x = 7 and x = –7.
Solution:
Given data:
and 
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
To isolate the constant term subtract 15 from both sides.
49 can be written as 7².
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
Answer:
0
Step-by-step explanation:
You can't make 0.2 as a whole number so we can round it to the nearest whole number, 0.
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
