Answer:
10
Step-by-step explanation:
Yesterday, Priya successfully made 6 free throws.
Today, she made 75% as many as yesterday.
We are asked to calculate the number of successful free throws that Priya made today.
So, the number will be
.
Since it is the number of successful free throws, so it will be 10 throws. ( Answer )
Null hypothesis: 
Alternative hypothesis: 
The null is based on a recent study that 81% of the population (in this case senior citizens) takes at least one medication. The alternative hypothesis is basically the flip of the claim made in the null.
If Amelia wanted to know if the percentage was less than 81%, then the alternative would be p < 0.81
If Amelia wanted to know if the percentage was larger than 81%, then the alternative would be p > 0.81
However, she wants to know if the percentage is 81%.
= 12*5 + 12*3i - 5*2i - 6i^2 (remember that i^2 = -1) so:-
= 60 +26i - 6*(-1)
= 60 + 26i + 6
= 66 + 26i
