Answer:
1/40
Step-by-step explanation:
Probability: (number of ways to achieve the desired result / number of possible results)
For example, if we want a coin to land on heads:
We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.
Using this, we know that there are 5 grey marbles (the desired result) and there are (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:
5 / (5 + 3 + 6 + 2 + 4) =
5/20 =
1/4
We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10
To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.
1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.
Answer:
3 1/3 cups
Step-by-step explanation:
one and one half dozen = 1.5 * 12 = 18 cookies
18 cookies 90 cookies
---------------- = -------------
2/3 cup x cups
using cross products
18 * x = 2/3 * 90
18 x = 60
divide each side by 18
x = 60/18
divide top and bottom by 6
x = 10/3
change the improper fraction to a mixed number
3 goes into 10 3 times with 1 left over
x = 3 1/3 cups
Answer:
$5.19
Step-by-step explanation:
All you do is divide $25.95 BY 5
<span>The
temperature of dry ice is −109.3°f−109.3°f. this is 184.9°f184.9°f less
than the outside temperature. write and solve an equation to find the
outside temperature tt (in degrees fahrenheit).
= </span>175°f
Sure !
At 5 PM, it was 7.1° .
Then the sun went down, a cold front moved in,
and the temperature started dropping.
It dropped from 7.1° down to zero, and it didn't stop there.
It kept on dropping some more.
After it went down to zero, it dropped another 10.3° .
All together, it dropped 7.1° plus 10.3° .
