Answer:
B) The base graph has been reflected about the y-axis
Step-by-step explanation:
We are given the function, .
Now, as we know,
The new function after transformation is .
<em>As, the function f(x) is changing to g(x) = f(-x)</em> and from the graph below, we see that,
The base function is reflected across y-axis.
Hence, option B is correct.
Answer: 0.5
Step-by-step explanation:
Given : Adult male heights have a normal probability distribution .
Population mean :
Standard deviation:
Let x be the random variable that represent the heights of adult male.
z-score :
For x=70, we have
Now, by using the standard normal distribution table, we have
The probability that a randomly selected male is more than 70 inches tall :-
Hence, the probability that a randomly selected male is more than 70 inches tall = 0.5
