Answer:

D.

Step-by-step explanation:

A is incorrect because the range of the data is basically just subtraction. The range of 20-40 year old men's heart rates are higher than 50-70 year old men. B is incorrect. Think of "median" as "middle". The heart rates of the 20-40 year old men is higher than the heart rates of the 50-70 year old men. C is incorrect, because the minimum heart rate is the "starting point" of the box plot, in these cases for the 20-40 year old men, that would be 75, which is higher than the 50-70 year old men.

F(x)=x^2+10x-12

Answer:

Therefore the two values required are 2.08 and -11.08.

Step-by-step explanation:

i) f(x) = x^{2} +  10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.

ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.

This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.

∴ x^{2} + 10x -12 = 0    ⇒    x  = (-10 ± \sqrt{10^{2} +(48)} ) ÷ 2                                                          

                                          = (-10 ± 12.166)÷2        =   2.08, -11.08

Therefore the two values required are 2.08 and -11.08

love history [14]

hopefully this helps you and gives you insight in how to solve the problems from now on (:

= $11.8 + (2012-1997)([$11.8-$7.4][1997-1990])

= $11.8 + 5 ($4.4/7)

= $11.8 4/5 + $22/7

= $59/5 + $22/7

= $413/35 + $110/35

= $523/35 or $14 33/35

answer : SALES IN 2012 WOULD BE $14 33/35 BILLION OR $14.9 3/7
