Easy, so absolute value makes anything inside into positive
|x|=2
therefor x=-2 or x=2 since it would be made posotive
answer is -2 and 2
Find the mean and median of the data set 3,5,6,2,10,9,7,5,11,6,4,2,5,4
Tanya [424]
Answer:
mean: 5.6 ; median: 5
Step-by-step explanation:
first order them:
2, 2, 3, 4, 4, 5, 5, 5, 6, 6, 7, 9, 10, 11
now we can see that the median is 5 since it's in the middle
and the mean is adding all and dividing by how many numbers we have (AKA 14) so 2+2+3+4+4+5+5+5+6+6+7+9+10+11 = 79 and now we divide 79 by 14 which is:
5.64285714
To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps
<h3><u>Let's</u><u> </u><u>understand</u><u> </u><u>the concept</u><u>:</u><u>-</u></h3>
- Here angle B is 90°
- So
and
Are right angled triangle - So we use Pythagoras thereon for solution
<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
perpendicular=p=8cm
Hypontenuse =h =10cm
According to Pythagoras thereon













BD=BC+CD




- Now in

Perpendicular=p=8cm
Base =b=15cm
- We need to find Hypontenuse =AD(x)
According to Pythagoras thereon
