Explanation: I’ve taken this test before and got it right :)
Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.
400-126=274

0-6 can't go into so make the 0 a 6
Then make 0-2 make 0 a 10 then a 9
Then make 4 into a 3
Step-by-step explanation:
Let ABC be a right angled triangle where there's a right angle in B . Let the measure of the angle BAC be ∅. So,
Also,
Now adding the values of sin^2∅& cos^2∅,
But we know that
by applying Pythagorean Theorem
So ,
