Answer:
The sample size required is 910.
Step-by-step explanation:
The confidence interval for population proportion is:

The margin of error is:

Given:

The critical value of <em>z</em> for 90% confidence level is:
*Use a standard normal table.
Compute the sample size required as follows:

Thus, the sample size required is 910.
8 is a cube: 2³
27 is a cube: 3³
The expression can be identified as "the sum of two cubes": (2z)³ + 3³.

(1200 mi)/(24 mi/h) × (1 day)/(24 h) = 25/12 day = 2 1/12 days
write the equation
Transfer 4.44 to other side and it's sign changes from positive to negative
After subtracting we will get result as 4.44
Arrange the equation as variable always comes at left side.
