Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43,
1 answer:
Answer:
Raymond was for 29 minutes on the trampoline.
Step-by-step explanation:
We are given the following in the question:
Total cost of session = $43.25
Entrance fee = $7
Cost per minute = $1.25
Let t be the minutes that Raymond was on the trampoline.
Thus, we can write
Total cost =
Entrance fee + cost per mute(minutes that Raymond was on trampoline)
Putting the values, we get,
Thus, Raymond was for 29 minutes on the trampoline.

Answer:
And we can find this probability using the complement rule and with excel or the normal standard table:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with excel or the normal standard table:
