Answer:
Mean is 6
Step-by-step explanation:
Mean refers to the average of the observations.
Let X be the number of different sweaters I wore during a 5-day week.
Possible values of X = 1, 2, 3, 4
For X = 1,
For X = 2,
For X = 3,
For X = 4,
To find: Mean
Solution:
Answer:
x= 1/2
y=3
Step-by-step explanation:
it is easier to subtract both equation and obtain a new one
1) 6x+0.4y=4.2
2) -4x+0.4y=-0.8
---------------------------------
1) -2)= 10x+0=5 leading to x=1/2
Now just eval x=1/2 in any of the original equations, for instances
1) 6*(1/2) +0.4*y=4.2, which leads to y=3
The formula to be followed for the calculation of simple interest is F = P (1 + in) where F is the future worth, P is the present worth, i s the annual interest rate and n is the number of years. In this case, F = $275 * (1+ 0.08*16) = $627. The interest earned is $627 - <span>$275 equal to $352.</span>
Step-by-step explanation:
a×10⁰×a
<em>Since,</em><em> </em><em>m⁰</em><em>=</em><em>1</em><em> </em><em>therefore</em>
a×1×a
a²
The least common multiple of 9,12,15 is 180
