Where does that 682 come from? It cannot be the surface area of a cube with a side of 50 inches.
The edge length is 50 inches, so s = 50
SA = 6 * 50^2
SA = 15000 in^2
Answer: So at the very minimum, you need <u>15000</u> square inches of wrapping paper.
First we have to find the mean (average)
mean = (564 + 1000 + 848 + 1495 + 1348) / 5 = 5255 / 5 = 1051
now we subtract the mean from every data point, then square it
564 - 1051 = -487......-487^2 = 237169
1000 - 1051 = -51......-51^2 = 2601
848 - 1051 = -203......-203^2 = 41209
1495 - 1051 = 444......444^2 = 197136
1348 - 1051 = 297......297^2 = 88209
now find the mean of the results.....but know when ur dealing with a sample instead of the whole population, u divide by 1 number less...so instead of dividing by 5, u divide by 4.
(237169 + 2601 + 41209 + 197136 + 88209) / 4 = 566324 / 4 =
141581.....this is called ur variance
now take the square root of the variance and u have ur standard deviation
sqrt (141581) = 376.272 rounds to 376.27 <==
Use a calculator. Add then do the exponent.
Answer:
x = 52
Step-by-step explanation:
These angles are vertical angles meaning they are equal to each other.
4x - 101 = 2x + 3
2x - 101 = 3
2x = 104
x = 52
Answer:
1.75

you have to make it an improper fraction first then subtract:)
