Answer:
38.42cm
Step-by-step explanation:
Given that the length of the sides of a rectangle are 30 cm and 24 cm.
The length of the diagonal can be obtiaed using Pythagoras rule
Length of the diagonal = hypotenus
Hypotenus = sqrt(opposite ² + adjacent ²)
Opposite and adjacent sides are 30cm and 24 cm
Hypotenus = sqrt(30² + 24²)
Hypotenus = sqrt(900 + 576)
Hypotenus = sqrt(1476)
Hypotenus = 38.419
Length of diagonal = 38.42cm

Answer:
64
Step-by-step explanation:
Given that an advisor to the mayor of a large city wants to estimate, within 3 minutes, the mean travel time to work for all employees who work within the city limits.
Let X be the random variable denoting the time for employees to travel within city limit
Std dev of X
For 95% confidence interval Z critical 1.96 is used because population std dev is known
Margin of error
i.e.
where n is the desired sample size.
Simplify to get
Hence atleast 64 employees should he poll
