Answer:
15.60
Step-by-step explanation:
The sub total before tax is 34.95. You know the socks cost 3.75 and the skirt and shoes are the same or equal price. This means after subtracting the cost of the socks, you spent 34.95 - 3.75 = 31.20. Since the skirt and shoes cost the same, divide 31.20 by 2. This is $15.60.
For question 1, you need to look at the number and decide on the closest square numbers.
For this example, the two closest square numbers to 160 are 144 (12²) and 169 (13²).
Therefore, we can say that the square root of 160 must be between 12 and 13.
For question 2, when we find the area of a 4-sided shape, we have to multiply the 2 adjacent sides. In this case, as the shape is a square when we multiply the 2 sides it is this same as squaring 1 side. This means that when we find the side from an area of a square you take the square root.
We found in question 1 that 13² is 169, therefore the square root is 13 and the sides must each be 13 ft long.
Answer:
The sample proportion 
is within 0.03 of the true proportion of customers who are under age 21 is 0.803
Step-by-step explanation:
Total no. of customers = n = 400
We are given that the true population proportion of customers under age 21 is 0.68.
So, p =0.68
q=1-p=1-0.68=0.32
Standard deviation =
We are supposed to find the probability that the sample proportion is within 0.03 of the true proportion of customers who are under age 21 that is , what is the probability that is between 0.68 - 0.03 and 0.68+ 0.03
Using Z table
Hence the sample proportion is within 0.03 of the true proportion of customers who are under age 21 is 0.803
