The officer saves $91.45 per month

~Step-by-step explanation~

Ok this is how I do fractions and its not very good, but it works.

First I divided 6400 by 5, 6, and 7, (I didn't do 3 because you can just multiply the answer to 6 by 2.) the reason I divided these is to see how much 1 part of their fraction is worth. So in total I got 1066.66 (irrational number) for insurance which means I got 2133.32 for his monthly living ( had to multiply by 2). For his car payment I got 1828.57 (I divided and then multiplied by 2) and for his rent I got 1280. I added these all together to get the total he spends each month which was 6308.55, and I subtracted that from 6400 to figure out that he puts $91.45 in his savings account

The answer is R91.43.

Step-by-step explanation:

Monthly salary of the worker = R6400

The monthly expenses are 1/5 for rent that is $\frac{1}{5}\times6400= 1280$

The car payment is 2/7 that is $\frac{2}{7}\times6400= 1828.57$

The insurance is 1/6 that is $\frac{1}{6}\times6400= 1066.67$

Few other monthly living expenses are 1/3 that is $\frac{1}{3}\times6400= 2133.33$

We will total these values:

1280+1828.57+1066.67+2133.33=6308.57

So, the amount that is saved per month = 6400-6308.57=91.43

The answer is R91.43.

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.
