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: D
Explanation: The function is an absolute value function with vertex at (-9,0). The slope of the part with x value greater than -9 is positive, and the slope of the part with x value less than -9 is negative.
Answer: no scale
Step-by-step explanation:
Answer:
the value is x is 8 and y is 7
The third one, because statistical questions have variables that can change
