he owner of a grocery store makes a histogram to show the spread of the weights, rounded to the nearest pound (lb), of all the watermelons in the store. The title of the histogram is, Weight of Watermelons. The horizontal axis is titled, Weight, pounds. From left to right, the axis reads, 0 through 1, 2 through 3, 4 through 5, 6 through 7, 8 through 9, 10 through 11, 12 through 13, 14 through 15, 16 through 17. The vertical axis is titled, Number of Watermelons, and ranges from 0 to 10. Based on the data in the graph, how many watermelons did the grocery store weigh? A $5$ B $8$ C $15$ D $26$

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
