Two fair dice are rolled 5 times. Let the random variable x represent the number of times that the sum 9 occurs. The table below describes the probability distribution. Find the value of the missing probability.

x P(x)

0 0.554928957306643

1 0.346830598316652

2 0.086707649579163

3 0.0108384561973954

4 ?

5 1.69350878084303e-05

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
