Answer: Answer is 16 new releases and 22 classic movies.

Step-by-step explanation:

He'll buy 16 new releases and 22 classic movies.

Let x = number of new releases

Let y = number of classics.

The equation to solve the question will be:

20x + 8y = 500

When x= 16 and y = 22, thus will be:

= 20x + 8y

= 20(16) + 8(22)

= 320 + 176

= 496

Therefore, since this is the number closest to $500, therefore this will be the appropriate number of movies that he can buy.

In conclusion, he'll buy 16 new releases and 22 classic movies.

SD is the standard deviation

xi is each value from the data set

X is the mean of the data set

N is the number of observations in the data set.

It is given that:

The data set:

45, 76, 30, 22, 51, 40, 63, 66, 41

From the formula:

∑(x(i) - X)² = 2463.55

The equation which represents the number of triangles is 1/3 the number of sides is t = (1/3) × s.

Let's denote the number of sides of a polygon as "s" and the number of triangles that can be formed within the polygon as "t."

The equation for the number of triangles being 1/3 the number of sides is:

t = (1/3) × s

This equation states that the number of triangles (t) is equal to one-third of the number of sides (s) in a given polygon.

Hence, the equation which represents the number of triangles is 1/3 the number of sides is t = (1/3) × s.

The factor that provides the basis for the grading of newly diagnosed malignant tumours is degree of differentiation.

The level of differentiation impacts an individual's capacity to control their emotions, thoughts, individuality, and connections to others. The degree of any differential equation can be obtained when it is expressed as a polynomial; otherwise, the degree cannot be defined.

The mechanisms by which immature cells develop into mature cells with particular roles are described in biology. This indicates the degree to which tumour tissue resembles the healthy tissue from which it originated in the context of cancer. Compared to poorly or undifferentiated cancer cells, well-differentiated cancer cells resemble normal cells more and grow and spread more slowly. Tumour grading systems, which vary for each form of cancer, use differentiation.

Answer:

There are no values of x that make this equation true.

Step-by-step explanation:

We know h(x)=[tex]\sqrt{x-3} +5[/tex]

So lets substitute h(x) for 3

3=[tex]\sqrt{x-3}+5[/tex]

We are going to then subtract 5 from each side leaving us with

-2=[tex]\sqrt{x-3}[/tex]

We then need to get rid of the square root, so we will square both sides. which gives us

4=x-3

We then need to subtract 3 from both sides which leaves us with

x=1

However, when you substitute 1 for x into the original equation, you get

h(x)=[tex]\sqrt{-2}+5[/tex]

Which is not equal to 3

Therefore, there are no values of x that make this equation true.

The difference quotient of the function that has been presented to us will turn out to be 5.

In this step, we wish to determine the difference quotient for the function that was supplied.

To begin, keep in mind that the difference quotient may be calculated by:

Lim h->0 [tex]\frac{f(x+h)-f(x)}{h}[/tex]

Now, for the purpose of the function, we need this:

Using exponent properties, the equivalent expression is:

[tex]\frac{y^{18}}{z^{18}}[/tex]

The original expression is:

[tex]\left[\frac{y^{-3}z^5}{z^{-4}y^6}\right]^{-2}[/tex]

When two terms that are divided have the same base and different exponents, we keep the base and subtract the exponents, hence:

[tex]\left[\frac{y^{-3}z^5}{z^{-4}y^6}\right]^{-2} = [y^{-3 - 6}z^{5 - (-4)}]^{-2} = [y^{-9}z^9]^{-2}[/tex]

The negative exponent at the numerator goes to the denominator, hence:

[tex][y^{-9}z^9]^{-2} = \left[\frac{z^9}{y^9}\right]^{-2}[/tex]

The negative outer exponent means that we have to exchange the numerator and denominator, hence:

[tex]\left[\frac{z^9}{y^9}\right]^{-2} = \left[\frac{y^9}{z^9}\right]^{2}[/tex]

Then both numerator and denominator exponents multiply by 2, hence the equivalent expression is:

Yes, it is true the cost of a pumpkin is proportional to the number bought.

We are given the table showing cost of each number of pumpkins. Now, let us analyze the table values;

1) When number of pumpkins is 1, then cost is $4. Thus;

Cost per pumpkin = 4/1 = $4 per pumpkin

2) When number of pumpkins is 2, then cost is $8. Thus;

Cost per pumpkin = 8/2 = $4 per pumpkin

3) When number of pumpkins is 3, then cost is $12. Thus;

Cost per pumpkin = 12/3 = $4 per pumpkin

4) When number of pumpkins is 4, then cost is $16. Thus;

Cost per pumpkin = 16/4 = $4 per pumpkin

In all these rates, we see that the cost rate for pumpkins remains the same. Thus, we can conclude that it is true the cost of a pumpkin is proportional to the number bought.
