Answer:
He should spend 3 minutes or less on each scale
Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal
Step-by-step explanation:
Let
t ------> is the number of minutes he spends on each scale
Remember that the phrase "at least" is equal to "greater than or equal"
so
The inequality that represent this scenario is

solve for t


Multiply by -1 both sides

Divide by 5 both sides

Sven is incorrect
He should spend 3 minutes or less on each scale
Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal
Answer:
Event A = { Chevrolet , Buick }
Event B = { Ford , Lincoln }
Event C = { Toyota }
Step-by-step explanation:
- Mutually exclusive events are such that their probability of coming true simultaneously is zero. If we consider set notations we could say.
P (A & B) = P (B & C) = P (A & C) = 0
- In our case these events A,B, and C can be defined as:
Answer:
Event A = { Chevrolet , Buick }
Event B = { Ford , Lincoln }
Event C = { Toyota }
Answer: 0.129
Step-by-step explanation:
Let
denotes a random variable that represents the mean weight of babies born.
Population mean : 
Standard deviation: 
Sample size = 83
Now, the probability that the mean weight of the sample babies would differ from the population mean by greater than 54 grams will be :

hence, the required probability = 0.129
Via the generating function method, let

Then take the recurrence,

multiply everything by

and sum over all

:

Re-index the sums or add/remove terms as needed in order to be able to express them in terms of

:



So the recurrence relation is transformed to



For appropriate values of

, we can express the RHS in terms of geometric power series:

which tells us that
<span>Given
situation:
=> A deadler paid $10 000 for a boat at an auction.
=> At the dealership, a sales person sold the boat for 30% more than the
auction price
=> 10 000 dollars + 30%
=> Then the salesperson received a commission of 25% of the difference
between the auction price and the dealership price
=> 10 000 + 25%
Let’s find the solution
=> 10 000 x .30 = 3000
=> 10 000 + 3 000 = 13 000, he sell it for this price
=> then he received a commission
=> 13 000 – 3 000 = 10 000
=> 10 000 x .25
=> 2500 , his commission </span>
