There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 of the same colour?

Answer:

I believe not statistical.

Step-by-step explanation:

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).

The 2 and + are out since they don't have variables(and the + is just a +).

So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

Answer:

Slope intercept form is y = mx + b

m is slope

b is y intercept

y = -4/5x + -9

I only know that first one sry

Step-by-step explanation:

Answer:

yes.

Step-by-step explanation:

slope intercept form is y=mx+b

b is the y intercept, m is the slope, and x is x.

for

1. it would be

y= -4/5x -9

2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)

it would look like:

(5- -3) / (3-0) = (8/3)

Then plug in one of the sets of numbers for x and y, to get y intercept.

5=8/3(3)+b

b=-3

So.. slope intercept would be y=8/3x -3

2,912 People

Step-by-step explanation:

12% of 2,600 is 312

add 312 to 2,600

end up with

2,912 People

Answer:

2,912 is the amount of people (population)

Step-by-step explanation:

12% of 2,600 = 312

so

2,600 + 312 = 2,912

[tex]5x^2-7x+9-3x^2+5x\\=5x^2-3x^2-7x+5x+9\\= 2x^2-2x+9[/tex]

Answer:

1 ÷ 2 pounds

Step-by-step explanation:

The computation is shown below:

As we know that

1 pound = 0.454 Kg

Peanut starting weight = 3 ÷ 4 of a pound.

In the case when  the bag is 2/3 full, so the weight is  

= 2 ÷ 3 × 3 ÷ 4

= 1 ÷ 2 pounds

Answer:

1. $16

2.$61.75

3. $222

4.$130

Step-by-step explanation:

1.     20% of $20 is $4.

$20-$4=$16

2.    35% of $95 is $33.25.

$95-$33.25=$61.75

3.    $55.50 divided by 1-.75=222

4.     $78 divided  by 1-.40=130

Hope this helped :)

Answer:

y = 4, 1

Step-by-step explanation:

1) Factor y² - 5y + 4.

[tex](y - 4)(y - 1) = 0[/tex]

2) Solve for y.

Y = 4, 1

Therefor, the answer is y = 4, 1.

Answer and Step-by-step explanation:

To find the length of BC, we will be using the trigonometric function Sine.

The Sine trig function is as follows:

sin(θ) = [tex]\frac{Opposite Side}{Hypotenuse}[/tex]

Plug in the values and solve for the Hypotenuse (BC)

[tex]sin(45) = \frac{8}{x}[/tex]

Multiply x to both sides, then divide both sides by sin(45).

x = [tex]\frac{8}{sin(45)}[/tex]

Input into a calculator and solve.

The length of BC is [tex]8\sqrt{2}[/tex], or 11.3137.

Answer: -1

Step-by-step explanation:

Find the two coordinates first.

In this case, they are (-4, 1) and (-2, -1).

Use the following formula to calculate slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

Substitute in the coordinates:

[tex]\frac{1-(-1)}{-4-(-2)}[/tex] = [tex]\frac{2}{-2}[/tex] = -1

Answer:

c) Circle 5 and 20, 10 and 40, 15 and 60, 20 and 80, and 25 and 100. When you multiply the top by 4, they all equal the bottom values.

d) The bottom compares to the top terms because you can divide them by 4 and they'll equal the top terms

3 3/5 of a punnet of strawberries(mixed Number)

Step-by-step explanation:

Mimi = 9/10 of a punnet of strawberries

Jamie has four times as many strawberries as Mimi

Jamie = 9/10 × 4

= (9×4) / 10

= 36/10

= 3 6/10

= 3 3/5 of a punnet of strawberries

Jamie = 3 2/5 of a punnet of strawberries

Answer:

area = m²/2π

Step-by-step explanation:

∵ circumference of circle = 2πr = m

∴ r = m/2π

∵ area of circle = πr²

∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π
