Answer:
The percent increase in iron = 50 %
Step-by-step explanation:
Initial amount of iron per serving = 1.2 mg
After an increase the amount of iron per serving = 1.8 mg
Increase in the amount of iron per serving = 1.8 - 1.2 = 0.6 mg
Percent increase in iron is calculated as
Put the values in above formula we get
= 50 %
Therefore the percent increase in iron = 50 %
What is the rest of the question?
Answer:
D. The mean for the 8th grade players is 3 times the mean for the 6th grade players. & E. The data set distribution for the 8th grade players is symmetric.
The first thing you should know is that the slope of the line that passes through two points, by definition is given by:
m = (y2-y1) / (x2-x1)
Substituting the values we have:
m = (76-70) / (28-30)
m = -3
answer:
the slope of the line between points a and b is
m = -3
