CAC can be changed into CAAC. This is because the first rule says that any letter can change into an A so
 CAC=CAA
The last condition says that when you double , you have to double all letters,
Since A has been doubled,C needs to be doubled too.So:
CAA=CAAC

At a theater, the price of 4 adult
olga_2 [115]

Answer:

The price of adult tickets =  $27

The price of child tickets = $16

Step-by-step explanation:

The price of adult tickets = x

The price of child tickets = y

4x +3y = 156           ---------------------> equ 1

3x + 4y = 145           ---------------------> equ 2

multiply  equ 1  by 3 ===>    12x + 9y  = 468

multiply  equ 1  by 4 ===>    <u>12x + 16y  = 580</u>

subtract ,                                      -7y = -112

                                                        y = -112/-7

                                                        y = 16  

Substitute y value in equ 1,

                  4x + 3*16 = 156

                     4x + 48 = 156

                              4x = 156 - 48

                               4x = 108

                                 x = 108/4

                                  x = 27

The price of adult tickets =  $27

The price of child tickets = $16

A sport statistician gathered data on the number of points scored in each game by high school basketball players across the coun
Sonbull [250]

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98

<h3>What is a sample size?</h3>

The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.

Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.

For a population mean of 20.15 and a standard deviation of 3.7

68% are within μ ± σ/√n,

hence,

68% = 20.15 ± 3.7/√20 = (19.32, 20.98)

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.

Help please !! :(

The annual interest rate is 20.4% which is a 20.4/12 = 1.7% monthly rate.

1.7% = 0.017

-------------------------------------------------

Month 1:

interest = 0.017*(current balance)

interest = 0.017*(1045.87)

interest = 17.77979

interest = 17.78

---------

principal = payment - interest

principal = 490 - 17.78

principal = 472.22

---------

new balance = (old balance) - principal

new balance = (1045.87) - 472.22

new balance = 573.65

at the end of month 1, the balance is $573.65

So far, you have paid $490

-------------------------------------------------

Month 2:

interest = 0.017*(current balance)

interest = 0.017*(573.65)

interest = 9.75205

interest = 9.75

---------

principal = payment - interest

principal = 490 - 9.75

principal = 480.25

---------

new balance = (old balance) - principal

new balance = (573.65) - 480.25

new balance = 93.40

At the end of month 2, the balance is $93.40

So far, you have paid 490+490 = 980 dollars

-------------------------------------------------

Month 3:

The current balance of $93.40 is less than $490, so we don't have to pay the full $490. We can simply pay off the remaining balance. 

Add this to the current total paid amount so far to get 980+93.40 = 1,073.40

I'm not sure if I made a rounding error somewhere or if there is a typo. The closest answer choice I see is choice B. So I'm thinking the answer is choice B. I'd get a second opinion or ask the teacher on this one.
