29200[/tex]

The salaries are $20,800 and $29,200.

Answer:

SA = 76 yd²

Step-by-step explanation:

Use the formula given:

The units are yards²

SA = 76yd²

-Chetan K

The surface area of the rectangular prism is 76 square yards

The dimensions of the rectangular prism are given as:

Length (l) = 4 yards

Width (w) = 2 yards

Height (h) = 5 yards

The surface area (SA) is calculated as:

SA =2lw + 2lh + 2wh

So, we have:

SA = 2 * 4 * 2 + 2 * 4 * 5 + 2 * 2 * 5

Evaluate the expression

SA = 76

Hence, the surface area of the rectangular prism is 76 square yards
