Answer:
Area = 160 sq cm
Perimeter = 67.31 cm
Step-by-step explanation:
Area of the figure = Area of rectangle with dimensions 16 cm and 12 cm - Area of the right triangle with base and height ecah 8 cm.
=16*12 - 1/2 * 8 *8
= 192 - 32
= 160 sq cm
GEF is a right triangle.
Therefore, by Pythagoras theorem:
Perimeter of the figure
= 12 + 16 + 12+4+8+11.31+4
= 67.31 cm

Answer:
(a) 0.14%
(b) 2.28%
(c) 48%
(d) 68%
(e) 34%
(f) 50%
Step-by-step explanation:
Let <em>X</em> be a random variable representing the prices paid for a particular model of HD television.
It is provided that <em>X</em> follows a normal distribution with mean, <em>μ</em> = $1600 and standard deviation, <em>σ</em> = $100.
(a)
Compute the probability of buyers who paid more than $1900 as follows:
*Use a <em>z</em>-table.
Thus, the approximate percentage of buyers who paid more than $1900 is 0.14%.
(b)
Compute the probability of buyers who paid less than $1400 as follows:
*Use a <em>z</em>-table.
Thus, the approximate percentage of buyers who paid less than $1400 is 2.28%.
(c)
Compute the probability of buyers who paid between $1400 and $1600 as follows:
*Use a <em>z</em>-table.
Thus, the approximate percentage of buyers who paid between $1400 and $1600 is 48%.
(d)
Compute the probability of buyers who paid between $1500 and $1700 as follows:
*Use a <em>z</em>-table.
Thus, the approximate percentage of buyers who paid between $1500 and $1700 is 68%.
(e)
Compute the probability of buyers who paid between $1600 and $1700 as follows:
*Use a <em>z</em>-table.
Thus, the approximate percentage of buyers who paid between $1600 and $1700 is 34%.
(f)
Compute the probability of buyers who paid between $1600 and $1900 as follows:
*Use a <em>z</em>-table.
Thus, the approximate percentage of buyers who paid between $1600 and $1900 is 50%.

From the question, we have the following:
and
Substitute p for Area of Old in the second equation
Hence, the expression is:
Plot these points and then draw the line
X = 0
Y = -3
X = -1
Y = -2
X= -2
Y = -1
X = 0
Y = -3
X = -1
Y = -2
X= -2
Y = -1
Hey there.
When writing a polynomial in standard form, you always want to start from the highest degree (exponent), so let's simplify our expression before doing so.
-2
+ 6 = 4;
This number will go first as it has the highest degree.
Up next will be '-3x', as it has a degree of 1.
After this, we have 6, having a degree of 0.
Let's set up our new polynomial with this information;
4 - 3x + 6.
This is known as a cubic trinomial since it has three terms and has a degree of 3.
Your correct answer is "D.)"
I hope this helps!
