Anni [7]

we know that

1) Before the missed test

a) mean=[82+100+96+90+91]/5=459/5------> 91.8

b) median

82,90,91,96,100-------> the median is 91

2) After adding the 0 test score

a) mean=[82+100+96+90+91+0]/5=459/6------> 76.5

b) median

0,82,90,91,96,100-------> the median is [90+91]/2-----> 90.5

therefore

a) After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data-------> is true

b) After adding the 0 test score, the mean would be affected-----> is true

c) After adding the 0 test score, the median would be the most appropriate measure of center to describe the data-----> is false

d) Before the missed test, Eva’s median score was 96-----> is false

e) Before the missed test, Eva’s median score was 91------ is true

f) Before the missed test, Eva’s mean score was 91.8-----> is true

➷The answer is 18 hours.

Explanation: If you look carefully, you can see that the answer is the second condition as well. If one pipe did half, then the other pipe took over and that took 18 hours, that means that it equals one pipe filling the pool continuously by itself. :)

Charlotte is running at a rate of 9\,\dfrac{\text{km}}{\text{h}}9 h km 9, start fraction, start text, k, m, end text, divided

OverLord2011 [107]

Answer:

2.5 meters per second

Step-by-step explanation:

Given,

The speed of Charlotte = 9 km/h

That is, the distance covered in 1 hour = 9 km,

∵ 1 km = 1000 m

So, the distance covered in 1 hour = 9000 m,

∵ 1 hour = 60 minutes and 1 minute = 60 seconds,

⇒ 1 hours = 3600 seconds,

∴ The distance covered in 3600 seconds = 9000 m,

⇒ Distance covered in 1 second = $\frac{9000}{3600}$ = 2.5 m,

Hence, his/her speed = 2.5 meters per second
