The surface casing of the well is to be cemented to the surface with a single-stage cementing using Class G cement + 5% bentonite. Estimate the total number of sacks required for cement & bentonite and total time required to seal surface casing with 20% excess of the total volume of slurry.
Additional information: The shoe track is 60 ft and has a rathole of 10ft. 15 minutes required to release the plugs with 15 sacks/min of mixing rate and 250 gal/min of pumping rate.

The brain volumes (cm3) of 20 brains have a mean of 1052.9 cm3 and a standard deviation of 121.3 cm3. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1245.5 cm3 be significantly high?

Statement: I personally believe that our social security tax is one of the most important taxes to be paid. I think its important to pay this tax because, by paying it because of the benefits it offers later in life. Spouses and children of the deceased are given their paid tax money to help them after their loved one can no longer contribute. Our elderly get monthly retirement money because they paid their tax. Disabled workers and their dependents get money because they paid their social security tax. To conclude by paying social security tax it means that later in life if ever need be money is able to be given to the ones who need it in hard times, especially our elderly who have retired.
