The chalk circle around the pitcher's mound has a diameter of 16 ft. What is the area of the pitcher's circle?

Answers

Answer:

The area is approximately 201.06

Step-by-step explanation:

If you use the equation pi r^2, then we will get the answer. Since the diameter is double the radius, we should know that the radius is 8ft. Then we do the math and get the answer above.

Answer: A≈201.06ft²

Step-by-step explanation:

How to Calculate Diameter?

Diameter = Circumference ÷ π (when the circumference is given)

Diameter = 2 × Radius (when the radius is given)

Diameter = 2√[Area/π] (when the area is given)

The sum of the residuals should always be 0 because the predicted values should be that close to the actual values.
True or false

Answers

Answer: True

Step-by-step explanation:

The sum of the residuals is always 0 so the plot will always be centered around the x-axis. An outlier is a value that is well separated from the rest of the data set. An outlier will have a large absolute residual value.

The answer is TRUE

Combine like terms: 4-4z+5z-2+2z then solve

Answers

Answer:

3z+2

Step-by-step explanation:

Answer:

2 + 3z

Step-by-step explanation:

4 - 4z + 5z - 2 + 2z

4 - 2 = 2

-4z + 5z + 2z = 3z

= 2 + 3z

We don't know what 'z' is, so that is the most that I can simplify it.

4 - 4z + 5z - 2 + 2z

= (4) + (-4z) + (5z) + (-2) + (2z)

What is the value of X?

Answers

Answer:

x = 60

Step-by-step explanation:

<DGC = 90 degrees            Given

<AGB = <DGC                       Vertically opposite angles.

<AGB = 90 degrees.            <AGB takes on the properties of <DGB

30 + x + 90 = 180                 The three angles make up a line.

120 + x = 180                         Combine like terms..

x = 180 - 120                          Subtract 120 from both sides

x = 60

X=60 because angle G is 90° making the two angles D and E having to add up to 90 as well. D would =60 then because 90-30=60. Then angle X is vertical to that making the two angles congruent.

Noah bought stock in a company two years ago that was worth x dollars. During the first year that he owned the stock, it increased by 31%. During the second year the value of the stock increased by 15%. Write an expression in terms of x that represents the value of the stock after the two years have passed.

Answers

Answer:

1.5065x

Step-by-step explanation:

x + (0.31x) + 0.15(1.31x)

x is the initial amount, 0.31x is the 31% of the original amount, and we're adding that. The 15% earned the next year is on the new total of what he had after that first bump...x + 0.31x = 1.31x

Simplify:

x + (0.31x) + 0.15(1.31x)

= 1.31x + 0.1965x

=1.5065x
