Let the vector \mathbf{v}v have an initial point at (1, -2)(1,−2) and a terminal point at (0, 0)(0,0). Plot the vector \mathbf{v

ASHA 777 [7]

Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).

So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, $\vec{v}$ , has been shown in the figure.

The magnitude of the vector:

$|\vec{v}|=\sqrt{(1-0)^2+(-2-0)^2}=\sqrt{1+4}=\sqrt{5}$

The direction of a vector is the angle made by a vector with the positive direction of the x-axis.

From the figure, $\theta = 180 \degree\tan ^{-1} \left|\frac {0-(-2)}{0-1}\right|$

$\theta = 180 ^{\circ} - \tan^{-1}(2) = 180 ^{\circ} - 63.43^{\circ}$

$\theta =116.57 ^{\circ}$

Hence, the required vector having a magnitude $\sqrt {5}$ and direction $116.57 ^{\circ}$ has been shown in the figure.

When playing the lottery game Cash4Life, you must choose a cash ball number from 1 through 4. What is the probability that the r

Butoxors [25]

Answer:

$P(At\ least\ 2) = 0.75$

Step-by-step explanation:

Given

Balls = 1 to 4

Required

Determine the probability of selecting ball numbered at least 2

Here, we'll assume that all numbers have the same probability.

The probability of each ball will be:

$Probability = \frac{1}{4}$

So:

$P(At\ least\ 2) = P(2) + P(3) + P(4)$

Recall that

$Probability = \frac{1}{4}$ --- for each ball

So, the equation becomes

$P(At\ least\ 2) = \frac{1}{4} + \frac{1}{4} + \frac{1}{4}$

$P(At\ least\ 2) = \frac{3}{4}$

$P(At\ least\ 2) = 0.75$
