Answer:

For D. X= 3, or 0 but probably not 0

For the 2nd picture you sent, x= -2, or -3

Step-by-step explanation:

So for D. you want to make sure you only have 1 Variable, and since we know y=x squared + 7x+5, we subsitute y for what it is equal to.

Then we refine the question, which takes it out to

x squared-3x+5=5 (because the 7x-10x = 3x)

We subtract 5 from both sides which leaves us with x Squared - 3x= 0

Which we then solve with the Quadratic formula. and we separate the solutions to get the different answers for 3, and 0

Two fair dice are rolled 3 times and the sum of the numbers that come up is recorded. Find the probability of these events. a. T

alexandr402 [8]

Answer:

Step-by-step explanation:

Given that two fair dice are rolled 3 times and the sum of the numbers that come up is recorded.

a) The sum is 4 on each of the three rolls.

(1,3) (2,2) (3,1) HEnce for one throw prob = 3/36 =1/12

Prob for getting same sum 4 in 3 rolls = $(\frac{1}{12} )^3$

(since each trial is independent)

b) Prob sum =4 in exactly 2 rolls

= $3C2 (1/12)^2 (11/12)$ = $\frac{33}{12^3}$
