Add the numbers of the ratio:
4 + 6 + 8 = 18
The ratio of the shortest side to the perimeter is 4:18.
The actual perimeter is 126.
4:18 = x:126
18x = 4 * 126
18x = 504
x = 28
Answer: The shortest side measures 28 ft.
The ratios are 5/2 adn 25/4 for the perimeter and area respectively
500+ 18(56) equals total cost of refrigerator
$1508

Answer:
54.80 MPa to 55.92 MPa
Step-by-step explanation:
Sample mean fracture strength (x) = 55.36 MPa
Sample standard deviation (s) = 3.99 MPa
Sample size (n) = 196.
The upper and lower bounds for a 95% confidence interval are given by:

The upper and lower bounds of the confidence interval are;

The 95% confidence interval for true average fracture strength is 54.80 MPa to 55.92 MPa
