Answer:
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:
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 variable of interest 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:
Answer:
I think answer is 87<180 or maybe 87<12*15
Answer:
2 3/8
Step-by-step explanation:
You add 2 1/8 and 3 3/4 together= 5 7/8
Then subtract 5 7/8 from 8 1/4= 2 3/8

Answer:
120
Step-by-step explanation:
since 26 is the longest side, it would be the hypotenus and we can exclude it.
the equation for the area of a triangle is basexheight/2.
our base or height must be the other two sides
10x24=240
240/2=120
so 120 would be ur answer
