Answer:
We are 95% confident that the average weight of the heaviest egg that is still medium size is 3.52 oz
Step-by-step explanation:
Mean = 3.2 oz, sd = 0.13 oz
Assuming there are 3 heavy eggs, n= 3, degree of freedom = n-1 = 3-1 = 2, t-value corresponding to 2 degrees of freedom and 95% confidence level is 4.303
Error margin = t×sd/√n = 4.303×0.13/√3 = 0.32 oz
Upper limit (heaviest egg that is still medium size) = mean + error margin = 3.2 + 0.32 = 3.52 oz
Answer: 3 hours
Step-by-step explanation:
If you add up 25+15=40 if you add up 40+15=55, 55+15=70, 70+15=85
Answer:
175 m
Step-by-step explanation:
We are given;
- The perimeter of a rectangle as 25 m
We are required to determine the new perimeter if the sides of the rectangle are multiplied by 7.
We know that;
Perimeter of a rectangle = 2(L+W)
Therefore, initially;
2(L+W) = 25 m
Hence;
L + W = 12.5 m
if the sides are multiplied by 7, then;
New length = 7L
New Width = 7W
Thus;
New perimeter = 2(7L+7W)
= 14 (L + W)
but, L + W = 12.5
Thus;
New perimeter = 14 (12.5)
= 175 m
Therefore, the new perimeter will be 175 m
