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
Lesechka [4]

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.

Simplify the expression.<br><br>(1/4)^(-3/2)<br><br>Please show how to do the problem.
Vlad [161]
Alright, so since it's to the negative power we essentially have 1/(1/4^(3/2)). After that, we find (1/4)^3=1^3/4^3=1/64 and find the square root of that, which is (sqrt1)/(sqrt64)=1/8. Since the answer is 1/(1/8), we get the answer to be 8

Helga [31]

Answer:

The correct option is D. 2/7

Step-by-step explanation:

Consider the provided information.

There are 8 volunteers including Andrew and Karen, 4 people are to be selected at random to organize a charity event.

We need to determine the probability Andrew will be among the 4 volunteers selected and Karen will not.

We want to select Andrew and 3 others but not Karen in the group.

Thus, the number of ways to select 3 member out of 8-2=6

(We subtract 2 from 8 because Andrew is already selected and we don't want Karen to be selected, so subtract 2 from 8.)

The required probability is:

\dfrac{^6C_3}{^8C_4}=\dfrac{\frac{6!}{3!3!}}{\frac{8!}{4!4!}}\\\\\\\dfrac{^6C_3}{^8C_4}=\frac{20}{70}\\\\\\\dfrac{^6C_3}{^8C_4}=\dfrac{2}{7}

Hence, the correct option is D. 2/7
