Using the mean concept, it is found that the average monthly rainfall that will have to occur for the rest of the season in order to equal last year is of 1.25 inches per month.

The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In the four months from March 1 to June 30, 31 - 26 = 5 inches are needed to match last year's amount, hence the average is given by:

A = 5/4 = 1.25 inches per month.

The coordinates A(0, 0), B(0, 5) and C(3, 0) are graphed and connected together. What 3-dimensional shape will be created when t

Free_Kalibri [48]

Answer:

The 3-dimensional shape created will be a cone

Step-by-step explanation:

step 1

Plot the points

we have

A(0, 0), B(0, 5) and C(3, 0)

The figure is a right triangle

see the attached figure

When this shape is rotated about the y-axis, the 3-dimensional shape created will be a cone

where

AC is the radius of the base of cone

The radius is equal to r=AC=3 units

AB is the height of the cone

The height is h=AB=5 units

BC is the slant height of the cone

Applying Pythagoras Theorem

$BC^{2} =AB^{2} +AC^{2}$

$BC^{2} =5^{2} +3^{2}$

$BC^{2} =34$

$BC=\sqrt{34}\ units$
