Speed = distance / time
7 = 17.5 / t
t = 17.5 / 7
= 2.5 minutes
If the temperature in frostburg is 18 less than the temperature in coldspot, then the following equation compares the two temperatures:

where
are the temperatures in frostburg and coldspot. Since we're given
, we can solve for
:

Y= mx+c
So m= the gradient (slope)
And c=the y intercept (x,y= -3,4)
So it should be
Y=1/3x+4
From the given density function we find the distribution function,

(a)



(b)



(c)



Anything which have their degree as 0 is always equal to 1
=> 5^0=1
Option 3 is the answer..!!
Hope this helps you!!
Good Luck!
