An experiment reported in Popular Science compared fuel economies for two types of similarly equipped diesel mini trucks. Let us

suppose that 11 Volkswagen and 9 Toyota trucks were tested in 90- kilometers per-hour steady-paced trials. If the 11 Volkswagen trucks averaged 16 kilometers per liter with a standard deviation of 1.0 kilometer per liter and the 9 Toyota trucks averaged 11 kilometers per liter with a standard deviation of 0.8 kilometer per liter. Assume that the distances per liter for the truck models are approximately normally distributed with equal variances. Construct a 98% confidence interval for ????????1/????????2, where ????????1 and ????????2 are, respectively, the standard deviations for the distances traveled per liter of fuel by the Volkswagen and Toyota mini trucks.

weqwewe [10]

Answer: -15 meters


Step-by-step explanation:

Given: The Tunnel of Fear ride climbs straight up to its peak above the ground = 50 meters or +50 meters

Then, it drops into an underground tunnel  = 65 meters or -65 meters

Thus, the elevation of the tunnel relative to the ground= +50-65=-15 meters

Hence, the elevation of the tunnel relative to the ground= -15 meters.

Find the volume of the following figure round your answer to the nearest tenth and if necessary use pi
GREYUIT [131]

Answer:

1526.04

Step-by-step explanation:

the formula for calculating the volume of cone is

V=πr^2(h/3)

Thus,

V = (3.14)(9)^2(18/3)

V = (3.14)(81)(6)

V = 1536.04 yd^3

Rounding off to the nearest tenth, we get

V = 1536 yd^3
