72 ÷ o should be the algebraic expression.
Answer:
y-axis
Step-by-step explanation:
points are (x,y)
since the y-coordinate does not change, but the x-coordinate does, it rotates around the y-axis.
reflection just means it rotates 180 degrees (out of the paper, not around)
This is the graph of a symmetrical normal distribution curve ( a.k.a bell curve). It is perfectly symmetrical with respect to the mean.
<em>So, with respect to which value is the graph symmetrical?</em>
<em>50, as seen in the graph.</em>
So, the mean is 50.
ANSWER: 50
Answer: The value of x and y are 2 and 15 respectively.
Step-by-step explanation:
Since we have given that
Number of hours available in graphics = 21 hours
Number of hours in printing = 19 hours
Number of hours required by x in graphics = 3
Number of hours required by x in printing = 2
Number of hours required by y in graphics = 1
Number of hours required by y in printing = 1
According to question, we get that

Using the graphing method, we get that
x = 2 and y = 15
Hence, the value of x and y are 2 and 15 respectively.
