Based on the date given "being male" and "earning over $50,000" are NOT mutually exclusive events. That is "No, P(being male | the person earns over $50,000) ≠ P(being male)" (Option C)
Two events are independent or mutually exclusive if they are distinct from one another and cannot alter the reaction of one another.
Calculation
=0.55 x 0.87
= 0.4785
Thus, probability of being male and earning over $50,000
= 485/550
= 0.8818
Hence, we can state that P(being male | the person earns over $50,000) ≠ P(being male)

county X?
A a parallelogram with a base of 25 miles and a height of 25 miles
B a rectangle that is 15 miles long and 45 miles wide
C a right triangle with a leg that is 30 miles long and a hypotenuse that is
50 miles long
D a trapezoid with base lengths of 10 miles and 30 miles and a height of
25 miles
Answer:
Option C. is the correct option.
Step-by-step explanation:
County X has a population density of 250 people per square mile.
Total population of the county is 150000.
Total area which represents the population = = square mile.
So geometric model which has the same area as 600 square miles will be the answer.
A). Area of a parallelogram = Base × height
= 25×25
= 625 square miles
which is not equal to 600 square miles so it's not the correct option.
B). Area of a rectangle = Length×width
= 15×45 = 675 square miles ≠ 600 square miles
Therefore, not the correct option.
C). Area of a right triangle =
Since length of hypotenuse is given so we will find the length of height.
Height = √[(Hypotenuse)²- (Base)²] =
=
=
= 40 miles
So area of the right triangle =
=
= 600 square miles
Which matches the area of County X, so it's a correct option.
D). area of trapezoid =
=
=
= 20×25
= 500 square miles ≠ 600 miles
Therefore, this option is not correct.
