Answers

The center of the circle will be (4, -3) and the radius of the circle will be 6 units. Then the correct option is A.

What is an equation of a circle?

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x - h)² + (y - k)² = r²

The equation is given below.

x² - 8x + y² + 6y - 11 = 0

     x² - 8x + y² + 6y = 11​​

Then the center and the radius of the circle will be

x² - 8x + 16 + y² + 6y + 9 = 11​ + 16 + 9

             (x - 4)² + (x + 3)² = 36

             (x - 4)² + (x + 3)² = 6²

Thus, the center and the radius of the circle will be (4, -3) and 6 units respectively.

Red Blue Yellow

Answers

Answer:

Step-by-step explanation:

Comment

The theoretical probabilities are

Red: 8/20 = 0.4

Blue:6/20 = 0.3

yellow:6/20 = 0.3

The experimental Probabilities are

Red: 11/40 = 0.275

blue: 11/40 = 0.275

Yellow: 18/40=0.45

Both probabilities add to 1 as they should

The yellow is the highest disproportionate answer and it really shouldn't be. If anything it should be red. (0.45 > 0.4 comparing yellow experimental with red theoretical. The yellow is way more than it should be)

The number of trials is double the number of marbles in the jar. The number of trials would be double for each color in the jar. Both blanks are double.

The vertices of an isosceles triangle are a(3, 6), b(7, 2), and c(4, 3). what is the equation of the triangle's line of symmetry?
y = x + 1
y = x - 1
y = x
y = -x + 1

Answers

Based on the calculations, the equation of the triangle's line of symmetry is equal to: B. y = x - 1.

How to determine the equation of the triangle's line of symmetry?

First of all, we would determine the midpoint where the line of symmetry passes through points A and B:

Midpoint at point A = (3 + 7)/2 = 10/2 = 5.

Midpoint at point B = (6 + 2)/2 = 8/2 = 4.

Point D = (5, 4)

Mathematically, the standard equation of a line is given by y = ax + b.

D(5, 4); 4 = 5a + b   ....equation 1.

C(4, 3); 3 = 4a + b    ....equation 2.

Subtracting eqn. 2 from eqn. 1, we have:

1 = a

Next, we would find the value of b:

4 = 5a + b

4 = 5(1) + b

b = 4 - 5

b = -1.

Therefore, the equation of the triangle's line of symmetry is given by:

y = ax + b

y = x(1) + (-1)

y = x - 1.

The average amount of milk used for an orders of pancakes can be found by taking the total number of cups used for the 10 pancakes and take the answer divided by 10 (the amount of total pancakes)
We have 6 of 1/2 cups, 2 of 1/4 cups and 2 of 3/4 cups
So there are a total of [6•(1/2)]+[2•(1/4)]+[2•3/4]=5 cups for the total of 10 pancakes
Therefore, the average amount of milk used for an order of pancakes is 5/10=1/2 cups.

Answer:

3.) (5,2), (5,5), and (9,2)

Step-by-step explanation:

The triangle currently has the coordinates (2,0), (6,0), and (2,3).

If you want to translate the triangle up 2 units, you need to add 2 to each "y" value.

(2,0)  -----------> y = 0  ------------> new y = 2

(6,0) -------> y = 0   --------------> new y = 2

(2,3)  ----------> y = 3 -----------> new y = 5

If you want to translate the triangle 3 units to the right, you need to add 3 to each "x" value.

(2,0)  -----------> x = 2  ------------> new x = 5

(6,0) -------> x = 6  -------------->  new x = 9

(2,3)  ----------> x = 2 ----------> new x = 5

Therefore, the new coordinates are (5,2), (9,2), and (5,5).

A motorbike was discounted by 10% and sold for $5220. What was the cost of the motorbike before the discount was applied?​

Answers

Answer: $5,800

So the motorbike was discounted by 10% and sold for $5220, that means $5220 is 90% of x. Let x be the original value. Now, set up a proportional equation. 5220/90=x/100. Multiply 5220 by 100, that will give you 522,000. Now let’s divide that by 90, and the answer will be $5800.

The number of ways that Grant can arrange 3 of his 10 plants on a window ledge is 120 ways

How to solve the combination problem?

The number of ways that Grant can arrange 3 of his 10 plants on a window ledge will be:

= 10!/(10! - 3!)3!

= 10!/7!3!

= (10 × 9 × 8)/(3 × 2)

= 120

When the parade organizer received 8 entries for floats, the number of ways that he can arrange 4 floats out of the 8 entries will be:

= 8!/(8! - 4!)4!.

= 8!/4!4!

= (8 × 7 × 6 × 5)/(4 × 3 × 2)

= 70

4! in expanded form will be:

= 4 × 3 × 2
