Answer:

<h2>$9441</h2>

Step-by-step explanation:

The interest will be compounded quarterly every year, it means in each year the interest will be calculated 4 times.

In 6 years in total 6 \times4 = 24 times the interest will be calculated.

The yearly interest rate is 4%. Hence, the quaterly interest rate will be \frac{4}{4} = 1%.

Hence, after calculating 24 times, the amount will be turned to 35000 \times (\frac{101}{100} )^{24} = 44440.7127≅  44441.

Hence, the total compound interest is $(44441 - 35000) = $9441

Answer:

The amount of investment after 6 years is $ 44439.5

Step-by-step explanation:

Given as :

The principal amount = p = $ 35,000

The rate of interest = r = 4 % compounded quarterly

The time period of loan amount = t = 6 years

Let The Amount after 6 years = $ A

So,<u> From compounded method</u>

Amount = Principal × (1+\dfrac{\textrm rate}{4\times 100})^{4\times \textrm time}

Or, A = P × (1+\dfrac{\textrm r}{4\times 100})^{4\times \textrm t}

Or, A = $ 35000 × (1+\dfrac{\textrm 4}{4\times 100})^{4\times \textrm 6}

or, A = $ 35000 × (1.01)^{24}

Or, A =  $ 35000 × 1.2697

∴ A = $ 44439.5

So, Amount after 6 years = $ A = $ 44439.5

Hence The amount of investment after 6 years is $ 44439.5  Answer

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally
storchak [24]

Answer:

a) 0.1587

b) 0.0475

c) 0.7938

Step-by-step explanation:

Let's start defining our random variable.

X : ''Thickness (in mm) of ancient prehistoric Native American pot shards discovered in a Hopi village''

X is modeled as a normal random variable.

X ~ N(μ,σ)

Where μ is the mean and σ is the standard deviation.

To calculate all the probabilities, we are going to normalize the random variable X.

We are going to call to the standard normal distribution ''Z''.

[(X - μ) / σ] ≅ Z

We normalize by subtracting the mean to X and then dividing by standard deviation.

We can find the values of probabilities for Z in a standard normal distribution table.

We are going to call Φ(A) to the normal standard cumulative distribution evaluated in a value ''A''

a)

P(X

P(ZΦ(-1) = 0.1587

b)

P(X>7)=P(\frac{X-4.5}{1.5}>\frac{7-4.5}{1.5})

P(Z>1.666)=1-P(Z\leq 1.666)=

1 - Φ(1.666) = 1 - 0.9525 = 0.0475

c)

P(3

P(-1 Φ(1.666) - Φ(-1) = 0.9525 - 0.1587 = 0.7938

Philip ran out of time while taking a multiple-choice test and plans to guess the last 4 questions. Each question has 5 possible
White raven [17]

Using the binomial distribution, it is found that there is a 0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

Considering that there are 4 questions, and each has 5 choices, the parameters are given as follows:

n = 4, p = 1/5 = 0.2.

The probability that he answers exactly 1 question correctly in the last 4 questions is P(X = 1), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{4,1}.(0.2)^{1}.(0.8)^{3} = 0.4096

0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
