Answer:
Probability of 100 managers being selected= 100C100*1100C800/1200C900
Probability of selecting just one manager = 1C100*1199C899/1200C900
Explanation:
Given 100 managers, 200 factory workers, 900 miscellaneous workers, and workers bring transferred 900
To find probability of 100 managers leaving given that probability = number of favorable outcomes/total number of outcomes
We use combination since order doesn't matter:
Combination formula= n!/r!(n-r)! Where n= total number of outcomes and r is number of outcome at one time and ! is factorial
Probability of 100 managers using nCr formula for each item = 100C100*1100C800/1200C900
Probability of 1 manager also applying nCr formula as above =1C100*1199C899/1200C900
Depth = Volume / (length x width)

There are 15 dogs in the kennel
There are 12 cats in the kennel
Explanation:
If there is a 4 to 5 ratio then
12 cats to 15 dogs is linear
The formula for finding the area of a trapezoid is A = 1/2(b1+b2) h where A represents the area of the trapezoid, b1 and b2 are based, and h represents the height. Solve for the formula for h.
Answer:the area of triangle ABC is
346.4 feet^2
Step-by-step explanation:
The given triangle ABC is shown in the attached photo.
The formula for determining the area of a triangle is expressed as
Area = 1/2(abSinC) = 1/2(bcSinA)
A = 60 degrees
b = 40 feet
c = 20 feet
Therefore, area of the triangle is
1/2(bcSinA) = 1/2(40 × 20 × Sin60)
= 1/2 × 40 × 20 × 0.8660
= 346.4 feet^2
Alternatively, we can apply Heron's formula. We would determine the length of a by applying cosine rule,
a^2 = b^2 + c^2 -2bcCosA
Then, Heron's formula is expressed as
Area = √S(S - a)(S- b)(S - c)
Where S = (a + b + c)/2
