Answer:

Chan is not correct.

The correct equivalent quarterly interest rate is 1.3108% per quarter.

Step-by-step explanation:

Given that Chan deposited money into his retirement account.

The interest was 7% compounded annually.

Let P be the amount invested and F the final amount got after 1 year

If compounded annually,

F = P(1+0.07) = 1.07P

If compounded quarterly, no of quarters = 4

F = $P(1+\frac{7}{100} )^4$

= 1.3108P

Hence equivalent interest rate = 1.3108% and not 2%

How many complete rotations does the minute hand of a clock make as it moves from 12:00 noon to 4:00 p.m.?

Elenna [48]

Answer:

$4\ rotations$

Step-by-step explanation:

we know that

The minute hand of a clock will make one rotation in one hour

$12:00$ noon to $4:00$ p.m is equal to $4\ hours$

by proportion

Find how many rotations will make in $4$ hours

$\frac{1}{1} \frac{rotation}{hour}=\frac{x}{4} \frac{rotation}{hours} \\ \\ x=4\ rotations$

How many integers are there that consist of four digits (from 1000 to 9999) where the first digit is a 5 or an 8 and the third d

Ostrovityanka [42]

Answer:

1600 integers

Step-by-step explanation:

Since we have a four digit number, there are four digit placements.

For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.

For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.

For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.

So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers
