The departure from the average is the difference between the actual amount of rain and the average amount of rain for a given mo

Neporo4naja [7]

The actual rainfall for last June is 0.5

1.14 is the amount of rain that fell last July.

2.43 is how much rain would have to fall for August to match the three months average

0.86 is the departure from the average in August

Step-by-step explanation:

1. 0.67-0.17 = 0.5

2. 1.5-0.36 = 1.14

What is cubic spline?

lara [203]

Answer:

Here is your answer

Step-by-step explanation:

A cubic spline is a spline constructed of piecewise third order polynomials which pass through a set of control points. The second derivative of each polynomial is commonly set to zero at the endpoints since this provides a boundary condition that completes the system of equations.

Solve this to pretty pretty pls

Answer:

3) 161

Step-by-step explanation:

Indeed this is pretty easy :D

What we need to find is the surface area of the rectangular prism excluding the area of the hole. First, let's find out the width of the box, we can do this by using the area, the length, and the height, and we can write:

$V=lhw$

(Formula to find the volume of a rectangular prism)

$140=(4)(7)w\\ 140=28w\\ 5=w$

Now that we have the width, can find the area of the top part of the prism:

$(5)(4)=20$

The area of the top part of the prism is 20, and the circle has 1/4 of the area of that:

$A_{circle} = \frac{A_{top part} }{4}\\ A_{circle} = \frac{20}{4} \\ A_{circle} = 5$

So the area of the circle is 5. Now we just need to find the surface area of the rectangular prism and subtract that result with the area of the circle:

$A_{circle}=5\\ SA_{rec.pri.}=2(lh+lw+wh)\\ SA_{rec.pri.}=2((4)(7)+(4)(5)+(5)(7))\\ SA_{rec.pri.}=2(28+20+35)\\ SA_{rec.pri.}=2(83)\\ SA_{rec.pri.}=166$

Subtract these two results...:

$166-5=161$

And we are done!
