PLEASE HELP Given the function f(x) = 3x2 – 4

Zarrin [17]

Answer:

15

Step-by-step explanation:

Rate of change is the slope of the tangent which will be the derivative of the function

if f(x) = 3x² - 4

f'(x) = 6x

as the derivative is linear, the average rate of change will occur at the midpoint of the interval

f'(2.5) = 6(2.5) = 15

The midpoint M of the line segment AB is (-3,7). If the coordinate of B is (5,-1), what is the coordinate of the point A?

sleet_krkn [62]

Answer:

Coordinate of Point A is (-11, 15)

Step-by-step explanation:

M -- (-3, 7)

B -- (5, -1)

Therefore, (5 + x)/2 = -3

x = -11

(-1 + y)/2 = 7

y = 15

Therefore Point A is (-11, 15)

Which ordered pair makes the inequality true? 2x + y > 8

Katena32 [7]

It could be multiple different answers. Any answer that will equal something higher than 8. Let's say (2, 5) for example. 2(2)+(5)>8 Two times two equals four plus five equals nine. Nine is greater than eight, therefore (2, 5) is true.
Hope this helps!

A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with known standar

Vsevolod [243]

Answer:

This is a reasonable decision because the sample size has no effect on the 90% confidence interval

Step-by-step explanation:

90% confidence interval

larger sample size = 20

condition : sample mean ( x-bar ) is the same for both samples

<em>This is a reasonable decision because the sample size has no effect on the 90% confidence interva</em>l

<u>from condition 1 :</u>

Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%

<u>for condition 2 :</u>

sample size = 20

mean = 2.25 ( assumed value )

std = 0.15 ( assumed value )

Z = 1.645 ( Z-value )

determine the 90% confidence interval

= mean ± z $\frac{std}{\sqrt{n} }$

= 2.25 ± 1.645 $\frac{0.15}{\sqrt{20} }$

= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )
