svetoff [14.1K]

Answer:

Option D. The student is completely incorrect because there is no solution to this inequality.

Step-by-step explanation:

The question is as following:

A student found the solution below for the given inequality.

|x-9|<-4

x-9>4 and x-9<-4

x>13 and x<5

Which of the following explains whether the student is correct?

A. The student is completely correct because the student correctly wrote and solved the compound inequality.

B. The student is partially correct because only one part of the compound inequality is written correctly.

C. The student is partially correct because the student should have written the statements using “or” instead of “and.”

D. The student is completely incorrect because there is no solution to this inequality.

==========================================================

Given: |x-9| < -4

We should know that the out put of modulus always will be greater than or equal to zero.

So, The inequality always will not be true (unlogic condition)

So, There is no solution to this inequality.

The answer is option D

D. The student is completely incorrect because there is no solution to this inequality.

Suppose the linear regression line y = 2.009x - 37.131 predicts a pizza

VARVARA [1.3K]

Answer:

Pizza parlor's profit = $515.344

Step-by-step explanation:

Given that:

Linear regression line for pizza parlor's profit

y = 2.009x - 37.131

x represents the number of pizzas sold

y represent the profit in dollars

Profit for 275 pizzas

Putting x = 275 in given equation

y = 2.009(275) - 37.131

y = 552.475 - 37.131

y = 515.344

Hence,

Pizza parlor's profit = $515.344

andre [41]

$\bold{\huge{\orange{\underline{ Solution }}}}$

$\bold{\underline{ Given :- }}$

Jan purchased 140 shares of stock in ABC company at a price of $18.75 per share
During the next 3 days, the value of share declined by $1.00 , $1.75 and $1.50

$\bold{\underline{ To \: Find :- }}$

We have to find the value of a share of ABC stock at the end of 3 days

$\bold{\underline{ Let's \: Begin :- }}$

According to the question,

Cost of 1 share of ABC company = $18.75

Therefore, 

Cost of 140 shares purchased by Jan in the ABC company

$\sf{ = 140 × 18.75 }$

$\sf{ = 2625\: dollars }$

Now, 

For next 3 days, the value of share declined

$\sf{ = (1 + 1.75 + 1.50)dollars }$

$\sf{ = 4.25 \: dollars }$

Therefore, 

The value of shares after 3 days will be

$\bold{ = }{\bold{\frac{2625 - 4.25}{ 140}}}$

$\bold{ = }{\bold{\frac{ 2620.75}{ 140}}}$

$\bold{\red{ = 18.75\: dollars}}$

Hence, The value of share after 3 days will be $18.75 .
