James takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A hamster we

ighs 3 pounds and costs $3.50 per week to feed, while a Chihuahua weighs 4.8 pounds and costs $6.20 per week to feed. Using weight as the explanatory variable, what is the slope of the line between these two points? Answer choices are rounded to the nearest hundredth.

Answer:

The slope of the line between these two points is 1.50.

Step-by-step explanation:

The general form of the regression line is:

y=mx+c

Here,

<em>y</em> = dependent variable

<em>x</em> = independent variable

<em>m</em> = slope

<em>c</em> = intercept.

The formula to compute slope using two-point method is:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case the dependent variable is the cost per week to feed and independent variable is the weight of the hamster.

The two points are:

(<em>x</em>₁, <em>y</em>₁) = (3, 3.50)

(<em>x</em>₂, <em>y</em>₂) = (4.8, 6.20)

Compute the slope as follows:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

    =\frac{6.20-3.50}{4.8-3}

    =\frac{2.7}{1.8}

    =1.50

Thus, the slope of the line between these two points is 1.50.

find the scale, k, of H(3,4) if H'(9,12) after going through the transformation (x,y) ---&gt; (kx,ky) centered at the origin
stiks02 [169]

The value of scale k is 3

Step-by-step explanation:

In order to find the scale , we can either divide the coordinates of H' by the original point or compare both the points to find the original ordered pair.

Given

H(3,4)

H'(9,12)

The coordinates of H are multiplied with some integer k to form H'

So,

<u>For x-coordinate:</u>

3k = 9

k = 9/3 = 3

<u>For y-coordinate:</u>

4k = 12

k = 12/4 = 3

Hence,

The value of scale k is 3

3 over 4 open parentheses 1 half x space minus space 12 close parentheses space plus space 4 over 5
lesantik [10]

For this case we have the following expression:

\frac {3} {4} (\frac {1} {2} x-12) + \frac {4} {5}

Rewriting the expression we have:

We apply distributive property to the terms of parentheses:

\frac {3} {8} x- \frac {36} {4} + \frac {4} {5}\\\frac {3} {8} x-9 + \frac {4} {5}\\\frac {3} {8} x- \frac {41} {5}\\

Answer:

\frac {3} {8} x- \frac {41} {5}

If 6 people want to share a 30 pound bag of beans equally by weight how many pounds of beans should each person get? Between wha
sertanlavr [38]

Answer:

The 6 people would each get 5lb. of beans. 5 lies between 4 and 6.

Step-by-step explanation:

To get the answer to this problem, all you have to do is divide the total pounds of beans by how many people there are. 30 ÷ 6= 5, so each person would get 5 pounds. Since 5 comes between 4 & 6, you can use that as your answer.
