Given matrices S and T below, which statement is true?

2 answers:

8 0

The matrices are
S =(4 11 T= ( -8 11
-3 -8) 3 4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
ST will be
( 4 11 × (-8 11 = ( 1 0
-3 -8) -3 -4) 0 1)
and also TS
( -8 11 × (4 11 = ( 1 0
-3 -4) -3 -8) 0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I

v={x,y,z} such that the points satisfies x-2y+3z=0. is v vector space? if not,find all for which v is not a victor space

atroni [7]

Yes, the set of vectors

V = {(x, y, z) : x - 2y + 3z = 0}

is indeed a vector space.

Let u = (x, y, z) and v = (r, s, t) be any two vectors in V. Then

x - 2y + 3z = 0

and

r - 2s + 3t = 0

Their vector sum is

u + v = (x + r, y + s, z + t)

We need to show that u + v also belongs to V - in other words, V is closed under summation. This is a matter of showing that the coordinates of u + v satisfy the condition on all vectors of V:

(x + r) - 2 (y + s) + 3 (s + t) = (x - 2y + 3z) + (r - 2s + 3t) = 0 + 0 = 0

Then V is indeed closed under summation.

Scaling any vector v by a constant c gives

cv = (cx, cy, cz)

We also need to show that cv belongs to V - that V is closed under scalar multiplication. We have

cx - 2cy + 3cz = c (x - 2y + 3z) = 0c = 0

so V is need closed under scalar multiplication.

If I roll a fair, regular six-sided die four times, what is the probability that I will roll the number exactly three times

lions [1.4K]

The probability that I will roll the number exactly three times is 0.0038.

According to the statement

we have given that the a six-sided die is rolled a four times and we have to find the probability that I will roll the number exactly three times.

So, We know that the

Probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

And the probability of rolling any number on the die is 1/6.

And

when i want to get a exactly three number than the probability become:

So,

The probability that I will roll the number exactly three times = 1/6 *1/6 *1/6 *5/6

Then solve it

The probability that I will roll the number exactly three times = 1/216 * 5/6

here 5/6 is the probability of that numbers which are not come.

So,

The probability that I will roll the number exactly three times = 5/1296

The probability that I will roll the number exactly three times = 0.0038.

So, The probability that I will roll the number exactly three times is 0.0038.
