Answer:

See step by step explanation

Step-by-step explanation:

Costo de la compra si se realiza el martes

Costo total  =  95  +  50  =  140

a) Si la compra es el martes hay un 15 % de descuento en el total, luego entonces:

140 * 0,15  =  21 $ de descuento entonces

el costo real será:

140 - 21  =  119 $

b) Si la compra es el jueves hay un 25 % de descuento, el costo total es el mismo 95  +  50  =  140 $

el descuento es:

140* 0,25  =  35 $

el costo real será:

140 - 35  =  105 $

c) Simplemente el descuento del día jueves es mayor que el del día martes, por alguna razón (que se desconoce el dueño del establecimiento decidió tener mas descuentos el día jueves quizás porque notó que sus ventas eran más bajas ese día)

d) Si cambiaran los precios de los productos la respuesta es la misma porque no han cambiado las condiciones de descuentos, que son las que determinan el precio final

e) Si el lunes la promoción establece que  si compras 3 productos pagas 2  tenemos

Compras 3 * 95 = 285   pero te descuentan 1 te descuentan 95 $

y compras 3 * 50 = 150 pero te descuentan  1 te descuentan 50 $

total descuento  145 $ sobre total de la compra 435

145/435  =  33,33%

Esto quiere decir que el mayor descuento es el día de la promoción el lunes

Abby is registering at a Web site and must select a six-character password.The password can contain either letters or digits.
zaharov [31]

Answer:

a. 2176782336 with repeated characters. 1402410240 with no repeated characters.

b. 7964171460 when all letters can be repeated, but not numbers. 118813760 when only one number and letters can be repeated.

I believe that the password with all letters able to repeat and numbers not being able to is the most secure password, because if someone were to guess the password there is a 1/7964171460 chance of guessing the password.

Step-by-step explanation:

A. Since there are 26 different letters and 10 different numbers, there are 36 characters we can type. If characters can be repeated then, there is 2176782336 different passwords, since on all six number there are 36 possibilities each. So, 36 x 36 x 36 x 36 x 36 x 36 or 36^6 is to evaluated to find the answer. If characters are not to be repeated, there are 1402410240 different passwords, since on the first number there are 36, second has 35, third has 34, fourth has 33, fifth has 32, and sixth has 31. So, 36 x 35 x 34 x 33 x 32 x 31 is to be evaluated to solve this.

B. Since all characters that are letters can be repeated, then there are 26 letters to use forever and 10 numbers you can use with a limit. So, 36 x 35 x 34 x 33 x 32 x 31 which is to be solved if only numbers were to be used, which is 1402410240. Then, you add that with 36 x 35^5 and 36 x 35 x 34^4 and 36 x 35 x 34 x 33^3 and 36 x 35 x 34 x 33 x 32^2. which will be 7964171460. If the password must contain one digit, then you must multiply 10 with 26^5. Since, there is 10 different digits to use for the first number and 26 letters to choose from for the other five. So, it will be 26^5 times 10 which is 118813760.

Use the substitution method to solve the system of equations.
grandymaker [24]
Insert 3x - 7 for y in 15x - 5y = 14
15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
0 = -21
There is no solution.
