A fair spinner has 9 equal sections: 3 red, 4 blue and 2 green.
It is spun twice.
What is the probability of getting red both times?

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

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.

The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, Amir has 48 ounces of cashews, walnuts, and pecans.

He adds x ounces of peanuts to create a mixture.

M(x) that represents the number of ounces of all nuts in the mixture.

M(x)=48

N(x) that represents the number of ounces of peanuts in the mixture.

So, N(x)=x

Now, (M/N)(x) = M(x)/N(x)

= 48/x

Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

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

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:

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
