Answer:
F(10) = P(x = 10) = 0.3
F(5) = P(x = 5) = 0.4
F(1) = P(x = 1) = 0.3
Step-by-step explanation:
Given the following :
Probability estimates given:
Very successful = 0.3
Moderately successful = 0.4
Unsuccessful = 0.3
Yearly revenue (X) :
Very successful = $10 million
Moderately successful = $5 million
Unsuccessful = $1 million
The probability mass function of X:
f(x) = probability of each valie of x
When x = 10:
F(10) = P(x = 10) = 0.3
When x = 5:
F(5) = P(x = 5) = 0.4
When x = 1:
F(1) = P(x = 1) = 0.3
Hello!
Add up the costs of everything Kyle purchased and the tax, and then subtract that from $10.
4.95 + 2.30 + 1.10 + 0.65 = 9
10 - 9 = 1
Kyle should have received $1 change.
Answer:
1. Multiply 6 each time. Equation: 6x = y
2. Multiply 15 each time. Equation: 15x = y
Step-by-step explanation:
Check. Let:
Input = x
Output = y
Put the data into the equation given:
Equation: 6x = y
When x = 1; y = 6
6(1) = (6)
6 * 1 = 6
When x = 2; y = 12
6(2) = (12)
6 * 2 = 12
When x = 3; y = 18
6(3) = (18)
6 * 3 = 18
etc.
Check. Let:
Input = x
Output = y
Put the data into the equation given:
Equation: 15x = y
When x = 1; y = 15
15(1) = (15)
15 * 1 = 15
When x = 2; y = 30
15(2) = 30
15 * 2 = 30
When x = 3; y = 45
15(3) = 45
15 * 3 = 45
etc.

The number of strings that can be formed by ordering the letters SCHOOL using some or all of the letters is 1440 strings
<h3>
What is Permutation in Mathematics ?</h3>
Permutation can be defined as number of ways in which things can arranged.
We were given to find how many strings that can be formed by ordering the letters SCHOOL using some or all of the letters.
First of all, How many distinct letters are in the word SCHOOL ?
The distinct letters are 5 in numbers.
What is the total number of letters in the word SCHOOL ?
The total number of letters is 6.
Then
6! + 5
That is, 6 factorial + 6 permutation 5
( 6 x 5 x 4 x 3 x 2 x 1 ) + 6!/( 6 - 5)!
720 + 720
1440 strings
Therefore, the number of strings that can be formed by ordering the letters SCHOOL using some or all of the letters is 1440 strings

Answer:
B. Multiply (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x2 + 11x + 120
Step-by-step explanation:
x is the number of price increases of 0.25 each, so (2 + 0.25x) will be the price after x increases.
2 cups remain unsold for every increase in price, so for x increases, 2x cups remain unsold. Then the number sold is (60 -2x).
Revenue is the product of price and quantity sold, so is ...
... revenue = (60 -2x)(2 +0.25x) . . . . . . matches selections A or B
The product of these binomials is ...
... 60·2 +60·0.25x -2x·2 -2x·0.25x
... = -0.5x² +11x +120 . . . . . . . . . . . . . . . . matches selection B
