Just find the slope
that is ((f(6)-f(2))/(6-2)

f(6)=6^2+5(6)-8=36+30-8=58
f(2)=2^2+5(2)-8=4+10-8=6


average is (f(6)-f(2))/(6-2)=(58-6)/(4)=52/4=13

average rate of change is 13

Answer: 13

Step-by-step explanation:

The average rate of change of a function f(x) from x_1 and x_2 is given by :-

A=\frac{f(x_2)-f(x_1)}{x_2-x_1}

Therefore, for the given function f(x)=x^2+5x-8, the average rate of change from x = 2 to x = 6 is given by :-

A=\frac{f(6)-f(2)}{6-2}\\\\=\frac{(6^2+5(6)-8)-(2^2+5(2)-8)}{4}\\\\=\frac{58-6}{4}\\\\=\frac{52}{4}=13\\\\\Rightarrow A=13

Hence, the average rate of change from x = 2 to x = 6 is 13.

Two pumps connected in parallel fail independently of one another on any given day. The probability that only the older pump wil
Bogdan [553]

Answer : Probability that the pumping system will fail on any given day = 0.005

Explanation:

Probability that only older pump fail = P(A) = 0.10

Probability that only newer pump fail = P(B) = 0.05

Since they are independent events ,

then the conditions will be

P(A∩B) = P(A). P(B)

             = 0.10 ×0.05

             =  0.005

Hence, the probability will fail on any given day = 0.005

Convert 80 km per hour and 120 km per hour to meters per second​
Burka [1]

hi brainly user! ૮₍ ˃ ⤙ ˂ ₎ა

⊱┈────────────────────────┈⊰

\large \bold {ANSWER}

  • \large \boxed { \large \sf \green{ 80 km/h = 22.22 m/s }}
  • \large \boxed { \large \sf \green{ 120 km/h = 33.33 m/s }}

\large \bold {SOLUTION}

The first thing we must do is convert kilometers to meters. We will do this by multiplying by 1,000, since 1 km corresponds to 1,000 meters.

  • 80*1000 = 80,000
  • 120*1000 = 120,000

Now that we've done that, let's divide the values by 3,600, because an hour is 60 minutes, and each minute is 60 seconds, so 60*60 is 3,600.

\frac{80.0\not0\not0}{3.6\not0\not0}=22.22

\frac{120.0\not0\not0}{3.6\not0\not0}=33.33

Hence, 80 km/h = 22.22 m/s, 120 km/h = 33.33 m/s

Which correlation coefficient represents a moderate negative correlation? r = –0.04 r = –0.24 r = –0.64 r = –0.94
fomenos

The correlation coefficient is a number that indicates the direction

and closeness of points of a line of best of fit.

So it tells us two things.

It tells us the direction of the line of best fit

and it tells us the closeness of the points.

Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.

It will be a negative correlation because the slope is negative.
