a) 1 time

b) 1.75%

Step-by-step explanation:

a) The given expression is 1,000(1.0175)^2

Here,

1,000 is the principal (Present Value); (1.0175 = 1 + 0.0175) is the compounding interest rate; and 2 is the number of period (Years).

Since two means 2nd year, therefore, the interest is compounded every year. Hence, it is annual compounding interest.

If the interest rate is compounded annually, the interest will be paid one time each year or period.

b) From part a, if we break the expression,

1,000 is the principal (Present Value); (1.0175 = 1 + 0.0175) is the compounding interest rate; and 2 is the number of period (Years).

Since the interest rate is to be compounded annually, the percentage will not affect.

(1.0175 = 1 + 0.0175) in this expression, one is added to the interest to make the future compounding value.

Therefore, 0.0175 is the interest rate. If we take it to the percentage -

0.0175 x 100 = 1.75%.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
