A histogram has a horizontal axis labeled from 30 to 70 plus in increments of 10 and a vertical axis labeled “Frequency” from 0 to 10 in increments of 1. Nine vertical bars of class width 5 extend from the horizontal axis and have heights as follows: 30 to 35, 1; 35 to 40, 3; 40 to 45, 3; 45 to 50, 6; 50 to 55, 9; 55 to 60, 8; 60 to 65, 5; 65 to 70, 3; 70 to 72, 2.

i need the table so i can see

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.
