Pavlova-9 [17]2 years ago
4 0

Using previously given equation, the estimate of the GPA of a student who studies for 15 hours a week is; 3.1

<h3>How to predict an equation?</h3>

The equation here is probably a "best fit" equation based upon given data which is GPA versus the number of hours of study per week.

Now, the equation of best fit is given as;

y = 0.149x + 0.89

Thus, if the number of study hours of interest is 15, then the GPA is;

GPA =  0.149(15) + 0.89

GPA = 3.1

If a perfectly competitive firm is a price taker, then
4vir4ik [10]

If a perfectly competitive business firm is a price taker, then: A. pressure from competing firms will force acceptance of the prevailing market price.

<h3>What is a perfectly competitive market?</h3>

A perfectly competitive market can be defined as a type of market that is typically characterized by many buyers and sellers of homogeneous products, and there is free entry and exit in the market.

<h3>What is a price taker?</h3>

A price taker can be defined as a business firm that is operating in a perfectly competitive market and is generally required to take the prevailing market price for its homogeneous product.

In this context, we can infer and logically deduce that pressure from other competing business firms would force acceptance of the prevailing market price when a perfectly competitive business firm is a price taker.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti
nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that  lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn  is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1

For the slope of ln:

m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\

For the slope of mn:

m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\

  • If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

  • To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2

Since no product results in -1, hence δlmn is NOT a right triangle showing that  Lydia's assertion is incorrect
