Step-by-step explanation:
The 95% prediction interval for trouble shooting time with 8 hours of training was determined to be 12.822 to 19.261.
This means that we can be 95% sure that the true mean of the interval for trouble shooting time with 8 hours of training is between 12.822 and 19.261.
Answer:
Step-by-step explanation:
Use FOIL method
(x + 6)(x +6) = x*x + x*6 +6*x + 6*6
= x² +<u> 6x + 6x</u> + 36 {add like terms}
= x² + 12x + 36

Answer:
The Width of each side of the bookmark in centimeters = 5cm
Step-by-step explanation:
A bookmark shaped like a rectangle has a total perimeter of38cm the length of the one of its sides is 14 what is the width of each side of the bookmark in centimeters
The formula for perimeter fo a rectangle =
P = 2L + 2W
Where L = Length
W = Width
Hence: From the above question:
38cm = 2 × 14 cm + 2 W
38cm = 28cm + 2W
2W = 38cm - 28cm
2W = 10cm
W = 10cm/2
W = 5cm
Hence, the Width of the rectangle(each side of the bookmark in centimeters) = 5cm
