Answer:

$2.01 \: {inches}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$area \: of \: circle \: = \pi {r}^{2}$

Let pi be (3.14), the radios as given in the question is (1.6 ÷ 2 = 0.8). Therefore;

$\pi {r}^{2} = \\ (3.14) \: {(0.8)}^{2} \\ 3.14 \times 0.64 = \\ 2.0096\: or \: 2.01{inches}^{2}$

Answer:

The cost of apple juice per ounce is 20 cents.

Explanation:

We know that a

ounce bottle is

3.20

and we want to find how much per ounce is.

So we set up a proportion and let

be the cost of one ounce:

3.20

Now we can cross multiply:

3.20

Divide both sides by

3.20

Therefore,

0.20

The cost of apple juice per ounce is 20 cents.

Hope this helps!

Answer:

The resulting residual value is e=-40.24.

Step-by-step explanation:

The residual value e for a regression model is defined as the difference between the real value y and the predicted value yp:

$e=y-y_p$

The predicted value for DISTANCE=0.43 miles is:

$RENT = 1200.4326 - 256.2567\cdot DISTANCE\\\\RENT(0.43) = 1200.4326 - 256.2567\cdot 0.43\\\\RENT(0.43) = 1200.4326 - 110.1904=1090.2422\\\\$

Then, if the real value is $1,050, the residual value is calculated as:

$e=y-y_p\\\\e=1050-1090.2422=-40.2422$

The value of x in the triangle is (a) 22

<h3>How to solve for x?</h3>

The complete question is in the attached image.

From the attached image of the triangle, we have:

$\sin(45) = \frac{x}{22\sqrt 2}$

Evaluate sin(45)

$\frac{1}{\sqrt 2} = \frac{x}{22\sqrt 2}$

Solve for x

$x = \frac{22\sqrt 2}{\sqrt 2}$

Divide

x = 22

Hence, the value of x is (a) 22
