One-hundred students were allowed to re-take an exam for their math course. the
probability distribution shows how studying for the latest exam affected their grade
when compared with the first time they took the exam. what is the probability that a
student who studied for the exam saw an increase in their exam grade? round to the
nearest thousandth.

explanation:

step-by-step explanation:

b is the correct answer

the football players are volunteering for the test.

happy to

pls mark as brainliest

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
