Answer:
The two ordered pairs you can use is (4, 3) and (8, 4). You can plot these and draw a straight line through these.
Step-by-step explanation:
In order to find the graph of the follow, first solve for y.
-8 + x = 4y - 16
-4y - 8 + x = -16
-4y -8 = -x - 16
-4y = -x - 8
y = 1/4x + 2
Now that we have this, we can find two points by choosing any two x's and solving for the y. For this case, we'll use 4 and 8.
y = 1/4x + 2
y = 1/4(4) + 2
y = 1 + 2
y = 3
So the first ordered pair is (4,3)
y = 1/4x + 2
y = 1/4(8) + 2
y = 2 + 2
y = 4
So the second would be (8. 4)
Answer:
It is provided that 10% of the men aged 55 to 64 have cholesterol level <u>270 mg/dl</u> or higher.
Step-by-step explanation:
Let <em>X</em> = blood cholesterol levels of men aged 55 to 64 years.
The random variable <em>X</em> follows a Normal distribution with mean <em>μ</em> = 222 mg/dl and standard deviation <em>σ</em> = 37 mg/dl.
It is provided that 10% of the men aged 55 to 64 have cholesterol level <em>x</em> mg/dl or higher.
Compute the value of <em>x</em> as follows:
Use the <em>z</em>-table to compute the value <em>z</em> for the probability 0.90.
The value of <em>z</em> is 1.29.
Compute the value of <em>x</em> as follows:
Thus, 10% of the men aged 55 to 64 have cholesterol level 270 mg/dl or higher.

Answer:
100yd
Step-by-step explanation:
Let the width of the rectangle be x yd
Length will be 4x yd
Area = Length × width
400yd² = 4x(x)
4x² = 400yd²
Dividing by 4 throughout gives;
x² = 100 , x = 10yd
So x (width) = 10yd
Length = 4(10) = 40yd
Perimeter = 2( length + width)
Perimeter = 2(40 + 10) = 2(50) 100yd
