Answer:
Each friend has 1/28 of the whole pizza.
Step-by-step explanation:
1/2 ÷ 7/1 = 1/14
1/14 ÷ 2 = 1/28
Answer:
a) D. The group of all of the babies whose recorded weights were examined
b) A. The weights of the babies at birth
c) i) Ux' = u = 3370;
s.d = 43.95
ii) Ux' = u = 3370
s.d = 35.109
Step-by-step explanation:
Given:
Mean, u = 3370
Standard deviation = 582
a) Population in statistics involves every member of the group in study.
Here, the correct population is the group of all of the babies whose recorded weights were examined.
b) In statistics, variable involves data collected.
The correct variable is the weights of the babies at birth
c)
i) at X' = 175
Sample mean:
Ux' = u = 3370
Standard deviation:
ii) at X' = 175
Sample mean:
Ux' = u = 3370
Stanard deviation:
Answer:
Step-by-step explanation:
<u>You just need to sum up the values according to arc addition postulate:</u>
- <em>the measure of the arc formed by two adjacent arcs is the sum of the measures of the two arcs</em>
- m(arc AD) = m(arc AC) + m(arc CD)
- m(arc AD) = 35° + 45° = 80°
No because 10*12=120 and in order for them to be proportional 8*25 would have to = 120 as well but it doesnt
I believe it's always a parallelogram??
