Answer:
0.216
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
The probability that an event will happen added to the probability that the event will not happen gives 1. In other words, the outcome of a probability cannot exceed 1.
The probability that an event a will happen or that another independent event b will happen is the sum of the probability that a will happen to the probability that b will happen.
The probability that the event B will occur 3 times in a row may be interpreted as BBB and in probability, "and" is interpreted as multiplication while "or" is addition.
Pr(BBB)
= 0.6 * 0.6 * 0.6
= 0.216

Answer:
C (0, 9)
Step-by-step explanation:
First, X is reflected across the line x=2.
X(4, -7) becomes X'(0, -7).
Next, X' is reflected across the line y=1.
X'(0, -7) becomes X"(0, 9).

Step-by-step explanation:
During the Boston Marathon, a What are the unit rates for this situation? (How far can they run in 1 hour and how long does it take to run 1 mile?)
If a certain runner averages running 25 miles in 5 hours, then
25miles = 5hrs
To determine how far they can run in 1 hour, then;
X = 1hr
Divide both expressions
25/x = 5/1
5x = 25
X = 5miles
Hence the runner can run 5miles in an hour
Similarly if
25miles =1hr
1mile = y
25y = 1
Y = 1/25
Y = 0.04hrs
Hence the time taken to run 1mile is 0.04hrs
