Step-by-step explanation:
From the question we are told that
The sample size is
The the number that are parents x = 175
The proportion of parents is mathematically represented as
substituting values
The level of confidence is given as 99% which implies that the level of significance is
1%
The critical value for this level of significance is obtained from the table of critical value as
Generally the margin of error is mathematically evaluated as
substituting values
Generally the 99% confidence interval is mathematically represented as

A trapezoid is a quadrilateral with one pair of parallel sides. The formula for the area of a trapezoid is ↓
Area = (base 1 + base 2) h
The bases of the trapezoid are the parallel sides.
In the trapezoid shown, the bases are 22.2 cm and 8.52 cm and the height of the trapezoid is 9.86 cm. Now, we can plug these numbers into our formula.
(22.2 cm + 8.52 cm) (9.86 cm)
Next, the order of operations tells us that we need to simplify inside the parentheses first. 22.2 + 8.52 = 30.72 cm
(30.72 cm) (9.86 cm)
× 30.72 = 15.36
(15.36 cm) (9.86 cm) = 151.4496 cm²
