Bryan has enough to buy skateboard as it will cost $44.94
Step-by-step explanation:
Original price = $70.00
Discount = 40%
Amount of discount = 40% of original price
Amount of discount =
Amount of discount =
Amount of discount = $28
Price after discount = Original price - amount of discount
Sales tax = 7% =
Sales tax amount = Price after discount (0.07)
Price of skateboard = Price after discount + sales tax
Price of skateboard = 42+2.94 = $44.94

The sample proportion, p-hat, of engineers who have master's degrees is 68.5% out of 200 engineers.
p-hat proportion:
In this proportion, "p" denotes the probability of a certain event occurring or a certain parameter being true for a certain population, but when a population is large, it may be impractical or impossible to measure it directly. So, we have used the proportion for that cases.
The general form for calculating p-hat proportion is,
where
x is the number of successes in the sample, and
y is the size of the sample.
Given,
In a random sample of 200 engineers, 137 have a master's degree.
Here we need to find the the sample proportion, p-hat, of engineers who have master's degrees
According to the question,
x = 137 (number of successes in the sample)
and y = 200 (size of the sample)
Now apply the value on the formula then we get,
So, the value of p-hat is
The results are usually reported as a percentage, which in this case would be
=> 0.685 x 100 = 68.5%
Therefore, the sample proportion, p-hat, of engineers who have master's degrees is 68.5% out of 200 engineers.
