Suppose you select a number at random from the sample space, {-3, -2, -1, 0, 1, 2, 3, 4}. Find the probability. P(the number is less than 2 | the number is less than 4.)

Select one:
a. 5/8
b. 7/8
c. 5/7
d. 2/4

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

1/800 is the right answer

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
