15 ÷ .30 = 50
Answer:
125/2 or 62.5 or 62 1/2 (x=)
Step-by-step explanation:
25/4=x/10 multiply everything by 20
25*20/4=20x/10 simplify
25*5=2x simplify
125=2x divide on both sides
125/2 or 62.5 or 62 1/2=x
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
water drinking habits:
mean = 62 ounces
standard deviation = 5.2 ounces
Step 02:
normally distribution:
95% ===> 2 SD
(62 + 5.2 + 5.2) ounces = 72.4 ounces ==> + 2 SD
(62 - 5.2 - 5.2) ounces = 51.6 ounces ==> - 2 SD
The answer is:
51.6 ounces - 72.4 ounces
