Wer +266. A bag contains $3$ balls labeled $2, 4$ and $8$. A ball is to be picked, the value on the label is to be recorded and then the ball is to be returned to the bag. This will be done three times and then the values will be added together. What is the sum of all of the possible distinct sums?
Answer:
The sum of all the possible distinct sum is 128
Step-by-step explanation:
The number of balls in the bag = 3
The ball labels, (the numbers written on the balls) = 2, 4, and 8
The number of balls selected with replacement = 1
Therefore, we have have, the number of ways of selecting 1 ball from 3 = 3 ways
The distinct combination of the selected balls are;
2, 2, 2 with sum 2 + 2 + 2 = 6
2, 2, 4 with sum 2 + 2 + 4 = 8
2, 2, 8 with sum 2 + 2 + 8 = 12
2, 4, 4 with sum 2 + 4 + 4 = 10
2, 4, 8 with sum 2 + 4 + 8 = 14
2, 8, 8 with sum 2 + 8 + 8 = 18
4, 4, 4 with sum 4 + 4 + 4 = 12
4, 4, 8 with sum 4 + 4 + 8 = 16
8, 8, 4 with sum 8 + 8 + 4 = 20
8, 8. 8 with sum 8 + 8 + 8 = 24
The distinct sums are therefore;
6, 8, 12, 10, 14, 18, 16, 20, 24
The sum of the distinct sum is 6 + 8 + 12 + 10 + 14 + 18 + 16 + 20 + 24 = 128.
Answer: 128
Step-by-step explanation:
Any sum formed by a combination of the numbers 2, 4, 8 and must be divisible by 2. The smallest possible value of such a sum is equal to 3*2=6 , and the largest possible value of such a sum is equal to 3*8=24 . After testing, we find that
6 = 2+2+2, 8=4+2+2, 10=4+4+2
12 = 4+4+4, 14 = 8+4+2, 16 = 8+4+4
18 = 8+8+2, 20 = 8+8+4, 24 = 8+8+8
However, we cannot find a combination that will add to be 22: if two of the numbers are not 8, then the maximum possible sum is 4+4+8 = 16. Thus, two of the numbers picked must be 8, but then the third ball must have the number 6, which is not possible. Thus, the answer is the sum of the even numbers from 6 to 24 excluding 22, which is 128 .

Suppose that you own a compact car
that you bought new for 18,000 dollars.
The value of this particular make of car is
known to depreciate at a rate of 20%
per year.
Define a unit for each quantity in the
worksheet. Then enter a variable for
the time since you bought the car new
Answer:
Depreciation and Written Down Value for first 5 years of purchase is explained.
Step-by-step explanation:
The Car was purchased for $18000 this will be depreciated at a rate of 20% per year.
Declining Method
Year 1
$18,000 * 20% = $3,600 Depreciation
$18,000 - $3,600 = $14,400 Written Down Value WDV
Year 2
$14,400 * 20% = $2,880 Depreciation
$14,400 - $2,880 = $11,520 WDV
Year 3
$11,520 * 20% = $2,304 Depreciation
$11,520 - $2,304 = $9,216 WDV
Year 4
$9,216 * 20% = $1,843 Depreciation
$9,216 - $1,843 = $7,373 WDV
Year 5
$7,373 * 20% = $1,475 Depreciation
$7,373 - $1,475 = 5,898 WDV

What is the area of the triangle?
A. 8.64 ft2
B. 10.8 ft2
C. 14.4 ft2
D. 17.28 ft2
Answer: 8.64
Step-by-step explanation:
3.6 * 4.8 = 17.28
17.82/2 = 8.64
Answer:
A. 8.64 ft²
Step-by-step explanation:
The equation for the area of a triangle is A = 1/2bh
b is base and in this case 4.8
h is height and in this case 3.6
A = 1/2 (3.6)(4.8)
A = 8.64

The measure of the angle x in the right triangle is 67 degrees.
How to find the angle of a right triangle?A right angle triangle has one of its angles as 90 degrees.
The sum of angle in a triangle is 180 degrees.
Therefore,
x + 90 + 23 = 180
x + 113 = 180
x + 113 - 113 = 180 - 113
x = 67°

