Answer:
SUBTRACT
Step-by-step explanation:
Their payment can be computed using the formula for amortization.
... A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . . where ...
... ... P is the principal amount of the loan, r is the annual rate, t is the number of years, A is the monthly payment.
Filling in your values, this becomes ...
... A = 150,000·(0.055/12)/(1 -(1 +.055/12)^(-360))
... A ≈ 851.68
Their monthly payment is $851.68.

Answer:
Q1 value is 3.0625 inches
Step-by-step explanation:
Q1 is the 25th percentile, that is
P(z<z*)=0.25 where z* is the z-score of the 25th percentile.
Corresponding z* is -0.675.
z* can also be calculated using the equation
z= where
- X is the 25th percentile(Q1) value
- M is the mean rainfall in January in the city (3.4 inches)
- s is the standard deviation (0.5 inches)
Solving the equation for X, we have X=-0.675×0.5+3.4 =3.0625 inches
