Jordan spends 50 minutes on his homework.
Step-by-step explanation:
Given,
Time spent on Maths homework = 11 minutes
This represents the 22% time of his total homework.
Let,
x be the total time spent on homework.
22% of x = 11
Dividing both sides by 0.22
Jordan spends 50 minutes on his homework.

Answer:
11 people only ride the bus
Step-by-step explanation:
Let A, B and C represents the event of walking, taking bus and taking a bicycle respectively.
According to the question,
n(A) = 153,
n(B) = 137,
n(C) = 137,
n(A∩B) = 85,
n(A∩C) = 67,
n(B∩C) = 90,
n(A ∩ B ∩ C) = 49,
Hence, the number of people who only ride the bus = n(B) - n(A∩B) - n(B∩C) + n(A ∩ B ∩ C)
= 137 - 85 - 90 + 49
= 11
The value of the derivative at the maximum or minimum for a continuous function must be zero.
<h3>What happens with the derivative at the maximum of minimum?</h3>
So, remember that the derivative at a given value gives the slope of a tangent line to the curve at that point.
Now, also remember that maximums or minimums are points where the behavior of the curve changes (it stops going up and starts going down or things like that).
If you draw the tangent line to these points, you will see that you end with horizontal lines. And the slope of a horizontal line is zero.
So we conclude that the value of the derivative at the maximum or minimum for a continuous function must be zero.

To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -8 ± √((8)^2 - 4(2)(3)) ] / ( 2(2) )
x = [-8 ± √(64 - (24) ) ] / ( 4 )
x = [-8 ± √(40) ] / ( 4)
x = [-8 ± 2*sqrt(10) ] / ( 4 )
x = -2 ± sqrt(10)/2
The answers are -2 + sqrt(10)/2 and -2 - sqrt(10)/2.
