Let
x = salesperson's weekly paycheck
y = second salesperson's paycheck
We have the following system of equations:
x + y = 1025
x = 1.40y
Solving the system:
x + y = 1025
1.40y + y = 1025
2.40y = 1025
y = 1025 / 2.40 = 427.0833333 $
x = 1.40y
x = 1.40 * (427.0833333) = 597.9166666 $
answer:
the amount of each paycheck is:
first persons paycheck = 597.92 $
second persons paycheck = 427.08 $
Answer:
2/7
Step-by-step explanation:
Since 4 out of 14 times it landed on blue, it must have a 4/14 experimental probability of 4/14 for landing on blue. 4/14 simplifies to 2/7.
Answer:
a) 0.9548
b) 0.0452
Step-by-step explanation:
Specificity of test:
The specificity of a test is the true negative rate, that is, the proportion of people without the disease that test negative.
Sensitivity of test:
The sensitivity of a test is the true positive rate, which is the proportion of people with the disease that test positive.
a. What proportion of the people who test positive for Malaria would we expect to actually have the disease?
This is the sensitivity of the test, which is of 95.48%, so the proportion if 0.9548.
b. What proportion of people who test positive for Malaria will not have the disease?
True positive rate is of 95.48%.
1 - 0.9548 = 0.0452
So the proportion of people who test positive for Malaria will not have the disease is 0.0452.
