PLEASE HELP ME! THIS IS DUE AT 5, AND IM RLLY CONFUSED. I NEED TO SHOW WORK AS WELL. I WILL GIVE BRAINLIEST AND 20 POINTS

1. Andrew- 24

  Brandon-  6      

  Carlo- 10

  oh god idk

2. he would have to get 100% because 90+90=180 and 180-80-100 and so 100+80=180 and 180/2=90 so 100%

3. 92.6 because 90+98+96+94+85=463 and 463/5=92.6 and 463+92.6=555.6 and 555.6/6 is 92.6 which is ultimately 92

4. idk understand stem and leaf plots but this is how you find a median

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
