Compare the slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.
Tcecarenko [31]

Answer:

The slope of f(x) is equal to the slope of g(x).

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope of the function f(x)

we have the points

(0,-1) and (3,1)

substitute in the formula

m=\frac{1+1}{3-0}

m_1=\frac{2}{3}

step 2

Find the slope of the function g(x)

take two points of the given table

(0,2) and (3,4)

substitute in the formula

m=\frac{4-2}{3-0}

m_2=\frac{2}{3}

step 3

Compare the slopes

m_1=m_2

therefore

The slope of f(x) is equal to the slope of g(x).

The revenue function for a bicycle shop is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x)=200−0.4x is
amid [387]

Answer:

maximum revenue is 25000

Step-by-step explanation:

The revenue function for a bicycle shop is given by R(x)=x⋅p(x)

Given p(x)= 200-0.4x

R(x)=x \cdot p(x)

Plug in p(x) in R(x)

R(x)=x \cdot 200-0.4x

R(x)=200x-0.4x^2

Now find out the vertex using formula x=-b/2a

a= -0.4, b=200

x=\frac{-b}{2a} =\frac{-200}{2(-.4)} =250

Plug in 250 for x  in R(x)

R(x)=200x-0.4x^2

R(x)=200(250)-0.4(250)^2=25000

So maximum revenue is 25000

A study will be conducted to investigate whether there is a difference in the mean weights between two populations of raccoons.
enyata [817]

Answer:

<h2>In this case,the answer would be option d) given in the answer choices or options or  A two-sample t-test for a difference between population means.</h2>

Step-by-step explanation:

  • In Statistics,a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise.
  • The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means.
  • In this case,the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.
