Using equal intervals of width 2.5 miles/hour, plot a histogram of probability density values (the probability density can be obtained as follows:
take the relative frequency --
# of data values in interval divided by total
# of values – and divide by the interval width)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

52 or what they said ☝️
