Since 68% of the sample ranges from the plus minus first standard deviation from the mean, then interval wherein it will occur will be between 53.5% to 60.5%. I got this answer through adding and subtracting one standard deviation (3.5) from the mean (which is 57).
4^4 * 4^3

4^5
= 4^7 / 4^5
= 4^(7-5)
= 4^2 = 16 Answer
Answer:
a. 60/61
Step-by-step explanation:
With reference angle A
base(b) = 60
hypotenuse (h) = 61
Now
Cos(A) = b / h
= 60/ 61
Q+P =180 so (Q is 137) p=s so (s is 43) and q = r so (r is 137)
