To find the mean of a set of numbers you simply add all the numbers then divide by how many numbers you added
113+185+140+219+295 = 952
952/5 = 190.4 (if you need it rounded, just put 190)
The answer is D hope this helps!!
I wasn't sure about the equation for question two, but here's my best shot at it.
Answer: 4 / 5
Reasoning:
1) The function sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) From the figure:
x = A
opposite-leg = 20
hypotenuse = 25
3) Calculations:
sin(A) = 20 / 25 = 4 / 5
Answer: 4 / 5
I'll teach and give you the answer for you problem (5 2/7 −1 1/2 )∙(1− 14/53 )
Convert mixed numbers to improper fractions 5 2/7 = 37/7:
(37/7-1 1/2) * (1- 14/53
Convert mixed numbers to improper fractions 1 1/2 = 3/2:
(37/7-3/2) * (1- 14/53
Join 37/7-3/2 = 53/14
53/14(-14/53+1)
Join 1-14/53 = 39/53
53/14 * 39/53
Cross-Cancel 53:
39/14
Your Answer As A Improper Fraction---> 39/14
Your Answer As A Mixed Number---> 2 11/14
plz mark me as brainliest :)
