Answer:
5/14
Step-by-step explanation:
The total number of cards is 8
There are 5 blue cards
P(1st card is blue) = blue/total = 5/8
We take away a blue card
The total number of cards is 7
There are 4 blue cards
P(2nd card is blue) = blue/total = 4/7
The probability of blue blue is P(blue blue ) =
P(1st card is blue)*P(2nd card is blue) =
5/8* 4/7
20/56
We can divide the top and bottom by 4
5/14

<em><u>Question:</u></em>
Macy, sydmey, and Allie are sisters. macy is two years older than Sydney and Allie is one year less than half the age of sydney. if the sum of their ages is 31, how old is macy
<em><u>Answer:</u></em>
Macy is 14 years old
<em><u>Solution:</u></em>
Let the age of sydney be "S"
Given that,
<em><u>macy is two years older than Sydney</u></em>
Age of macy = S + 2
<em><u>Allie is one year less than half the age of sydney</u></em>
<em><u>The sum of their ages is 31</u></em>
Therefore,
<em><u>how old is Macy?</u></em>
Age of macy = S + 2 = 12 + 2 = 14
Thus macy is 14 years old

Step-by-step explanation:
is product propriety
log AB = log A +log B
1/2 ㏒57 + 1/2 ㏒ 74 = 1/2 ㏒ 57*74 = 1/2 ㏒4,218
and power propriety
log
1/2 log 4,218 = log 4,218^1/2
