133.5
Step-by-step explanation:
Area of paralleogram is base x height. The base is 15 as given. We need to find the height.
Using triangle MNJ we can find it.
We need to find side MN but we are given an angle adjacent to that side 90. We also given another angle and a side adjacent to that angle 52 and 7 respectively.
We can use law of sines to find MN
sin of 90 =1 so multiply 1 by both sides
simplify that and we get mn=8.9.
So know we can multiply 8.9 by 1t to find the area.
15×8.9=
133.5
Answer:
The approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 177.6 and 316.2 is 68%.
The approximate percentage of women with platelet counts between 39.0 and 454.8 is 99.7%
Step-by-step explanation:
Mean :
Standard deviation :
Empirical rule :
1 ) 68% of the data lies within 1 standard deviation of mean
This means 68% of data lies between: to
2) 95% of the data lies within 2 standard deviation of mean
This means 95% of data lies between: to
3) 99.7% of the data lies within 3 standard deviation of mean
This means 99.7% of data lies between: to
Now to find the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 177.6 and 316. 2
Use rule 1: to
to
to
So, according to rule 1, 68% of the data lies within 1 standard deviation of mean i.e. 68% of the data lies between 177.6 and 316.2.
Now to find the approximate percentage of women with platelet counts between 39.0 and 454.8?
Use rule 3: to
to
to
So, According to rule 3 : 99.7% of the data lies within 3 standard deviation of mean i.e. 99.7% of data lies between 39.0 and 454.8
