Answer:

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

Step-by-step explanation:

x² + y² -2x - 10y + 17 = 0

Find the center and radius of this circle

We have the equation

x² + y² -2x - 10y + 17 = 0

We collect like terms

x² - 2x + y² - 10y = -17

x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

A bag contains:
• 5 red marbles
• 6 blue marbles
. 3 green marbles
• 4 black marbles
• 2 yellow marbles
A marble will be drawn from the bag and replaced 100 times.
What is a reasonable prediction for the number of times a green
or black marble will be drawn?

Answers

Answer:

A green marble will be drawn 64444444444444444444444444444444444445372587542723784532784572384327542757235432785423752375428369823 to the sqaure root of 48727 times

Step-by-step explanation:

hola espanol taco chicop espanol

I think a fair argument for the green marbles is that it will be chosen 15/100 times, because if you add all marbles up you get 20 marbles in total, with 3 being green. If you multiply this by five you will get 15/100, therefore this is a reasonable prediction.

Brian rolls a fair dice 12 times. How many times would Brian expect to roll a number greater than 4?

Answers

Brian is expected to roll a number greater than 4, 4 times

How to determine the expected row?

In a fair die, we have:

Faces = 6

Faces greater than 4 = 2 i.e. 5 and 6

So, the probability to roll a number greater than 4 is:

p = 2/6

When the dice is rolled 12 times, the expected value is:

Expected = 2/6 * 12

Evaluate

Expected = 4

Hence, Brian is expected to roll a number greater than 4, 4 times

Answers

Answer:

Step-by-step explanation:

Area of the unshaded region = 95/360 * 3.14 * (5*√2)^2

Area of the unshaded region = 95/360 * 3.14 * 50

Area of the unshaded region = 41.43

Area of the entire circle = pi r^2

Area of the entire circle = 3.14 * (5√2)^2

Area of the entire circle = 157

Area of the shaded part = The whole circle's area - the unshaded part

Area of the shaded part = 157 - 41.42

Area of the shaded part = 115.57

Which of the following angle measurements would you find in an equilateral triangle?
A. 45°, 45°, 45°
B. 45°, 45°, 90°
C. 50°, 50°, 50°
D. 60°, 60°, 60°

Answers

Answer:

D. 60, 60, 60

Step-by-step explanation:

In an equilateral triangle, all sides are equal and equal to 180 when added together. because 60×3 is equal to 180, D is the right answer. I hope this helps you!

The angle measurements found in an equilateral triangle are 60°, 60°, 60°

What is an Equilateral Triangle?

An equilateral triangle is an angle that has equal angles and equal sides. It implies that all the sides of the angle contain the same length.

We can also say that an equilateral triangle is also equiangular since it has equal angles. If we recall, we know that the sum of angles in a triangle is 180°.

For a triangle with equal sides, it implies that each length will possess;

= 180°/3

= 60° each.

Answers

Answer:

86%

Step-by-step explanation:

28 were placed on suspension

200 are total (including that 28)

not placed on suspension are the rest, so 200-28=172

172 out of 200 = 86% not placed on suspension

Answer:

86% Pls consider marking brainliest if correct.

Step-by-step explanation:

Okie lets see

In all : 200

Removed : 28

To find percentage : 200-28/200

200 - 28 = 172

172/200 = (172/2)/(200/2)

I did this because 200 is 100x2, and because percentage is over 100

172/2 = 86

200/2 = 100

86/100 = 0.86 = 86%

Find the area of the shaded region. Round your answer to the nearest tenth if needed.

Answers

Answer:

140 inches

Step-by-step explanation:

Find the area of the square.

4 + 10 = 14 (Length)

11 + 4 = 15 (Breadth/Width)

Area = 14 x 15 = 210 inches

Find the area of the 2 unshaded squares in the square.

Area of square at the top = 4 x 4 = 16 inches

Area of square at the bottom = 6 x 9 = 54 inches

Add the 2 squares of the area together.

16 + 54 = 70 inches

Now deduct the area of the huge box by the area of the 2 unshaded squares.

210 - 70 = 140 inches

Write an
algebraic expression to represent the area of the shaded region:
2y
4y + 3

Answers

Answer:

4y^{2}+3y

Step-by-step explanation:

First you need to distribute the values.

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials

You Should get

8y^{2}+6y

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.

8y^{2}+6y/2

Doing this you will get

4y^{2}+3y

14. A system of equations is shown below. For what value of a will this system have no solutions? Justify your answer.
y = 4x-9
y = ax+6

Answers

Answer:

a = 4

Step-by-step explanation:

a = 4

If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.

Answer:

x can not equal zero, as it would cause division by zero.

Step-by-step explanation:

First, let's make one equation out of them and see what we get. Because both of them have y on the left, we can say that the two right sides are equal, giving us:

4x - 9 = ax + 6

If we solve for a, we get:

ax + 6 = 4x - 9

ax = 4x - 15

a = 4 - 15 / x

With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.

Answer:

yes

Step-by-step explanation:

The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.

5² + 12² = 25 +144 = 169 = 13²

These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.

Yes, AB is a tangent.