WHO WANTS BRAINLIESTT ?????? PLEASE answer this question correctly !!!! STEP BY STEP !!!!!!!!!!!!!!!
Answer:
x = 45
y = 60
Step-by-step explanation:
2x = 90
2x (1/2) = 90 (1/2)
x = 45
3y - 2y = 90
3y - 2(45) = 90
3y - 90 = 90
3y - 90 (+90) = 90 (+90)
3y = 180
3y (1/3) = 180 (1/3)
y = 60

Find the value of x. Give reasons to justify your solution-
Answer:
x = 34
Step-by-step explanation:
∠ PSR and ∠ TSU are vertical angles and congruent, then
∠ PSR = 4x, thus ∠ PSQ = x
The exterior angle of a triangle is equal to the 2 opposite interior angles.
∠ SQR is an exterior angle of Δ PQS , thus
x + x = 68
2x = 68 ( divide both sides by 2 )
x = 34
Answer:
X = 34°
Step-by-step explanation:
In order to solve this question we will need to know the following, when two lines intersect the opposite angles at that point are equal to each other, that the sum of all angles of a triangle is 180 degrees, and that the angle of a straight line is equal to 180 degrees.
Frist we will have to notice that ∠TSU is equal to ∠PSR, because they are opposite to each other (If you would like to understand this more you can research on a topic call "vertical angels"). Now it is important to understand the following.
∠PSR = ∠PSQ + QSR
Since ∠PSR = ∠TSU = 4x, ∠QSR = 3x ⇒
⇒ ∠PSR = ∠PSQ + QSR
4x = ∠PSQ + 3x
4x - 3x = ∠PSQ
x = ∠PSQ
Now, since the sum of all angles in a triangle is equal to 180 we can now say the following:
∠QPS + ∠PSQ + ∠PQS = 180°
In order to find out what PQS is equal to we need to use our knowledge about the angel of a strait line (the angel of a strait line is equal to 180°).
So now we can say the following:
180° = ∠PQS + SQR
∠PQS = 180° - ∠SQR
Since we know that ∠SQR = 68° ⇒
⇒∠PQS = 180° - ∠SQR
∠PQS = 180° - 68°
∠PQS = 112°
Since ∠QPS = x, PSQ = x, and ∠PQS = 112° ⇒
⇒ ∠QPS + ∠PSQ + ∠PQS = 180°
x + x + 112° = 180°
2x = 180° - 112°
2x = 68°
x = 34°

Angle WXY underwent a sequence of two rotations around different centers. The original size of WXY is 82°. what is the size of the angle after the sequence of rotations?
Given:
[tex]\angle WXY=82^\circ[/tex]
It underwent a sequence of two rotations around different centers.
To find:
The size of the angle WXY after the sequence of rotations.
Solution:
We know that, rotation is a rigid transformation. It means, the size and shape of the figure remains the same after the rotations. It other words, the figure and its image are congruent after rotation.
So, the measure of angle WXY remains same after the sequence of rotations, i.e.,
[tex]\angle W''X''Y''=82^\circ[/tex]
where, [tex]\angle W'X"Y"[/tex] is the image of [tex]\angle WXY[/tex] after the sequence of rotations.
Therefore, the size of the angle WXY after the sequence of rotations is 82°.

Which describes dependent events?
drawing a blue marble and a yellow marble at the same time from a bag of marbles
drawing the ace of spades from a deck of cards, putting it back into the deck, and
drawing the king of spades.
rolling a six-sided number cube and getting an even number, then rolling the same six-sided number cube and getting an even number again
flipping two coins at the same time and getting heads on one and tails on the other
Answer: Drawing a blue marble and a yellow marble at the same time from a bag of marbles is the example of dependent events.
Step-by-step explanation: When the cards are replaced, or flipping coins or rolling dice, the outcome of the first event does nor affect the probability of the next event.
Drawing two marbles at the same time is essentially the same as drawing one and Not replacing it and then drawing the second one. The number of marbles left affects the probability.

I NEED HELP!!! What is is this ----> 3x - 3y = 3 12x + 8y = -8
x = what
y = what
Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6
