Answer: The probability that a randomly selected tire will have a tread-life of less than 65,000 miles is 0.7872 .
Step-by-step explanation:
The cumulative distribution function for exponential distribution is :-
, where
is the mean of the distribution.
As per given , we have
Average tread-life of a certain brand of tire : 
Now , the probability that a randomly selected tire will have a tread-life of less than 65,000 miles will be :

Hence , the probability that a randomly selected tire will have a tread-life of less than 65,000 miles is 0.7872 .
Answer:
t=$2.20c
Step-by-step explanation:
4 pieces of chicken for $8.80
Cost of 4 pieces of chicken=$8.80
$8.80/4=$2.20 for each chicken
t=$2.20c
If you divide 27 by 75 you will get .36 calories. .36 is how many calories are in one gram of corn flakes. So if you multiply .36 and 120 you will get 43.2 therefore there is 43.2 calories in 120 grams of corn flakes.
Given: £90 is divided among Aahil, James and Merav in the ratio 1:3:5.
To find: How much Merav gets.
Answer:
Let's assume the shares of each to be 'x'.
This implies that 1x + 3x + 5x = 90.
9x = 90
x = 90/9
x = 10
Substituting this value of x in the ratio,
- 1 × 10 = 10 [<em>Aahil's share</em>]
- 3 × 10 = 30 [<em>James' share</em>]
- 5 × 10 = 50 [<em>Merav's share</em>]
Therefore, Merav gets £50.
Hope it helps. :)
Answer:
-2. Not really sure on this one because there is only one equation, so I think it is impossible.
Step-by-step explanation:
x=4-y
x+y-6
4-6=-2
