On a & b i will mark brainliest

A.) Hobbs:

We know that the dependent variable goes on the y axis and that the independent variable goes on the x axis. In this case, the cost changes according to the number of hours, so x = hours and y = cost. SInce it states that both of the relationships are linear, this means that we should look for a slope equation: y = (slope) * x + (y intercept).

We begin with y2 - y1/x2 - x1. In this case, the x value changes by a value of 0.5 and the y value changes by 17, making our slope 17/0.5, or 34.

Now that we know the m value, write down the equation y = 34x + b, and plug in the values you already know. For instance, if we use the first pair:

25 = 34 * 0.5 + b

25 = 17 + b, which means b = 8. Your equation for this is y = 34x + 8.

McGee:

Using the same method, 144 - 80/4 - 2 = 64/2 = 32.

y = 32x + b

80 = 32 * 2 + b, so b = 16.

Now let's plug in the x values.

Hobbs: y = 34(3) + 8, so y = $110

McGee: y = 32(3) + 16 = $112

Therefore, the customers should go to Hobbs for 3 hour mule rides, since it's less expensive.

B.) Yes. this would affect the answer to part A. Since the x value has changed, the y value would also have to change for the equation to be true. FOr instance:

34(5) + 8 = $178

32(5) + 16 = $176

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
