Consecutive angles in a paralleogram have sum 180
And
- 7y+3+86=180

- 7y=91
- y=13
And
opposite angles are equal
Answer:
You will have 21 positive results.
Step-by-step explanation:
Sensitivity of test:
Is the true positive rate, that is, the proportion of positive results that give positive tests.
Specificity of test:
True negative rate, that is, the proportion of negative results that give negative tests.
90% sensitive, 20 reliable people apply
0.9*20 = 18
95% specific, 60 unreliable people apply
1 - 0.95 = 0.05 of positive results.
0.05*60 = 3
How many positive results will you have?
18 + 3 = 21
You will have 21 positive results.
The main motive behind dealer incentives is to give the dealers a low price for stocking the companies products.

Answer:
The number of nickels, x is 4
The number of dimes, y is 16.
Explanation:
Given that Melanie has $1.80 worth of nickels and dimes, and she has 12 more nickels than dime.
Let x represent the number of nickels and y represent the number of dimes.
Then we have:
0.05x + 0.1y = 1.80 ...................................................(1)
x + 12 = y.....................................................................(2)
Solving these equations using graph as follow:
Note that the solution are the points where the lines intersect.
Here, x = 4 and y = 16
