Answer:

False

Step-by-step explanation:

3 out of 2 can be represented as 3/2 which simplified is 1.5, This statement is saying that out of 1 person, 1.5 of them have trouble with fractions which isn't possible because 2/2 is the whole amount, so anything above 2/2 is simply not possible <u>in this scenario</u>

Compute the present value of $9,000 paid in four years using the following discount rates: 4 percent in year 1, 5 percent in yea

juin [17]

The sum would amount to $10,527.75 after the end of 4 years.

Step-by-step explanation:

The Problem pertains to compounding interest with varying rates over the years. Our approach to solve the problem would be in a chronological fashion starting with the 1st year

Principal- $ 9000

Rate interest= 4%

Time period would be 1 year since the interest are considered for successive years.

We know the formulae- Amount= Principal (1+rate/100) ⁿ

Where “n”= time period= 1 in all cases

⇒Amount after 1st year at 4% rate= 9000(1+4/100)

9000*104/100= $ 9360

This amount would serve as Principal for 2nd year

⇒Hence, Amount for 2nd year at 5% rate= 9360(1+5/100)

9000*105/100= $ 9828

⇒Similarly, Amount for 3rd year at 4% rate= 9828(1+4/100)

=9828*104/100= $ 10,221.12

⇒Amount for the last year at 3% rate= 10,221.12(1+3/100)

=10,221.12*103/100= $ 10527.75

Hence the present value of the amount is $ 10527.75 after the end of 4 years.

Tonya runs 8 kilometers in 60 minutes.At this rate,how long it take her to run 2 kilometers

Setler79 [48]

15 Minutes

You have 8 km in an hour.

Divide all that by two and you'll have 4 km in 30 mins.

Then divide by two again to end up with 2 km in 15 mins.

You could alternatively divide by four from the beginning, but I find this easier.

Which is a factor of x2 + 5x − 24?

Ad libitum [116K]

Answer:

(x−3)(x+8)

Step-by-step explanation:

The middle number is 5 and the last number is -24.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 5

Multiply together to get -24

Can you think of the two numbers?

Try -3 and 8:

-3+8 = 5

-3*8 = -24

Fill in the blanks in

(x+_)(x+_)

with -3 and 8 to get...

(x-3)(x+8)

The probability of choosing a penny from the 1980s from the bag of pennies without looking is 3/40 . Which term best describes t

erik [133]

Answer: Unlikely

Step-by-step explanation:

Given: The probability of choosing a penny from the 1980s from the bag of pennies without looking= $\frac{3}{40}=0.075$

We know that the probability of any event lies between 0 and 1.

If probability of occurring event is 0 then the event is impossible.
If probability of occurring any event is 1 then the event certain.
If probability of occurring any event lies between 0.5 and 1 then the event is said to be likely.
If probability of occurring any event lies between 0 and 0.5 then the event is said to be unlikely.

Since, 0.075 lieas between 0 and 0.5, therefore the event is said to be unlikely.
