Carl has two more flips, and we want to know the probability that one and only one of those times it will be jelly side up. Assuming the basic heads/tails 50% probability each flip we have four possible outcomes: P P. P J, J P, J J, (btw P = plain side and J = Jelly side) and two of the four give us the one P wanted, so 2/4 = 50% probability.

HELP ASAP PLEASE !!!!!!!!!!!!!!
Damm [24]

Answer:

Step-by-step explanation:

Think of drawing a right triangle, with the hypotenuse connected to points A and B.  The hypotenuse, or the distance between A and B is 2√10.  2√10 is the same thing as √40.  Thus, because of Pythagorean theorem, a^2 + b^2 = 40. One combination would be a=2 and b = 6 and another would be a = 6 and b = 2.  Thus, the two places point B could be are (3,7) and (7,3).

Hope it helps <3

LUCKY_DIMON [66]

Answer with Step-by-step explanation:

We are given that v_1,v_2,..,v_4 are in R^4 and v_1,v_2,v_3 is linearly dependent then {v_1,v_2,v_3,v_4}[/tex] is also linearly dependent.

We have to find that given statement is true or false.

Dependent vectors:Dependent vectors are those vectors in which atleast one vector is  a linear combination of other given vectors.

Or If we have vectors x_1,x_2,....x_n

Then their linear combination

a_1x_1+a_2x_2+.....+a_nx_n=0

There exist at least one scalar which is not zero.

If v_1,v_2,v_3 are dependent vectors then

a_1v_1+a_2v_2+a_3v_3=0 for scalars a_1,a_2,a_3

Then , by definition of dependent  vectors

There exist a vector which is not equal to zero

If vector v_3 is a linear combination of v_1\;and \;v_2, So at least one of vectors in the set is a linear combination of others and the set is linearly dependent.

Hence, by definition of dependent vectors

{v_1,v_2,v_3,v_4} is linearly dependent.

Option B is true.
