Answer:
x=10 and x=-6
Step-by-step explanation:
f(x)=(x-2)²-64 (Given)
0=(x-2)²-64 (Set equation equal to 0)
64=(x-2)² (Add 64 to both sides)
±8=x-2 (Take the square root of both sides)
Because there are two possible roots, make 2 equations to find both:
8=x-2 and -8=x-2
10=x and -6=x
Answer:
<h2>The standard deviation is 2.6076809621.</h2>
Step-by-step explanation:
The set of values are 2, 4, 7, 8, 9.
The mean of these values are .
The mean of the squares of the differences of these numbers and the mean is .
In order to get the value of the standard deviation, we need to square-root the value of 6.8.
Hence, the standard deviation of the data set is ≅2.6076809621.
This graph shows a general trend of going down, but it's not that strong. You could say it has a fairly weak negative correlation.
Answer:
$6250
Step-by-step explanation:
5000 = 80%
5000/80=62.5
62.5*100=6250
