suppose 9 people arrive at a bank at the same time. in how many ways can they line up to wait for the next available teller? a) 40,320 b) 362,880 c) 9 d) 5,040 e) 81 f) none of the above.

Answers

Answer 1

The number of ways in which they can line up to wait for the next available teller is 362880.

What is termed as the permutation?We occasionally want to understand how many different ways we can order a set of items. A permutation is the number of different ways this may be done.

We want to know how many different ways there are to line up 9 people.

We can choose one of the nine people in line to take the first spot. There are just eight people left to select from once we've decided who will fill this position. This means that only eight people can fill this same second position in this line. Now that the first two spots are filled, there are just seven people left to fill the third, and this line of thought can continue until the last spot is filled.

= 9×8×7×6×5×4×3×2×1

= 362880

Thus, the number of ways in which they can line up to wait for the next available teller is 362880.

James is taking out a personal loan from his local bank. if the total loan amount is $2500 at a simple interest rate of 14.99% and in the 1st 4 months he makes only interest payments, how much will he pay in those months total?

Answers

James has to pay an annual interest of 14.99% on $2500 loan.

In decimal:

14.99% = 14.99/100 = 0.1499

The interest of 1st year would be:

0.1499 * 2500 = 374.75 dollars

Monthly interest would be:

374.75/12 = $31.23

If he pays this amount each month for first 4 months, he would pay a total of:

$31.23 * 4 =

Answers

The world record for most selfies taken by a person in one hour is calculated to be 1449.

The world record for the most selfies taken by one person in one hour can be determined by using an algebraic expression.

As 4296 is 51 fewer than three times the World record for the most selfies taken by one person in one hour, we can consider x to be the world record by which we get an algebraic expression as follows;

3x - 51 = 4296

Solving for x;

3x = 4296 + 51

3x = 4347

x = 4347 / 3

x = 1449

Therefore, 1449 is calculated to be the world record for most selfies by one person in one hour.

Work out the total amount of money tom earned on monday

Answers

The money earned by Tom in accordance with his rate is $

In mathematics, comparing two related quantities stated in different units is known as a rate.

If the denominator of the ratio is stated as a single unit of one of these quantities and it is assumed that this number may be changed systematically, the numerator of the ratio expresses the comparable rate of change in the other (dependent) variable (i.e., is an independent variable).Speed, heart rate, and flux are a few examples of rates that are frequently expressed as "per unit of time." Electric field ratios, exchange rates, and literacy rates are a few instances of ratios with a non-time denominator (in volts per meter).

The rate at which he earns is $15 per hour.

He earns over time at 1 1/3 times his wage

Overtime rate = 4 / 3 × 15 = $20

He worked for 11 hours.

Total money earned = 7 hours at rate $15 per hour and 4 hours at rate $20 per hour.

Money earned = 7 × 15 + 20 × 4 = $185

Hence the money earned at that rate is $185.
