Given:
The faces on a number cube are labeled 1,2,2,3,4, and 5.
The number cube is rolled 114 times.
To find:
How many times would you expect the number 2 to appear?
Solution:
We have,
Total outcomes = 1,2,2,3,4, and 5.
Number of total outcomes = 6
Favorable outcomes = 2 and 2
Number of favorable outcomes = 2
The probability of getting 2 is:
Now, the expected number of times when 2 to appear is:
Therefore, the expected number of times is 38.
Answer:
The number of Diplo pops D = 18
The number of sneakers S = 12
Step-by-step expla nation:
Given:
Cost of one Diplo pops = $.50
Cost of one sneakers = $.60
Total number of candies purchased = 30 pieces
cost of the number of candies purchased = $16.80
To Find:
Number of each type of candies = ?
Solution:
Let
The number of Diplo pops be D
The number of sneakers be S
Total number of candies = 30
S+D = 30
S= 30 - D--------------------------------------(1)
and cost of 30 candies is $16.80
S(0.50) + D(0.60) = 16.80----------------(2)
Substituting (1) in (2)
(30 - D)(0.50) + D(0.60) = 16.80
15 - 0.50D +0.60D = 16.80
15 + 0.10D = 16.80
0.10D = 16.80 - 15
0.10D = 1.80
D =
D = 18
So the number of Diplo pops = 18
Number of sneakers S= 30 - 18 = 12
Answer:
Step-by-step explanation:
First, start by converting 4 feet to inches. Note that 1 foot = 12 inches.
Set up a unit converter:
The ft cancel out leaving us with:
Now, we can set up a scale factor...
