If a set of vectors is linearly dependent, then that means at least one vector can be expressed as a linear combination of the rest.

If the set of vectors is linearly independent, then multiplying the set by a scalar can't make them dependent.

Rachel has a bag containing 3 red marbles, 5 purple marbles, and 10 blue marbles.
tankabanditka [31]

Answer:

5/18, 13/18

Step-by-step explanation:

The basic probability of anything is Specific Outcome / Total Outcomes

The specific outcome here is pulling a purple marble. We see there are 5 purple marbles therefore there are 5 ways to get them. The total outcomes are the total number of marbles which is 18. Therefore, the answer is 5/18

The complement of a probability is 1 minus the original probability, so, it would be 1 - 5/18 here getting us 13/18 as the answer.

Cindy has a picture that is 3 inches wide and 4 inches long. She wants to enlarge it so that it is 12 inches long. How wide will
motikmotik

Answer:

9 inches wide

Step-by-step explanation:

What we know:

Cindy has a 3-inch by 4-inch picture.

She wants to enlarge that picture so the length is 12 inches.

It's 4 inches long in the original, and 12 inches in the scale.

Divide 12 by 4 to get a scale factor of 3.

Multiply 3 by 3 (essentially 3^2) to get 9 inches as the width.

-6a÷[3(1-1/2a)-(2/3-3a)-a] a=-1
e-lub [12.9K]

Step-by-step explanation:

\frac{ - 6a}{(3(1 -  \frac{1}{2} a) - ( \frac{2}{3}  - 3a) - a)a } =  - 1 \\  \frac{ - 6a}{( \frac{3}{2} a  +  \frac{7}{3}a - a)a }  =  - 1 \\  \frac{6a}{ \frac{17}{6} a {}^{2} }  =  1 \\ 6 =  \frac{17}{6} a \\ a =  \frac{(6 \times 6)}{17}  \\ a =  \frac{36}{17}
