<span>Present value = Future value / [1+ {Interest rate}]^n where n is the duration of investment.----------(1)
Given : Interest rate = 3%, Duration, n = 3 years.
Plugging in the values in the above equation (1)
Present value = (4370.91) / (1+3%)^3
Present value = 4370.91/(1.03^3)
Present value = 4370.91/1.0927
Present value = $ 4000.</span>
The answer is 12 and 5
12+5=17
12X5=60
Hope that helps!
Answer:
B
Step-by-step explanation:
Just factor it:
5(42 - 12) = 5(30)
Here we are given the equation :
In order to solve for t, we have to isolate t on the left side.
here t is in multiplication with 4, so we apply opposite operation of multiplication on both sides.
opposite operation of multiplication is division.
so dividing both sides by 4 we have:
so we have t=17
Checking:
We can check if our answer is correct or not.
plugging value of t on left side of equation
LHS: 4t =4*17 =68
RHS:=68
since LHS=RHS
So our answer t=17 is correct .
Answer: t=17
A critical value is the point on the scale of the
test statistic (z test in this case) outside which we reject the null
hypothesis, and is taken from the level of significance of the test. The critical
values can be obtained from the standard distribution tables for z and for this
case, it is equivalent to:
critical value zα/2 at 98% confidence level = 2.326
Answer: 2.326
