The answer to the question is B
Median = middle number
Total ten numbers so
median = (17 + b)/2
given median = 18
so
(17 + b)/ 2 = 18
17+b = 36
b = 36 - 17
b = 19
Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25
Mean = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
Given mean = 17
so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24 +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9
answer
a = 9
b = 19

Completing the square we get: 
and factoring the term we get: 
Step-by-step explanation:
We need to complete the square for the expression 
For completing the square the expression would be of form 
For given expression we have to add (2)^2 and subtract to make it complete the square.
Now, we have to factor the polynomial using formula 
So, 
Completing the square we get:

Answer:
D. decreases the demand for money.
Step-by-step explanation:
Money demand and interest rate has an inverse relationship.
An increase in the interest rate decreases the demand for money. An increase in the price of bonds results in a lower interest rate.
When the interest rate increases, an individual's opportunity cost for holding his money increases. In this condition, the person chooses to hold more bonds, thereby demanding less money.
