Answer:
1/6
Step-by-step explanation:
I think this is tricky.
when you randomly choose the 1st two times, it doesn't matter as long as Na was not chosen, otherwise the probability would become ZERO for the 3rd one be Na.
So, after 1st two is removed, there are only 4 left in the pool, so picking Na at the 3rd draw is 1/4 probability.
But, come to think of it, when 1st draw, you have to draw the other 5 out of 6, 2nd draw the 4 out of 5, then 3rd is 1 Na out of the 4.
So, 5/6 x 4/5 x 1/4 = 1/6
Angle 2=3, so angle 1=4 because angles ABC & BCD equal 90°. When you add together the angles of a triangle you get 180 and if you could put angle 1 and 4 together it would look like an upward version.
That is the best way I could describe it. Hope that helps.
Answer: Ratio of Parts
<u>Step-by-step explanation:</u>
The ratios are equal so the triangles are similar.
Answer:
The expression
1
÷
1/4
is given. Give a real-life application to explain this expression and then simplify it.
Given a life expression to solve this, when one divide 100 pieces of pencil by 25 which is 1/4 of the entire pencil.
1/1/4=1 x 4/1
=4
Step-by-step explanation:
divide 1 by 1 over 4, then using cross multiply
then we have 1 multiply 4 divided by 1
4 is the final answer
Answer:
True: 1, 4, 5
Step-by-step explanation:
Main notations:
A plane is a flat 2D surface with no thickness that extends infinitely far. (Option 1 is true)
A point is an exact location. It has no size, no width, no length, no depth, only position. (Option 2 is false)
Collinear points are two or more points that lie on the same line and have different location. (Option 3 is false)
A line is straight (no bends), has no thickness, and extends in both directions without end (infinitely). (Option 4 is true)
The distance between two points is the length of a line segment that connects them. (Option 5 is true)
