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.
20% of 25 trees
percent=100
=20/100 of 25
=20/100 x 25
=5
=5 trees on the Jacksons property are oak trees.
Hope this helps!

associative law of addition.
Associative law of addition doesn’t matter how you group the given numbers to
add.
a + (b + c) = (a + b) + c
=> 19 + (11 + 37) or ( 19 + 11) + 37
=> 19 + (48) or (30) + 37
=> 67 or 67</span>

-6
Step-by-step explanation:
Answer: y = 
+ 30/11
Step-by-step explanation:
Two line are said to be perpendicular to each other if the slope of the first line = -1 / the slope of the second line , that is
If the slope of the first line is M1 and the slope of the second line is M2 , then M1 = -1 / M2.
From the equation given , M1 = - 11 , that means M2 = 1 / 11
Using the formula y - y1 = m ( x - x1) to calculate the equation , we have
y - 3 = 1/11 ( x - 3)
Multiply through by 11 , we have
11 ( y - 3 ) = x - 3
11y - 33 = x - 3
11y = x + 30
y = x/11 + 30/11
