The probability that Andrew has heart disease is 0.9. Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it?
Answer: The probability that Andrew has heart disease
Also we know that the accuracy rate of test or
The given two events are independent.
Therefore, the probability that Andrew has heart disease and the test accurately predicts it
Answer:
there are 18 girls
Step-by-step explanation:
for every 2 boys there are 3 girls
so then you can say 2/5 of the class are boys and 3/5 are girls
and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.
Hope this helps
Answer:
C. v < (3au - 60)/2b
Step-by-step explanation:
Given
au/2 - bv/3 > 10
Required
Solve for v
We start by rewriting the inequality
au/2 - bv/3 > 10 becomes
½(au) - ⅓(bv) > 10
Multiply both sides by 6
6 * ½(au) - 6 * ⅓(bv) > 6 * 10
3au - 2bv > 60
Make -2bv the subject of formula
-2bv > 60 - 3au
Multiply both sides by -½
[When multiplying or dividing an inequality by a negative number, the sign of the inequality will change]
-½ * -2bv < -½(60 - 3au)
bv < -½(60 - 3au)
bv < ½(3au - 60)
bv < (3au - 60)/2
Divide both sides by b
v < (3au - 60)/2b
Option C is correct
