It takes Cayson 2.5 hours to get from house to the stadium and it takes Riley 3 hours to get from house to the lake. In total they spent 5.5 hours to overcome the distance 385 mi.

Use formula:

$D=rt,$ where D is distance, r - speed and t - time.

Thus,

$385=r\cdot 5.5,\\ \\r=70$ mi/h.

Answer: 70 mi/h.

In a homicide case 33 different witnesses picked the same man from a line up. the line up contained 5 men. if the identification

polet [3.4K]

the correct question in the attached figure

we know that

the probability
that a witness picks a particular person by chance-----> P=1/5

the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128

the answer is the option B 0.0000128

There are a variety of problems in which the number of witnesses change, for example
....find the probability that all 9 witnesses would pick the same person

in this case, the probability would be-------> P=1/5^9=0.000000512

What is the sum of interior angles for a nonagon

alexira [117]

Remember your prefixes! They help a lot, because there is a formula for this particular problem. Nonagon refers to a shape with 9 sides.

The number of triangles a polygon has is represented by the formula:
(n-2)

Where "n" is the number of sides. If you ever forget what you subtract "n" by think of a triangle. It has 3 sides, so it is only logical that you should only have 1 triangle (subtract by 2). So, what is the sum of the interior angles of a triangle, 180°. So the formula looks like this:

Sum of Interior Angles = 180°(n-2)
180°(9-2)
180°(7) = 1260° is the sum of interior angles for a nonagon!

If segment RS has M(8,-2) and coordinates R(10,5) then what are the coordinates of point S?

Brums [2.3K]

If M is the midpoint of segment RS, then

M = (R + S)/2

2M = R + S . . . . . multiply by 2

S = 2M - R = 2(8, -2) -(10, 5) = (6, -9) . . . . put in the given values
