1,030 at 4% compounded semiannually for 2 years

Mathematics
1 answer:
kotegsom [21]2 years ago

Answer: $1114.91

Step-by-step explanation:

The formula for compound interest is

A= P(1+\frac{r}{n})^{nt}  \\

Where

A = final amount

P = initial principal balance (1030 for this)

r = interest rate (0.04 for this)

n = number of times interest applied per time period (2 for this)

t = number of time periods elapsed (2 for this)

A= 1030(1+\frac{.04}{2})^{(2)(2)}  \\\\A= 1030(1+0.02)^{4} \\A=1030(1.02)^4\\A=1114.905125

This rounds up to $1114.91

The distribution of scores on a recent test closely followed a Normal Distribution with a mean of 22 points and a standard devia
maksim [4K]

6.68% of the students scored at least 19 points on this test while the 85 percentile has a test score of 24.08 points

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean.\sigma=standard\ deviation, x=raw\ score\\\\Given\ that\ mean(\mu)=22,standard \ deviation (\sigma)=2\\\\For\ x>19:\\\\z=\frac{22-19}{2}=1.5

P(x > 19) = P(z > 1.5) = 1 - P(z < 1.5) = 1 - 0.9332 = 0.0668

6.68% of the students scored at least 19 points on this test

b) 85 percentile corresponds to a z score of 1.04

z=\frac{x-\mu}{\sigma}\\\\1.04 =\frac{x-22}{2} \\\\2.08=x-22\\\\x=24.08

The 85 percentile has a test score of 24.08

Find the derivative of f(x) = negative 9 divided by x at x = -4. (6 points) 4 divided by 9 16 divided by 9 9 divided by 16 9 div
Len [333]

Answer:

9/16

Step-by-step explanation:

f(x)=-\frac{9}{x}

f(x)=-9x^{-1}

Derivative rule:

f(x)=x^{n} \\

\frac{df}{dx}=nx^{n-1}

Here, n=-1, so

\frac{df}{dx}=(-9)(-1)x^{-2} =\frac{9}{x^{2} }

Evaluating this at x=-4 gives 9/16
