Answer: 2< x < 10, closed circle at 2 and 10, line inbetween them
Step-by-step explanation:
Answer:
21.62m
Step-by-step explanation:
first draw the the pipe
second you need know wich is the angle between the pipe and the corner
β=Tan^-1(6/9)=33.7
find the components using tow triangles
a=9/cos(33.7)=10.81m
b=6/sen(33.7)=10.81m
finally sum the leghts
L=10.81+10.81=21.62mm
attached procedure
The percentile rank for 10 will be 10th.
<h3>What is percentile rank?</h3>
The percentile rank of a particular score in statistics refers to the percentage of scores in the frequency distribution that are smaller than that score.
Percentile rank = [(Number of values below x) + 0.5]/ total number of values * 100
For 10,
Percentile rank = {[0 + 0.5]/5} x 100 = 10th
For 15,
Percentile rank = ([1 + 0.5]/5) x 100 = 30st
For 19,
Percentile rank = [2 + 0.5]/5 x 100 = 50th
For 23,
Percentile rank = [3 + 0.5]/5 x 100 = 70th
For 30,
Percentile rank = [4 + 0.5]/ 5 x 100 = 90th
The percentile rank for 10 will be 10th.

Dont mind the sign until fourth step
First step: find divisibles of 90
1,2,3,5,6,9,10,15,18,30,45,90
Second step:find the pairs
1*90,2*45,3*30,5*18,6*15,9*10
Third step: find which one has a difference of 5
None of them is (expand this question more so i can help you)
