The shoe store manager borrowed $17,000.00 from the bank to purchase 1000 pairs of shoes. The bank charges a simple interest rat

-Dominant- [34]

Answer:

2550

Step-by-step explanation:

1) So he borrowed 17,000

2) Simple interest is 5%

3) so 0.05 *17000 = 850

4)It takes the manager 3 years so, 850*3=2550

5) so 2550 is the total amount of interest the manager needs to pay

Answer:

A matched-pairs hypothesis test for μD

Step-by-step explanation:

The trainer wants to compare each athlete's time before the program to the time after the program. Since we're comparing times for the same athlete, the data is paired, so we should use a matched-pairs test.

We have k coins. The probability of Heads is the same for each coin and is the realized value q of a random variable Q that is u

nata0808 [166]

Answer:

Step-by-step explanation:

The question is not in correct order ; so the first thing we are required to do is to put them together in the right form to make it easier to proof; having said that. let's get started!.

From the second part " You may find the following integral useful: For any non-negative integers k and m,"

The next equation goes thus : $\int\limits^1_0 \ \ q^k (1-q)^m dq = \frac{k!m!}{(k+m+1)!}$

a. Find the PMF of $T_1$ . (Express your answer in terms of t using standard notation.)

For t=1,2…,

$p_T_1$ (t)= $\frac{1}{(t*(t*1))}$ by using conditional probability to solve PMF

b) Find the least mean squares (LMS) estimate of Q based on the observed value, t, of T1. (Express your answer in terms of t using standard notation.)

By using the mathematical definition of integration to solve the estimate of Q:

$E|Q|T_1=t|= \frac{2}{t+2}$

c) We flip each of the k coins until they result in Heads for the first time. Compute the maximum a posteriori (MAP) estimate q^ of Q given the number of tosses needed, T1=t1,…,Tk=tk, for each coin.

The MAP estimate of q is :

$\bar q = \frac{k}{\sum^k_{i=1}}t_i$
