I can't understand this after "happening is" but let's do it unaided.

The number of ways to draw a boy first is 6.

Given that, the number of ways to draw a girl next is 10.

That's out of a total of 16 x 15 length two permutations of 16 things

$p = \dfrac{6 \times 10}{16(15)} = 1/4$

Answer: 1/4

Find the coordinates of the point (x,y) at the given angle θ on a circle of radius r centered at the origin. Show all work. Roun

Answer:

(i) The equivalent coordinates in rectangular form are $(x, y) = (-3.277,-2.294)$ .

(ii) The equivalent coordinates in rectangular form are $(x, y) = (0.866, 0.5)$ .

Step-by-step explanation:

In this exercise we must find the equivalent coordinates in rectangular form from polar form. That is:

$(x, y) = (r\cdot \cos \theta, r\cdot \sin \theta)$

Where:

$r$ - Norm of vector, dimensionless.

$\theta$ - Direction of vector with respect to +x semiaxis, measured in sexagesimal degrees.

(i) ( $r = 4$ , $\theta = 215^{\circ}$ )

$(x. y) = (4\cdot \cos 215^{\circ}, 4\cdot \sin 215^{\circ})$

$(x, y) = (-3.277,-2.294)$

The equivalent coordinates in rectangular form are $(x, y) = (-3.277,-2.294)$ .

(ii) ( $r = 1$ , $\theta = 30^{\circ}$ )

$(x. y) = (1\cdot \cos 30^{\circ}, 1\cdot \sin 30^{\circ})$

$(x, y) = (0.866, 0.5)$

The equivalent coordinates in rectangular form are $(x, y) = (0.866, 0.5)$ .

What is the solution to the equation?

adelina 88 [10]

B.
X=5

7(5+9)=7•x+7•9
(7•5)+(7•9)=7x+63
35+63=7x+63

Subtract 63 from both sides and you will be left with
35=7x
Divide each side by 7 (you pretty much just divide 35 by 7)

And x=5
