Answer:

v = 7i + 2j

w= - 4i + j

10v = 10(7i + 2j) = 70i + 20j

3w= 3(- 4i + j) = -12i + 3j

10v + 3w

= 70i -12i + 20j +3j

= 58i + 23j

Hope this helps.

5. A box in a supply room contains 15 compact fluorescent lightbulbs, of which 5 are rated 13-watt, 6 are rated 18-watt, and 4 a
skelet666 [1.2K]

Answer:

176/1125 or 0.156

Step-by-step explanation:

There are 15 bulbs, of which 4 are 23-watt. The probability of selecting a 23-watt bulb = 4/15. If we call this probability x, then x = 4/15.

The probability of selecting a 13-watt or 18-watt bulb is the probability of not selecting a 23-watt bulb. If we call this y, y = (6+5)/15 = 11/15. It follows that x and y are mutually exclusive. Here, we have a binomial distribution.

The number of ways of selecting exactly two 23-watt bulbs out of three is

\binom{3}{2} = 3

The probability of selecting them is

3x^2y = 3\times\left(\dfrac{4}{15}\right)^2\times\dfrac{11}{15}=\dfrac{176}{1125}= 0.156
