So..Volume of a cylinder = pi(r)^2 x Height
The first can has a radius of 1.75 (3.5/2) and a height of 1.25 inches..put that in the formula and you'll get the volume of the first cylinder ~ 12.02
Do the same thing with the second cylinder and you'll get ~5.65 as the volume.
Now calculate the difference between the two by simply subtracting the two volumes and the difference would approximately be 6.37
hope this helps! :)
Answer:
the vertex is (-7,-90)
the focus is ( -7, -359/4)= (-7,-89.75)
semi-axis length; 1/4=0.25
focal parameter: 1/2=0.5
eccentricity;1
directrix: y=-361/4

Answer:
B
Step-by-step explanation:
The recommended sample size n for point estimates is:
n = NX / (N + X - 1)
where N is the population size, and X is defined as:
X = Z² p (1 - p) / E²
where Z is the critical value, p is the sample proportion, and E is the margin of error.
Assume a confidence level of level of 95% and a margin of error of 5%.
α = 0.05, Z(α/2) = 1.96
E = 0.05
Of the 40 units tested, 2 had lifespans less than 26 days. So the proportion is:
p = 2/40 = 0.05
Therefore:
X = (1.96)² (0.05) (1 - 0.05) / (0.05)²
X = 73
Given N = 2000:
n = (2000) (73) / (2000 + 73 - 1)
n = 70.45
Rounding, the recommended sample size is 70.
Answer:
2,500
Step-by-step explanation:
Multiply 10,000 with 1/4 and since 1/4 equals to 25%.
10,000 x 1/4 = 2,500
Your answer is there and I hope this helps!
