Multiples of 11 between 1 and 30:

11, 22

So there are 2 numbers that are multiples of 11 in the bin. There are a total of 30 cards, so the probability is written as 2/30. Or we can simplify it to 1/15.

For the next question:

There are a total of 3 + 8 = 11 balls in the bag.

The probability of choosing a red ball is 3/11.

The probability of choosing a green ball is 8/11.

Multiply the three fractions:

3/11 * 3/11 * 8/11 = 72/1331

So the probability is 72/1331.

For the last question:

A standard deck of cards has 52 cards.

There are 4 queens and 4 kings in the deck.

Probability of choosing a queen is 4/52, and the probability of choosing a king AFTER you already chose a queen is 4/51.

Multiply the two fractions:

4/52 * 4/51 = 16/2652

So the probability is 16/2652 or 4/663

Can someone please help, will give the brainiest.

Studentka2010 [4]

Answer:

Step-by-step explanation:

As it is supposed to be linear, we just subtract two adjacent months to find the difference.

$13,849.60 - $13,610.81 = $238.79 which will be her monthly payment (Q 14)

December's balance is $13,610.81 - $238.79 = $13,372.02 (Q13)

At the end of September, her first payment, her balance was

$13,849.60 + $238.79 = $14,088.39 and her original purchase price was

$14,088.39 + $238.79 = $14,327.18

so an equation for the current balance B at any month m is

B = (-$238.79)m + $14,327.18

We verify this by testing for February

B = (-$238.79)6 + $14,327.18 = $12,894.44 which checks out

It will take 14327.18 / 238.79 = 60 months to pay it off or 5 years (Q 15)

Which graph correctly represents 1/3y-1/2x>2 ?

Tanzania [10]

<span>Put it in the form of y =mx +b, or in this instance, y> mx +b
move the (1/2) x to the right by adding it to both sides of the inequality
(1/3)y>(1/2)x +2
Multiply by 3 on both sides to get y by itself.
y>(3/2) x +6
This is a graph with y intercept of (0,6) and a moderate upward and to the right slope. Because it is > , the line on the graph will NOT be part of the solution.

The easiest way to find the side of the graph that the inequality satisfies is to use (0,0) and see if it works or doesn't work. In the original equation, 0-0>2 does NOT work, so the area where the inequality works is to the up and left of the graph, which should be a dotted line to show that the inequality is greater than only.
The point (6,-2) should work.
Test it. 6*(1/3)-(-2)*(1/2)>0 ; 2-(-1)=3, and 3>2 It does work.
The point (6,2) should not work
Test it. 6 *(1/3)-2(1/2)=2-1 ; 1 is NOT >2, so it does not work.
If the graph goes through the origin, then pick a point near the graph with a small x or y.</span>
