Probability helps us to know the chances of an event occurring. The number of black, blue, green and red marbles in the bag are 4, 3, 2, and 1 respectively.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given Joanne has 10 marbles in a bag. Also, she does an experiment whose results are as follows:

The number of black marbles in the bag is equal to the product of Probability of getting a black marble and the number of marbles. Therefore,

The number of black marbles = (24/60)×10 = 4

The number of blue marbles in the bag is equal to the product of Probability of getting a blue marble and the number of marbles. Therefore,

The number of blue marbles = (18/60)×10 = 3

The number of green marbles in the bag is equal to the product of Probability of getting a green marble and the number of marbles. Therefore,

The number of green marbles = (12/60)×10 = 2

The number of red marbles in the bag is equal to the product of Probability of getting a red marble and the number of marbles. Therefore,

The number of black marbles = (6/60)×10 = 1

Hence, the number of black, blue, green and red marbles in the bag are 4, 3, 2, and 1 respectively.

Answer:

y=-1/2*+5

Step-by-step explanation:

Answer:

x = C - By over A

Step-by-step explanation:

To solve for x, we need to isolate the variable.

Ax + By = C

Focusing on the left side of the equation (this is to isolate x), we can see that By is the farthest from x, and that it's adding. So we subtract from both sides. The -By would cancel out +By, which would leave us with.

Ax = C - By

Here we see that A is multiplying x, opposite of multiplication is division, so we divide both sides by A, which would give us:

x = C - By over A

Answer:

[tex]\boxed {\boxed {\sf a \approx207.35 \ in^2}}[/tex]

Step-by-step explanation:

Since the central angle is given in degrees, we should use this formula to find the area of the sector:

[tex]a=\frac{\theta}{360} \times \pi r^2[/tex]

The central angle is 165 degrees and the radius is 12 inches.

Substitute the values into the formula.

[tex]a= \frac{165}{360} \times \pi (12 \ in)^2[/tex]

Solve the exponent.

[tex]a= \frac{165}{360} \times \pi(144 \ in^2)[/tex]

Multiply all the numbers together.

[tex]a= 207.345115137 \ in^2[/tex]

Round to the nearest hundredth (two decimal places).

The 5 in the thousandth place (in bold above) tells us to round the 4 in the hundredth place up to a 5.

[tex]a \approx207.35 \ in^2[/tex]

The area of the sector is approximately 207.35 inches squared.

Answer:  $18.19.

You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.

Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

Step-by-step explanation:

The equivalent equation is (x - 3)² = 17

The equation given is :

x² - 6x = 8

The equation is a quadratic equation

A quadratic equation is an equation that has one variable that is raised to the power of 2.

it is usually in the form : ax² + bx + c = 0  

a, b,c are known numbers

x is unknown

To determine which option is correct, we are to solve for each of the options to see which is correct

1. (x - 6)² = 44

(x -6)(x -6) = 44

x² - 6x -6x + 36 = 44

x² -12x + 36 = 44

x² - 12 = 8

The first option is not correct

2. (x - 3)² = 14

(x -3)(x -3) = 14

x² - 3x -3x + 9 = 14

x² -6x + 9 = 14

x² - 6x = 5

the second option is not correct

3. (x-6)² = 20

(x -6)(x-6) = 20

x² -6x -6x + 36 = 20

x² -12x = -14

the third option is not correct

4. (x - 3)² = 17

(x-3)(x - 3) = 17

x² - 3x - 3x + 9 = 17

x² - 6x = 8

The fourth option is correct

Step-by-step explanation:

Data: $50 to rent the Skate Center

$5.50 for each person who attends

Limit of spending: $300

How many people can attend=x

Step one, Make the equation

$5.50x+$50=$300

Reason: Since we know that amount of people(x) multiplied by $5.50 added to $50 will get us $300, we can make an equation from that. The equation will make the problem simpler to solve.

Step two, Start isolating x by subtracting $50 on both sides

$5.50x+$50-50=$300-50=$5.50x=$250

Reason: Since we have to find x, we have to isolate it. The first step in doing that is subtracting $50 by 50 to get rid of it. However, since what you do to one side, you do to the other, you have to subtract $300 by 50 to get $250.

Step three, Divide by 5.50 on both sides

$5.50x/5.50=$250/5.50=x=45.454545454-

Reason: Since we have to isolate x and 5..50 is being multiplied by x, you have to divide it by 5.50 to get rid of 5.50. What you do to one side, you do to the other so you divide 250/5.50 to get 45.4545454545-.

Since this is a irl problem, you have to round it to 45 people

Answer:

m<SQP=124°

Step-by-step explanation:

Hi there!

We're given ΔQRS, the measure of <R (90°), and the measure of <S (34°)

we need to find m<SQP (given as x+72°)

exterior angle theorem is a theorem that states that an exterior angle (an angle on the OUTSIDE of a shape) is equal to the sum of the two remote interior angles (the angle OUTSIDE of a shape will be equal to the sum of 2 angles that are OPPOSITE to that angle).

that means that m<SQP=m<R+m<S (Exterior angle theorem)

substitute the known values into the equation

x+72°=90°+34° (substitution)

combine like terms on both sides

x+72°=124° (algebra)

subtract 72 from both sides

x=52° (algebra)

however, that's just the value of x. Because m<SQP is x+72°, add 52 and 72 together to get the value of m<SQP

m<SQP=x+72°=52°+72°=124° (substitution, algebra)

Hope this helps!
