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 negative numbers are the additive inverses of the corresponding positive numbers.integer, whole-valued positive or negative number or 0. The integers are generated from the set of counting numbers 1, 2, 3,…  and therefore the  operation of subtraction. When a counting number is subtracted from itself, the  result's  zero; for example, 4 − 4 = 0.

The measure of angle AEC is 115°.

What are Supplementary angle?

Supplementary angle are those angles whose sum up are 180 degree.

Given that;

Measure of angle AED = 65

The angle AEC is supplementary to the angle AED.

Now, The angle AEC is supplementary to the angle AED.

Hence, ∠ AEC + ∠AED = 180°

Since, Measure of angle AED = 65°

So,  ∠ AEC + ∠AED = 180°

⇒ ∠ AEC + 65° = 180°

⇒ ∠ AEC = 180° - 65°

⇒ ∠ AEC = 115°

Therefore, The measure of angle AEC is 115°.

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.

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:

what graph but domain is the x axis

Step-by-step explanation:

The function f(x)=x+3 belongs to linear category.

For a function to be linear it must have an single variable and also the maximum power to that variable in the equation must be 1.

In a linear variable there is always single value possible in a equation.

In the function also there is only one value at one time but it varies according to the function change.

Here the function f(x)=x+3 will vary as the value of x changes.

For x=1 the value of f(1)=4

For x=2 the value of f(2)=5 and so on

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

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,
