Answer:
0.049
4.9 % of probability
Step-by-step explanation:
The probability of having the disease is equal to 7%
The probability of testing positive, having the disease is equal to 70%
We are looking for the probability of testing positive.
For that, we need to multiply the probabilities to find the result
P = (0.07)*(0.7)
P = 0.049
P = 4.9%
60 and 2x are vertical angle which means that they are congruent.
2x = 60
Now use the equation to solve for x.
2x = 60
x = 60/2
x = 30
Hope this helps :)
Answer:
13/15
Step-by-step explanation:
I assume you mean the ratio 4/5 : 12/13
Ratio means division, so it's 4/5 / 12/13
Multiply by reciprocal: 4/5 * 13/12 = 13/15
subtract 3 from both sides to isolate the variable
Z + 3 -3 = -6 -3
Z + 0 = -9
Z = -9
Answer:
Step-by-step explanation:
k/4+3=14
Move 3 over
k/4=11
Divide both sides by 4
k=11/4
k=2.75 or 2 3/4
