What is the diameter of a circle if the circumference is 18.84?

Answer:

The probability that it is a red or black marble is 0.6429, or 64.29%

Step-by-step explanation:

Frequentist Probability

The probability of an outcome is defined as the frequency of the number of ways the outcome occurs relative to the number of ways that it could have occurred.

The equation to calculate the probability is:

[tex]\displaystyle P(A)=\frac{m}{n}[/tex]

Where m is the number of ways the event A can occur and n is the total number of ways it could have occurred.

The bag contains 6 red, 5 yellow, and 3 black marbles. If one of them is randomly selected, it can be of any color from a total of n=6+5+3=14

Event A consists of the marble being red or black. It can be taken from m=6+3=9 marbles.

The probability is:

[tex]\displaystyle P(A)=\frac{9}{14}=0.6429[/tex]

The probability that it is a red or black marble is 0.6429, or 64.29%

Answer:

243

Step-by-step explanation:

Let s be the number of students in the school

2/9 of the students are in 6th grade

2/9 *s = 54

Multiply each side by 9/2

9/2 * 2/9 * s= 54 * 9/2

s =243

Answer:

s = 6

Step-by-step explanation:

We know a square has all equal side lengths. So we would divide the square by four to get one side length.

24/4 = 6

s = 6

[tex]C = \frac{1}{4}n( \: a(1) \: + \: a(2) \: ) \\ [/tex]

Multiply sides by 4

[tex]4 \times C = 4 \times \frac{1}{4}n( \: a(1) + a(2) \: ) \\ [/tex]

[tex]4C = n( \: a(1) + a(2) \: )[/tex]

Divided sides by n

[tex] \frac{4C}{n} = \frac{n}{n}( \: a(1) + a(2) \: ) \\ [/tex]

[tex] \frac{4C}{n} = a(1) + a(2) \\ [/tex]

Subtract sides - a (2)

[tex] \frac{4C}{n} - a(2) = a(1) + a(2) - a(2) \\ [/tex]

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

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

Answer:

Option (4)

Step-by-step explanation:

Mass of Mercury = 3.3 × [tex]10^{23}[/tex] kg

Mass of Mars = 6.42 × [tex]10^{23}[/tex] kg

Therefore, ratio of the masses of Mars and Mercury = [tex]\frac{6.42\times 10^{23} }{3.30\times 10^{23}}[/tex]

                                                                                       = 1.95

[tex]\frac{\text{Mass of Mars}}{\text{Mass of mercury}}=1.95[/tex]

Mass of Mars = 1.95 × (Mass of Mercury)

Therefore, mass of Mars is .95 times more than Mercury.

The number line

It's a graphic representation of the real numbers, usually centered at the value 0 and where the positive numbers running to the right, the negative numbers running to the left.

The product (-4)(-2)(-1) can be operated by multiplying the signs apart from the magnitudes. Recall an odd number of negative signs results in a negative number:

(-) * (-) * (-) = -

The product of the magnitudes is 4*2*1=8. Thus the result is -8.

im not entirely sure if its correct but

A: 384 in.

B: 1040 in. = 86 ft

C: The perimeter for the actual flower bed is converted into feet because the dimensions are multiplied by 26 inches.

Answer:

I’m not gonna show you a graph but these instructions should help…

For the first equation.
You have

5y = -3x + 15

So we have to put it in y=mx + b format.

We can isolate y.
Divide 5 on both sides.

y = -3/5 x +3

You have your equation right htere.

The y intercept (b) here is 3 following the format y=mx +b

So now you plot a point on (0,3) since thats your Y- intercept, first point of contact on the y axis. Now for the slope. Slope goes by rise / run. Think of it as you get out of bed, you have to get up first before you run off to whatever you do.

Now you can just follow the instructions give, -3/5 is -3 rise and 5 run. Since a -3 rise is going down, we do down since its a negative slope here.
Starting from (0,3) you go down 3 units, then at that point go to the RIGHT 5 units. You should have a plotted point on, (5,0). Now following the postulate, if two lines exists in a plane that a line is created, draw a line using the 2 points from (0,3) to (5,0). (Draw throguh the whole thing, not segment and make sure it fills up the whole coordinate plane)

That is your equation.

For the second equation its the same thing, but this time it’s an inequality.
It’s the same gist and the equation is already simplified due for you!

Start on the y- intercept which is -2, or (0,-2)

Now since it’s a positive slope, because its 1/2, rise 1, run 2. From (0,-2) rise up 1 and then run two units to the RIGHT.
You should end up with, (2, -1)

Construct a line throught he two points (not segment line, fill the whole plane).

Now since its an inequality, we don’t stop there.

It’s a less then sign so when constructed the line that fills the whole plane.

You have to shade the bottom RIGHT of your screen that has a line throguh it.
So basically a line is made though two points and you have the whole plane covered. Shade in the bottom part WITHOUT crossing over the line.

Answer:

[D] (2,1)

Step-by-step explanation:

Given;

y=2x-3

y=-2x + 5

Solve;

y = 2x - 3 . . . [Equation 1]

y = -2x + 5 . . . [Equation 2]

[Equating 1  and 2]

2x - 3 = -2x + 5

2x + 2x = 5 + 3

4x = 8

x = 8/4 = 2

x = 2

y = 2(2) - 3 = 4 - 3 = 1

y = 1

Solution = (2, 1)

Hence, Answer = [D] (2,1)

Answer:

20%

Step-by-step explanation:

To solve, we can calculate how much 1,600,000 is of 8,000,000 as a decimal and then solve from there.

Let's say our missing value is x.

x of 8,000,000 = 1,600,000

"x of something", in this case, can be rephrased as "x * something", so we have

x * 8,000,000 = 1,600,000

divide both sides by 8,000,000 to isolate x

x = 1,600,000/8,000,000 = 0.2

to convert from a decimal to percentage, multiply by 100

0.2 * 100 = 20

20% is our answer
