Answer:
Option (A) 0.40951
Step-by-step explanation:
We are given the following information in the question:
P(target) = 0.90
Let the random variable X represent the number of times he hits ring of the target with a shot of the arrow.
The probability distribution of X is
x: 0 1 2 3 4 5
P(x): 0.00001 0.00045 0.00810 0.07290 0.32805 0.59049
The mean of discrete probability distribution is given by:
Now, we have to evaluate
Option (A) 0.40951 t is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X.
Answer:
B, C
Step-by-step explanation:
Consider all options:
A. The graph of the function is vertically shrunk by a factor
the graph of the function
so the domain and the range of both functions are the same. This option is false.
B. The graph of the function is vertically shrunk by a factor
the graph of the function
so the domain and the range of both functions are the same. This option is true.
C. The graph of the function is translated 2 units to the right and vertically shrunk by a factor
the graph of the function
so their graphs are similar except the first graph is shifted right and shrunk vertically by a factor of
. This option is true.
D. The function has the domain and the range all non-negative real values. The function
has the domain and the range all real values. So this option is false.
