Sammy the Sailor swears entirely too much. The following probability distribution shows the number of times Sammy swears per day

malfutka [58]

Full question attached:

Answer and explanation:

A) B2*B10: cell B2 and B10 have the values regular swear costs and number of swears respectively and we need to multiply these two values to get our answer

B) =IF(B10>10,(B10-10)*B3,0): Sam is supposed to pay an extra $2 for swear words over 10 and so we check if his swear words are above 10 and if they are we find out how many they are by subtracting 10 from them and then we multiply the value gotten by the cost for extra swear words($2)

C) =IF(B10<5,B10*B4,0): here we check if swear words are less than 5 and if they are we multiply number of swears words less than by 5 by the cost ($0.50)

D) F10=C10+D10+E10: to calculate total money in jar(F10), we simply add up regular cost(C10), extra cost(D10) and refund(E10)

Considere la siguiente ecuación: 16a – ( 3a – (6 – 9a) ) = 30a + ( – (3a + 2) – (a + 3) ) III) Al romper paréntesis, agrupar tér

Mamont248 [21]

Answer:

La ecuación simplificada es $a = \frac{11}{19}$ .

Step-by-step explanation:

Tenemos la siguiente ecuación simultánea: $16\cdot a - [3\cdot a - (6-9\cdot a)] = 30\cdot a +[-(3\cdot a+2)-(a+3)]$ . El procedimiento consiste en destruir los paréntesis desde dentro hacia fuera, agrupar los términos semejantes y simplificar. Presentamos el proceso paso por paso:

1) $16\cdot a - [3\cdot a - (6-9\cdot a)] = 30\cdot a +[-(3\cdot a+2)-(a+3)]$ Dado

2) $16\cdot a -\{3\cdot a + (-1)\cdot [6+(-1)\cdot 9\cdot a]\} = 30\cdot a +\{(-1)\cdot (3\cdot a +2)+(-1)\cdot (a+3)\}$ $-b = (-1)\cdot b$

3) $16\cdot a -\{[(-1)\cdot (6)+(-1)\cdot (-1)\cdot 9\cdot a]\}= 30\cdot a +\{\left[(-1)\cdot (3\cdot a) + (-1)\cdot (2)\right] +[(-1)\cdot a +(-1)\cdot (3)] \}$ Propiedad distributiva

4) $16\cdot a -(-6+9\cdot a) = 30\cdot a +(-3\cdot a -2-a-3)$ $-b = (-1)\cdot b$ / $(-b)\cdot (-c) = b\cdot c$

5) $16\cdot a +(-1)\cdot (-6+9\cdot a) = 30\cdot a -4\cdot a-5$ Propiedad distributiva/Definiciones de adición y sustracción/ $-b = (-1)\cdot b$

6) $16\cdot a +[(-1)\cdot (-6)+(-1)\cdot (9\cdot a)] = 26\cdot a -5$ Propiedad distributiva/Definiciones de adición y sustracción/Propiedad modulativa.

7) $16\cdot a +6-9\cdot a = 26\cdot a - 5$ $-b = (-1)\cdot b$ / $(-b)\cdot (-c) = b\cdot c$

8) $7\cdot a +6 = 26\cdot a - 5$ Propiedad distributiva/Definiciones de adición y sustracción.

9) $6+5 = 26\cdot a -7\cdot a$ Compatibilidad con la adición/Definición de sustracción.

10) $11 = 19\cdot a$ Propiedad distributiva/Definiciones de adición y sustracción.

11) $19\cdot a = 11$ Simetría de la igualdad.

12) $a = \frac{11}{19}$ Compatibilidad con la multiplicación/Existencia del inverso multiplicativo/Propiedad modulativa/Definición de división/Resultado.

La ecuación simplificada es $a = \frac{11}{19}$ .

Malika bought 7 new pairs of shoes. Each pair of shoes cost the same amount and was discounted by $21.75.

ikadub [295]

Multiply the amount of the discount by pairs of shoes:

21.75 x 7 = 152.25

Add that to the total she spent:

152.25 + 654.50 = 806.75

Divide the total by pairs of shoes:

806.75/7 = $115.25

The answer is C. $115.25
