Answers

Answer:

2,6

Step-by-step explanation:

Answer:

1. (2,6)

2. C

3. B

Step-by-step explanation:

y = - 2x + 10

y = x + 4

SInce the two equation both equal y, we can said they are equal.

- 2x + 10 = x + 4

      - 10        - 10

- 2x = x - 6

- x     - x

- 3x = - 6

/-3        /-3

x = 2

Then we plug the x value into the equations and we will get the point that intersects y=-2x+10 and y=x+4.

- 2(2) + 10 = 2 + 4

- 4 + 10 = 6

6 = 6

This is true since both sides are equal.

The point that intersects y=-2x+10 and y=x+4 is (2,6).

2. If the two lines y1=−12x+5 and y2=2x+5 were to be graphed, what would their intersection point represent?

C) Their intersection point is the only point where different inputs into both functions yield the same output.

Ex: y=-2x+10 and y=x+4 both have the same solution which is (2,6).

3. Given an equation y=−13x+5, explain the steps for using slope-intercept form to graph this equation.

y = - 1/3x + 5

y = - 1/3(0) + 5

y = 5

Point: (0,5)

Slope: - 1/3

Rise over run (y/x) so up 3 and left 1.

B) Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point.

Use this information and a 5% level of significance to determine if National Applicance should reject the batch.

Answers

Complete Question

The National Appliance Company makes refrigerators. One of its suppliers, the Exeter company, produces plastic shelves for the refrigerators and ships them in large lots. The National Appliance Company requires that the percentage of the plastic shelves that are defective be no more than 10%. If more than 10% are defective, the Prime Factor Company will reject the lot. To test this, the National Appliance Company randomly selects 573 of the shelves and has them inspected. It turns out that 70 are defective. Use this information and a 5% level of significance to determine if National Appliance should reject the batch.

Answer:

  The decision rule is  

Reject the null hypothesis  

The conclusion is  

There is no sufficient evidence to conclude that  proportion of defective shelf is less than or equal to 0.10  hence the National Appliance Company should reject that batch of shelfs

Step-by-step explanation:

From the question we are told that

    The population of defective plastics is  [tex]p = 0.10[/tex]

    The sample size is  n = 573

    The number of shelf that are defective is  k =  70  

     The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the sample proportion is mathematically represented as

           [tex]\^ p = \frac{k}{n}[/tex]

=>       [tex]\^ p = 0.1222[/tex]

The null hypothesis is [tex]H_o : p \le 0.10[/tex]

The  alternative hypothesis is  [tex]H_a : p > 0.10[/tex]

Generally the test statistics is mathematically represented as

            [tex]z = \frac{\^ p - p }{ \sqrt{\frac{p (1 - p)}{ n } } }[/tex]

=>          [tex]z = \frac{ 0.1222 - 0.10 }{ \sqrt{\frac{0.10 (1 - 0.10 )}{ 573 } } }[/tex]

=>          [tex]z = 1.77[/tex]

From the z table  the area under the normal curve to the right  corresponding to  1.77   is

       [tex]p-value = P(Z > 1.77 ) = 0.038364[/tex]

From the question we are told that  [tex]p-value < \alpha[/tex] hence

  The decision rule is  

Reject the null hypothesis  

The conclusion is  

  There is no sufficient evidence to conclude that  proportion of defective shelf is less than or equal to  0.10  hence the company should reject theat batch of shelfs

Solve 5 (y + 10) = 7y

Answers

Answer:

25

Step-by-step explanation:

Hi there! In order to solve this equation, all you have to do is distribute the 5 to the (y+10) and then shift like terms. Once you do that, you would get 5y+50=7y, and then you subtract the 5y from the 7y in order to get the 50 by itself. That would get you 2y, and from there, you just simply divide the value of 50 by 2y- getting you to 25 as the value of y. I hope this helped! <3 (Please mark as branliest if I got this right!)

Answer:

y = 25

Step-by-step explanation:

Distribute 5 (y+ 10) to get

5y + 50 = 7y

subtract the 5y from both sides to get

50 = 2y

divide the 2 from 2y on both sides to get

25 = y, or y = 25

4.25 in^2
8.5 in^2
18.0625 in^2
72.25 in^2

Step-by-step explanation:

72.25 in^2

The minimum possible area of each square cardboard piece that is used to produce circular drink coasters is 72.25 in².

What is the equation of a circle?

The equation of the circle is the equation that is used to represent the circle in the algebraic equation form with the value of the center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here (h,k) is the center of the circle, and (r) is the radius of the circle.

A company produces circular drink coasters. the equation which represents the size of a coaster is,

[tex]x^2+y^2=18.06[/tex]

The units are in inches. This equation can be written as,

[tex]x^2+y^2=(280/16)[/tex]

[tex]x^2+y^2=(17/4)^2[/tex]

Compare it with the equation of the circle, we get,

h=0

k=0

r=17/4 inch

The radius of the circular coaster is 17/4. Its diameter of it is,

[tex]d=2\times \frac{17}{4}\\ \\d=\frac{17}{2}[/tex]

Now, each coaster is cut from a square piece of cardboard. The diameter of the circular coaster will be equal to the side of the square piece of cardboard.

a=d=17/2 inch

The area of the square is the square of its side. Thus, the area of a square piece of cardboard is,

A=a^2

A=(17/2)^2

A=75.25inch^2

Thus, the minimum possible area of each square cardboard piece that is used to produce circular drink coasters is 72.25 in².
