What's the anewer to this
21×__=9×21
tell which property you used 21×=9×21
property of multiplication..

The correct answer is 9.

Step-by-step explanation:

Multiplication property of equality is defined as the property in which the a number multiplied on one side of the equation must be multiplied to the other side of the equation with the same sign.

c is multiplied on both the sides of the reaction.

In the given question:

Thus, the value of 'x' will be 9 by associative property.

P(x<10) =0

Step-by-step explanation:

M =1/μ

M= 1/15 =0.066667

X- Exp (0.066667)

Where: X is the random variable for number of days

P (X<x) = 1 - e^-mx

P(X - x) = 1 - e^-0.06666 x10

P(x<10) = 0
