Find u, v , u , v , and d(u, v) for the given inner product defined on Rn. u = (0, −4), v = (5, 3), u, v = 3u1v1 + u2v2
tigry1 [53]

Answer:

=-12

d(u,v)=2\sqrt{31}

Step-by-step explanation:

We are given that inner product defined on R_n

=3u_1v_1+u_2v_2

u=(0,-4),v=(5,3)

We have to find the value of <u,v> and d(u,v)

We have u_1=0,u_2=-4,v_1=5,v_2=3

Substitute the value then we get

=3(0\cdot5)+(-4)(3)=-12

Now, d(u,v)=\left \|v-u\right \|

Using this formula we get

d(u,v)=\left \| (5,7) \right \|=\sqrt{3(5)^2+(7)^2}=\sqrt{75+49}=\sqrt{124}

d(u,v)=2\sqrt{31}

If X and Y are mutually exclusive events with P(X) = 0.295, P(Y) = 0.32, then P(X⏐Y) =
Kaylis [27]

Using conditional probability, it is found that P(X⏐Y) = 0.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which:

  • P(B|A) is the probability of event B happening, given that A happened.
  • P(A \cap B) is the probability of both A and B happening.
  • P(A) is the probability of A happening.

In this problem, we have that X and Y are mutually exclusive events, hence P(X \cap Y) = 0, hence:

P(X|Y) = \frac{P(X \cap Y)}{P(Y)} = \frac{0}{0.32} = 0

Identify the postulate that proves the triangles are congruent.<br> SSS<br> HL<br> ASA<br> SAS
andrew11 [14]

Answer:

D. HL (hypotenuse leg)

Step-by-step explanation:

There are two triangles in the picture, ABQ and CDP. The condition for the hypotenuse leg are:

1. both triangles are right triangle

2. the hypotenuse and one of the leg/side is equal

Both B and D angle is 90 degrees, so both triangles is right triangle. The hypotenuse for the triangle is AQ and PC, and both are equal. One of the triangles legs also equal, which is AB and CD. With that, you fulfill HL postulate for the congruent triangle.

Don't confuse this with SAS theorem for the same angle should be on the middle of two equal sides.
