The number of hours spent in an airplane on a single flight is recorded on a dot plot. The mean is 5 hours and the standard deviation is approximately 5.82 hours. The median is 4 hours and the IQR is 3 hours. The value 26 hours is an outlier that should not have been included in the data.
When the outlier is removed from the data set:
Here is a graph of the equation \(3x-2y=12\).
Select all coordinate pairs that represent a solution to the equation.
Line graphed on a coordinate plane, origin O. Horizontal axis from negative 2 to 6, by 2’s. Vertical axis from negative 6 to 2, by 2’s. Line goes through 0 comma negative 6, 2 comma negative 3, and 4 comma 0.

Jada bought some sugar and strawberries to make strawberry jam. Sugar costs \$1.80 per pound, and strawberries cost \$2.50 per pound. Jada spent a total of \$19.40.
Which point on the coordinate plane could represent the pounds of sugar and strawberries that Jada used to make jam?
Graph of a line, origin O. Horizontal axis, sugar, pounds, scale is 0 to 12, by 1’s. Vertical axis, strawberries, pounds, scale is 0 to 9, by 1’s. Line starts at 0 comma 7 point 7 5 and passes through 4 comma 5, and 8 point 2. Point A, 0 comma 0, point B 8 comma 2, point C 6 comma 1, and point D 7 comma 5 are identified.
