Answer: 42</h3>
Explanation:
We have y = -0.9x^2 + 76x - 250 which is in the form y = ax^2+bx+c
where,
The vertex (h,k) is when the profit is maxed out.
h = -b/(2a)
h = -76/(2(-0.9))
h = 42.222 approximately
Let's plug in x values around x = 42
Try x = 41
y = -0.9x^2 + 76x - 250
y = -0.9(41)^2 + 76(41) - 250
y = 1353.10
Now try x = 42
y = -0.9x^2 + 76x - 250
y = -0.9(42)^2 + 76(42) - 250
y = 1354.4
Now try x = 43
y = -0.9x^2 + 76x - 250
y = -0.9(43)^2 + 76(43) - 250
y = 1353.9
We see that the largest profit happens when x = 42.
Answer:
x= 116°
y= 127°
Step-by-step explanation:
x... The angle subtended at the centre is twice the angle subtended at the cicumfernce by the same arch
y.... Angle in a cyclic quadrilateral add up to 180°
hence 180-53=127

Step-by-step explanation:
What is the median of the following data set -1000, -999, 1998, ..., -1, 0, 1, ..., 998, 999, 1000
qwelly [4]
<u>Answer:</u>
The correct answer option is C. 0.
<u>Step-by-step explanation:</u>
We are given the following data set and we are to find its median value:
Median is the middle value of a data set which divides it into to halves.
The data set we have starts from -1000 and goes till 1000 which means there are total 2001 elements in it.
Therefore, 0 will the middle value which is the median for this data set.
