-6 -8=-14C. When you subtract from a negative number the product will be smaller than when you started. Sometimes it helps to draw a number line and count that way.

A sample of values has a mean of 500.0 and a standard deviation of 50.0. use the range rule of thumb to find estimates for the m

leonid [27]

The Range Rule of Thumb says that the range is about four times the standard deviation. (i.e. two standard deviations to the left and two standard deviations to the right of the mean).

Given that the mean is 500 and the standard deviation is 50, then

The minimum and the maximum "usual" values are given by

$500\pm2(50)=500\pm100 \\ \\ =(500-100,\ 500+100)=(400,\ 600)$

Therefore, the minimun "usual" value is 400 while the maximum "usual" value is 600.

A square field measuring 100.0 m by 100.0 m has an area of 1.00 hectare. an acre has an area of 43,600 ft2. if a lot has an area

liq [111]

The problem given above is simply a conversion problem. We are asked to convert from units of acres to units hectares. To do this, we need a conversion factor which would relate the different units involved. We either multiply or divide this certain value to the original measurement depending on what is asked. For this case, we use the given values to determine the relation. We do as follows:

1 hectare = 100 m x 100 m = 10000 m^2
1 hectare = 10000 m^2 ( 1 ft / 0.3048 m )^2 = 107639.10 ft^2
107639.10 ft^2 ( 1 acre / 43600 ft^2 ) = 2.47 acre

Thus, 1 hectare = 2.47 acres

12.0 acres ( 1 hectare / 2.47 acres ) = 4.86 hectares
