Answer:

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

        +12    +12 (add 12 to the 13)

    5x=25  

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64  (first use distributive property)

   8x+24=64

        -24   -24    (then subtract 24 to 64 which is 40)

    8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D

many credit card companies charge a compound interest of 1.8% per month on a credit card balance. Miriam owes 750 on a credit ca
nadya68 [22]

Answer:

Most credit card companies also apply a late payment penalty if you owe a balance and do not make a payment. Ignoring that fee, Miriam's balance will increase as:  

B(n) = 750(1.018)^n  

where B(n) is Miriam's balance after n months. The progression will be:  

$750.00  

$763.50  

$777.24  

$791.23  

$805.48

Let us analyze the following setting. You are given a circle of unit circumference. You pickkpoints on the circle independently
garik1379 [7]

Answer:

We have been given a unit circle which is cut at k different points to produce k different arcs. Now we can see firstly that the sum of lengths of all k arks is equal to the circumference:

\small \sum_{i = 1}^{k} L_i= 2\pi

Now consider the largest arc to have length \small l . And we represent all the other arcs to be some constant times this length.

we get :

 \small \sum_{i = 1}^{k} C_i.l = 2\pi

where C(i) is a constant coefficient obviously between 0 and 1.

\small \sum_{i = 1}^{k} C_i= 2\pi/l

All that I want to say by using this step is that after we choose the largest length (or any length for that matter) the other fractions appear according to the above summation constraint. [This step may even be avoided depending on how much precaution you wanna take when deriving a relation.]

So since there is no bias, and \small l may come out to be any value from [0 , 2π] with equal probability, the expected value is then defined as just the average value of all the samples.

We already know the sum so it is easy to compute the average :

\small L_{Exp} = \frac{2\pi}{k}
