Answer:

y = 9.8x + 6.7

y = 6.7x + 9.8

y = 7.5x + 3.8

y = 3.8x + 7.5

Step-by-step explanation:

I made 2represent x.

y= 9.8(2) + 6.7

y = 26.3

y=6.7(2) + 9.8

y= 23.2

y= 7.5(2) + 3.8

y= 18.8

y= 3.8(2) + 7.5

y= 15.1

Answer:

y = 9.8x + 6.7

y = 7.5x + 3.8

y = 6.7x + 9.8

y = 3.8x + 7.5

Step-by-step explanation:

Let x be 10.

y = 7.5(10) + 3.8

y = 75 + 3.8

y = 78.8

y = 9.8(10) + 6.7

y = 98 + 6.7

y = 104.7

y = 3.8(10) + 7.5

y = 38 + 7.5

y = 45.5

y = 6.7(10) + 9.8

y = 67 + 9.8

y = 76.8

The output values all differ, arrange the sets in order from greatest rate of change to least rate of change.

Given f(x) = 4x3 − 12x2 + 40x + 12, find f(–2). A) f(–2) = –52 B) f(–2) = –96 C) f(–2) = –108 D) f(–2) = –148

AURORKA [14]

Given function : $f(x) = 4x^3 -12x^2 + 40x + 12$ .

We need to find the values of f(-2).

In order to find the value of f(-2), we need to plug x=-2 in the given fucntion $f(x) = 4x^3 -12x^2 + 40x + 12$ .

Replacing x by -2, we get

$f(-2) = 4(-2)^3 -12(-2)^2 + 40(-2) + 12$

We get (-2)^2 = -2 *-2*-2=-8 and (-2)^2 = -2 * -2 = 4.

$f(-2) = 4(-8) -12(4) +40(-2) +12$ .

$f(-2) = -32 -48 -80+12.$

f(-2) = -160 +12.

f(-2) = -148.

Therefore, correct option would be option D. That is f(-2)=-148.

A certain car model has a mean gas mileage of 34 miles per gallon (mpg) with a standard deviation A pizza delivery company buys

zubka84 [21]

Answer:

$z =\frac{33.3- 34}{\frac{5}{\sqrt{54}}}= -1.028$

$z =\frac{34.3- 34}{\frac{5}{\sqrt{54}}}= 0.441$

An we can use the normal standard table and the following difference and we got this result:

$P(-1.028$

Step-by-step explanation:

Assuming this statement to complete the problem "with a standard deviation 5 mpg"

We have the following info given:

$\mu = 34$ represent the mean

$\sigma= 5$ represent the deviation

We have a sample size of n = 54 and we want to find this probability:

$P(33.3 < \bar X< 34.3)$

And for this case since the sample size is large enough >30 we can apply the central limit theorem and then we can use this distribution:

$\bar X \sim N(\mu , \frac{\sigma}{\sqrt{n}})$

And we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z =\frac{33.3- 34}{\frac{5}{\sqrt{54}}}= -1.028$

$z =\frac{34.3- 34}{\frac{5}{\sqrt{54}}}= 0.441$

An we can use the normal standard table and the following difference and we got this result:

$P(-1.028$

ASAP. Can someone help me find the percentage of these please, I can't figure it out. (Pic below)

atroni [7]

Answer:

Interphase: 55.56%

Prophase: 27.78%

Metaphase: 8.33%

Anaphase: 5.56%

Telophase: 2.78%

Step-by-step explanation:

All you need to do is follow the instructions. To get the percentage, all you need to do is divide the part by the whole then multiply it by 100%.

$\dfrac{Part}{Whole}\times 100\%$

Now let's take your problem:

Number of cells in interphase:

20 this is the part and the whole would be the total cells, which is 36. Now we insert that into our equation:

$\dfrac{20}{36}\times 100\%=0.5556\times100\%=55.56\%$

So now we apply the same to the rest:

Prophase:

$\dfrac{10}{36}\times 100\%=0.2778\times100\%=27.78\%$

Metaphase:

$\dfrac{3}{36}\times 100\%=0.0833\times100\%=8.33\%$

Anaphase:

$\dfrac{2}{36}\times 100\%=0.0556\times100\%=5.56\%$

Telophase:

$\dfrac{1}{36}\times 100\%=0.0278\times100\%=2.78\%$
