Answer:

-25 1/2 =e

Step-by-step explanation:

3 e - 8 = 5 e + 43

Subtract 3e from each side

3 e - 8 -3e = 5 e-3e + 43

Simplify

-8 = 2e +43

Subtract 43 from each side

-8-43 = 2e+43-43

Simplify

-51 = 2e

Divide each side by 2

-51/2 = 2e/2

Simplify

-25 1/2 =e

Steps to solve:

3e - 8 = 5e + 43

~Add 8 to both sides

3e - 8 + 8 = 5e + 43 + 8

~Simplify

3e = 5e + 51

~Subtract 5e to both sides

3e - 5e = 5e - 5e + 51

~Simplify

-2e = 51

~Divide -2 to both sides

-2e/-2 = 51/-2

~Simplify

e = -25 1/2

Best of Luck!

Although I don't see 1950, 1988, or 2010 on your model, I did calculate the average for 1972, 1982, 1992, and 2002: the average that I got was 1.6025 (this answer has not been rounded due to the fact that I don't know if you need to round it)
hope this helps

Answer:

60°

Step-by-step explanation:

Assuming the dot is the center of the circle, all sides of the triangle appear to be equal (i.e., 7). This means all its angles must be 60° (180° divided equally), so the angle is 60°.

In the New York State number lottery, you pay $1 and pick a number from 000-999. If your number comes up, you win $500, which is

slava [35]

Answer:

Expected value of profit is ≅ $15.80

Step-by-step explanation:

from the Question,

Let the variable X represents the expected value of profit. X is called as random variable because picking a number from 000-999 digits is a Random process.

P(win) = $0.001$

So, P(lose) = $1-0.001=0.999$

Suppose that,

we really want to win this lottery. so we can go to the store and spend $1000 to buy all ticket (from 000 - 999). This would ensure your winning of $500 with one of the tickets (for a $499 profit), but the other 999 would be losers (for a $999 loss).

What would be your average winnings on a per-ticket basis?

$u = E(x) =$ ∑ $x\times P(x)$
