The distribution of images on the pages of a 350-page catalog is found to follow normal distribution with a mean of 32 images pe

r page and a standard deviation of 8 images per page. Which conclusion does this information best support? Approximately 238 pages fall within the first standard deviation of the mean. Approximately 238 pages fall within the second standard deviation of the mean. Approximately 238 pages fall within the third standard deviation of the mean. Approximately 346 pages fall within the second standard deviation of the mean. Approximately 332 pages fall within the third standard deviation of the mean. NextReset

<span>Approximately 238 pages fall within the second standard deviation of the mean. The 68-95-99.7 rule gives that in a normal distribution, about 68% of the data fall within the first standard deviation, and 350*0.68=238. 350*0.95=332, so about 332 pages fall within the second standard deviation, and 350*99=348.95 pages fall within the third standard deviation.</span>

Jake built a skateboard ramp, if the distance of the ramp is 10 ft. The ramp rises a
ikadub [295]

Answer:

Angle made by ramp with ground is ≈19.29^{\circ}

Step-by-step explanation:

Diagram of given scenario is shown below.

Given that,

Horizontal Distance of Skateboard ramp is 10 ft.

Height of Skateboard ramp is 3.5 ft.

From figure,

It is forming a Right angle triangle \triangle ABC.

In \triangle ABC, AB=3.5 and BC=10.

Clearly see that we need to find measure of angle \angle C.

Using Trigonometric ratio:

     Tan(\theta)= \frac{Perpendicular}{Base}

So,  Tan(\angle C) = \frac{AB}{BC} =\frac{3.5}{10} =0.35

Then \angle C=Tan^{-1} (3.5)=19.290046^{\circ}

Therefore, Angle made by ramp with ground is ≈19.29^{\circ}

A cell tower is located at and transmits a circular signal that covers three major cities. The three cities are located on the c
Lelu [443]

Answer:

(x+8)^2 +(y-4)^2 = 25

Step-by-step explanation:

Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"

For this case the generla equation for the circle is given by:

(x-h)^2 +(y-k)^2 = r^2

From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this:(x+8)^2 +(y-4)^2 = r^2

If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for r^2

(-4+8)^2 +(7-4)^2 =25= r^2

So then r = \sqrt{25}=5

And if we replace the second point we got this:

(-13+8)^2 +(4-4)^2 = 25 =r^2

And for the third point we have:

(-8+8)^2 +(-1-4)^2 = 25 =r^2

And we got the same result.

So then our final equation is given:

(x+8)^2 +(y-4)^2 = 25

(-4,-2)
You just plug in the numbers from the ordered pair, into your equation. Remember, the formula for ordered pairs are (x,y). :)

1) How many 3/4 does it take to make 9/2?


     Now look at this, 3/4 x 6 = 4 1/2.  4 1/2 is the same as 9/2


   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2)  How many 3/4's go into 9/2?


    This is the same question as the 1st one so the answer is 6 :)


3)  9/2 divided by 3/4 = ??


         Use the KEEP< CHANGE< FLIP method, so it turns into  I
                                                                                                    I
                                                                                                    I
                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I


  This is equal to 36/6 which is 6 :)


The answer is 6 for numbers 1, 2, and 3 :)
