1.42 because you subtract 10 from the price
Given:difference in the mean weight gain is 0.60 gramsstandard deviation of the difference in sample mean is 0.305
68% confidence interval for the population mean difference is a) 0.305
0.60 + 1 * 0.3050.60 + 0.305 = 0.9050.60 - 0.305 = 0.295
95% confidence interval for the population mean difference is c) 0.61
0.60 + 2 * 0.3050.60 + 0.61 = 1.210.60 - 0.61 = -0.01
Answer:
side measure = 9 in
Step-by-step explanation:
volume of a cube: 
where V is the volume and s is one side of the cube
Given volume = 729 in³
![\implies s=\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Cimplies%20s%3D%5Csqrt%5B3%5D%7B729%7D)
Area of a triangle: 1/2 base x height
81 ft^2 = 1/2 (18 feet) (height)
Solve for x
81 / (1/2 x 18) = 9 feet for height
