Which of the following random variables is geometric? (2 points) a The number of 4s in a row of 50 random digits. b The number of digits in a randomly selected row until a 4 is found. c The number of tails when a coin is tossed 30 times. d The number of spade cards obtained in a seven-card deal-out of a shuffled deck of 52 cards. e The number of 4s when rolling a die 5 times.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
