Classify the polygon as regular or irregular, and concave or convex.

Svetradugi [14.3K]

Answer:

This would be a regular polygon.

Step-by-step explanation:

A regular polygon has congruent sides and interior angles.

An irregular polygon does not have congruent sides and all interior angles.

A convex polygon does not have a interior angle greater than 180°.

Lastly, a concave polygon has only one interior angle greater than 180°.

Using the process of elimination, it would not be a convex or concave polygon. Now we have either a regular or irregular polygon. This polygon can not be a irregular polygon because all the sides are congruent. This means that this polygon is a regular polygon!

A travelling salesman sells milkshake mixing machines and on average sells 8.9 machines per month. He needs to sell at least 3 m

Goshia [24]

Answer:

0.67% probability he will have to shut down after this month

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

On average sells 8.9 machines per month.

So $\mu = 8.9$

Using the Poisson distribution, what is the probability he will have to shut down after this month

If he sells less than 3 machines.

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-8.9}*8.9^{0}}{(0)!} = 0.0001$

$P(X = 1) = \frac{e^{-8.9}*8.9^{1}}{(1)!} = 0.0012$

$P(X = 2) = \frac{e^{-8.9}*8.9^{2}}{(2)!} = 0.0054$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0001 + 0.0012 + 0.0054 = 0.0067$

0.67% probability he will have to shut down after this month

The prices of a bike and T.V are in the ratio 2:3. If the bike costs 8000A.E.D. Find the price of T.V

Mrrafil [7]

Answer:

Assuming that AED is the currency:

Step-by-step explanation:

The question notes that if the TV is 3 the bike would be 2.

8000*1.5 = 12000

Answer would be 12000 AED, because you multiply the bike by 3/2

Triangle sum and exterior angle theorem.

wlad13 [49]

Did two of them for you as reference for the rest.

Explanation for #1

The sum of all the angles in a triangle is 180. Simply add the given angles. Take 180 and subtract the sum of the given angles

180 - (58 + 47) = 75

Missing angle is 75

Explanation for #4

A straight angle is 180 degrees. Same thing as the first: add the given angles then take 180 and subtract it.

Then take 180 <em>again </em>and subtract the answer you got from the first step.

180 - (21 + 34) = 125

180 - 125 = 55

The missing angle is 55
