Answer:

(C)

Step-by-step explanation:

From the given figure, we can see that 8 is an outlier which is at a very large distance from the rest of the data values that ranges between 300 to 500.

Thus, In this distribution, 8 is an outlier.

Now, In order to find the measure of variability in the distribution, if the distribution contains an outlier, then Inter Quartile range is the best measure of variability of the distribution.

Thus, The IQR is the best measure of variability because the distribution has an outlier.

Hence, option C is correct.

Answer:

<C=26

<B=48

<D=106

<F=42

Step-by-step explanation:

I labeled all the angles to help this make more sense :)

So first we find <C, which is supplementary to <E so just do 180-154=26

Next, we know that <F and <B are equal because they form corresponding angles.

Angles <C <D and <B form a triangle. The three angles of a triangle always equal 180. Now that we know angles <C and <B, we just do 180-26-48=106.

Lastly, to find angle A, we just take 180-106-48=42.

Hope this helps

Reflect (-1, 4) over the x-axis.

Eva8 [605]

Answer:

(- 1, - 1 )

Step-by-step explanation:

under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

(- 1, 4 ) → (- 1, - 4 )

a translation of 3 units up means adding 3 to the y- coordinate , so

(- 1, - 4 ) → (- 1, - 4 + 3 ) → (- 1, - 1 )

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large

sergey [27]

Answer:

R = 10 cm

Step-by-step explanation:

The area of a spherical shape is given by :

$A=4\pi r^2$

Where

r is the radius of the sphere

ATQ,

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.

The radius of each small bubble is 5 cm

Using the given condition,

$4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm$

So, the radius of the large bubble is equal to 10 cm.
