Answer:
4.3275
next time use a standard deviation calculator they are really easy to use just look it up on google
Answer:
Step-by-step explanation:
a) this graph is that of a parabola that opens up. As is the case for all parabolas, the domain is the set of all real numbers. The range begins with the smallest y-value, which is -4, extending upwards from there: [-4, infinity)
b) this graph's shape most closely resembles that of a polynomial; as we move from left to right, y increases, reaches a local maximum, decreases to a local minimum, and then continues to increase with x. As is the case for all polynomials, the domain is the set of all real numbers. As we move from x = 0 to the left, y decreases without bound; from x ≥ 12 onward, y increases without bound; thus, the range is (-infinity, +infinity).
c) The graph represents a quarter of an ellipse for which x begins at -40 and ends at [4, -16]. Thus, the domain is [-40, 4]. By inspection we see that the smallest y value is -16 and the largest is 4; thus, the range is [-40, 4].
C. The graph g(x) = x − 7 is the result of translating the graph of f(x) = x + 3 down 10 units.
Sure hope this helps you and good on whatever math test or exam is coming up soon!! :D
A= 2 to the power of -1
Because if it's the same base no in multiplication we add the indices and in division we subtract the indicies
There is no solutions, I think you got the signs mixed up.
