Answer:
Step-by-step explanation:
error in measurement = 480 - 469 = 11 inches
Percent error = error *100/actual length
= 11 * 100 /480 = 2.9%
There's a quick, easy, sloppy way, and there's a good math way.
Here's the good math way:
If the integers are consecutive, then you can call them 'x', (x+1), and (x+2).
We know what their sum is, so let's add them up:
x + (x+1) + (x+2) = 336
x + x+1 + x+2 = 336
Combine the terms that are alike on the left side:
3x + 3 = 336
Subtract 3 from each side: 3x = 333
Divide each side by 3 : <u> x = 111</u>
The integers are<em> 111, 112, </em>and<em> 113</em> .

Step-by-step explanation:
P(8th grader winning) = 14/42...reduces to 1/3
simulate this by using a number generator with numbers 1 - 6.....with 1 - 3 representing 7th graders, 4 and 5 representing 8th graders, and 6 representing 9th graders
Spread = highest value - lowest.
Its data set C Spread is 5 - 1 = 4
