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:
7
Step-by-step explanation:
625 - 576 = 49
square root of 49 = 7
Your answer is 6
Explanation so
L=15
W=4
D=2
15x4=60
60x2=120
Then you use 120divide it by 20 (per hour) and your answer is 6hours
Answer
Step-by-step explanation:
If 25 goes into 100 four times, then multiple 9 x 4 and then make it into a precent. 9 x 4 = 36, would equal .36
Answer:
a =8
Step-by-step explanation:
-5(a + 3) = -55
Distribute
-5a -15 = -55
Add 15 to each side
-5a-15+15 = -55+15
-5a = -40
Divide each side by -5
-5a/-5 = -40/-5
a = 8
