1.The measure of center that is most appropriate for this situation is the MEDIAN. This is because, one of the number given is an outlier, that is, it is much greater than the rest of the given numbers. If the mean of the number given is calculated, it will be discovered that the mean value obtained is higher than most of the scores in the data set, thus,the mean is not a suitable measure of central tendency in this case.
2. To find the median of the given numbers, arrange them in a descending order and add the two numbers in the middle then divide the value by 2.
That is, 0, 0, 1, 1, 2, 2, 2, 14.
The two numbers in the middle is 1 and 2.
 Median = [1 + 2] / 2 = 3/2 = 1.5
Therefore, the median is 1.5

Use the formula d=rt to find the distance a long distance runner can run at a rate of 9 1/2 miles per hour for time of 1 3/4 hou
eduard

d=rt

r = 9  1/2  as an improper fraction   (2*9 +1)/2 = 19/2

t = 1 3/4  as an improper fraction (4*1+3)/4 =7/4

d=rt

d = 19/2* 7/4 = 133/8

8 goes into 133 16 times with 5 left over

16 5/8 miles

Solve the equation –4 In(6x) = 2.<br> O A. 0.101<br> B. 0.275<br> C 3.639<br> D. 67.238
EastWind [94]

Isolate the variable using algebraic manipulation.

-4 ln(6x)=2

ln(6x)=-\frac{1}{2}

6x=e^{-\frac{1}{2}}

x=\frac{e^-\frac{1}{2}}{6}

x=0.101

Hope this helps.

頑張って!
