Answer: Choice F) x \le -5

====================================================

Explanation:

One long rectangle represents x. Four of them represent 4x

One tiny unshaded square represents a unit 1. Specifically this value is positive. We have 2 columns and 6 rows, so there are 2*6 = 12 tiny squares.

So the stuff in the first box (the four long rectangles and the 12 tiny unshaded squares) represent the expression 4x+12

The stuff in the second box is -8 since we have 8 shaded squares each shaded square being -1.

----------------

The inequality we need to solve is 4x+12 \le -8

We'll subtract 12 from both sides, then divide both sides by 4 to fully isolate x

This is what the steps would look like:

4x+12 \le -8\\\\\\4x+12-12 \le -8-12 \  \text{ subtract 12 from both sides}\\\\\\4x \le -20\\\\\\\frac{4x}{4} \le \frac{-20}{4} \  \text{ Divide both sides by 4}\\\\\\x \le -5\\\\\\

The inequality sign does not flip since we did not divide both sides by a negative number.

C(5,4)(.40)^4(1-.40)^1=5(.4)^4(.6)^1=0.0768

That's 7.68% = 7.7% (rounded)

Note: C(5, 4) is the number of combinations of 5 things taken 4 at a time. You may have seen this written as _5C_4

In general, C(n,r)=\frac{n!}{r!(n-r)!}
