Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
This means that the volume of a cone is 1/3 × volume of a cylinder if they have the same base and height.
If the cylinder can hold about 4,712 Centimeters cubed of sand and Jared says that the cone can hold about 1,178 Centimeters cubed of sand, then
Jared is not correct because the cone and the cylinder have the same base and height so the cone holds StartFraction 4,712 Over 3 EndFraction almost-equals 1,571 centimeters cubed of sand.
Answer:
The repair/reboot time needs to be reduced by 600 hours so as to increase availability time by 5%.
Step-by-step explanation:
To increase availability by 5%, the amount of hours of availability is multiplied 105%.
therefore 1.05 × 12000 = 12600 hours
Therefore the repair/reboot time needs to be reduced by 600 hours.
If the backpack (b) contains only textbooks (t) and notebooks (n), the total weight of the backpack is:
b+t+n
but notebooks are 4 pounds, so actually:
b+t+4
also, the backpack weights 2 pounds, so the total weight is:
2+t+4 =t+6
now, "Seventy percent of
<span>
the total weight is textbooks. ", this means that
t=70%(t+6) - this equation can be used to determine the weight of the textbooks!

Yes his equations are correct
First of all, this is not an observational study, but an experiment, since we have two groups and one of the two groups is manipulated or treated. In an observational study the subjects are only observed.
Second, the students did not choose their groups - so we can't choose the last answer.
Therefore the correct answer is:
This is an experiment because a treatment was applied to a group.
