Answer:

  CX = 15√2 inches

  BC = 15√3 inches

  AC = 15√6 inches

Step-by-step explanation:

In this geometry, all of the triangles are similar:

  ΔABC ~ ΔACX ~ ΔCBX

Corresponding segments are proportional in similar triangles, so we have ...

  AX/CX = CX/BX = (long leg)/(short leg)

Filling in the numbers, we get

  30/CX = CX/15

  CX² = 15×30

  CX = 15√2 . . . . . exact length of the altitude (inches)

__

Similarly, we can form proportions with the legs:

  AB/BC = CB/BX

  BC² = (BX)(AB) = (45)(15)

  BC = 15√3 . . . inches

and

  AC/AB = AX/AC

  AC² = (AX)(AB) = (30)(45)

  AC = 15√6 . . . inches

_____

Additional comment

You may notice that each of the segments we're interested in is the root of a product involving segments of the hypotenuse. This "root of a product" is called the geometric mean. Here, the three geometric mean relations are ...

  altitude = geometric mean of hypotenuse segments

  short side = geometric mean of short segment and whole hypotenuse

  long side = geometric mean of long segment and whole hypotenuse

__

Strictly speaking the geometric mean is the n-th root of the product of n items. Here, there are only 2 items, so it is the square root of their product.

She has to buy 48 inches of ribbon

Step-by-step explanation:

We know that the pillow is a square with an area of 144. This means that all the side lengths must be the same. If we take the square root of 144 we get 12 which is the length of one side of the square. Because there are four sides to a square, we multiply this by 4. So 12 x 4 = 48 inches of ribbon.

An outlier is a data value that differs greatly from other
values in a data set.
Complete the statements about the outlier rule.
If any values in the data set are
the upper boundary, then
those values are upper outliers.
If any values in the data set are
the lower boundary, then
those values are lower outliers.

Answers

Answers:

Box 1:  Greater thanBox 2: Less than

So,

If any values in the data set are greater than the upper boundary, then those values are upper outliers.If any values in the data set are less than the lower boundary, then those values are lower outliers.

The general rule is that the upper boundary is found computing Q3+1.5*IQR, where IQR is the interquartile range. Recall that IQR = Q3-Q1. The Q1 and Q3 are the first and third quartiles respectively.

Another rule is that the lower boundary is found by computing Q1 - 1.5*IQR

On a box and whisker plot, outliers are points that are not connected to the main plot itself. You can think of them as islands far from the mainland.

If any values in the data set are greater than the upper boundary, then those values are the upper outliers. If any values in the data set are less than the lower boundary, then those values are lower outliers.

What are Outliers?

If a number in distribution is more than 1.5 times the length of the box away from either of the upper and lower quartile of the distribution, then that number is said to be an outlier.  

The lower quartile is [tex]Q_1[/tex] and the upper quartile of distribution is [tex]Q_3[/tex]

Then lower boundary is given by [tex]=Q_1-1.5\times IQR[/tex]

The Upper boundary is given by  [tex]=Q_3+1.5\times IQR[/tex]

If any number or value of the distribution is greater than [tex]Q_3+1.5\times IQR[/tex] then that is called Upper Outlier.

Similarly, if any value or number of the distribution is less than [tex]Q_1-1.5\times IQR[/tex] then that is called Lower Outlier.

So the answers in the boxes are given by:

Julie weighs five watermelons and rounds the weighs to the nearest hundredth which of the weights round to 7.43 pounds

Answers

Options :

7.423 pounds

7.437 pounds

7.413 pounds

7.425 pounds

Answer:

7.425

Step-by-step explanation:

Rounding each option to the nearest hundredth:

The second digit after the decimal point is the hundredth digit, if the next digit (thousandth digit) is more than or equal to 5, then it is rounded to 1 and added to the hundredth digit value, if otherwise, it is rounded to zero.

7.423 = 7.42 (nearest hundredth)

7.437 = 7.44 (nearest hundredth)

7.413 = 7.41 (nearest hundredth)

7.425 = 7.43 (nearest hundredth)

Step-by-step explanation:

The inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.

The given function is f(x)=9x-3.

How to find the inverse of a function?

Steps for finding the inverse of a function f(x).

Replace f(x) with y in the equation describing the function.Interchange x and y. In other words, replace every x with a y and vice versa.Solve for y.Replace y with [tex]f^{-1} (x)[/tex].

Now, y=9x-3

Interchange x and y. That is x=9y-3.

Solve for y.

That is, 9y=x+3

⇒y=(x+3)/9

⇒[tex]f^{-1} (x)[/tex]=(x+3)/9

Therefore, the inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.

the classmark of the class is 162.5

Step-by-step explanation:

The computation of the class mark is shown below:

Given that

160 - 165

So, the class mark of the class is

= (160 + 165) ÷ 2

= 162.5

Hence, the classmark of the class is 162.5

two complentary angles are drawn such that one angle is 10 more than seven times the other angle find the measure of each angle

Answers

Answer:

10° and 80°

Step-by-step explanation:

Complementary angles sum to 90°

let one angle be x then the other angle is 7x + 10 , so

x + 7x + 10 = 90

8x + 10 = 90 ( subtract 10 from both sides )

8x = 80 ( divide both sides by 8 )

x = 10

and 7x + 10 = 7(10) + 10 = 70 + 10 = 80

Thus the 2 angles are 10° and 80°
