Answer:
a) 0.10425
b) 0.00475
c) 0.04975
d) 0
Step-by-step explanation:
a) Pr (the test result will be positive) = (0.95 × ) + ( 0.10 × )
= 0.00475 + 0.0995
= 0.10425
b) Pr (positive result, the person is a sufferer) = 0.95 x
= 0.00475
c) Pr (negative result, non sufferer) = (1-0.95) x
= 0.04975
d) Pr ( person misclassified) = 0
Scale = 88 feet/5.5 inch = 16ft/inch or 16 feet = 1 inch Width = 76 feet x 1 inch/16 feet = 4.75 inches.
Subst. the given x and y values: 6(-1)^4 * (3)^3
6 * 27 = 162
Note that you MUST do the exponentiation first.
Also note that your post would be much clearer if you'd please use " ^ " to denote exponentiation: 6x^4 * y^3

Answer:</h3>
A) Shading is below the line y=2x-7, and that line is dashed. Shading is above the line y=-x/2+3, and that line is solid. The solution area is where the shading overlaps.
B) No. It fails to satisfy the second inequality.
<h3>
Step-by-step explanation:</h3>
Part A. The boundary line of the first inequality has a slope of +2 and a y-intercept of -7. Since allowed y-values are less than those on this line, the line is dashed and the shading is below the line. The solution space is shown with blue shading in the attachment.
The boundary line of the second inequality has a slope of -1/2 and a y-intercept of +3. Allowed values of y are equal to or greater than those on this line, so the line is solid and shading is above the line. The solution space is shown with green shading in the attachment.
The solution space is where the shaded areas overlap, generally to the upper right of the graph.
Part B. The point (3, -7) is in the shaded area for the first inequality, but not for the second. It does not meet the requirement for y ≥ -1/2x +3. You can see this when you substitute the point values:
-7 ≥ -1/2(3) +3 ⇒ -7 ≥ 3/2 ⇒ FALSE
