Answer:

133/152

Step-by-step explanation:

The probability of 2 independent events is the product of the individual events. Independent means the first event has no effect on the probability of the second event. Since we are replacing the first marble, the first even has no effect on the probability of the second event.

There are 48 total marbles

Let A = pulling a blue marble

Let B = pulling a red marble

P(A) = 14/48

P(B) = 19/48

and

P(A then B) = (14/48)(19/48) = 266/2,304 = 133/1,152

Vector u has its initial Point at (15,22) and it’s terminal point at (5,-4)

Anit [1.1K]

so let's firstly find the component form of "u", keeping in mind that "v" is really in the opposite direction and twice as long, so v = -2u.

$\bf \stackrel{u}{(15,22),(5,-4)}\implies \stackrel{\textit{\underline{u} component form}}{}\implies \stackrel{u}{} \\\\\\ v=-2u\implies v=-2\implies v=$

Answer:

A: 360

Step-by-step explanation:

Split the trapezoid into 2 shapes

Then find the area of the rectangle on the left:

18 × 15 = 270 square yards

Now for the triangle, first find the base by subtracting the 2 parallel lines:

25 - 15 = 10 yards

0.5(10 × 18) = 90 square yards

Add both areas to find total area:

270 + 90 = 360 square yards

All this can be seen in the figure below:
