Answer:

Solution,

For kite adjacent,

Sides are equal

 $6x = 30 \\ or \: x = \frac{30}{6} \\ x = 5$ 

hope this helps...

Good luck on your assignment...

(question 4 only plz)

#4
White block(s) = 2
Red block(s) = 1
Purple block(s) = 3
Total = 2 +1 + 3 = 6 blocks

a) P(white) = $\frac{2}{6} = \frac{1}{3}$
P(red) = $\frac{1}{6}$
P(purple) = $\frac{3}{6} = \frac{1}{2}$

b)Not white block:
1 - $\frac{1}{3}$ OR $\frac{1}{2} + \frac{1}{6}$
$\frac{2}{3}$ $\frac{2}{3}$
Because, when they say no white blocks, we simply do not count them and add the rest to find that probability without white blocks.

c) The probability stays the same: lets say now we have
4 white blocks, 2 red, and 6 purple, total will be 12

P(white)= $\frac{4}{12}$ which is still $\frac{1}{3}$

d) We get two more blocks in the numerator: lets say we have 4 white blocks, 3 red, 5 purple (after adding 2 of each color), total will be 12

P(purple)= $\frac{5}{12}$
(im not quite sure if my explanation here helps you though)

e) 1 more of white and purple, 5 more of red
white = 3, purple = 4, red = 6, total = 12
(you can either add 2 to white or purple but make sure you add 5 of red)

P(red)= $\frac{6}{12}$ = $\frac{1}{2}$

What are the coordinates of the point on the directed line segment from (4, -3)(4,−3) to (9, -8)(9,−8) that partitions the segme

jekas [21]

Answer:

(7, -6)

Step-by-step explanation:

You want to find point X on the segment from A to B such that ...

(X -A)/(B -X) = 3/2

2(X -A) = 3(B -X) . . . . . . cross multiply

2X -2A = 3B -3X . . . . . eliminate parentheses

5X = 2A +3B . . . . . . . . add 3X +2A

X = (2A +3B)/5 . . . . . . . divide by 5

Filling in the given points for A and B, we have ...

X = (2(4, -3) +3(9, -8))/5 = (8+27, -6-24)/5 = (35, -30)/5

X = (7, -6)

The point that divides the segment in the proportions 3:2 is (7, -6).
