Suppose you choose a marble from a bag containing 6 red marbles , 2 white marbles and 5 blue marbles you return the first marble

algol [13]

Answer:

30/169

Step-by-step explanation:

We need to know how many marbles in the bag

6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles

P (red) = red / total = 6/13

We then put the marble bad so there are still 13 marbles in the bag

P(blue) = blue /total = 5/13

P (red then blue ) = P(red) *P(blue)

= 6/13 * 5/13 = 30/169

mylen [45]

Answer: $0.4862\ \text{Pounds}$

Step-by-step explanation:

Given

Weight of a newborn baby is $2.2\times 10^{-1}\ \text{pounds}$

If an adult panda weighs up to 1.2103 times more than a newborn panda

Then weight of an adult is given by

$\Rightarrow 2.2\times 10^{-1}+2.2\times 10^{-1}\times 1.2103\\\Rightarrow 2.2\times 10^{-1}+2.6626\times 10^{-1}\\\Rightarrow 0.4862\ \text{Pounds}$

HACTEHA [7]

Answer:

sells 2500 candies per month

Step-by-step explanation:

m = mints

a = almond bar

c = caramels

m = 3a

1/2 c = a

m = 3750

3a = m

a = m/3

a = 3750/3

a = 1250

1/2 c = 1250

c = 2 * 1250

c = 2500
