Answer:4.55,0.47
Step-by-step explanation:
Given height varies from 3.6 feet to 5.5 feet for 95% student
i.e.
95% data falls in the interval of (\mu -2\sigma ,\mu +2\sigma )
So
-----------(1)
-----------(2)
Solving (1)&(2) we get
Thus mean=4.55
And standard deviation=0.47
Answer: First option.
Step-by-step explanation:
Below are some transformations for a function :
1. If , the function is shifted "k" units up.
2 If , the function is shifted "k" units down.
3. If , the function is shifted "k" units right.
4. If , the function is shifted "k" units left.
5. If , the function is reflected over the x-axis.
6. If , the function is reflected over the y-axis.
Then, given the parent function :
And knowing that the the other function is:
You can identify that the function is obtained by:
- Shifting the function 4 units left.
- Reflecting the function 4 over the x-axis.
- Shifting the function 2 units down.
