An apartment complex has a floor plan with dimensions shown. To effectively air condition a room, 20 BTU’s are required for ever

kifflom [539]

12,900 BTU's are required to cool the room effectively.

Step-by-step explanation:

Step 1:

We must calculate the area of the entire shape to determine the minimum BTU's required to cool the room effectively.

It is made up of a semi-circle a rectangle, and a trapezoid.

Step 2:

The area of a semi-circle $=\frac{ \pi r^{2} }{2} .$

Here, the diameter is 20 feet so the radius is 10 feet.

The area of the semi-circle $=\frac{ \pi r^{2} }{2} =\frac{ (\pi) (10^{2}) }{2} = 157.079$ square feet.

The area of a rectangle $= (l)(w).$

The length of the rectangle is 22 feet and the width is 20 feet.

The area of a rectangle $= (l)(w) =(22)(20) = 440$ square feet.

The area of a trapezoid $=\frac{a+b}{2} (h).$

Here $a=12, b= 20, h= 3$ .

The area of a trapezoid $=\frac{12+20}{2} (3) = 48$ square feet.

Step 3:

The total area of the floor plan $=157.079+440+48 = 645.079$ square feet.

If 20 BTU's are required for a single square foot,

The number of BTU's for 645.079 square feet $= (645.079)(20)=12,901.58$ BTU's.

Rounding this off, we get 12,900 BTU's required to cool the room effectively.

2x+y=5 and x+2y=4<br><br> Graph system of equation

Lera25 [3.4K]

To solve for this you need to solve for y. Equation should look like this y=mx+b Once your done solving for y, look for the y intercept which is the b, then plot that number on the y axis on the coordinate plane then look at the slope the mx if it is not a fraction already put a 1 under it. Then do rise over run to find your next point on the coordinate plane. And that's about it of graphing system of equation

Suppose you have the following null and alternative hypothesis

Sholpan [36]

A type I error takes place if a given null hypothesis is rejected but is said to be true in the population such as the forecast shows it is snowing outside but actually it is isn't.

<h3>What is type 11 error?</h3>

A type II error is known to be a statistical term that tells the error that takes place when one fails not to accept a null hypothesis that is said to be really false. A type II error create a false negative.

It known is known also as an error of omission. Example is the forecast shows that It is not snowing but it is actually snowing.

Note that:

Type I error is false positive.
Type II error is false negative.

The power of the test shows that:

The Power is the likelihood of rejecting the null hypothesis even if it is false.
Power is the likelihood of making the right decision that is to reject the null hypothesis even if the null hypothesis is false.
Power is the likelihood of not making a Type II error and others.

See full question below

Suppose you have the following null and alternative hypothesis:

H o: it is snowing.

H a: It is not snowing

(B) Describe Type II error

(C)Describe power of the test
