9) Area of Figure = Area of rectangle + area of triangle
A = 17 * 22 + (1/2 * 12 * 19)
A = 374 + 114
A = 488 cm²
10) Area of Figure = Area of rectangle + area of triangle
A = 8 * 4 + (1/2 * 3*4)
A = 32 + 6
A = 38 cm²
Hope this helps!
True mean = mean+/- Z*(SD/sqrt (n))
Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages
Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
