Sarah rolls two fair number cubes, each labeled 1 through 6. What is the probability of rolling a sum of 7?

Answers

Answer 1

Answer: The probability is 1/6.

Step-by-step explanation:

If two dice are rolled together, the sample space of outcomes is

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),

(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),

(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)

(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)

(6, 1), (6, 2), (6, 3), (6, 4) , (6, 5), (6, 6)

⇒ Total number of outcomes(sample space) = 36

Getting the sum 7 (favourable outcomes) = (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1).

⇒ Probability of Getting a sum 7 = Number of favourable outcomes / Total number of outcomes.

⇒ P = 6 / 36

⇒ P = 1 / 6

Check the picture below.

so the shape on 2) is simply the shape of a rectangular prism underneath a  right-cylinder, now if we take the cylinder from the prism, we have the picture as you see below, so let's simply get the area of cylinder excepting  the bottom part, and then we'll take the area of the prism excepting the cylindrical part above it.

now, the area of the prism is simply the area of 6 rectangles, and the area of the cylinder is just the area of one circle above and the lateral area of it.

[tex]\stackrel{ \textit{\LARGE area of the prism} }{\stackrel{\textit{front and back}}{(25)(5)}+\stackrel{\textit{left and right}}{(25)(5)}+\stackrel{\textit{top and bottom}}{(25)(25)}~~ - ~~\stackrel{ \textit{excepted area} }{\pi (10)^2}} \\\\\\ 125+125+625~~ - ~~100\pi ~~\approx ~~ 560.84 \\\\[-0.35em] ~\dotfill[/tex]

Answer:

1189.16 cm²

Step-by-step explanation:

So the shape on 2) is simply the shape of a rectangular prism underneath a  right-cylinder, now if we take the cylinder from the prism, we have the picture as you see below, so let's simply get the area of cylinder excepting  the bottom part, and then we'll take the area of the prism excepting the cylindrical part above it.

Now, the area of the prism is simply the area of 6 rectangles, and the area of the cylinder is just the area of one circle above and the lateral area of it.


Area of the Prism = (25 * 5) + (25 * 5) + (25 * 25) - (100 * π)

                               = 125 + 125 + 625 - 100 π

                               = 560.84 cm²(Approximately)


Area of the cylinder = (π * 10²) + (2π * 10 * 5)

                                   = 100π + 100π

                                   = 628.32 cm² (Approximately)


Total area = Area of prism + Area of cylinder

                 = 560.84 + 628.32

                 = 1189.16 cm² (Approximately)

Write in complete sentences to explain what a budget is, how to make one, and how to balance it

Answers

Answer:

Budget is the name given for the evaluation or speculative calculation of the cost of a work or service to be provided.

Step-by-step explanation:

The definition of a budget normally takes into account two main characteristics: the revenue, that is, the amount collected or available, and the expense, which would be the amount to be spent for the completion or maintenance of something. Budgets are present in various aspects of everyday life, from planning for a renovation of the house, to the amounts that will be earmarked for the maintenance of public government services, which directly or indirectly affect the lives of citizens.

Balancing a budget seems easy, but it requires a lot of self-control and discipline. Some strategies for achieving this balance are: do not spend more than what you earn, do not buy anything on impulse, do not borrow, renegotiate your debts and save on expenses that are superfluous.

Haddie makes and sells knit scarves. Next week she will pay a $25 fee for the use of a booth at a craft fair. She will charge $12 for each scarf she sells at the fair. Write an expression to determine Haddie's profit for selling s scraves after paying the fee for the use of the booth

Answers

Answer:

  p = 12s -25

Step-by-step explanation:

You want an expression for Haddie's profit from the sale of s scarves when she has revenue of $12 each and a cost of $25.

Profit

Profit is the difference between revenue and cost. Haddie's revenue from sale of s scarves is ...

  revenue = 12s

Haddie's cost is the fee she pays for the booth rental:

  cost = 25

Her profit (p) is the difference between these values:

  profit = revenue - cost

  p = 12s -25

Corinna has $64. She wants to buy a $229 plane ticket. She will save up her earnings from working at the museum where she earns $15 per hour. Which inequality shows the number of hours, n, Corinna must work so that she has a total of at least $229?
A.
n ≤ 10
B.
n ≤ 11
C.
n ≥ 11
D.
n ≥ 10

Answers

Good luck i hope you pass <3
Answer:

A. n ≤ 10

Step-by-step explanation:

Corinna wants to buy a $229 plane ticket. She currently has $64, so she needs to save up $229 - $64 = $165. Since she earns $15 per hour, we can set up the equation n * 15 = 165, where n represents the number of hours Corinna needs to work. Solving for n, we get n = 11.1, which we can round down to 11 hours. Therefore, Corinna must work at least 11 hours to save up enough money to buy the $229 plane ticket. Answer choice A is the correct answer.

Note: Rounding down to 11 is not required, as long as we do not round up to 12. Rounded or unrounded, 11 is the smallest integer greater than or equal to 11.1, so it is the minimum number of hours Corinna would need to work to save up enough money for the plane ticket.

It’s b!!

Explanation:
15 times 11 = 165
165 + 64 (she has 64 already)
= 299!

Calculate:a) Einstein's photoelectric equation may be written as: hf = 0 + mvmax.Identify the terms hf, and mvmax.b) The surface of sodium metal is exposed to electromagnetic radiation of wavelength6.5 x 10-7 m. This wavelength is the maximum for which photoelectrons are released.i. Calculate the threshold frequency.zinc plateii. Show that the work function energy of the metal is 1.9 eV.c) For a particular wavelength of incident light, sodium releases photoelectrons. State how therate of releases of photoelectrons changes with the intensity of light is doubled. Explainyour answer.glass bulbmetal.1. The energy of each photon.2. The maximum kinetic energy of each photoelectron.3. The current in the photocell.radiationvacuum1. The charge reaching the collector in 5.0 s.2. The number of photoelectrons reaching the collector in 5.0 s.ii. The work function energy of the metal is 3.5 x 10-19 J and the incident radiation hasa frequency of 7.0 x 104 Hz. Calculate the maximum kinetic energy of an ejectedMes photoelectron.iii. The intensity of the incident radiation is doubled, but the wavelength is keptconstant.
