Answer:
The correct option is B. 16.3
Step-by-step explanation:
We are given a vector with components
V = 36x +33y
To solve this problem, we find its magnitude
|V| = SQRT (36^2 + 33^2)
|V| = SQRT (2385)
|V| = 48.836
To find the magnitude of the new vector we divide by three the previous quantity
|V2| = 48.836/3 = 16.278

Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :
3.1433174885
= 3.14
