Answer:

BC= 20 units

Step-by-step explanation:

Since ∆ ABC is an equilateral triangle, all the sides are equal in length.

AC= BC

=>-y+23= 6y+2

=>-y-6y= 2-23

=>-7y= -21

=>y= 21/7

=>y= 3

BC = 6y+2 = 6(3)+2 = 18+2 = 20 units

A statewide real estate sales agency, Farm Associates, specializes in selling farm property in the state of Nebraska. Its record

faltersainse [42]

Answer:

The right answer is "1.818".

Step-by-step explanation:

The given values are:

a = 0.1

$\bar{x} = 94$

$\mu = 90$

Now,

The test statistic will be:

⇒ $t=\frac{\bar{x}-\mu}{\frac{s}{vn} }$

On substituting the given values, we get

⇒ $=\frac{94-90}{\frac{22}{10} }$

⇒ $=\frac{4}{2.2}$

⇒ $=1.818$

Show that a discrete metric on a vector space X≠{0} cannot be obtained from a norm (the pair (X,d) is called the discrete metric

topjm [15]

You know that the discrete metric only takes values of 1 and 0. Now suppose it comes from some norm ||.||. Then for any α in the underlying field of your vector space and x,y∈X, you must have that

∥α(x−y)∥=|α|∥x−y∥.

But now ||x−y|| is a fixed number and I can make α arbitrarily large and consequently the discrete metric does not come from any norm on X.

Step-by-step explanation:
