Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest

2) The second option (the bag)

8) 36 desserts

9) HH, HT, TT, TH: 1/4

Step-by-step explanation:

2)

O -  Not certain, it is possible to choose a green marble

O - Certain, all the numbers in the bag are less than 100, so the one you choose must be less than 105

O - Not certain, the spinner will not always land on the 10th letter of the alphabet

O - Not certain, the sum of the number cubes will not always be 12, depending on the number you roll

8)

The question is asking what would the sample space be of flipping a coin 2 times. You will not always alternate (heads, tails, heads, tails) when flipping a coin. This means that all of the possibilities are HH, HT, TT, TH.

Chance of getting heads = 1/2

Chance of getting tails = 1/2

Chance of getting 2 heads (divide by 2) = 1/4

Chance of getting 2 tails = 1/4

HH, HT, TT, TH: 1/4

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
