Answer:
you just multiply the values inside the parentheses. 11 x -4 x 12, so its -44 x 12, being -528
Step-by-step explanation:
Answer:
(D) 200 men and 2,000 women
Step-by-step explanation:
To have an approximately normal distribution for the difference between proportions, we have to have sample sizes that are big enough to satisfy this conditions:
For men, we have p=0.08, so we have:
The sample size for men has to be at least 125 individuals.
For women, we have p=0.005:
The sample size for women has to be at least 2000 individuals.
The option that satisfy the requirements for men and women is Option D, as the others don't have enough sample size for women.
Answer:
DB = 6
Step-by-step explanation:
See the attached figure to the question.
Since O is the center of the given circle, so AB and CD are diameters of the circle.
Hence, AO = CO = OD = OB = radius of the circle = 6
In Δ OAC, we have AO = OC. Hence, ∠ A = ∠C = 60° {Given that ∠OAC = 60°}
So, ∠ AOC will automatically become 60°. {As the sum of all the angles of a triangle is 180°}
So, Δ AOC is equilateral triangle.
Now, ∠ AOC = ∠ BOD = 60° {Since, they are vertically opposite angles}
Now, in Δ BOD, we have DO = OB. Hence, ∠ D = ∠ B = 60° {As the sum of all the angles of a triangle is 180°}
So, Δ BOD is also an equilateral triangle.
So, DB = BO = DO = 6. (Answer)
