We know that 1 serving = 4 bananas
3 apples
6 pears
and 20 strawberrys
To get 30 we need to half 20 =10 20+10=30
That means we also needs to half the other ones
1/2 of 4 = 2 4+2=6
1/2 of 3 = 1.5 3+ 1.5=4.5
1/2 of 6 = 3 6+3=9
6 Bananas
4.5 Apples
9 Pears
30 strawberries diced.
The exponential distribution is:

where

The probability we want is how likely will a dvd player last more than 8 years, given it has already lasted 5 years
To find this, you use conditional probability.

where A is P(x>8) and B is P(x>5)
To find these probabilities, integrate over the distribution:

Sub into conditional probability formula:

Final Answer: Given a dvd player is more than 5 years old, the probability that it will last another 3 more years is about 54.9%

Answer:
Step-by-step explanation:
we have
-------> 
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
Remember that

Well when you go lower with negatives the number gets bigger so
It was -4C then it was 2 lower which is -6C then it got lower again in the evening by 1 degree celcius which gives the answer -7 degrees celcius
