Step-by-step explanation:
The 95% is confidence interval its not a probability estimate. The probability will be different from the confidence interval. Confidence interval is about the population mean and is not calculated based on sample mean. Every confidence interval contains the sample mean. There is 95% confidence that the number of televisions per American household is between 1.15 to 4.20.
Answer:
150.8
Step-by-step explanation:
Volume of big cylinder = pi * r^2 * h
small cylinder has a radius half the lenght of big cylinder, so height is also half of the big cylinder, since they are similar
so volume of small cylinder= pi * (r/2)^2 * h/2 = (pi * r^2 *h)/8= 1206/8= 150.75
The picture in the attached figure
we know that
m∠BXA =
°
'
m∠CXB =
°
'
m∠CXA = ?
m∠CXA = m∠BXA + m∠CXB
m∠CXA =
°
' +
°

m∠CXA =

'
therefore
the answer ism∠CXA = ° '
Divide bags of sand by gallons of water:
14 /6 = 2.33
21/9 = 2.33
The ratio is the same, so this means for every gallon of water you need 2.33 bags of sand.
Convert the fractions into decimals and you will get 7/3 = 2.33
The answer for Part 1 is D) 7/3
For part 2, multiply the gallons of water by 2.33 to get the number of sand bags needed:
12 x 2.33 = 27.99, which rounds to 28.
The answer is C) 28 bags.
