Answer:
Correct group: fourth image
Surface area = 32 in2
Step-by-step explanation:
The dimensions required is 2 x 3 x 2, so in one dimension we need 2 cubes, in a second dimension we need 3 cubes, and in the third dimension we need 3 cubes.
In the first image, we have a 2 x 3 x 3 prism.
In the second image (to the right of the first one), we have a 2 x 4 x 1 prism.
In the third image (below the first one), we have a 3 x 4 x 1 prism.
In the fourth image, we have a 2 x 3 x 2 prism, so this is the correct option.
The surface area os this prism is 2*(2*2) + 2*(2*3) + 2*(2*3) = 8 + 12 + 12 = 32 in2

C
Step-by-step explanation:
Answer:
a) A = π30² = 900π cm² ≈ 2,827 cm²
b) V = Ah = 900π80 = 72000π cm³ ≈ 226,195 cm³

Answer:
3.
If a conditional statement is written in the form “If p then q”, how is the inverse of the conditional statement written?
If not q, then not p
If not p, then not q
If not q then p
If not p then q
To write the inverse of a conditional statement, you use the "opposite" of the hypothesis and the conclusion in a conditional statement.

Answer:
4.78125
Step-by-step explanation:
Step 1
Find the mean
Mean = Sum of Terms/Number of Terms
Mean = 7+5+ 16+20+ 17+ 9+ 18+ 15/8
= 107/8
= 13.375
Step 2
Find the Mean Absolute Deviation
Mean Absolute Deviation formula = |x - Mean|/n
Mean Absolute Deviation =[ |7 - 13.375| +| 5 -13.375|+ |16 - 13.375| + |20 - 13.375| +| 17 - 13.375| + |9 - 13.375 | +| 18 -13.375|+|15 - 13.375|] /8
Mean Absolute Deviation = 4.78125
Therefore, the Mean Absolute Deviation (M.A.D.) for these students = 4.78125
