I need help with math if you don't know the answer get out of the question and don't answer it and give the wrong answer or some
velikii [3]

Answer:

Step-by-step explanation:

Frequency table for the height of the seedlings,

Height (in inches)        Number of seedlings

          \frac{1}{2}                                      2              

          \frac{3}{4}                                      4

          \frac{5}{8}                                      2

          \frac{7}{8}                                      2

Now we can draw the line plot as attached.

Average height of the seedlings = \frac{2(\frac{1}{2})+4(\frac{3}{4})+2(\frac{5}{8})+2(\frac{7}{8})}{2+4+2+2}

                                                      = \frac{1+3+1.25+1.75}{10}

                                                      = \frac{7}{10}

The red Maserati traveled at a speed of 120km/h for 5 hours one day. The green Ford Pickup traveled at a speed of 74km/h for 6 h
ehidna [41]

Answer:

156km

Step-by-step explanation:

Given data

The red Maserati traveled at a speed of 120km/h for 5 hours one day.

Distance = speed*time

Distance= 120*5

Distance= 600km

The green Ford Pickup traveled at a speed of 74km/h for 6 hours

Distance = speed*time

Distance= 74*6

Distance= 444km

Hence the difference is

=600-444

=156km
