Martin is interested in the new hypermiling movement which focuses on getting the best miles per gallon (mpg) when driving. he gathered some data about the weights, in thousands of pounds, of different cars and their average mpg. the graph below shows the results of martin's research.

select the true statement based on the graph.

a.
the situation shows correlation without causation.
b.
the situation shows neither correlation nor causation.
c.
there is not enough information.
d.
the situation shows correlation with causation.

the answer is d. (1.2, -4.7) on edgn

hope this !

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
