A mini-golf course is determining the par score for each of its holes. The dot plot shows the number of strokes required to plac

e a ball in the ninth hole for a sample of 31 players. Which measure of center is best to use to determine the expected number of strokes required for the ninth hole

The mean is the unit of center that may be used to predict how many strokes will be needed to complete the ninth hole.

The data is almost symmetrical, making the mean the best option.

What is symmetrical data?

  • Asymmetric communications refers to any system where, when averaged over time, the data speed or amount is different in one direction from the other.
  • Asymmetry is defined as the lack of precise similarity between two pieces.
  • A fiddler crab's body is asymmetrical, as evidenced by the fact that one of its claws is larger than the other.
  • Absence of a standard unit of measurement between two things or amounts; incomprehensibility.

So the more about symmetrical visit.

<h3>Answer:   5 < x < 29</h3>

=========================================

Explanation:

Since AB is smaller than AD, this must mean the angle ACB is smaller than angle ACD. Note how these angles are opposite the sides mentioned.

So 2x-10 < 48

At the same time, 2x-10 is also larger than 0.

Overall, we can say 0 < 2x-10 < 48

---------

Let's solve for x

0 < 2x-10 < 48

0+10 < 2x < 48+10 ...... add 10 to all sides

10 < 2x < 58

10/2 < x < 58/2 ..... divide all sides by 2

5 < x < 29

At a store, a hat has a regular price of a dollars. During a sale, the price of that hat is discounted by 20%.The expression 0.8
OlgaM077 [116]

Answer:

Question?

Is the wording: price of "a" dollars, (in italics)?

If so, the equation would be:

0.8a

Otherwise, if "x" represents the regular price, then the equation would be:

0.8x

A rectangular field is 95 meters long and 65 meters wide. Give the length and width of another rectangular field that has the sa
Lena [83]

Answer:

There are a ton of answers. For instance, 1m by 159m.

Step-by-step explanation:

The formula for the area is a=l*w, where l and w are constants.

The formula for perimeter is p=2l+2w

The question wants another rectangle that has the same perimeter, but a smaller area.

The perimeter of the two fields has to be:

p=(2*95)+(2*65)\\p=190+130\\p=320

Thankfully, the question never specified how much smaller the area has to be. So let's go to the logical extreme and make it 1 meter wide. To conserve the perimeter, we'd have to add the removed 64 meters to the original 95 meters of length, resulting in a rectangle with a width of 1m and a length of 159m. This results in an area of exactly 159 m^{2}. The original rectangle had an area of 6175m^{2}. Mission accomplished!

But why stop there? Let's go even further down this rabbit hole!

Instead of 1, why don't we take it several steps further and use 0.0000001? At that point, the length would end up being  159.9999999m.

The area would be 0.00001599999999 m^{2}.

Let's go further!!

Width: 0.00000000000000000001

Length: 159.99999999999999999999

Area: 0.00000000000000000001599999999999999999999 (approximate).

One more, for old time's sake.

Width: 0.00000000000000000000000000000000000000000000000001m

Length: 159.99999999999999999999999999999999999999999999999999m

Area: 0.00000000000000000000000000000000000000000000000015999999999999999999999999999999999999999999999999999 m^{2}

At that point, there's so little area in the plot of land that you could claim it has no area!

Which constant number would be an to both sides of the equation rn order to complete the square for the quadratic function 1=x^2
AnnZ [28]

Answer:

k = 9

Step-by-step explanation:

Given

1= x^2 - 6x

Required

The perfect number

The coefficient c of x in the above equation is:

c = -6

Divide by 2

c/2 = -3

Square both sides

(c/2)^2 = 9

Hence, the constant to add is:

k = 9
