Answer:
twice
Step-by-step explanation:
to find expected value multiply probablility and number of events
0.40 times 5 = 2.0
Answer:
42 times.
Step-by-step explanation:
The number of total alphabet = 26 tiles
The number of vowels = 5
The number of consonant = 26 - 5 = 21
Sofia will randomly select 1 tile from the bag and without replacement select another tile from the bag.
The probability to select consonant at first time = 21/26
Total tiles after the first selection = 26 - 1 = 25
The probability to select vowels at second time = 5/25
The probability to select consonant and vowels = 
Sofia will draw two tiles from the bag 260 times.
The prediction for the number of times Sofia will select a consonant tile and a vowel tile = 
#64
Let x represent the time spent for valleyball
Then swimming will be 2x
x + 2x = 4.5
3x = 4.5
x = 4.5/3
x = 1.5
Time spent on valleyball: 1 1/2 hours
Time spent on swimming: 3 hours
The solution to the given equation is 4 and -4.

Hey there! I'm happy to help!
To find the number halfway between two numbers, you simply add them and then divide by two.
1.4142133+1.41422=2.8284333
2.8284333/2=1.41421665
That is one number in between these two. Now, we can find the number in between the middle number and the second number. This is another number in between our two numbers.
(1.41421665+1.41422)/2=1.414218325
You could keep on doing this and find tons of numbers in between these two.
Therefore, two numbers between 1.4142133 and 1.41422 are 1.41421665 and 1.414218325.
Have a wonderful day! :D
