If one pot of paint covers an area of 5m2. How many pots will be needed to cover the floor?​

 2 pots

Step-by-step explanation:

area of the floor = length     x   width

                           = 400 cm   x   250 cm

                           = 100 000 cm²

5 m²  = 5  x  10 000 cm² =  50 000 cm²

number of pots needed = area of floor   ÷  area covered by one pot

                                        = 100 000 cm²  ÷  50 000 cm²

                                        =  2 pots

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

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
