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

1) Write an absolute value equation that is reflected, vertically shifted 2/3 units down and 1/2 units to the right.
SSSSS [86.1K]

Question 1) Write an absolute value equation that is reflected, vertically shifted 2/3 units down and 1/2 units to the right.

Answer 1):

We know that absolute function is given by y=|x|

reflection happens when we multiply by negative sign so we get

y=-|x|

To get vertical shift down, we subtract so new equation is

y=-|x|-2/3

To get right shift by h unit, we replace x by (x-h) so the new equation is

y=-|x-1/2|-2/3

Hence final answer is

y=-\left|x-\frac{1}{2}\right|-\frac{2}{3}


Question2) Write an absolute value equation with a horizontal shift 4 units to the right.

Answer:

We know that absolute function is given by y=|x|

To get horizontal right shift by h unit, we replace x by (x-h) so the new equation is

y=|x-4|

Hence final answer is y=|x-4|.

What is the measure of A
Rainbow [258]

Given:

A figure of a triangle.

To find:

The measure of angle A.

Solution:

Label the points in the figure as shown below.

In the below figure,

\angle ACB\cong \angle DCE            (Vertically opposite angles)

m\angle ACB=m\angle DCE              (Congregant angles)

m\angle ACB=8x+4

Using exterior angle theorem in triangle ABC, we get

m\angle A+m\angle C=\text{Exterior }m\angle B

m\angle BAC+m\angle ACB=130^\circ

(3x-6)+(8x+4)=130^\circ

11x-2=130^\circ

Isolate the variable term x.

11x=130^\circ+2

11x=132^\circ

x=\dfrac{132^\circ}{11}

x=12^\circ

Now, the measure of angle A is:

m\angle A=3x-6

m\angle A=3(12^\circ)-6

m\angle A=36^\circ-6

m\angle A=30^\circ

Therefore, the correct option is B.
