Answer:
3026
30
Step-by-step explanation: Average sum of the female and male's test score is the sum of expected value of each gender:

Assuming x represents the random male selected and y represents the random female selected:

3026
The average sum of their scores is 3026.
Average difference is the difference between the expected value (mean) of each gender:

1528 - 1498
30
The average difference of their scores is 30.
Answer:
the y-intercept is 22 spaces higher.
Step-by-step explanation:
I don't know, what special operations you want to express with 3(5)x.
as it is written this simply means
3×5×x
no exponents or other special things are visible.
but it should not matter.
whatever is the first function is unchanged the first part of the second function.
so, the only difference is the "+ 22" part.
and that simply means that all y values (the functional result values) are increased by 22.
you know that "f(x) =" has the same meaning as "y =".
and with that also the y-intercept (the y value when x = 0, and therefore the point, where the curve intersects the y-axis) is increased by 22 spaces.
Reflection is the way of projecting a mirror figure to the other side of the axis of symmetry. When reflection is done, like what we can observe in the mirrors, the properties that can be observed are parallelism, colinearity and angle measure. Orientation is not preserved. Answer is C
Step-by-step explanation:
f(x) = y= -x²-x+6
When y is max, f'(x) = 0
f'(x) = -2x-1
Equating to 0,
-2x-1= 0
x= -1/2
Put the value of x in f(x)
y = -(-1/2)² -(-1/2) +6
= -1/4+1/2+6
= 6+1/2
y= 13/2
The answer is false. this is because you have to get the x by itself so you divide both sides by 8.
8x = 0
x = 0
hope this helps, God bless!
