(C) (-2, -36) . . . . . . is the appropriate choice

_____
An easy way to tell is to let a graphing calculator show you.

Or, you can rearrange the equation to vertex form.
  f(x) = 5(x² +4x) -16
    = 5(x² +4x +4) -16 -5*4 . . . . complete the square
    = 5(x +2)² -36
So, the vertex is (-2, -36).

DiKsa [7]

Answer:

mean <median <mode

Step-by-step explanation:

We must calculate the measures of central tendency, which are the mode, the mean and the median.

fashion, value that is most repeated, in this case 87

median, the mean value, how is an even number, the mean is the average of these central numbers, in this case it is 82 and 87

(82 + 87) / 2 = 84.5

average, is the average of all the data, we calculate it like this:

(60 + 74 +82 +87 +87+ 94) / 6 = 80.66

Therefore, the relationship would be like this:

mean <median <mode

tekilochka [14]

Answer:

0.9984

Step-by-step explanation:

we have shape parameter for the first component as 2.1

characteristics life = 100000

for this component

we have

exp(-2000/100000)².¹

= e^-0.0002705

= 0.9997

for the second component

shape parameter = 1.8

characteristic life = 80000

= exp(-2000/80000)¹.⁸

= e^-0.001307

= 0.9987

the reliability oif the system after 2000  events

= 0.9987 * 0.9997

= 0.9984

= 9/4 + 3 + 3

= 9/4 + 6

= 33/4
