<span>This statement is always true. For any two nonzero integers the product and quotient have the same sign. For example, -2*-3 = 6 and of we see -2/-3, then the result is 2/3. The sign in the result is same after product and quotient, but the result has the same sign.</span>

Answer:
Area of rhombus = 96 inch²
Step-by-step explanation:
Given:
Side length of rhombus = 10 inch
Length of longer diagonal = 16 inch
Find:
Area of rhombus
Computation:
We know that, diagonals of rhombus perpendicular bisect each other
So,
Half of small diagonal = √Side length of rhombus² - Half length of longer diagonal²
Half of small diagonal = √10² - 8²
Half of small diagonal = √100 - 64
Half of small diagonal = √36
Half of small diagonal = 6 inch
Length of smaller diagonal = 2 x 6
Length of smaller diagonal = 12 inch
Area of rhombus = (Product of diagonals)/2
Area of rhombus = (16 x 12)/2
Area of rhombus = 96 inch²

Answer:
a) 0.5233 = 52.33% probability of picking someone who has the disease.
b) 0.9091 = 90.91% probability of picking someone who tests negative, given that he/she did not have the disease
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
a) What is the probability of picking someone who has the disease.
132 + 25 = 157 people have the disease
132 + 25 + 13 + 130 = 300 people total
157/300 = 0.5233
0.5233 = 52.33% probability of picking someone who has the disease.
b) What is the probability of picking someone who tests negative, given that he/she did not have the disease?
143 people did not have the disease.
130 tested negative. So
130/143 = 0.9091
0.9091 = 90.91% probability of picking someone who tests negative, given that he/she did not have the disease
