Answer:
Inequality is just a relationship between two amounts, in which the amounts aren't the same.
Step-by-step explanation:
X = -6/29 is the correct answer
Answer: Letter Choice ( B): -x^2 - 4x + 7
Step-by-step explanation:
( 4x^2 - 7x + 9 ) - ( 5x^2 - 3x + 2 )
Remove Parentheses: (a) = a
4x^2 - 7x + 9 - ( 5x^2 - 3x + 2 )
- ( 5x^2 - 3x + 2 ): - 5x^2 + 3x - 2
Simplify:
4x^2 - 7x + 9 - 5x^2 + 3x - 2
Answer:
Letter Choice ( B ):
-X^2 - 4x + 7

Answer:
From September 20 to January 20, there are 4 months only which is equivalent to 1/3 of a year. The interest earned by the investment, P, made is calculated
Step-by-step explanation:
Answer:
a) E(x)=3.565
b) c=3.8475 --> P(X < 3.8475) = 0.75
c) The probability that X falls above or below 0.28 min from the mean is P=0.4954.
Step-by-step explanation:
We have the cumulative distribution function as information.
a) To calculate the expected value, we can calculate the value of x in which F(x) equals 0.5. This happens for x=3.565.
b) What is the value c such that P(X < c) = 0.75?
In this case, we have to calculate x to have F(x)=0.75
This happens for x=3.8475.
c) We have to calculate the probability that X falls above or below 0.28 min from the mean (x=3.565).
This is the probability that the time is between 3.285 and 3.845
We can calculate this as:
The probability that X falls above or below 0.28 min from the mean is P=0.4954.
