7 is in the hundredths place.
There are 7 one hundredths.
Volume of Cylinder V₁ =πR². H
Volume of a cone V₂ = (1/3).πR².h
We know that H=4h (given) & R, the radius =75 &The total Volume = V₁+V₂,
We also know that the hopper has one cylinder & 2 equal cones
Hence
πR². H + 2 [(1/3).πR².h] =343,000 ft³
π(75)².H + 2[(1/3).π(75)².h] =343,000
But H = 4h, then
π(75)².4h + 2[(1/3).π(75)².h] =343,000. Solve for h
26250.π.h = 81,466.8.h = 343,000
& h=343,000/81,466.8, ==> h=4.16 ft & H =16.6 FT
μ = population mean
σ = 0.05, the population standard deviation
Sample size, n = 6
Sample mean,
= (1.05+1.04+1.01+1.06+0.94+0.99)/6 = 1.015
Because the sample size is less than 30, the confidence interval is
where
t* = 2.015, fromm the t-distribution with dof = 6-1 = 5.
The confidence interval for μ is
1.015 +/- 2.015(0.05/√6) = 1.015 +/- 0.0411 = (0.974, 1.056)
Answer: (0.974, 1.056) liters
Answer:
The area is:
Step-by-step explanation:
The area under the standard normal curve equals the z probability.
We look for the area of the region that is not shaded.
That is, we look:
Then we must find
Looking in the standard normal probability table we have to:
So:
I think its 9 but not really sure lol
