Answer:
(-20 - 10) / (-12 - (-10))
-30 / -2
30/2
now the midpoint would be half the two points
30/2 ÷ 2/2 = 15/1
So add 15 to -20 (or subtract 15 from 10) for the y, and add 1 to -12 (or subtract 1 from -10) for the x.
The area under the curve between the two values is (d) 0.0750
<h3>How to determine the area?</h3>
From the table, we have:
P(z = -0.45) = 0.3264
P(z = -0.67) = 0.2514
The area under the curve is calculated as:
Area = P(z = -0.45) - P(z = -0.67)
So, we have:
Area = 0.3264 - 0.2514
Evaluate the difference
Area = 0.0750
Hence, the area under the curve between the two values is (d) 0.0750

Answer:
Length: 40 inches
Width: 10 inches
Step-by-step explanation:
Let 
width of the rectangle.
From the information "length of a rectangle is four times its width", we can express the length as:
Length = 
- - - -
Perimeter = 
(formula for perimeter of rectangle)
(combine like terms)
inches
∴ The width of the rectangle is 10 inches.
To find the length of the rectangle, we can use substitution:
Length =
inches
∴ The length of the rectangle is 40 inches.
