Answer:

2,586

Step-by-step explanation:

Add 1000+1000

2000

Since its 999 not 1000 subtract 1

1999

Now add 1 and subtract 1 from 587

Then add 2000 with 586

2,586

To the nearest degree, what is the measure of each exterior angle of a regular decagon?
aniked [119]

Answer:

Exterior angle of a decagon will be 36°

Step-by-step explanation:

Measure of all interior angles of a polygon is represented by (n - 2)×180°

where n is the number of sides of the polygon.

Now we have to calculate the exterior angle of a regular decagon.

As we know exterior angle of polygon is supplementary of the interior angle.

So we will calculate interior angle first.

Sum of interior angles of decagon = (n - 2)×180° = 8×180° = 1440°

Since decagon is regular so all angles will be same.

So one angle of decagon = 1440 ÷ 10 = 144°

Now exterior angle = 180 - 144 = 36°

Each exterior angle of a decagon will be 36°.

Does anyone know this answer??
Aleonysh [2.5K]

For this case we have the following equation:

(2x + 3) ^ 2 + 8 (2x + 3) + 11 = 0

Let u = 2x + 3

We have:

u ^ 2 + 8u + 11 = 0

By definition, given an equation of the form ax ^ 2 + bx + c = 0

The quadratic formula, to find the solution can be written as:

x = \frac{-b+/-\sqrt{b ^ 2-4 (a) (c)} }{2(a)}

In this case we have:

a = 1\\b = 8\\c = 11

Substituting in the quadratic formula we have:

Option B

The 200 meter race times at a state track meet are normally distributed with a mean of 13.56 seconds and a standard deviation of
storchak [24]

The approximate probability that a runner chosen at random will have a 200 meter time less than 13.5 seconds is 0.4880 ⇒ A

Step-by-step explanation:

To find the probability of a random variable X which has a normal distribution do that

  • If X < b, find the z-score using the formula z = (b - μ)/σ, where μ is the mean and σ is the standard deviation
  • Use the normal distribution table of z to find the corresponding area to the left of z-score

∵ The 200 meter race times at a state track meet are normally

   distributed with mean of 13.56 seconds and a standard deviation

   of 2.24 seconds

∴ μ = 13.56

∵ σ = 2.24

- We need to find the probability that a runner chosen at random

   will have a 200 meter time less than 13.5 seconds

∵ X < 13.5

∴ b = 13.5

- Find z-score

∵ z=\frac{13.5-13.56}{2.24}=-0.02679

- Use the normal distribution table to find the area corresponding to z

∵ The corresponding area of z ≅ -0.03 is 0.4880

∴ P(x < 13.5) = 0.4880

The approximate probability that a runner chosen at random will have a 200 meter time less than 13.5 seconds is 0.4880
