We'll need to find and use the LCD here. The LCD is 7(9), or 63. Then this set of fractions becomes
{81/7, 77/7}. The former (first) fraction is the larger one: 81/7 > 77/7, so
9/7 > 11/9.
Answer: 0.0228
Step-by-step explanation:
Given : In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95 with a standard deviation of 10.
i.e. 
Let x denotes the scores.
We assume that the scores are normally distributed.
Then, the proportion of individuals in this population have a score greater than 115 will be :-

Hence , the proportion of individuals in this population have a score greater than 115 = 0.0228
Answer:
c = 6P
Step-by-step explanation:
equation format: c = mP
c = the total cost Donna pays
m = the cost per pound of chocolate(6)
P = the amount of pounds Donna buys
Since we know the cost per pound is $6, we can input it into the equation format:
c = 6P
Now we have an equation that represents the total cost (c) that Donna pays for P pounds.
