Answer: The required expected value is $3.46.
Step-by-step explanation:
Since we have given that
Number of value of 4 or less are
2,3,4
So, there are 12 in numbers.
So, probability would be
Since Aces are considered as the highest card in the deck.
So, remaining probability would be
Amount paid or value of 4 or less = $165
Amount not paid for other case = $45
So, the expected value would be
Hence, the required expected value is $3.46.
Answer:
-2
Step-by-step explanation:
-|3n| - 2 = 4
|3n| = -6
3n = -6 or 3n = -(-6)
n = -2 n = 2
Since 2 is not part of the options, -2 is the only correct answer
12 dogs to 92 cats.
12/92
Both 12 and 92 are divisible by 4.
12/4=3
92/4=23
Simplified ratio: 3/23
There are 3 dogs for every 23 cats.
<span>When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.</span>
