Suppose that in a large metropolitan area, 84% of all households have cable tv. Suppose you are interested in selecting a group
Firdavs [7]

Answer:

0.05606

Step-by-step explanation:

This is a binomial probability distribution problem.

84% of all households have cable TV, thus;

p = 0.84

There are six households from this area, thus; n = 6

Formula for this binomial distribution is;

P(X) = C(n, x) × p^(x) × (1 - p)^(n - x)

We want to find the proportion of groups where at most three of the households have cable TV.

Thus, it's is;

P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

P(X = 0) = C(6, 0) × 0.84^(0) × (1 - 0.84)^(6 - 0) = 0.00001678

P(X = 1) = C(6, 1) × 0.84^(1) × (1 - 0.84)^(6 - 1) = 0.000528

P(X = 2) = C(6, 2) × 0.84^(2) × (1 - 0.84)^(6 - 2) = 0.006963

P(X = 3) = C(6, 3) × 0.84^(3) × (1 - 0.84)^(6 - 3) = 0.04855

Thus;

P(X ≤ 3) = 0.00001678 + 0.000528 + 0.006963 + 0.04855 = 0.05606

A circle has a diameter of 26 units. What is the area of the circle to the nearest hundredth of a square unit.
iris [78.8K]

9514 1404 393

Answer:

  530.93 square units

Step-by-step explanation:

The area of a circle in terms of diameter can be found by ...

  A = (π/4)d²

  A = 3.14159/4×26² ≈ 530.929

Rounded to hundredths, the area of the circle is 530.93 square units.

If the principal is $200 and the interest rate is 4 percent, what is the simple interest earned in one year? Simple interest = P
dem82 [27]
Given:
Principal = 200
interest rate = 4% per annum
term = 1 year

Simple Interest = Principal * interest rate * term
S.I. = 200 * 4% * 1
S.I = 8

Simple interest earned is $8.
