The exponential growth model for the future population is given as [tex]y = 1500(1.1)^{t}[/tex]   and the student population after 7 years is 2923.06.

The general expression for the exponential growth is given as :

                       [tex]y = a(1+r)^{t}[/tex]

where, a  = initial amount or current student population of Philadelphia

           r = rate

           t = time in years.

According to the question we have been given that

           a = 1500

           r = 0.1

putting the required values in above equation we get

                   [tex]y = 1500 (1+0.1)^{t}\\y = 1500(1.1)^{t}[/tex]

Hence the exponential growth model for the future population is given as :

                      [tex]y = 1500(1.1)^{t}[/tex]

For the population in 7 years is :

                      [tex]y = 1500(1.1)^{7}\\y = 1500*1.949\\y = 2923.06[/tex]

hence the student population after 7 years is 2923.06

The value of the probability is 0.0714.

According to the statement

We have to find that the students' favorite color was red.

So, For this purpose, we know that the

Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.

From the given information:

A bag 2 contains 2 red marbles, 2 green marbles, and 4 blue marbles.If we choose a marble, then another marble without putting the first one back in the bag.

Then

A bag contains 2+2+4=8 marbles in total.

We have to search out the probability of the subsequent events:

1. we've to settle on a red marble from the bag that contains 8 marbles in total, 2 of them are red

2. we've to decide on a green marble from the bag that contains 7 marbles in total, 2 of them are green.

The probability of the primary event to happens is:

P(one) = 2/8 = 1/4.

The probability of the second event to happen is:

P(two) = 2/7

The probability of both events to happen is:

P = P(one) * P(two)

P = 1/4 * 2/7

P = 1/14

P = 0.0714.

So, The value of the probability is 0.0714.

Answer:

  25 and 7

Step-by-step explanation:

You want to find two numbers with a sum of 32 such that the larger is 3 less than 4 times the smaller.

Let s represent the smaller number. Then the larger is (4s-3) and their sum is ...

  s +(4s -3) = 32

Collect terms to get ...

  5s -3 = 32

  5s = 35 . . . . . . . add 3

  s = 7 . . . . . . . divide by 5

  4s-3 = 28-3 = 25 . . . . the larger number

Answer:

10 as 9 hundreds is 9 thousand.

Step-by-step explanation:

The digit is 9 thousand which can be written as 9,000

It can also be written as,

9,000 = 9 x 1000

or ,9,000 = 9 x 10 x 100

So, to require 9 hundreds multiply 9 by 100 in the expression above

9,000 = 10 x 900

And so Ten as 9 hundreds are 9 thousand.

As the yard for the pet is square shaped with area 100 sq. ft, length of each side is given by  

             [tex]\sf side =\sqrt{area}\\\\ side = \sqrt{100}[/tex]

                    = 10 ft

Perimeter:

          Perimeter of square = 4 *side

The cost of the lab per hour is $25.

Here we know that they charged a total of $249.75, and the cost in parts was $181, then the cost in labor is:

$249.75 - $181 = $68.75

And we know that they worked for 2.75 hours, the cost per hour is given by the quotient between the cost in labor and the number of hours, then we can get:

$68.75/2.75 = $25

So we can see that the cost of the lab per hour is $25.

Answer:

4 7/15

Step-by-step explanation:

To subtract two fractions we need to have them have the same division by, which means the lower part of the fraction needs to be the same. To do that we would need to find a common denominator between 3 and 5, a number that can be both divided by 3 and 5. To figure common denominator for 5 and other nimbery just multiply the other number by 5: 3*5=15. so now we need to multiply both fractions by a number to get lower part to 15, so 4*3/5*3=12/15 and 1*5/3*5=5/15. Now we have 6 12/15 - 2 5/15 = 4 7/15.

Answer:

14 Videos

Step-by-step explanation:

Let x be the number of videos rentable.

From the information given from the question, we know that:

Case A: Non-members

Cost to rent videos = $4x

Case B: Members

Cost to rent videos = $(21 + 2.5x)

So given from the question, we can use:

4x = 21 + 2.5x to solve for x.

[tex]4x = 21 + 2.5x \\ 4x - 2.5x = 21 + 2.5x - 2.5x \\ 1.5x = 21 \\ x = \frac{21}{1.5} \\ = 14[/tex]

A function N(t) to represent the number of members in the scheme after t days is given as:

N(t) = 2ˣ (where, x = 0, 2, 4 , 6 ....)

For the given statements in the question;

The scheme starts with 1 person who recruits 4 person.

Then, the next 4 person will their respective 4 recruits.

Thus, the sequence will become;

1, 4, 16, 64.....

Thus sequence can be written as;

2⁰, 2², 2⁴, 2⁶,.....

Thus, in the function form it represents;

2ˣ (where, x = 0, 2, 4 , 6 ....)

Thus, a function N(t) to demonstrate the total number of scheme members after t days is;

N(t) = 2ˣ (where, x = 0, 2, 4 , 6 ....)

The difference between 9493 take away 2324

Difference in math is the result of one of the important mathematical operations, which is obtained by subtracting two numbers. It tells us by how much a number differs from the other. The aim of finding the difference in math is to tell how many numbers lie between the two given numbers.

Set difference is a generalization of the idea of the complement of a set and as such is sometimes called the relative complement of T with respect to S. The symmetric difference between two sets S and T is the union of S – T and T – S.

Based on the conditions, formulate :

Let us assume,

The difference between value = x

We can write,

x = 9493 -  2324

Calculate the sum or difference,

x = 7169.

Probability is the measure of how likely an event is to occur. Many events are impossible to predict to absolute certainty. We can only predict the possibility of an event occurring, i.e. how likely it is to occur, using it.

The formula for probability is;

Probability(event) = favourable outcome/ total outcome

Now, as per the given question;

There are 27 papers put in a hat numbering from 1 to 27.

If Tito took a loan of $10000 from a bank to be repaid within 4 years, at 12% Simple interest per annum, then, he will have to pay overall $4800 as interest to the bank over 4 years and a total payment of $14800 at the end of the 4th year to repay and close off the loan.

As per the question statement, a bank charges 12% Simple interest per annum on cash loans to its clients and Tito took a loan of $10000 from the same bank to be repaid within 4 years.

We are required to calculate the overall interest Tito has to pay to bank if he repays and closes the loan at the end of 4th year, and also to calculate the total payment required to repay and close off the loan at the end of the 4th year.

To solve this question, we need to know the formula to calculate the interest amount in case of simple interest which goes as

Interest (I) [tex]=(\frac{P*R*T}{100} )[/tex]

where, "P" = Principle amount of Loan,

"R" = Rate of simple interest charged on the principle per annum, and

"T" = Time period within which, the loan is to be repaid.

Here, (P = 10000), (R = 12%) and (T = 4). Then, the overall interest Tito will have to pay at the end of 4th year  = [tex](\frac{10000*12*4}{100}) = (100*12*4)=(48*100)=4800[/tex]

And total amount to be paid to repay and close of the loan at the end of 4th year will be = $[4800 + 10000] = $14800.
