Why do fractions need to have a common denominator before you add or subtract them?

Fractions need common denominator to add or subtract them because without denominators a fraction is not a fraction, it is a whole number
Example - 2/8 is a fraction
                but 2 is not a fraction

Is Statistics mathematics or science? Defend your answer.
ohaa [14]

Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.

• It is mostly used to find the census, which is maths.

• It is used to find interest rates and other banking terms using statistics, which is again related to math.

• It is also used to find the average people living in a village or panchayat, which is also math.

Therefore I strongly believe that Statistics is Maths.

Thank You!

The increase in a person’s body temperature T(t), above 98.6ºF, can be modeled by the function T(t)=4t/t^2+1, where trepresents

The meaning of the horizontal asymptote is that the increase in a person's body temperature is a constant value when long time passes.

You can obtain that value by calculating the limit of the function when t → ∞:

                 4t
T(t) =  ------------- => Lim T(t) when t → +∞ = 0.
             t^2 + 1

That means that at long term the Temperature tends to remain at 98.6°F.

irinina [24]
  • (-6,1)
  • (-2,5)

Slope:-

\\ \sf\longmapsto m=\dfrac{5-1}{-2+6}=\dfrac{4}{4}=1

Point-Slope form

\\ \sf\longmapsto y-y_1=m(x-x_1)

\\ \sf\longmapsto y-1=1(x+6)

\\ \sf\longmapsto y-1=x+6

\\ \sf\longmapsto x-y+7=0
