Answer:
ΔABC ≅ ΔFED
Explanation:
Look at the alignment and position of the letters.
A = F
B = E
C = D
Properly align the letters in order to their corresponding position.
ΔA ≅ ΔF
ΔAB ≅ ΔFE
ΔABC ≅ ΔFED
Answer:
Class interval 10-19 20-29 30-39 40-49 50-59
cumulative frequency 10 24 41 48 50
cumulative relative frequency 0.2 0.48 0.82 0.96 1
Step-by-step explanation:
1.
We are given the frequency of each class interval and we have to find the respective cumulative frequency and cumulative relative frequency.
Cumulative frequency
10
10+14=24
14+17=41
41+7=48
48+2=50
sum of frequencies is 50 so the relative frequency is f/50.
Relative frequency
10/50=0.2
14/50=0.28
17/50=0.34
7/50=0.14
2/50=0.04
Cumulative relative frequency
0.2
0.2+0.28=0.48
0.48+0.34=0.82
0.82+0.14=0.96
0.96+0.04=1
The cumulative relative frequency is calculated using relative frequency.
Relative frequency is calculated by dividing the respective frequency to the sum of frequency.
The cumulative frequency is calculated by adding the frequency of respective class to the sum of frequencies of previous classes.
The cumulative relative frequency is calculated by adding the relative frequency of respective class to the sum of relative frequencies of previous classes.
The speed of the 747 jet is 545MPH and the speed of the 787 jet is 530MPH. that means the 747 jet is faster by 15MPH
I feel like it’s the last set but then again I haven’t done that kind of math in a few years. Hopefully that helps !
