The area of the shaded region will be the area of the rectangle minus the area of the white square inside of it:
((x+10)(2x+5)) - ((x+1)(x+1))
First, FOIL both of the areas separately:
(2x^2 + 5x + 20x + 50) - (x^2 + x + x + 1)
Simplify within the parentheses by adding like terms:
(2x^2 + 25x + 50) - (x^2 + 2x + 1)
Now, subtract one equation from the other:
2x^2 + 25x + 50
-x^2 - 2x - 1
= x^2 + 23x + 49
This will be the equation for the area.
Answer:
Step-by-step explanation:
Another way to express 56 is because they are equal values.
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The sample size is n = 175
The population proportion is p = 0.45
Generally the mean of the sampling distribution is
Generally the standard deviation is mathematically represented as
=>
=>
Generally the probability of that the sample proportion of orange candies will be between 0.35 and 0.55 is
=>
Generally
So
=>
From the z-table
and
So

Answer:<u>
158.7 is the answer</u></h2><h2><u>or it can be</u>
<u>89.7</u></h2>
Step-by-step explanation:
<h2>
<u>69 + Percentage increase =
</u></h2><h2>
<u>69 + (130% × 69) =
</u></h2><h2>
<u>69 + 130% × 69 =
</u></h2><h2>
<u>(1 + 130%) × 69 =
