Answer:

a) 22 taxis

b) 4 students

Step-by-step explanation:

150 ÷ 7 = 21 with a remain of 3.

You need one more taxi for those 3 students.

21 + 1 = 22

You need to hire 22 taxis.

Check:

7 × $21\frac{3}{7}=150$

____________________________________________________________

7 - 3 = 4

If you had 4 more students, then all of the taxis would be full.

Check:

150 + 4 = 154

7 × 22 = 154

A.Calculate the mean,median and mode.(3 points each) 1.)1,2,3,4,5 2.)2,3,4,5,6,6 3.)6,7,5,4,5,6,2,5

zlopas [31]

Answer:

Step-by-step explanation:

1.)1,2,3,4,5

mean=sum of all values/number of values

=1+2+3+4+5/5

=15/5

mean=3

Mode :

In the given data, no observation occurs more than once.

Hence the mode of the observations does not exist, means mode=0.

Median

1,2,3,4,5

Middle value is 3 so the median is 3.

2.)2,3,4,5,6,6

mean=sum of all values/number of values

=2+3+4+5+6+6/6

=26/6

mean =4.33

Mode

is that value of the observation which occurs maximum number of times so here mode is 6.

Median

2,3,4,5,6,6

4+5/2

9/2

median=4.5

3.)6,7,5,4,5,6,2,5

mean=sum of all values/number of values

=6+7+5+4+5+6+2+5/8

=40/8

mean =5

Mode

is that value of the observation which occurs maximum number of times so here mode is 5

Median

2,4,5,5,5,6,6,7

5+5/2

10/2

median=5
