Two teams, A and B, are about to play a game. Previous records show that A has an 80% chance of winning, while B has a 20% of winning. Spectators can either choose to buy regular tickets or special tickets. A spectator with a special ticket will receive a refund of $2 if team A wins and a refund of $5 if team B wins. How much extra, minimally, should the special ticket cost to cover the expected value of the refunds offered?

Answer:

y=4sin(1/4x)

Step-by-step explanation:

1. Either sin or cos graph

y=asin(b(x-c))+d or y=acos(b(x-c))+d

a = amplitude

b = period (2π/b = answer)

c = x-shift (negative)

d = y-shift (positive)

2. Graph each possibility

a = 4

b = 2π/8π = 1/4

c = 0

d = 0

y=4sin(1/4x) or y=4cos(1/4x)

Suppose, 10 students have been selected for the prestigious Sir Abed Scholarship for
their excellent performances in extracurricular activities and academic results. Let’s say,
there are 4 types of award: A (100% +), B (100%), C (97%) and D (95%) . Also, a
student has an equal chance of getting any of these 4 scholarships. What is the
probability that exactly 4 of the 10 students get A and 3 students get C?

Answers

Answer:

0.1459, 0.2503

Step-by-step explanation:

Probability of getting exactly 4 A out of 10,  

P(X==4) = 10C4 (1/4)^4 (3/4)^6

=0.1459

Probability of getting exactly 3 C out of 10,  

P(X==3) = 10C3 (1/4)^3 (3/4)^9

=0.2503

The square indicates that the total angle is 90 degrees so

d+59=90

d=90-59

d=31 degrees

31 degrees
Explanation: The right angle indicator shows that the angle is 90 degrees in total. If you subtract 90-59 you end up with 31 degrees.

16b2 + 60b − 100

Answers

Answer: 4(4b - 5)(b + 5)

Step-by-step explanation:

All have a common factor of 4

4(4b^2 + 15b - 25)

--------------------------------------------------------------------------------------------------------------

Now you need to find two numbers that:

a) multiply to -100 (the a term * the c term = 4 * -25)

b) add to 15 (the b term)

After a little thinking, we can determine that the two numbers are:

20 and -5

--------------------------------------------------------------------------------------------------------------

Now we can rewrite the middle term as 20b - 5b (notice how it still equals 15b)

4(4b^2 + 20b - 5b - 25)

--------------------------------------------------------------------------------------------------------------

4((4b^2 + 20b) + (-5b - 25))

Group the terms (associative property)

--------------------------------------------------------------------------------------------------------------

Take out a common factor from each

4(4b(b + 5) - 5 (b + 5))

--------------------------------------------------------------------------------------------------------------

Now we can factor by grouping

4(4b - 5)(b + 5)

--------------------------------------------------------------------------------------------------------------

In ΔEFG, g = 53 inches, e = 65 inches and ∠F=117°. Find the area of ΔEFG, to the nearest square inch.

Answers

Answer:

[tex]Area \approx 1535\ in^2[/tex]

Step-by-step explanation:

Given

[tex]g = 53[/tex]

[tex]e =65[/tex]

[tex]F = 117[/tex]

Required

Determine the area

The area is calculated as:

[tex]Area = \frac{1}{2}absinC[/tex]

In this case, it is:

[tex]Area = \frac{1}{2}egsinF[/tex]

So:

[tex]Area = \frac{1}{2} * 65 * 53 * sin(117)[/tex]

[tex]Area = \frac{1}{2} * 65 * 53 * 0.8910[/tex]

[tex]Area = 1534.7475[/tex]

[tex]Area \approx 1535\ in^2[/tex]
