We Answer:
84.134% of the scores
Step-by-step explanation:
-This questions needs as to determine the probability of scores less than 282 then find the expectation;
-Let X be the score of a random selection:
The probability of scores below 282 is 0.84134 or 84.134%
Hence, 84.134% of the scores were below 282
I think 45 because if you look at the top of the other 45 the graphs look the same lengths except this one stretches out so 45°
The square root of 150 is 12.2474487139. The square root of 136 is 11.6619037897. And your welcome :)
You know that -3 is the Y intercept(vertical graph line) and then continue 2/1 every x value that is plugged in.
