Answer:

  (x, y) = (-6, -4)

Step-by-step explanation:

The solution can be found quickly using a graphing calculator. It is the point of intersection of the two lines.

_____

If you like, you can solve the system algebraically. The second equation can be rewritten to give ...

  y = x +2

Substituting this into the first equation gives ...

  5/3x -2(x +2) = -2

  -1/3x -4 = -2

Adding 4 and multiplying by -3 gives ...

  x = -3(-2+4) = -6

Then our equation for y tells us ...

  y = -6 +2 = -4

The solution is (x, y) = (-6, -4).

aev [14]

Answer:

a) We conclude that the menager use the hypergeometric distribution.

b) We conclude that the menager use the binomial distribution.

Step-by-step explanation:

a) We know that in probability theory, the hypergeometric distribution is a discrete probability distribution that describes the probability of k successes in n draws, without replacement.

We conclude that the menager use the hypergeometric distribution.

b) We know that the binomial distribution describes the probability of k successes in n draws with replacement.

We conclude that the menager use the binomial distribution.

How do you find the surface area if your radius is 5 and your length is 10
ser-zykov [4K]
Surface Area of a Cone = (pi)*(radius)*(radius) + (pi)*(radius)*(length)

radius = 5
length = 10

SA = 25pi + 50pi = 75pi or about 235.619
