Astudent randomly draws a card from a standard deck and checks to see if it is his favorite suit. he then returns the card to the deck, shuffles, and repeats the experiment. he performs the experiments 30 times. can the probability of drawing his favorite suit be found by using the binomial probability formula? why or why not?

yes. the events are dependent; however, the 5% guideline can be applied to this situation.
no. the trials are fixed, but the probability of success changes for every trial.
no. the probability of success remains the same for every trial, but the trials are not fixed.
yes. the outcomes can be classified into two categories, the trials are fixed, and the events are independent.

its c or d   take a lucky guess my dude

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
