Answer:
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 scores 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 normal standard table or excel and we got:
Answer:
7 friends
Step-by-step explanation:
Given the inequality expression
17(g+2)+45.99<200
We are to find the value of g that satisfies the inequality
Expand
17g+34 +45.99<200
17g+79.99<200
Subtract 79.99 from both sides
17g+79.99-79.99<200-79.99
17g<120.01
g<120.01/17
g<7.059
Hence the max number of friend that can attend is 7friends.
