The answer is d because quotient means the outcome of a division between two numbers. So therefore it has to be a division equation, which is d.
Answer:
Step-by-step explanation: You need to find a the lowest number that the denominators can be timed by. In you're case. You can just times 5 by 2 = 10
So that both the denominators are 10. And the denominator that was once 5. The numerator of that fraction also needs to be timed by 2.
So then you have 7 18/10 - 6 15/10
Then you can convert them to to proper fractions 8 8/10 - 7 5/10
Then you can take away the fractions so it's
8 8/10 - 7 5/10 = 1 3/10
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
