Answer:No, it didn't affect the inequality sign because we multiplied and divided by a negative number. In the 4th operation, the inequality sign changed because we divided by a negative number

jarptica [38.1K]

Answer:

60.6%

0.0003%

Step-by-step explanation:

Because they are independent events, the final probability will be the multiplication of each event, that is, 0.92 multiplied 6 times, in other words:

 0.92 ^ 6 = 0.606

that is to say that the probability that the 6 men survive is 60.6%

Now, to calculate that at least one survives, it means that 5 died, the probability that one dies is 1 - 0.92 = 0.08, and how they are 5 would be:

0.08 ^ 5 = 0.0000032768

Then multiplied by 0.92, which is that one survives, we are left with:

0.0000032768 * 0.92 = 0.00000301465

Which means that the probability of one surviving is 0.0003%, it is a very low probability because the probability of surviving is really high.

The given shape is a regular pentagon.
svetoff [14.1K]

Answer:

Step-by-step explanation:

Since there are missing data, let's discuss some facts about regular polygons and their angles.

1) The sum of its Interior angles is given by:

S_i=180^{\circ}(n-2) \therefore \:for\: a\:pentagon\:S_i=180^{\circ}(5-2) =540^{\circ}

2) Since it is a regular pentagon, each interior angle is congruent:

Each interior angle:

Interior\:angle=\frac{540^{\circ}}{5} =108^{\circ}

3) If we trace an outside line, the external angle will be supplemental, i.e.

m\angle external= 180^{\circ}-108^{\circ} \therefore= 72^{\circ}

4) If we trace from each diagonal one line segment, in a regular pentagon that will form 3 triangles with one-third of 108º,i.e.,36º

As we can see, the in the picture below
