If a fair die is rolled 5 times, what is the probability, rounded to the nearest thousandth, of getting at least 2 twos?
ANSWER IS 0.196

Answers

Answer:

0.196

Step-by-step explanation:

The probability of getting at least 2 twos will be 0.66,

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that If a fair die is rolled 5 times, The probability of getting at least 2 twos will be calculated as,

Total outcomes = 5 x 6

Total aoutcomes = 30

Favourable oucomes = 5 x 4 = 20

Probability = 20 / 30

Probability = 0.66

Therefore, the probability of getting at least 2 twos will be 0.66.

Find the volume of a right circular cone that has a height of 13.1 in and a base with a
diameter of 5.7 in. Round your answer to the nearest tenth of a cubic inch.

Answers

Answer:

V≈ 111.43 in³

Step-by-step explanation:

Equation- V = πr² × h/3

1) Divide the diameter in half to make the radius, which equals 2.85 as r.

2) Plug in the radius(r) and height(h) with the correct numbers.

3) Simply solve

V = π(2.85)² × 13.1 ÷ 3

V= 25.52 × 13.1 ÷ 3

V= 334.312 ÷ 3

V= 111.4373+

V≈ 111.43

Dan invests £2200 into his
bank account.
He receives 5% per year simple intrest.
How much will dan have after
2 years?
give your answer to the nearest penny
ühere appropriate

Answers

Answer:

the simple interest here would be $220. the total amount he will receive is $2,420.

Step-by-step explanation:

to find how much interest Dan has, you use the formula,

simple interest = principal * interest rate * time

now we substitute the numbers in.

simple interest = $2,200 * 5% * 2

since the rate is a percentage, we have to convert it into a decimal.

simple interest = $2,200 * 0.05 * 2

let's do this step by step.

simple interest = $2,200 * 0.05 * 2

simple interest = $110 * 2

simple interest = $220

to find out how much Dan will earn after two years, we have to find the total amount by adding the interest and the amount of principal.

since we now know the interest, let's add it by the principal.

$220 + $2,200 = $2,420

Therefore, Dan will have $2,420 after two years.
