Answer:

Step-by-step explanation:
From the question we are told that:
Population mean 
Population standard deviation 
Sample size 
Generally the equation for Standard error is mathematically given by



Based on the angles, we know this is a 45-45-90 triangle.
In this type of triangle, x and y will be equal. The formula for the sides is x * rad 2 = 8 .
8/ rad 2 = 5.66
Both X and Y are 5.66 units.
Answer:
Table 1 = Proportional
y is 7 times x
Table 2 = Not proportional

Answer:
1 and 3/4 days are equal to 42 hours
Step-by-step explanation:
42 hours = (42 hours) (1 day / 24 hours)
42 hours = 42/24 days
Simplyfing the fraction: Dividing the numerator and denominator by 6:
42 hours = (42/6) / (24/6) days
42 hours = 7/4 days
42 hours = (4+3)/4 days
42 hours = (4/4+3/4) days
42 hours = 1 3/4 days
