Answer:
4. 28 sq. inch
Step-by-step explanation:
First, Area of the square = l² = 2² = 4
Area of the triangle = 1/2 x b x h
= 1/2 x 2 x 6
= 6
Total surface area = Area of square + 4 x area of triangle
= 4 + 4 x 6
= 28
The original function is given by:
We apply the following transformation:
Horizontal displacements:
Suppose k> 0
To move the graph k units to the right, we must graph f (x-k)
Applying the transformation for k = 4 we have:
Answer:
B. Right by 4 units
Answer:
The specificity of this test is expressed as:________
70%.
Step-by-step explanation:
a) Data and Calculations:
TEST RESULTS Disease Present Disease Absent Total
Positive for Factor X 40 60 100
Negative for Factor X 10 140 150
Total 50 200 250
Negative for X and Disease Absent = 140/200 * 100
= 0.7 * 100
= 70%
b) The specificity refers to the percentage of people who test negative for a specific disease among a group of people who do not have the disease. No test is 100% specific because some people who do not have the disease X will test positive for it (false positive). Therefore, we are testing for the true negative, that the 140 people who tested out of the 200 people who do not have the disease.
