Answer:

156 in^2

Step-by-step explanation:

find the areas of all the faces and add them up

area of a rectangle: bh

area of a trapezoid: \frac{1}{2} (b_1 + b_2)(h)

(5*3)+(6*3)+(5*3)+(3*12)+2(\frac{1}{2}*(6+12)*4) \\=15+18+15+36+2(\frac{1}{2}*18*4)\\=84+2(36)\\=156

the area of the trapezoid is multiplied by 2 because there's a top and bottom

Pete adds 78 to the fata set below. 20,32,32,45,50. Which statement below will be true?
ozzi

Answer:

the inter-quartile range will increase

Step-by-step explanation:

The initial data-set was;

20,32,32,45,50

Adding a new value 78 will have several effects;

The mean of the new set of values will increase since 78 is mostly likely to be an outlier.

The median of the new data set will increase. The median of the old data set is 32 while that of the new data set will be 38.5

The mode is the most frequent observation. Both the new and the old sets of values will have a mode of 32. The mode will therefore remain the same.

The inter-quartile range just like the range will increase
