Step-by-step explanation:
The question is incomplete. Find the complete question attached
The formula for calculating the distance between two points is expressed by the formula;
d = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinate points (-4, 2) and (4, -4)
d = √(4-(-4))²+(-4-2)²
d = √(4+4)²+(-6)²
d = √(8)²+(-6)²
d = √64+36
d = √100
<em>d = 10</em>
<em>Hence the distance between the points DE is 10units</em>

Answer:
No of white balls = 5
Step-by-step explanation:
Given that,
Total no of red balls = 4
Total no of green balls = 6
The probability of not drawing a white ball in one draw be,
We need to find the number of white balls. Let there are x balls.
The probability of drawing a white ball = 1 - the probability of not drawing a white ball
= 1 -2/3
= 1/3
Using the formula for solving probability of having a white ball.
Hence, there are 5 white balls.
