Answer:
Only the given table represents a function. Option 1 is correct.
Step-by-step explanation:
A relation is called a function, if there exist a unique value of y for each value of x. It means for each input there exist a unique output.
A function is always a relation but all relations are not function.
In the given table for each value of x, we have unique value of y, therefore the given table represents a function.
In second relation, at x=-2, the values of y are y=10 and y=-7. For single x, there are more than one value of y, therefore the second relation is not a function.
In third relation, at x=6, the values of y are y=-2 and y=1. For single x, there are more than one value of y, therefore the third relation is not a function.
Answer:
0.714 mins
Step-by-step explanation:
by using the rule of three:
180 mins----->252 ballons
x----------------1 ballon=0.714 mins
the answer is:
A. slope: 9, y-intercept: -6
15. 1/2 base * <span>hight ,</span> 1/2 * 11 * 6 = the answer is 33 cm^2
16. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. So the answer is 155.
17. <span>The mean is the usual average, so I'll add and then divide. (33+25+42+25+31+37+46+29+38) / 9 = 34
18. You have to draw a plot.</span>
