Answer:

I think they are all combination because order doesn't matter but I don't have a calculator with me to give you EXACT answers for all of them

Step-by-step explanation:

I think combinations because order doesn't matter; or it isn't mentioned. I could be wrong as I'm still learning and confused with finite as well. But to do these, you would do the formula of the probability of an event which is E= favorable outcome/total probabilities.. so for all men 7c6/18c6 and then do the same thing for the rest but for the right ratios and whatnot.

Solve the system by substitution y-4x 8x-4y=-40

Andru [333]

Answer:

X = 10/3

Step-by-step explanation:

8x - 4y = -40

y - 4x

For brainly and points

Anna [14]

Answer:

Step-by-step explanation:

Given

$\frac{2}{3}$ m + 5 = 17 ( subtract 5 from both sides )

$\frac{2}{3}$ m = 12 ( multiply both sides by 3 to clear the fraction )

2m = 36 ( divide both sides by 2 )

m = 18 → C

elena-14-01-66 [18.8K]

Answer:

-0.5 is the answer

Step-by-step explanation:

ARRANGING THE VALUE IN ASCENDING ORDER

-6,-4,-0,-1,-1,0

N=6(counting the above numbers of ascending order)

Position of median=(N+1/2)th items

=(6+1/2)th items

=(7/2)th items

=(3.5)th items

IF THE ANSWER IS IN POINT YOU SHOULD FIND THE AVERAGE,

3.5th itemsis the average of 3rd and 4th items

Median=-0+(-1)/2

=-0-1/2

=-1/2

=-0.5
