Answer:
x = 7
Step-by-step explanation:
Expand 3x+2(x-5)=25 which looks like
3x+2x-10=25
Add similar elements: ( 3x+2x = 5x)
5x-10=25
Add 10 to both sides
5x-10+10 = 25 + 10
Simplfy
5x = 35
Divide both sides by 5
5x ÷ 5 = 35 ÷ 5
Simplfy:
x = 7
have a wonderful day

Answer:
It is a Binomial experiment with n = 8 and p = 0.25
Step-by-step explanation:
It is given that we draw 8 cards out of the well shuffled deck of 52 cards one by one replacement.
Given :
![$n=8$](https://tex.z-dn.net/?f=%24n%3D8%24)
P (getting a spade) = ![$\frac{13}{52}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B13%7D%7B52%7D%24)
= 0.25
As in the question, we are sampling with the replacement, so the probability of getting a spade in each draw remains the same and the all the draws are independent.
Therefore it is a Binomial experiment with n = 8 and P = 0.25
