Answer: $13
Step-by-step explanation:
To determine the solution arithmetically in two steps, first divide 68.25 by 3 and then subtract 9.75 from the result. To determine the solution algebraically, set up and solve the equation 3(x+9.75)=68.25. Each friend paid $13 for dinner.
If score of 3,540 points is 2 standard deviations above the mean score of 3,110, then:
3,110 + 2 s= 3,540
2 s = 3,540 - 3,110 = 430
s = 430 : 2
s = 215
Answer: A) The standard deviation is 215.
Answer:
Step-by-step explanation:
7 lenthii=38 inches, 10 lenthii=410
410-225.3=184.7
184.7+38=222.7 222.7+38=260.7
260.7- 4 lenthii=225.3
