Answer:

P = $ 2,424.27

Step-by-step explanation:

Calculate rate of interest in decimal, solve for r

r = n[(A/P)^(1/nt) - 1]

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

Answer:

\huge \boxed{ \$ \ 2424.27}

Step-by-step explanation:

\sf A=P(1+r)^n \\\\\\ A=final \ amount \\\\ P=principal \ amount  \\\\ r=rate \ (\%) \\\\ n=number \ of \ years

Applying the formula to solve for the principal amount.

\sf 2500=P(1+1.55\%)^2

\sf 2500=P(1.0155)^2

\sf 2500=P(1.03124025)

Dividing both sides by 1.03124025.

\displaystyle \sf \frac{2500}{1.03124025} =\frac{P(1.03124025)}{1.03124025}

\sf P=2424.26534457...

The money to be invested would be $ 2424.27 (to nearest cent).

What is the solution of the system for y-2x=8 and 16+4x2y
Leto [7]

Answer

y = 2x +8

Step-by-step explanation:

Add  2 x  to both sides of the first equation to get:

y = 8 + 2 x


Divide both sides of the second equation by  2  to get:

y = 8 + 2 x


The two equations determine the same conditions on  xy  so this system of equations has an infinite number of solutions, namely all points on the line:

y = 2 x + 8

Without doing any computation, decide which has a higher probability, assuming each sample is from a population that is normally
Nana76 [90]
Answer: The probability in (b) has higher probability than the probability in (a).

Explanation:

Since we're computing for the probability of the sample mean, we consider the z-score and the standard deviation of the sampling distribution. Recall that the standard deviation of the sampling distribution approximately the quotient of the population standard deviation and the square root of the sample size.

So, if the sample size higher, the standard deviation of the sampling distribution is lower. Since the sample size in (b) is higher, the standard deviation of the sampling distribution in (b) is lower. 

Moreover, since the mean of the sampling distribution is the same as the population mean, the lower the standard deviation, the wider the range of z-scores. Because the standard deviation in (b) is lower, it has a wider range of z-scores.

Note that in a normal distribution, if the probability has wider range of z-scores, it has a higher probability. Therefore, the probability in (b) has higher probability than the probability in (a) because it has wider range of z-scores than the probability in (a).
