23 boys and 11 girls were given a maths test. Their scores are listed below:
Boys: 7, 13, 15, 19, 35, 35, 37, 43, 44, 44,
45, 46, 47, 47, 49, 51, 52, 55, 55, 56,
78, 82,91
Girls: 7, 18, 23, 47,58, 63, 68, 72, 72, 75, 87
Use box plots to compare the differences between the boys
and girls scores and comment on the differences.
explore if any of the values are outliers
Calculation for outliers to use is
High Outliers > UQ + 1.5 x IQR
Low Outliers < LQ - 1.5 x IQR

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
