Answer:
Jennifer just received the results of her SAT exam.
Her SAT Mathematics score of 600 is in the 78th percentile.
It means there is 78% of test-takers has score equal or less than hers (or 22% of test-takers has score greater than hers)
Hope this helps!

MPC stands for "marginal propensity to consume," which refers to a rise in consumer spending for every unit of income level achieved.
Marginal propensity to save (MPS) is the percentage of a person's income that they put away for savings for every unit that their income level rises.
Spending multiplier = Increase in income level for each unit increase in autonomous spending = 1/(1-MPC) = 1/MPS Spending multiplier = Increase in income level for each unit increase in autonomous expenditure. This is further explained below.
<h3>What is a multiplier?</h3>
Generally, the amount by which the return on investment is greater than the investment itself is referred to as the investment's return on investment (ROI).
In conclusion, Marginal propensity to save (MPS) is the percentage of a person's income that they put away for savings for every unit that their income level rises.

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃
<h3>Activity Series</h3>
From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.
Let us look at each of the given options;
A) Ag + FeCl₃
From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.
B) Zn + CaO
Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.
C) Ba + Na₂CO₃
Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.
D) Cr + KNO₃
Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.
Complete question is;
Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
A. Ag + FeCl₃
B. Zn + CaO
C. Ba + Na₂CO₃
D. Cr + KNO₃

Answer
-60
Explanation
-4 times -5 times -3 is equal to -60, and the negatives don't cancel out because it's an odd number.
