If a=(-1, -3) and b=(11, -8) what is the length of ab?
professor190 [17]

Answer: D.  The length is 13 units.

Step-by-step explanation:

(-1, -3 )    Find the difference between the x values and y values.

 (11, -8)  

-3-(-8) = 5

-1-11 =   -12    now find the  absolute values.

The absolute value of 5 is 5 .  The absolute value of  -12 is 12.

Now use the Pythagorean Theorem formula a^2 + b^2 =c^2  where c square is the length between AB.

5^2 + 13^2 = C^2

25 + 144 = c^2  

169=c^2

c= 13

Let A be an m x n matrix and let b be a vector in RM. Three of the following four statements are all equivalent to each other. C
rusak2 [61]

Answer:

A.

Step-by-step explanation:

From the given information:

If A = m × n matrix

where;

b  is a vector in R^m

Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.

This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.

Option c and d are equivalent, also option b and c are equivalent.

P (a) =2/5 p(b)=1/4 ( a and b=1/25I did two events independent or dependent please help
juin [17]

we have

p (a) =2/5 p(b)=1/4 ( a and b=1/25

Remember that

we know that for two independent events A,B.

⇒ P(A∩B)=P(A)*P(B)

we have

P(A)=2/5 and P(B)=1/4

so

P(A∩B)=(2/5)*(1/4)=2/20=1/10

that means

<h2>events are dependent</h2>
