Answer:
B
Step-by-step explanation:
We do not know how fast Sally or Sue is.
If Sally ran at a speed of x, and Sue at a speed of y, we have an equation as follows:
x = 2y
The total paid (including down payment) is
650×0.75+24.38×12=780.06
The finance charge in dollars is
780.06−650=130.06
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.
