Answer 6

Alfred draws candles randomly from a pack containing 4 colored candles of the same shape and size. There are 2 red candles, 1 green candle, and 1 blue candle. He draws 1 candle and then draws another candle without replacing the first one. Find the probability of picking 1 red candle followed by another red candle, and show the equation used.



The probability of picking 1 red candle followed by another red candle is 1/12.


1/4 times 1/3 = 1/12

Answer 7

I think that the requested probability is given by the multiplication of those probability, namely
1/2 * 1/3 = 1/6

Answer 8

fan and medal

Answer 15

`There are 2 red candles, 1 green candle, and 1 blue candle`

2+1+1 = 4 candles total

--------------------------

The probability of picking one red candle is (# of red)/(# total) = 2/4 = 1/2

After that first one is picked, there is 1 red candle left out of 3 candles total

so the probability of picking another red candle is (# of red left)/(# total left) = 1/3

--------------------------

So that's how harryhart got his numbers and why the answer is (1/2)*(1/3) = 1/6

Answer 16

A bag has 1 red marble, 4 blue marbles, and 3 green marbles. Peter draws a marble randomly from the bag, replaces it, and then draws another marble randomly. What is the probability of drawing 2 blue marbles in a row? Explain your answer.

@jim_thompson5910

Answer 17

tell me what you have so far

Answer 18

told you is 1/6

Answer 19

The probability of drawing 2 blue marbles in a row is 1/64. 1/8 times 1/8 = 1/64. @jim_thompson5910

@LynFran

Answer 22

am i correct?

Answer 23

plz somebody help!

Answer 24

Hint: there are 4 blue marbles out of 4+3+1 = 8 marbles total. The probability of drawing one blue marble is 4/8 = 1/2. Use this to figure out the probability of drawing 2 blue marbles.

Answer 25

1/64 is not correct

Answer 26

1/2 times 1/2 = 1/4

is the answer 1/4?

Answer 27

do 4/8*4/8

Answer 28

yes, 1/4 is the answer

Answer 29

Greg has 4 shirts: a white one, a black one, a red one, and a blue one. He also has two pairs of pants, one blue and one tan. What is the probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants? Show your work.

my answer:

The probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants is 1/8.

1/4 times 1/2 = 1/8
1/4=probability of picking a white shirt
1/2 = probability of picking tan pants

Answer 31

very nice

Answer 32

you have the right answer

Answer 33

can u help me with more please?

Answer 34

sure

Answer 35

Galvin and Henry spend a certain amount of money from their money box each month to buy plants. The table (function 1) shows the relationship between the amount of money (y) remaining in Galvin’s money box and the number of months (x):


Number of Months
(x)

Amount Remaining (in $)
(y)

1

80

2

75

3

70

4

65



The equation (function 2) shows the relationship between the amount of money, y, remaining in Henry’s money box and the number of months, x:

Function 2
y = −7x + 80

Which statement explains which function shows a greater rate of change?
Function 2 shows a greater rate of change, because Henry spends $7 each month and Galvin spends $5 each month.
Function 2 shows a greater rate of change, because Henry spends $80 each month and Galvin spends $15 each month.
Function 1 shows a greater rate of change, because Galvin spends $15 each month and Henry spends $73 each month.
Function 1 shows a greater rate of change, because Galvin spends $5 each month and Henry spends −$7 each month.

i think it is A

Answer 36

let me think

Answer 37

chart=

1 80
2 75
3 70
4 65

Answer 38

sorry it turned out in a straight line

Answer 39

ok that makes more sense now

Answer 40

A is correct. The slope of function 1 is -5 which means he spends $5 a month. The slope of function 2 is -7 meaning that he spends $7 a month

Answer 41

What about: Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.

y = 9x

Part A: How many more dollars is the price of a box of Luke’s original brand of cereal than the price of a box of the super-saving brand? Show your work.

Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work.



im gonna do it and post what i get for my answer. can u solve now and check my answer when i post?

Answer 42

ok

Answer 43

Part A: Luke's original brand of cereal costs $2 more than the price of the super-saving brand.

original brand: y = 11x
super-saving brand: y = 9x
11x - 9x = 2x
2x = amount saved per box



Part B: Luke saves $12 each month with the change in cereal brand if he buys 6 cereal boxes each month because:

$2x times 6 boxes = $12 saved
$2x = money saved per box
6 = boxes bought per month

Answer 44

both parts are correct

Answer 45

you don't need the 2x in part A. They just want the price difference for one box. Although, you can use that equation and plug in x = 1

Answer 46

so I guess it works out

Answer 47

yay! thanks so much. r u available to do a few more?


and also is it okay if i leave the x in 2x or should i take it out? my class is for FLVS

Answer 48

i think i should leave it just in case

Answer 49

well again, part A was for one box only so if it were me, i'd say 11 - 9 to keep it simple

Answer 50

but you can go with 11x - 9x = 2x and plug in x = 1. It's the same idea just more work

Answer 51

its an advanced course. so i should just leave it? i think it would be okay if i left it no?

Answer 52

yeah that's fine then
