Answer:

23% error since 70 more people attended then Marcus counted

Step-by-step explanation:

To calculate the percent error:

  1. We find the difference between the predicted and the actual.
  2. We divide the absolute value of the difference by the actual recorded value.
  3. Convert to a percent by multiplying by 100 and adding a % sign.

Marcus counted 230 and 300 actually came.

1. 230-300=-70 but the absolute value is 70

2. 70/300=0.23

3. 0.23(100)=23%

Marcus' estimated had a 23% error.

Timothy went to a baseball game. after the game, he wanted to ride the bus home. the red line and the blue line buses both stop
marysya [2.9K]

Wonderful!  You gave us everything we could ever possibly want
to know, except the QUESTION.   Fortunately, here at Brainly, we
have five Hogwarts drop-outs who work weekends for us as our
Department of Clairvoyance.  When people post an intriguing
question but leave out some important part of it, our D of C can
usually fill in the missing part for us ... especially on weekends.

The question you left out is:

     What is the next time that a red bus and a blue bus
     will
both leave the stadium together, simultaneously
     and also both
at the same time ?

Since red buses leave every 6 minutes starting at 4:00, and
blue buses leave every 8 minutes starting at 4:00, they both
leave simultaneously and also at the same time at minutes
after 4:00 that are common multiples of 6 and 8.

The least common multiple of 6 and 8 is 24 .  After that,
every multiple of 24 is another common multiple of 6 and 8.
24 minutes is 4 red buses and 3 blue buses ... exactly !

A red bus and a blue bus will leave the stadium together at 4:24 .

After that, it will happen again at 24-minute intervals ... at 4:48,
5:12,  5:36,  6:00, . . . etc.
