<span>It can be assumed that the sample mean would would be approximately normal by the mean distribution theorem. The mean distribution theorem states that a large enough sample size will have a distribution and mean approximately the same as the population mean. A sample of 250, half the size of 500, is of sufficient size to assume the distribution mean will be approximately normal like the population mean.</span>
Answer:
c = 12.73
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
c = 
c = 12.7279221
c = 12.73
Mark brainliest please!
[c] 70°
40+2x=180
2x=140
x=70
i use 2x since the angle measures of D and C are equivalent since it is an isosceles
Answer:
Your answer is 46 minutes.
Step-by-step explanation: By doing the median of the numbers you order the pairs from least to greatest. 38, 45, 47, 52. You find the middle number if its an even number of pairs you pick the two middle most numbers and add them together.
45 + 47= 92
Then you divide the sum by the number of pairs. Which we have 2 pairs.
92/2 = 46 hence your answer will be 46 minutes.
