<span>( 5, 2) and ( 6, 4)
slope m = (4-2)/(6-5) = 2

y = mx + b
b = y - mx
b = 2 - 2(5)
b = 2 - 10
b = -8

so now you have slope m = 2 and y intercept b = -8

equation
y = 2x - 8

answer

The color with the highest frequency would have the longest bar, followed by the 2nd highest, then the third, and so on. Thus, frequency should tally with the length of the bar.

From the table given, the top 3 are:

Pink polka dots => 12

Purple => 8

Ted and orange stripes => 7

Green => 6

Blue and gray => 4

Yellow => 3

The graph that has length of bars that corresponds to the frequency of the colors is graph C

What is the volume of the following triangular pyramid?
Readme [11.4K]

Answer:

The volume of the triangular  pyramid

         V = 566.66 in³

Step-by-step explanation:

<u><em>Step(i):-</em></u>

The volume of the triangular  pyramid

            = \frac{1}{3} X base area X height

Base area  = Area of the triangle

             A= \frac{1}{2} X base  X height

 Given the base of the triangle  (b) = 17in

  Given Height of the triangle (h ) =10 in

    A= \frac{1}{2}( 17 ) (10) = 85

The base area of the pyramid ( A) = 85 in²

<u><em>Step(ii):-</em></u>

<u><em>Given the height of the pyramid  (h) = 20in</em></u>

The volume of the triangular  pyramid

            = \frac{1}{3} X base area X height

The volume of the triangular  pyramid

         = = \frac{1}{3}( 85)(20) = 566.66

<u><em>Final answer:-</em></u>

The volume of the triangular  pyramid

         V = 566.66 in³
