Bob and will toss two coins. if both coins come up heads, bob pays will $6. will pays bob $2 otherwise. what is the expected val

Helga [31]

Each coin has a head and a tail, therefore when you toss two coins, you have 4 possible outcomes. You have two heads in only one of these outcomes, while the other three have at least one tail.

The expected value of the game is the price paid/gained times the probability of loss/victory:

E = (1 / 4) · (-6) + (3 / 4) · (2)
= -3 / 2 + 3 / 2
= 0

Bob expects to tie with Will.

Solve the system of equations. −9y+4x−20=0−7y+16x−80=0\begin{aligned} &-9y+4x - 20=0 \\\\ &-7y+16x-80=0 \end{aligned}

gulaghasi [49]

Answer:

(x, y) = (5, 0)

Step-by-step explanation:

$\begin{aligned} &-9y+4x - 20=0 \\ &-7y+16x-80=0 \end{aligned}$

Subtract 4 times the first equation from the second:

(-7y +16x -80) -4(-9y +4x -20) = (0) -4(0)

29y = 0 . . . . . simplify

y = 0 . . . . . . . .divide by 29

4x -20 = 0 . . . . substitute 0 for y in the first equation

x -5 = 0 . . . . . .divide by 4

x = 5 . . . . . . . . add 5

The solution to this system is (x, y) = (5, 0).

What is the answer to this question

Sonja [21]

First we need to understand that the sum of adjacent angles on a straight line is 180°,meaning that when all the angles are added up the answer would be 180°

Here's how we can set up the equation:

2x+100°=180°
2x=80°
x=40°

Thus the answer is 40°

Again,hope it helps!

Step-by-step explanation:

Please consider the complete question.

A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.

We will use exponential growth formula to solve our given problem.

$y=a\cdot (1+r)^x$ , where,
