Answer:
V = 11.4 cubic yards
Step-by-step explanation:
1 foot = 12 inches
1 yard = 36 inches
1 cubic yard = 46656 cubic inches
change the given values to inches by multiplying by 12
Length = 10'8" , round to higher foot
Length = 11*12 =
Length = 132 inches
Width = 6'4", round to higher foot
Width = 7*12
Width = 84 inches
Depth = 4'
Depth = 4*12 = 48 inches
The volume V = length x width x depth = 132 x 84 x 48 = 532224 cubic inches
divide by 46656 get cubic yards
V = 11.4 cubic yards

Answer:
a. There's a 95% chance that the true proportion is in the confidence interval.
Step-by-step explanation:
When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.
Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.
When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.
The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
Solution:
Two trains are moving in opposite direction with Speed 40 kmph and 60 kmph. Make train B stationary and then take the Speed of train A relative to the train B. So relative Speed of train A = 40 + 60 = 100 kmph. Before it crashes into the stationary train B it has to travel a Distance of 200 m which it will do in (0.2/100 ) hours. During this duration, the average Speed of bird has been 10 kmph i.e. before the crash total Distance covered by the bird = 0.2 * 10/100 km = 20 meters.
Hope it helps
What’s the question lol they’re all filled in correctly
