Lin ran 2 3/4 miles in 2/5 of an hour, noah ran 8 2/3 miles in 4/3 of an hour, how far would noah run in 1 hour?

The distance cover by Noah in 1 hour to cover distance is 6.5 miles

Step-by-step explanation:

Given as :

The distance cover by Lin = 2 miles = miles

The time taken to cover distance by Lin =   hours

Again

The distance cover by Noah = 8 miles = miles

The time taken to cover distance by Noah =   hours

Let the distance cover by Noah in 1 hour = d miles

∵ The distance cover by Noah in hours = miles

∴ The distance cover by Noah in 1 hour =

I.e d = miles

or, d = = 6.5 miles

So, The distance cover by Noah in 1 hour = d = 6.5 miles

Hence, The distance cover by Noah in 1 hour to cover distance is 6.5 miles Answer

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
