Well to answer this question you need to look at how many burgers were sold, and how much beef was in the burgers, then you can find your answer. You know that there are 200 grams of ground beef going into each burger. 200 grams is equal to 2 kilograms. Then you can multiply 2 (kilograms of beef per burger) by the number of burgers sold (467) which gives you a final answer of 934 kilograms.
Based on the accuracy of the test and the probability of Kevin having the disease, the following are true:
- Probability that Kevin has diabetes and the test predicts this = 0.6375.
- Probability that Kevin has diabetes and the test doesn't predicts this = 0.1125.
- Probability that Kevin doesn't have diabetes and the test predicts this = 0.2125.
- Probability that Kevin doesn't have diabetes and the test doesn't predicts this = 0.0375.
<h3>Probability that Kevin has diabetes and the test predicts this</h3>
= Probability that Kevin has diabetes x Accuracy of test
= 0.75 x 0.85
= 0.6375
<h3>Probability that Kevin has diabetes and the test doesn't predicts this</h3>
= Probability that Kevin has diabetes x (1 - Accuracy of test )
= 0.75 x ( 1 - 0.85)
= 0.1125
<h3>Probability that Kevin doesn't have diabetes and the test predicts this</h3>
= Probability that Kevin doesn't have diabetes x Accuracy of test
= ( 1 - 0.75) x 0.85
= 0.2125
<h3>Probability that Kevin doesn't have diabetes and the test doesn't predicts this</h3>
= Probability that Kevin doesn't have diabetes x (1 - Accuracy of test )
= ( 1 - 0.75) x (1 - 0.85)
= 0.0375
In conclusion, the probability depends on the accuracy of the test and the probability of having diabetes.

Part 1 :Using a variable, write an expression that describes the total amount of money earned by both boys at the end of the month.
Let the number of lawns mowed be = x
Earnings of Amar = 20x
Earnings of Sang = 15x
So total earnings are =
Part 2: Amar and Sang mowed 10 lawns each by the end of the month. They need $400 for a summer trip. Do they have enough money for their trip?
Total number of lawns mowed by each are = 10
Amar earned =
Sang earned =
So, total money earned = = $350
No, they don't have enough money for their trip. They are short of $50.
