Question
The scatterplot above shows the numbers of grams of both total protein and total fat for eight sandwiches on a restaurant menu. The line of best fit for the data is also shown. According to the line of best fit, which of the following is closest to the predicted increase in total fat, in grams, for every increase of 1 gram in total protein?
- 2.5
- 2.0
- 1.5
- 1.0
The correct answer is: 1.5
HINT – Increase in total fat for every increase of 1 g in total protein is given by slope of the line of best fit.
SOLUTION – We require two points to find the slope of the line of best fit.
Observing the line of best fit let first point be x1 = 10 , y1 = 20 and second point be x2 = 35 , y2 = 55. ( approx. values)
Slope of the line of best fit = 
Since closest value is asked in the question,
Option C is true
A gram of Carbohydrates contain '4' calories, a gram of protein contains '4' calories, and a gram of fat contains '9' calories. Because one gram of fat contains '9' calories, divide the total number of calories by 9. 400, calories divided by 9 equals 44 grams. Then multiply 700 calories by 9 to obtain 78 grams.
To calculate total fat, look for the amount of fat found per serving of food in grams to determine its fat content. For example, if '1' teaspoon of butter weighs 4.7 grams and contains 3.8 grams of fat, you'll know that fat makes up about 80% of its weight.

The scatterplot above shows data for ten charities along with the line of best fit. For the charity with the greatest percent of total expenses spent on programs, which of the following is closest to the difference of the actual percent and the percent predicted by the line of best fit?
Expenses are sums of money spent on goods or services. It is defined as the amount of money required to obtain something."It takes money to make money," as the adage goes. Supplier payments, employee wages, factory leases, and equipment depreciation are all everyday expenses.
For example, running a car can be costly in terms of fuel, repairs, and insurance.
Profit (P): When a product is sold for more than its cost, the seller makes a profit.
Loss (L): When a product is sold for less than its cost, the seller suffers a loss.
