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:
Divide the number of contestants by 4 and when there is 120 contestants there is 30 winners
Step-by-step explanation:
Looking back at past sequences we can see that when we had 8 contestants we had 2 winners 8/4=2 and we also saw 16/4=4 so that was the formula now we just had to do it on 120 contestants and now we get 30 winners....Hope this helps! :)

Answer:
x= 11, -15
Step-by-step explanation:
(4x + 5) + x^2 +1 0) = 180
x^2 + 4x + 15 = 180
x^2 + 4x + 15 - 180 = 0
x^2 + 4x - 165 = 0
x = 11, -15
