Step-by-step explanation:
if you don't even understand the question, this is also something you need to tell your teacher. it is his/her job to make you understand it.
a probability is always
desired cases / possible cases
so, if we pick a single student randomly, how many possible options do we have ?
we have 2+5+6+9 = 22 students (as the 4 categories in the table are mutually exclusive).
therefore, our possible cases to pick a student are 22.
now, how many of these 22 students represent our desired cases ?
male, who does not have an A : 9
so, the probability to pick a student who is male and does not have an A is
9/22 = 0.409090909...
Answer:
d y dx=0
Explanation:
From the given
y=sin2x+cos2x
The right side of the equation is
=1
y=1
d y d x=d d x(1)=0
or we can do it this way.
y = sin2x+cos2x
d y d x=2
⋅(sinx)2−1
⋅
d d x(sinx)+2
(cosx)2−1 d d x(cosx)
d y d x=2⋅
sinx⋅cosx+2⋅cosx⋅(−sinx)
dydx=2⋅sinx⋅cosx−2⋅sinx⋅cosx
dydx=0
God bless....I hope the explanation is useful.
Answer:
20°
Step-by-step explanation:
4x+3x+2x=180°(Sum of interior anglevof triangle)
9x=180°
x=20°
