Answer:
8x^2-22x+15
Step-by-step explanation:
Multiply them together
Answer:
There are many, many, different expressions equivalent, but if you distribute them together you come up with:
8x² - 22x + 15
Step-by-step explanation:
When distributing (4x–5) (2x-3) we should end up with four values, and then add them together.
[] The outside numbers of 4x and -3
-> 4x * -3 = -12x
[] The inside numbers of -5 and 2x
-> -5 * 2x = -10x
[] The left numbers of 4x and 2x
-> 4x * 2x = 8x²
[] The right numbers of -5 and -3
-> -5 * -3 = 15
Now we can add them together;
-12x + -10x + 8x² + 15
8x² - 22x + 15

The superintendent of a large school district wants to estimate the percent of district residents who support the building of a new middle school. To gather data, the superintendent will select a random sample of district residents.Which of the following is the most appropriate method for creating such an estimate? *
A one-sample z -interval for a sample proportion
A two-sample z -interval for a difference between population proportions
A two-sample z -interval for a population proportion
A one-sample z -interval for a difference between population proportions
A one-sample z -interval for a population proportion
According to the hypothesis test, the option that gives the most appropriate method for creating such an estimate is:
A one-sample z-interval for a population proportion.
What is the hypothesis test?He will test if there is enough support to build a new middle school, that is, if the population proportion that supports the building of a new middle school is greater than a threshold.
Only one sample is taken from the district residents, hence the correct option is:
A one-sample z-interval for a population proportion.

Is Triangle M'S'V' a reduction or an enlargement of the original Triangle MSV?
Answer:
Reduction
Step-by-step explanation:
In this problem, there are 2 triangles: the solid lines represent the preimage and the dotted lines represent the image. All of the vertices of the dotted lines are inside the solid line. This means that the preimage is larger than the image. If the preimage is larger, then a reduction has occurred.
There are 2 ways to tell that this is a reduction. The simplest is to just say that the image is inside the preimage and therefore smaller. More mathematically, you could also see that all of the coordinate pairs are closer to the origin by a scale factor of 2/3. Thus, the triangle must be smaller and reduced.

The volume of a rectangular solid is given by the polynomial 3x^4-3x^3-33x^2+54x. If the length of the solid is 3x and the width of the solid is x-2 Find the height?
Answer:
[tex]\mathsf{height}=x^2+x-9[/tex]
Step-by-step explanation:
Volume of a cuboid = L x w x h
(where L is the length, w is the width and h is the height)
[tex]\implies \mathsf{height=\frac{volume}{width \times length} }[/tex]
Given:
[tex]\mathsf{volume}=3x^4-3x^3-33x^2+54x[/tex]
[tex]\mathsf{width}=x-2[/tex]
[tex]\mathsf{length}=3x[/tex]
[tex]\implies \mathsf{height}=\frac{3x^4-3x^3-33x^2+54x}{3x(x-2)}[/tex]
Factor expression for volume
Factor out common term [tex]3x[/tex]: [tex]3x(x^3-x^2-11x+18)[/tex]
Factor [tex]x^3-x^2-11x+18[/tex]: [tex]3x(x-2)(x^2+x-9)[/tex]
[tex]\implies \mathsf{height}=\frac{3x(x-2)(x^2+x-9)}{3x(x-2)}[/tex]
Cancel the common factors [tex]3x(x-2)[/tex]:
[tex]\implies \mathsf{height}=x^2+x-9[/tex]

Suppose you have 3 idenitcal cookies and 4 identical candy bars and wish to distribute them to 10 different friends. Assuming no one may have more than one item, how many different distributions are possible
Using the combination formula, it is found that 120 distributions are possible.
In this problem, the order in which the items are distributed is not important, hence the combination formula is used to solve this question.
What is the combination formula?[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem, 7 items will be given to a set of 10 people, hence:

Leo wants to buy some shoes. He found the shoes at three different stores for a price of $35.
The final price of store X-
As store X is offering 15% off the price of the shoes and the price of shoes is $35. Thus the selling price of store X is,
[tex]P_x=35-35\times\dfrac{15}{100}\\P_x=35-5.25\\P_x=29.75[/tex]
As store Y is offering $5 off the price of the shoes and the price of shoes is $35. Thus the selling price of store Y is,
[tex]P_y=35-35\times\dfrac{5}{100}\\P_y=35-1.75\\P_y=23.25[/tex]
As store Z is offering a 1/5 discount off the price of the shoes and the price of shoes is $35. Thus the selling price of store Z is,

The weight of the apples is a function of the number of apples. a
Answer:
MY ANSWER IS THIS. IS. A. QUIZ.
Step-by-step explanation:
The cost of the apples is a function of their weight is true about the functional relationship shown in the graph. Correct option is c.
In the graph, the horizontal axis represents the weight (in pounds) of the apples, and the vertical axis represents the cost (in dollars) of the apples. As the weight of the apples increases, the cost also increases. This relationship shows that the cost of the apples is dependent on their weight, making it a functional relationship of "cost as a function of weight."
