Answer:
Option B. 8.6%
Step-by-step explanation:
Simple index of two stocks: i=?
i=[(5,000*5.1+2,500*7.45)/(5,000*4.5+2,500*7.25)-1]*100%
i=[(25,500+18,625)/(22,500+18,125)-1]*100%
i=[(44,125)/(40,625)-1]*100%
i=[1.086153846-1]*100%
i=[0.086153846]*100%
i=8.6153846%
i=8.6%
X= 2i(square root of 6), -2i(square root of 6)
36 i guess ha please that not right
Answer: Median= 91; 8th quiz score=86
Step-by-step explanation: The sum of the scores is 8×92=736. Subtract the 6 given scores and then a 100 for the seventh quiz to find the score she got on the 8th quiz, this is an 86. Now that you have all the scores, arrange them all in the least to greatest order and find the average of the middle two numbers (median), which is 91!
