Ataxi cab costs $1.50 for the first mile and $0.75 for each additional mile which equation could be solved to find how many miles you can travel in a taxi for $10 given that x is the number of additional miles
a| 1.5x + 0.75 = $10
b| 0.75x + 1.5 = $10
c| 1.5x - 0.75 = $10
d| 0.75x - 1.5 = $10

which is the solution of t/2.5 = -5.2

a| t= -13
b| t= -2.08
c| t=2.08
d| t=13

which expression is equivalent to 5x - 30

a| 5(x - 30)
b| 5(x-6)
c| 5x(x-6
d| x(5-30)

in a science experiment the tempature of a substance is changed from 42.f to -54.f at an average rate of -12 degrees per hour over how many hours does the change take place

a| -8 hours
b| 1/8 hours
c| 1 hours
d| 8 hours

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.
