The mean makes sense only if the 1-5 scale is an interval scale. This requires that, for example, the difference between 1 and 2 on the scale is the same as the difference between 3 and 4.

Assuming that is the case, suppose you have a% at 1, b% at 2 and so on.

then a + b + c + d + e = 100

The mean is

(1*a + 2*b + 3*c + 4*d + 5*e)/100

1 yard =36 inches so ,36/15 =2.4 2.4 is the scale factor if the scale is 15 inches equals 1yard

Well, honey, first things first, let's get our units in order. Convert 5 feet to yards (which is 1.67 yards) and add that to the 15 yards. So, we have a total of 16.67 yards. To find the scale factor, divide the total distance by the original distance, which gives us 3.33. So, the scale factor for 5 feet and 15 yards is 3.33.

To divide by a percentage, multiply the dividend by 100 and divide by the percentage value. For example,37 / 15% = 37 * 100 / 15

I guess you are talking about showing percentages on a pie chart so that the whole chart shows 100 %. The full turn is 360o represents 100 % ⇒ 360o ÷ 100 = 3.6o represents 100 % ÷ 100 = 1 % ⇒ multiply 3.6o by the percentage to get the required angle. eg 15% is 1% x 15 ⇒ angle is 3.6o x 15 = 54o.

There are different percentages of NPK fertilizers: For example some of them are 20-20-20 which means 20% Nitrogen 20% phosphorous and 20% Potas There are other percentages also for example 15-15-15 or 10-20-10 or ... Base on the plants need different percentages are being used.

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature. So, -15 degrees Celsius would be 258.15 Kelvin (-15 + 273.15).

The answer is 258.15 K (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K, add 273.15 to C.

Ten, 15 and 20 percent appear as percentages of nitrogen in houseplant fertilizers. Clemson University extension publications suggest such balanced percentages of nitrogen, phosphorus and potassium (NPK) fertilizers as 10-10-10 and 20-20-20 for houseplants grown for their foliage. They tend toward 15-30-15 NPK percentages for houseplants grown for their flowers.

I do not think anybody says it like that. A thousand million would be 10^9 or a Billion (short scale) and a Milliard (long scale). So depending on where you live, it would be equivalent to 15 Billion, or 15 Milliard, or you could convert to scientific notation: 15 x 10^9 would become 1.5 x 10^10.

The answer is 258.15 K (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K, add 273.15 to C.
