Nimfa-mama [501]

Probabilities are used to determine the chances of events

The probability that a randomly selected person with multiple jobs is a male or married is  0.782

<h3>How to determine the probability</h3>

The given parameters are:

Sample size, n = 655

Male = 381

Married = 299

Male and Married = 168

The number of those that are male or married is calculated as:

Male or Married = Male + Married - Male and Married

So, we have:

Male or Married = 381 + 299 - 168

Evaluate

Male or Married = 512

The probability is then calculated as:

p = 512/655

Evaluate

p = 0.782

Hence, the probability that a randomly selected person with multiple jobs is a male or married is  0.782

Briony invests some money. Interest is paid on the money at a rate of 2% per annum for the first year and 1% per annum for the s
nalin [4]

Answer:

Brionny invested £8400.

Step-by-step explanation:

Simple Interest

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

We divide in two intervals, the first year and the second year. We have to know that the amount after the end of the first year is the principal at the start of the second year.

First year:

Amount of 2% interest, during 1 year.

So the interest earned is:

E = P*I*t = P*0.02*1 = 0.02P

The total amount at the end of the first year is:

T = E + P = 0.02P + P = 1.02P

Second year:

We have that:

P = 1.02P

The interest earned is of:

E = P*I*t = 1.02P*0.01*1 = 0.0102P

The total amount is:

T = E + P = 0.0102P + 1.02P = 1.0302P

After two years, the investment is worth £8653.68 How much did Briony invest?

So

1.0302P = 8653.68

P = \frac{8653.68}{1.0302}

P = 8400

Brionny invested £8400.

Prove that√P is irrational for any prime number P​
Luda [366]

Answer:

Step-by-step explanation:

I’m not sure if this is super accurate, but since P is prime, the only factors it has is 1 and itself, meaning that the square root of it will be irrational
