Answer:
24 inches
Step-by-step explanation:
The perimeter of the shape is 36 inches since the other sides are given as 12 and 3, 6 will be left for the x
12 + 12 + 3 + 3 + x = 36 and x = 6
Susie then drew a square using part of this shape and one side of the square is x inches if one side is x then all fours sides will be x inches
so the perimeter of the square is 4 × x = 24 because we already know x = 6

Answer:
He wont foul out with probability 0.9093
Step-by-step explanation:
The total number of fools he picked is a Binomial ditribution noted by X with parameters p = 0.05 and N = 48. The mean of this random variable is μ = np = 48*0.05 = 2.4 and the variance is σ² = np(1-p) = 2.4*0.95 = 2.28, hence its standard deviation is σ = √2.28 = 1.51.
Note that, if approximate probability is asked, we could just approximate X with a Normal random variable with mean 2.4 and standard deviation 1.51 (this can be done because of the central limit theorem). We will calculate the probability manually. He wont foul out if he picks 0,1,2,3 or 4 fouls, thus

As a consecuence, he wont foul out with probability 0.9093.
