Answer:
of favourable events = 4, (which includes 1, 4, 9, 16). And, total number of observations are 20. So, the probability of picking a square number between 1 and 20 is 1/5.

Answer: 1
==========================
Explanation:
To average a bunch of numbers, we add them up and divide by how many numbers there are. In this case, we'll divide by 3 since there are 3 numbers.
Add up the values: m+n+(-1) = m+n-1
Divide by 3: (m+n-1)/3
Set this equal to 0 since we're told the average is 0: (m+n-1)/3 = 0
Now let's isolate m+n. It might help to replace "m+n" with another variable, say P to get (P-1)/3 = 0.
Solve for P
(P-1)/3 = 0
P-1 = 3*0 .... multiply both sides by 3
P-1 = 0
P = 1 ... add 1 to both sides
m+n = 1 .... replace P with m+n
So that's why the answer is 1
Answer:
C
Step-by-step explanation:
Answer:The value of m for the given equation is, 35
Step-by-step explanation:
Given an equation: https://tex.z-dn.net/?f=x%5E%7B3m%7D%3D(x%5E%7B65%7D)*(x%5E%7B40%7D)
Use the above property on RHS in equation [1];
Since the base are same i.e, x ; we can add the exponents.
or
Using: , then a=b.
Therefore, 3m=105.
Divide 3 on both sides of an equation:
Simplify:
m=35
Therefore, the valur of m is, 35.
