Answer:
0.505 = 50.7% probability of a negative test.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
142 + 6 = 148 people tested positive. Of those, 142 had the disease and 6 did not.
7 + 145 = 152 people tested negative. Of those, 7 had the disease and 145 did not.
Find the probability of getting someone who tests negative, given that he or she did not have the disease.
This is the probability of a negative test.
152 negative tests out of 148 + 152 = 300
152/300 = 0.507
0.505 = 50.7% probability of a negative test.
Answer:
The area of the larger parallelogram is 
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is the scale factor
Let
z------> the scale factor
step 2
Find the area of the larger parallelogram
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z------> the scale factor
x------> the area of the larger parallelogram
y-------> the area of the smaller parallelogram
so
we have
substitute the values
