Probabilities are used to determine the chances of events
The probability that a randomly selected person with multiple jobs is a male or married is 0.782
<h3>How to determine the probability</h3>
The given parameters are:
Sample size, n = 655
Male = 381
Married = 299
Male and Married = 168
The number of those that are male or married is calculated as:
Male or Married = Male + Married - Male and Married
So, we have:
Male or Married = 381 + 299 - 168
Evaluate
Male or Married = 512
The probability is then calculated as:
p = 512/655
Evaluate
p = 0.782
Hence, the probability that a randomly selected person with multiple jobs is a male or married is 0.782

3xy
<span>y(3y)/3xy + y(xy)/3xy + (y+1)(3x)/3xy </span>
<span>NOW since all of the fractions have a denominator of 3xy, drop the denominators and solve using the numerators. </span>
<span>y(3y) + y(xy) + (y+1)(3x) </span>
<span>3y^2 + xy^2 + 3xy +3x </span>
<span>cannot simplify further.</span>
Its already in simplest form but you can convert it to a mixed fraction and get:
1 5/8
slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
Answer:
d
Step-by-step explanation:
Using the Cosine rule to find ∠ A
cosA =
