Answer:
8
Step-by-step explanation:
Arranging the data into the increasing order
5.6 6.0 6.4 6.5 6.6 6.8 7.1 7.7 7.8 7.9 8.0 8.2 8.8 8.8 9.3
73n/100=73*15/100=10.95 is not an integer
So, the 73rd percentile is
P73= weight of (73n/100)+1
P73= weight of observation (10+1)
P73=weight of 11th observation
P73=8.
The weight that represents the 73rd percentile is 8.
Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
Answer: 60°
Step-by-step explanation:
- the two angles created by CD and EF are vertical angles so they are equal
- one angle is 30° so the other one is 30° and it splits an existing 90° angle so 90-30 = 60 so x is 60°
hope this helps :)
full timers work 5 hours a day whereas Part timers work 3 hours a day!
<u>Step-by-step explanation:</u>
Here we have , The difference in hours between full times and the part timers to work three hours a day is 2 working hours . We need to find that how many hours per day to full timers work . Let's find out:
Let full timers work x hours , Part time workers work 3 hours a day , According to question, difference in hours between full times and the part timers to work three hours a day is 2 working hours i.e.
⇒ 
Adding 3 to make x term alone :
⇒ 
⇒ 
Therefore, full timers work 5 hours a day whereas Part timers work 3 hours a day!
