Answer:
25 km
Step-by-step explanation:
100/20=5
5*5=25
Answer: 78
Step-by-step explanation:
Step 1:
Substitute the variables in:
6(9) - 8(-3)
Step 2:
Multiply to get rid of the parentheses:
54 - -24 = 54 + 24 (the two negatives cancel out)
Step 3:
Add, and then you're done:
54 + 24 = 78

Answer:
Options D & E are independent
Step-by-step explanation:
For any of the options to be independent, they have to be mutually exclusive i.e A ∩ B = 0
A) A ∩ B = {1, 2, 3}. They are not mutually exclusive and so they are not independent.
B) A ∩ B = {3}. They are not mutually exclusive and so they are not independent.
C) A ∩ B = {8}. They are not mutually exclusive and so they are not independent.
D) A ∩ B = 0. They are mutually exclusive and thus they are independent.
E) A ∩ B = 0. They are mutually exclusive and thus they are independent.
The probability that all three people surveyed is an independent probability and the calculated probability is 0.1225
The probability a surveyed driver is worried = 35%
- Number of people surveyed = 3
Since the probability of being worried is independent ;
- Probability = P(A) × P(B) × P(C)
The probability that all 3 surveyed are worried :
- P(worried) × P(worried) × P(worried)
- (0.35 × 0.35 × 0.35) = 0.1225
Therefore, the probability that all three people surveyed are worried is : 0.1225
