Answer:
0.5
Step-by-step explanation:
Given that height of 7 year old children are normally distributed with mean =49 inches and std deviation = 2inches
Brenda is 50 inches tall
This means her X score is 50
To convert this X score to Z score we use the formula given below
Here we know all the values of x, mu and sigma
Just substitute
Z score
=
Thus Z score of Brenda is 0.5

<h2>Hello!</h2>
The answer is:
The fourth graph.
<h2>Why?</h2>We are given the following equation:
Then, we need to find the graph of f(x+2) that will be equal to:
Now, finding the x-axis interception, making "y" equal to 0, we have:
Therefore, the x-axis interception point is located at (-2,0), it matches with the fourth graph.
Now, finding the y-axis interception, making "x" equal to 0, we have:
Therefore, the y-axis interception point is located at (0,2), it matches with the fourth graph.
Hence, we have that the graph of f(x+2) is the fourth graph since the second graph function cuts the x-axis at -2 and the y-axis at 2.
Have a nice day!
