A game is played with a spinner on a circle, like the minute hand on a clock. The circle is marked evenly from 0 to 100, so, for example, the 3:00 position corresponds to 25, the 6:00 position to 50 and so on. The player spins the spinner, and the resulting number is the number of seconds he or she is given to solve a word puzzle. If 100 players are randomly selected, what is the approximate probability that the average time these players will get to solve the puzzle is between 44 and 56 seconds
Answer:
P( 44 < X < 56 ) = 0.12
Step-by-step explanation:
Number of seconds one gets to solve the puzzle ( X )
E( X ) = 100 + 0 ) / 2 = 50
Var ( X ) = 833.3333
бx = √833.3333 = 28.868
Determine The approximate probability
P( 44 < X < 56 ) = Δ time given / number of players selected
P( 44 < X < 56 ) = (56 - 44) / 100
= 12 / 100 = 0.12

Assignment: Ratio and Proportion: Molten Lava Cake
You will apply ratios and proportions to help you convert a recipe to serve more people. Use the recipe to solve the problems. The problem is your recipe only serves 8 people. Start by using the information to make 1 serving per person. Use proportions to increase the recipe to serve 30 people.
Molten Lava Cake Recipe:
1 c of sugar
6 squares of bittersweet chocolate
2 squares semisweet chocolate
1 1/4 stick butter
1/2 cup all-purpose flour
1 1/2 cups confectioners’ sugar
3 large eggs
4 egg yolks
1 tsp vanilla extract
2 1/2 tablespoons orange liqueur
Use proportions to increase the recipe to serve 30 people (1 serving per person).
Complete the table to include:
Ratio for one serving (use the table to assist you).
(i.e. If the recipe uses 1 cup of sugar, and the recipe serves 8, the ratio for one serving equals 1/8 cup sugar) thus the answer would be 1/8
Proportions used to increase recipe to 30 servings.
(i.e. for the sugar 1/(8 servings) = x/(30 servings)) thus the answer is 1/8 = x/30
Show the work to solve the proportion. Round your measurement to the nearest half. (i.e. 3.222 teaspoons rounds to 3 teaspoons, 3.666 teaspoons rounds to 3½ teaspoons, 3.89 teaspoons round to 4 teaspoons), thus the answer is 4
Scaled Recipe – Ingredient and new amount needed for 30 servings. Show the exact answer or the rounded measurement, thus the answer is 4.687 or 4 1/2
Here, we are required to apply ratios and proportions to help convert a recipe to serve more people.
The recipe for 30 people would be as follows:
4 c of sugar22 ¹/2 squares of bittersweet chocolate7 ¹/2 squares semisweet chocolate4 ¹/2 stick butter2 cup all-purpose flour5 ¹/2cups confectioners’ sugar11 ¹/2 large eggs15 egg yolks4 tsp vanilla extract9 ¹/2 tablespoons orange liqueur.The recipe in the question above only serves 8 persons.
However, we are required to convert the recipe into one that serves 30 persons.
To do that, it is important to first convert the recipe into one that serves one(1) person.
If the recipe serves 8 persons, therefore to serve 1 person, it requires dividing the quantity of each ingredient by 8.
The results are as follows:
1/8 c of sugar6/8 = 3/4 squares of bittersweet chocolate2/8 = 1/4 squares semisweet chocolate(1 1/4)/8 = 5/32 stick butter(1/2)/8 = 1/16 cup all-purpose flour(1 1/2)/8 = 3/16 cups confectioners’ sugar3/8 large eggs4/8 = 1/2 egg yolks1/8 tsp vanilla extract(2 1/2)/8 = 5/16 tablespoons orange liqueur.The new recipe above is for serving 1 person Molten lava cake.
Therefore, to serve 30 persons with the Molten lava cake, the quantity of each ingredient required for 1 person's serving i multiplied by 30.
The results are as follows:
(1/8) × 30 = 3.75 c of sugar(3/4) × 30 = 22.5 squares of bittersweet chocolate(1/4)×30 = 7.5 squares semisweet chocolate(5/32) × 30 = 4.6875 stick butter(1/16) ×30= 1.875 cup all-purpose flour(3/16) ×30 = 5.625 cups confectioners’ sugar(3/8)×30 = 11.25 large eggs(1/2) ×30 = 15 egg yolks(1/8) ×30 = 3.75 tsp vanilla extract(5/16) ×30 = 9.375 tablespoons orange liqueur.However, the question requires that the quantities be rounded off to the nearest half.
therefore we have,
4 c of sugar
22 ¹/2 squares of bittersweet chocolate
7 ¹/2 squares semisweet chocolate
4 ¹/2 stick butter
2 cup all-purpose flour
5 ¹/2cups confectioners’ sugar
11 ¹/2 large eggs
15 egg yolks
4 tsp vanilla extract
9 ¹/2 tablespoons orange liqueur.

Jane's monthly payment this year using balance billing would be $164 per month.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
To determine Jane's monthly payment this year using balance billing, we need to divide the total amount she spent last year ($1,968) by the number of months in a year.
Total amount spent last year = $1,968
Number of months in a year = 12
So, Monthly payment = Total amount spent last year / Number of months in a year
Monthly payment = $1,968 / 12
Monthly payment ≈ $164
Therefore, Jane's monthly payment this year using balance billing would be $164 per month.

find the surface area of the prism
Answer:
62ft²
Step-by-step explanation:
Hi there!
Surface area is calculated by this formula:
2(length*width)+2(width*height)+2(length*height)
*note: we multiply each area by 2, as the prisim has 6 faces, or 2 of each face
we're given a length of 5 ft, a width of 2 ft, and a height of 3ft
now let's calculate the surface area
to find the area of the first two faces:
2(length*width)
2(5*2)
2(10)
20 ft²
now to find the area of the second two faces:
2(width*height)
2(2*3)
2(6)
12 ft²
finally, find the area of the last two faces:
2(length*height)
2(3*5)
2(15)
30 ft²
now add up all the values
SA=20+12+30=62 ft²
your answer is 62ft²
