Answer:

Mean: 6.8

Median: 2

Mode: There is no mode of the data set

Step-by-step explanation:

Finding the mean: 5+8+2+9+10= 34 divided by the numbers of the data set which is 5= 6.8

Finding the median: The middle of the data set which is 2

Finding the mode: the most frequently occurring number which doesn't appear in this data set which means there is none.

Answer:

f(6) = 35 × 6 - 175 = 35

Answer:

-15

Step-by-step explanation:

I assume that the question is

[tex]-8-(5/3)x=17\\[/tex]

Then we have

[tex]-(5/3)x=17+8\\[/tex]

Multiply both sides by -(3/5) to get

[tex]x=25\cdot (-3/5)\\x=(25/5)\cdot (-3)\\x=5\cdot (-3)\\x=-15[/tex]

Answer:

x = - 15

Step-by-step explanation:

Given

- 8 - [tex]\frac{5}{3}[/tex] x = 17 ( multiply through by 3 to clear the fraction )

- 24 - 5x = 51 ( add 24 to both sides )

- 5x = 75 ( divide both sides by - 5 )

x = - 15

Answer:

cost of dried fruit per pound=2.5 $/pound

cost of nuts per pound =2 $/pound

total cost=225$ =cost of dried fruit +total cost of nuts

To find the cost of dried fruit we need to multiply cost of dried fruit per pound and the number of bounds hence 2.5 x where x is the number of bounds

which is the total cost of dried fruit and consequently 2y is total cost of nuts where y is the weight of nuts in pound

Step-by-step explanation:

Answer:

Option A.

Step-by-step explanation:

The total cost of the mix is the sum of the cost for dried fruit and nuts.

Recognizing the first term has a coefficient of 2.5, which is the cost of the dried fruit per pound, the term 2.5x represent the total cost of the dried fruit, and x be the number of pound of dried fruit.

Answer:

c = -25

Step-by-step explanation:

1. 23 - 6c = 48 - 5c

(add 5c to both sides)

2. 23 - c = 48

(subtract 23 from both sides)

3. -c = 25

(divide by -1 to both sides)

c = -25

Answer:

a × a × a × a × a × a is the answer

Answer:

The answer would be a × a × a × a × a × a

Step-by-step explanation:

This is because a² is just a × a, and a² to the power of ³ is going to be [tex]a^6[/tex]. And [tex]a^6[/tex] is just a × a × a × a × a × a

Answer:

[tex]w + \frac{5}{6} t - \frac{2}{3} r[/tex]

Step-by-step explanation:

[tex] \frac{2}{3} w + \frac{5}{6} t + \frac{1}{3} w - \frac{2}{3} r[/tex]

[tex] \frac{2}{3} w + \frac{1}{3} w = \frac{2w}{3} + \frac{1}{3} w[/tex]

[tex] \frac{2w}{3} + \frac{w}{3} = \frac{2w + w}{3} [/tex]

[tex] \frac{3w}{3} = w[/tex]

[tex] = w + \frac{5}{6} t - \frac{2}{3} r[/tex]

Answer:

w= 59/5 or 11.8

Step-by-step explanation:

-3(w+4)+8(w-6)=1/2(18-20)

-3w-12+8w-48=9-10

5w-60=-1

5w=-1+60

5w=59

w=59/5

Answer:

Perimeter =177 m

Step-by-step explanation:

area of a rectangle=Length * width

                 [tex]1710m^{2}[/tex] =60*w

                 [tex]1710m^{2}[/tex] =60w

                 [tex]1710m^{2}[/tex] =w

                    28.5m =w

Perimeter of a rectangle=2(length+width)

                                       =2(60+28.5)

                                       =120+57

                                       =177 m
