<u>Answer:</u>
The correct answer option is b) 
.
<u>Step-by-step explanation:</u>
We are given that the first urn contains 7 white balls and 7 yellow balls and the second urn contains 3 white balls and 6 yellow balls. We are to find the probability that both balls drawn are white.
This means that the first must be white and the second ball must also be white.
P (w, w) = 
× 
=
Therefore, the probability that both the balls drawn are white is 1/6.
Answer:
The perimeter of the shape is 32.5
Step-by-step explanation:
Since the dashed line is not a perimeter,
we add the circumference of the circle plus the 3 sides of the rectangle
The circumference is of the half circle with its diameter being the opposite side of the rectangle
The opposite side is the length 10
So the radius is half of this which is 10/2 = 5
The circumference of the semicircle is thus;
pi * r = 22/7 * 5 = 15.71
full circle is 2 * pi * r
semi is half of full so we divide formula by 2
So let’s add up
15.71 + 10 + 3.4 + 3.4 = 32.51
Answer:
Yes.
(20-(-16)) = 20 + 16
20 + 16 = 36 thus
(20-(-16)) = 36
Step-by-step explanation:
With your equation, I'm pretty sure you are trying to determine whether or not this equation is true. Let's start with the first part.
(20-(-16))
Let's break it down.
20 - -16
Whenever a number is like that, it becomes a positive. (I don't really remember what its called, but it flips in negativity)
20 + 16
20 + 16 = 36.
36 = (20-(-16))
Answer:
Its an irregular pentagon
Step-by-step explanation:
Gradient = 
This means the gradient is 4x.
The y intercept is where the line crosses the y axis. We can see this is at -3.
<h2>
Rule: <u>y = 4x -3</u></h2>
Substitute your values to check if it's right.
y = 4x -3
5 = 4(2) - 3
5 = 8 - 3
5 = 5
1 = 4(1) - 3
1 = 4 - 3
1 = 1
