A company is considering two different prize policies for a sweepstakes. In Policy A, the cost to enter is $5. and the overall win rate is 10%. 90% of the winners receive a product worth $10. 9.5% of the winners receive a product worth $50, and 0.5% of the winners receive $250 in cash. In Policy B, the cost to enter is $10, and the overall win rate is 15%, 80% of the winners receive a product worth $10, 18% of the winners receive a product worth $50, and 2% of the winners receive $250 in cash.
The company predicts that Policy A will attract 10.000 entries, and Policy B will attract 5000 entries. Which policy makes the largest proſt for the company? By how much?
a. Policy A, by 1500
b. Policy A, by 4000
c. Policy B, by 1500
d. Policy B, by 4000
An explanation would be really awesome!
The policy that makes the largest proſit for the company is Policy A, by $1500.
Which policy makes the largest proſIt?Profit is the amount paid by people to enter the sweepstakes less the amount they can win.
Policy A's profit: $5 - 0.1[(0.9 x $10) + (0.095 x $50) + (0.005 x $250)] = $5 - 1.5 = $3.5
$3.5 X 10,000 = $35,000
Policy B's profit:10 - 0.15[(0.8 x 10) + (0.18 x 50) + (0.02 x 250) = 10 - 3.30 = 6.7$6.7 X 5000 = $33500
Difference in profits = $35,000 - 33500 = $1500To learn more about profit, please check: https://brainly.com/question/26181966

What is the number of degrees
Answer:
Step-by-step explanation:
Remark
Since this is a multiple choice question, you need not worry excessively about solving the equation that sin(4x) and Cos(3x + 13) produce. It can be done, but you will spend a lot time and drink a lot of coffee doing it.
C
The wording of this problem is not the best. 13 is not in any way considered.
4x = 4*13 = 523x + 13 = 52.Not only are the two angles equal (52) but they add to 104 which is greater than 90.
11 is the next one you should look at
4*11 = 44
3*11 + 13 = 46
That gives you the right answer, but the question you have to ask yourself is are you answering the question? I don't think you are. The question is the number of degrees in the smaller angle. I think that means that you have already substituted a value for x.
I think the answer is C.

Quinn mailed four postcards that each cost $0. 25, five letters that each cost $0. 44, two large envelopes that each cost $0. 80, and one small package for $5. 10. Which cost on the list of mailing fees on Quinn’s receipt would skew the mean? the cost of a postcard the cost of a letter the cost of a large envelope the cost of the small package.
Answer:
The cost of the small package because...
Step-by-step explanation:
Cost of 1 postcards = $0.25
Cost of 4 postcards = 0.25 x 4 = 1
Cost of 1 letter = $0.44
Cost of 5 letters = 0.44 x 5 = 2.2
Cost of 1 large envelope = $0.80
Cost of 2 large envelopes = 0.80 x 2 - 1.6
Cost of 1 small package =$5.10
Since the cost of small package is highest
So, It will increase the mean
So, the cost of the small package will skew the mean

What is AAA similarity ?The Angle-Angle-Angle (AAA) criterion for the similarity of triangles states that “If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar”.
What are corresponding angles?Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal are called corresponding angles and they are always equal.
According to the given question.
A, B and C lie on the straight line segment. and A, E, and D are also lie in the straight line segment.
Also, BE = 1.75m, CD = 7m and BC = 1.5m
Now, in ΔAEB and ΔADC
EB is parallel to BC
So,
∠AEB ≅ ∠ADC (corresponding angles)
∠ABE ≅ ∠ACD (corresponding angles)
∠EAB ≅ ∠DAC (common angle to the both triangle)
Hence, by AAA Similarity rule
ΔAEB is similar to ΔADC
Therefore,
[tex]\frac{AE}{AD} =\frac{BE}{CD} =\frac{AB}{AC}[/tex] (sides of the similar triangles are in proportion)
So,
[tex]\frac{BE}{CD} =\frac{AB}{AC} \\\implies \frac{AB}{AC} =\frac{1.75}{7} ....(i)[/tex]
Now, AC = AB + BC (as, A, B, and C lie on a straight line)
[tex]\implies \frac{AB}{AB+BC} =\frac{1.75}{7}[/tex] (from (i))
[tex]\implies \frac{AB}{AB+1.5} =\frac{1.75}{7}[/tex]
[tex]\implies 7AB = 1.75AB + 1.75(1.5)[/tex]
[tex]\implies 7AB -1.75AB = 2.625[/tex]
[tex]\implies 5.25AB = 2.625[/tex]
[tex]\implies AB = \frac{2.625}{5.25} = 0.5[/tex]
Hence, the value of AB id 0.5 unit.

a 2 -gallon container of window costs 31.36. what is the price per cup
Answer:
0.98 $/cup
Step-by-step explanation:
The final answer asks for price/cup, as "per" means "divided by".
So, our final units will be in $/cup.
We are given that for every 2 gallons, it will cost $31.36.
In order to get from gallons to cups, we need to convert units.
In 1 gallon, there are 16 cups.
So, our conversion factor will be 16 cups/1 gallon.
[tex]\frac{31.36}{2} *\frac{1}{16} \\\\= 0.98[/tex]$/cup
Important things to note:
- With these types of problems, it makes it much easier if you just figure out what units you need in the final answer, and then use conversions and dimensional analysis to get the answer

This question is designed to be answered with a calculator. which inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve f(x) = 2 cos(2x) over the interval [0, pi/ 4] using 3 equal subdivisions?
a.) l < t < r
b.) r < l < t
c.) r < t < l
d.) t < r < l
The inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is C. r < t < l.
How to illustrate the inequality?From the information given, it should be noted that f'(x) is negative. Therefore, L > R. Also since f"(x) is negative, T > R.
f(x) = 2 cos 2x.
f'(x) = -4 sin 2x
f"(x) = -8 cos 2x
Therefore, the inequality compares the left (l), right (r), and trapezoidal (t) sum approximations of the area under the curve is r < t < l

the radius of the bigger circle is 9cm and the area of the shaded region is twice that of the smaller circle then how long is the radius of the smaller circle ?
Answer:
the radius of the smaller circle = 3√3.Step-by-step explanation:
let C' be the bigger circle
and C be the smaller circle and r its radius.
Area(C') = π × (9² - r²)
Area(C) = π × r²
Area(shaded region) = area(C') - area(C)
= π × (9² - r²)
the statement “the area of the shaded region is twice that of the smaller circle ” means π × (9² - r²) = 2 × π × r²
Now, let’s solve the equation:
π × (9² - r²) = 2 × π × r²
⇔ π × (9² - r² - 2r²) = 0
⇔ π × (81 - 3r²) = 0
⇔ 81 - 3r² = 0
⇔ 81 = 3r²
⇔ r² = 27
⇔ r = √27
⇔ r = 3√3
Answer:
6.32
Step-by-step explanation:
Area of bigger circle = π(9)² = 81π cm²
Area of smaller circle = π(9)²/2 = 81π/2 = 40.5πcm²
Area scale factor = (Linear Scale factor)²
81π/40.5π = 9²/x² {cancel the π}
81/40.5 = 81/x² (cross multiplication)
81x² = 40.5 × 81
√x² = √40.5 (square root both sides)
x = 6.32
