Answer:
a) 
b) 
c) 
d) 
And we can find this probability with this formula from the Bayes theorem:
Step-by-step explanation:
For this case we assume that the random variable X follows this distribution:
Part a
The probability density function is given by the following expression:
Part b
We want this probability:
And we can use the cumulative distribution function given by:
And replacing we got:
Part c
We want this probability:
And we can use the CDF again and we have:
Part d
We want this conditional probabilty:
And we can find this probability with this formula from the Bayes theorem:
As a fraction it’s 48 7/10
As a percentage it’s 4870%

For this problem you'll get a number, find it's opposite and sum 96 to it. The equation used will be:
x = -x + 96
Where:
x = a number
-x = the opposite of x
So:
x = -x + 96
x + x = 96
2x = 96
x = 96 / 2
x = 48
And now, if you do the sum to prove your answer:
48 - 96 = -48

Answer:
y = x^2 +6x+8
Step-by-step explanation:
First find the zeros, -4 ,-2
y =a (x - -4) (x - -2)
y = a(x+4)(x+2)
Then it is multiplied by a constant so pick a point on the curve and solve for the constant
We will use (0,8)
8 = a(0+4)(0+2)
8 = a(8)
a =1
y = (x+4)(x+2)
Writing in standard form
FOIL
y = x^2 +2x+4x+8
y = x^2 +6x+8
Answer:
The first option
Step-by-step explanation:
Since all sides are obtuse, its an obtuse triangle.
