Answer:
5- 1:1.5
6- 24
Step-by-step explanation:
A.) A = P (1 + r)^t
P = 500 ; r = 3% ; t = 2
A = 500 (1 + 0.03)²
A = 500 (1.03)²
A = 500 * 1.0609 numerical expression
A = 530.45
A numerical expression is an expression that involves purely numbers and one or more operational symbols.
B) compound interest for 2 years.
530.45 - 500 = 30.45 is the compound interest for 2 years.
Answer:
C. -0.34
Step-by-step explanation:
We have that for a normal distribution, the value of z can be calculated using the following formula:
z = (x - m) / sd
where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 16.3, m = 17.4 and sd = 3.2
if we replace we have:
z = (16.3 - 17.4) /3.2
z = -0.3437
if we round to 2 decimal places, it would be -0.34, that is, the answer is C.
