Answer:
c. 61.25 kg
Step-by-step explanation:
The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean.
a. 15.31 kg
b. 51.40 kg
c. 61.25 kg
d. 80.49 kg
Margin of Error Formula= z × Standard deviation/√n
95% confidence interval = 1.96
Standard deviation = 125kg
n = 16 samples
Margin of error= 1.96 × 125/√16
= 1.96 × 125/4
= 245/4
= 61.25kg
The margin of error in estimating the true mean weight of male baluga whales in the Artic Ocean is 61.25kg
35 . because 5 times 7 equal 35 so 35 divide by 7 equal 35
Dimension of smaller garden :
l = 1/2 ft.
b = 2/3 ft.
Dimension of bigger garden :
L = 4 ft.
Let , breadth be x ft.
We know , area is given by :
Area = L×B.
Area of small garden = 
Area of big garden 
Hence, this is the required solution.
