Answer:
#1 x=3 (the furthest to the left on top)
#2 x=4 (below both questions)
#3 x=2 (farthest to the right)
Step-by-step explanation:
Answer:
x(x+3).
Step-by-step explanation:
The C, D. of x and x+3 is x(x+3).
It should be noted that the mean and the standard deviation of the data given in will be 4.26 and 1.1011 respectively.
<h3>How to solve
the mean.</h3>
From the complete information, the mean will be calculated as:
= (0.02 × 1) + (0.09 × 2) + (0.12 × 3) + (0.15 × 4) + (0.62 × 5)
E(X) = 4.26
The standard deviation will be calculated thus:
E(X²) = (0.02 × 1²) + (0.09 × 2²) + (0.12 × 3²) + (0.15 × 4²) + (0.62 × 5²)
E(X²) = 19.36
The standard deviation will then be the difference between the square root of 19.36 and 4.26². This will be 1.1011.
The expected profit of the company will be:
= 0.75 × E(X)
= 0.75 × 4.26
= $3.20
The mean of the total number of binders purchased will be:
= 4.26 + 2.74 = 7
The standard deviation will be 1.6658.
Lastly, the total expected profit will be:
= 0.75E(X) + 1.45E(Y)
= 0.75(4.26) + 1.45(2.74)
= 3.195 + 3.973
= 71.68

Answer:
The equation of a circle is 
.
Step-by-step explanation:
-The equation of a circle is:
(where center is 
, the point 
and the radius known as 
).
-Use the center (5,-4) and the point (5,-2) for the equation:
-Solve the equation:
-After you found the radius, use the center (5, -4) and radius 2 to get the equation of a circle:
-Then, after you have the equation, the radius needs to simplified by the exponent:
