There are a total of 8 balls
The probability of drawing a white ball is 4/8 on the first draw.
If you replace the ball then the probability will still be 4/8 for a white ball, since these events are independent of each other you multiply 4/8 x 4/8 = 16/64 or 1/4 then the probability of drawing at least 1 red ball with replacement is 1 - 1/4 = 3/4
Now without replacement:
the probability of drawing a white ball is 4/8 since you don't replace the ball then the probability of drawing a white ball the second time is 3/7 again multiply these two probabilities: 4/8 x 3/7 = 12/56 the the probability of drawing at least 1 red ball is 1- 12/56 = 44/56 or 11/14
Well let me tell u this h go destuivut and the. U gotta take the one with the x x 3 fergot the answer is 15
Answer:
The first
Step-by-step explanation:
Answer:
37
Step-by-step explanation:
The angle with a red square is 90, because it's a right angle. 53 + 90 is 143. 180 is the sum of all the angles in a triangle, so you do 180-143. 180-143=37
Answer:
see explanation
Step-by-step explanation:
Differentiate 
using the quotient rule, given
y = 
, then
= 
Here f(x) = 4 - x ⇒ f'(x) = - 1
g(x) = x ⇒ g'(x) = 1 , thus
= 
= 
= - 
-----------------------------------------
Given
y = 3x² + , then
= 6x - ← evaluate for x = 2
= 6(2) - 
= 12 - 1 = 11 ← as required
Let me know if you require assistance on (b) and (c)
