Step-by-step explanation:

A statistics teacher was interested in the relationship between the number of days students waited to start a project and the score that project received (out of 100 points). Information was collected on several students and was used to obtain the regression equation ŷ = –3.64x + 96.5, where x represents the number of procrastination days and ŷ is the predicted grade. Which statement best describes the meaning of the y-intercept of the regression line?

AWhen the grade is 0, the predicted number of procrastination days is 0.
BWhen the grade is 0, the predicted number of procrastination days is 96.5.
CWhen the number of procrastination days is 0, the predicted grade is 3.64 points.
DWhen the number of procrastination days is 0, the predicted grade is 96.5 points.

Answers

Answer:

The best option is: When the number of procrastination days is 0, the predicted grade is 96.5 points.

Option D is correct option.

Step-by-step explanation:

The regression equation given is: [tex]y= -3.64x + 96.5[/tex]

where x represents the number of procrastination days and ŷ is the predicted grade.

Which statement best describes the meaning of the y-intercept of the regression line?

First we need to identify what is y-intercept in regression line.

The y-intercept of the regression line is the value of output y when x is 0.

So, when x = 0, the value of output is y-intercept

So, if x = 0

we get:

[tex]y= -3.64x + 96.5\\y= -3.64(0) + 96.5\\y=0+96.5\\y=96.5[/tex]

So, the best option is: When the number of procrastination days is 0, the predicted grade is 96.5 points.

Option D is correct option.

Answer:

t = 54m + 160

Step-by-step explanation:

Input = m

Output = t

Equation of the function in slope-intercept form, is represented as t = km + b

Where,

k = slope/rate of change

b = y-intercept

Using two pairs, say, (2, 268) and (3, 322):

[tex] slope(j) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{322 - 268}{3 - 2} = \frac{54}{1} = 54 [/tex]

k = 54

Find b, by substituting m = 2, t = 268, and k = 54 into t = km + b.

Thus:

268 = (54)(2) + b

268 = 108 + b

268 - 108 = b (subtraction property of equality)

160 = b

b = 160

To find the equation of the function, substitute k = 54, and b = 160 into t = km + b.

Thus:

t = 54m + 160

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 Applicance 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 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

Find the equation of the line passing through the points (3,1) and (7,-7)​

Answers

Answer:

y = -2x + 7

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the point (3,1) and (7,-7), calculate the slope:

[tex]\displaystyle m=\frac{-7-1}{7-3}[/tex]

[tex]\displaystyle m=\frac{-8}{4}=-2[/tex]

m = -2

No w we use any of the given points: (3,1) and substitute in the equation of the line:

y - 1 = -2 ( x - 3 )

Multiplying:

y - 1 = -2x + 6

Adding 1:

y = -2x + 7
