1 answer:
Masja [62]3 years ago
5 0

Answer:

f(x) = 2x² + 4x - 16

= 2(x² + 2x) - 16

= 2(x² + 2(x)(1) + 1² - 1²) - 16

= 2(x + 1)² - 2 - 16

= 2(x + 1)² - 18

Vertex: (-1, -18) minimum

Second point can be the y-intercept:

(0, -16)

It should be a concave up

Which of the following sets of data will have the smallest Standard Deviation?
uranmaximum [27]

Answer: D

Step-by-step explanation:

Standard Deviation σ2 =

Σ(xi - μ)2/N

=(1 - 5.3)2 + ... + (9 - 5.3)2/10

=68.1/10

= 6.81

σ = √6.81

= 2.60959767014

B) σ2 =

Σ(xi - μ)2/N

=(3 - 61.7)2 + ... + (99 - 61.7)2/10

=58414.1/10

= 5841.41

σ = √5841.41

= 76.429117488036

C) (1 - 11.4)2 + ... + (1 - 11.4)2/10

=8758.4/10

= 875.84

σ = √875.84

= 29.59459410095

D) (79 - 79)2 + ... + (79 - 79)2/10

=0/10

= 0

σ = √0

= 0
