Answer:
a. The Venn diagram is explained in the attached word file.
0.61
b. Not independent
Step-by-step explanation:
a. The hypothetical 1000 table for given situation is
Adult(A) Not Adult (not A) Total
Travel outside (T) 610 170 780
Not Travel outside (not T) 110 110 220
Total 720 280 1000
P(Adult and travel outside)=P(A and T)=610/1000=0.61
b. Multiplication rule for independent events is
P(A and B)=P(A)*P(B)
P(A and T)=0.61
P(A)*P(T)=0.72*0.78=0.56
As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.
Answer:
A. mean 71.33, median 86, mode 90 90 100 100, range 55
B. mean 79.41, median 36.5, mode 90, range 60
c. mean 73.16, median 2, mode 75 75 80 80, range 45
Step-by-step explanation:
mean is the average so add all numbers then divide by the number of number
mode is the number that is often seen
range subtract the smallest from largest or the other way around
median the middle number when lined all number from less to biggest
Answer:
Step-by-step explanation:
By inscribed angle theorem:

Let's break this down:
The difference: Something's gotta be subtracted
Twice a number: So 2 times a number, or n
and 3: So we gotta subtract 2n and 3
is 11: The final answer is 11
So altogether is:
2n - 3 = 11
