What is the probability of drawing two yellow marbles if the first one is NOT placed back into the bag before the second draw?

Answer:

your answer is 9

Step-by-step explanation:

a+b(c)

7+4(1/2)

7+2=9

Answer:

Answer

Correct option is

D

all of the above

For any two rational numbers a and b,  

(a+b),(a−b),(b−a) & (a×b) are all rational numbers.

Thus, rational numbers are closed under addition, subtraction and multiplication. (for the first one)

Answer:

The sum of x and y is a rational number

Step-by-step explanation:

X+Y or 5+7=12

A rational number is any number that can be divided without going on and on forever. (for the 2nd one )

Answer:

900

Step-by-step explanation:

First, we set up our equation: To find the area of a trapaziod, the equation is Base 1+ Base 2 times Height

So, the equation would be: A=26+46x19

A=72x19

72 times 19= 900

Hope this helps and have a nice day!

Answer:

To find the perimeter of a polygon, you just have to add the values of each side.

For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

Answer:

0.5

Step-by-step explanation:

the sum of the probabilities of the outcome should equal 1

Probability the outcome is not A = sum of probabilities of the outcome - probability the outcome is A

1 - 0.5 = 0.5

Answer:

B

Step-by-step explanation:

Answer:

A. (5 1/2x2)+(2 1/4x2)=x

x=15 1/2

B. 5 1/2 x 2 1/4= 12 3/8

Answer:

90 km/h

Step-by-step explanation:

To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.

Answer:

height (h) = 15

Step-by-step explanation:

To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

Answer:

a)50%,b)70%

Step-by-step explanation:

odd=5

10=100%

5×100=500/10

=50%

10=100%

(7×100)/10=70

Answer:

The information we have is:

The boat can hold 170 L of fuel

The boat uses 34L each hour.

With this information, we can find the total amount of time that the boat can be used.

If the boat is used x hours, then it needs:

x*34L of fuel.

And the maximum amount of fuel that the boat can use uis170 L

Then we can solve:

x*34L = 170L

Now we can divide both sides by 34L to isolate x.

x = 170L/34L = 5

This means that the boat can be used for 5 hours.

Answer:

The leading coefficient, a.

Step-by-step explanation:

In a quadratic equation:

y = a*x^2 + b*x + c

The leading coefficient is the coefficient hat that multiplies the variable with the highest power.

In this case, is easy to see that the leading coefficient is a.

We call this the "leading" coefficient because is the coefficient that most impact has on the equation's behavior.

In the case of the quadratic equation, we know that x^2 is always a positive number and is the part that grows faster.

Then if a is a positive number, a*x^2 will be positive, and because this is the part that grows faster, the arms of the parabola will open upwards.

If a is negative, then a*x^2 will be negative, and this will cause that the arms of the parabola open downwards

Then the sign of a defines the direction of the parabola.

And a also defines the width of the parabola.

If a is a really larger number, then

a*x^2 grows really fast

This means that in a small increase of x, we may see a large increase in y, so we will have a "thin" parabola.

On the other hand, if a is really small, a large increase of x will not cause a large increase on y, so we will see a wider parabola.

Then the coefficient a (or variable, depending on which thing are you changing) is the one that controls the parabola's direction and width.

Answer:

Indian system of numeration:

With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.

For instance, a million would be:

= 10,00,000

Distance to moon in Indian numeration = 3,84,014 km

International System of Numeration:

Here a comma separates a maximum of 3 digits. A million here would be:

= 1,000,000

Distance to moon is therefore:

= 384,014 km
