12 is the population mean or sample mean of given data.

Given that

The collected data

17, 10, 3, 5, 25

To find

The population mean or sample mean

So, according to the question

we have,

The collected data

 17, 10, 3, 5, 25

For calculate the the population mean or sample mean, We have to find out the total of data, and total number of data.

Total of data = 17+ 10 +3 + 5+ 25

Total of data = 60

Total number of data (n) = 5,

So, we know that

Sample mean = [tex]\frac{total\;of\;data}{n\;number\;of\;data}[/tex]

Now, putting the all values,

We will get,

Sample mean =  60/5  

 = 12          

The Sample mean of given data is 12.

The required measure of the angle m∠B is 121°.

Given that,
Angle A and B are two vertical equal angles.
m∠B = 3x - 17
m∠A = 2x + 29

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
m∠A = m∠B
2x + 29 = 3x - 17
-x = - 46
x = 46

Now,
m∠B = 3  *46 - 17
m∠B =  138 - 17
m∠B = 121°

Answer: 30/4 hours per day

Step-by-step explanation:

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

In this problem we find a system of three linear equations with three variables, which can be resolved by several methods. In this case, we shall use the method of substitution. First, clear the variable x in the third equation:

x = 4 - 3 · y

Second, substitute x in the first two equations:

3 · (4 - 3 · y) + 2 · y - z = 8

12 - 9 · y + 2 · y - z = 8

- 7 · y - z = - 4

2 · (4 - 3 · y) + 2 · z = - 4

8 - 6 · y + 2 · z = - 4

- 6 · y + 2 · z = - 12

Third, clear z in the first equation derived in the previous step:

z = 4 - 7 · y

Fourth, substitute z in the second equation derived in the second step:

- 6 · y + 2 · (4 - 7 · y) = - 12

- 6 · y + 8 - 14 · y = - 12

- 20 · y = - 20

y = 1

Fifth, calculate y and x:

z = 4 - 7 · 1

z = - 3

x = 4 - 3 · 1

x = 1

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

The value of x is 11 units and the length of side RS = 11x-4 is 117 units.

with measurement BC = 60, CD = 50.

Triangle RST : RS = 11x-4, ST = 70

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal.

Given:

BC = 60 and CD = 50

RS = 11x - 4 and ST = 70

Now, considering

BC : CD = RS : ST

60 : 50 = 11x - 4 : 70

60/50 = (11x - 4)/70

50 * (11x - 4) = 70 * 60

11x - 4 = 84

11x = 88

x = 11

So, RS = 11x - 4

RS = 11 x 11 - 4

RS = 117

Hence, the value of x is 11 and the length of side RS is 117

Step-by-step explanation:

The population of a city after 5 years would be 261698.

We know the the formula for the exponential growth of the population is,

P(t) = a(1+r)^t

where, a is the initial population

t is the time period

r is the rate of growth

In this question, we have a = 210000, %R = 4.5

So, r = 0.045

We need to find the population after 5 years.

t = 5

Using above formula,

P = 210000 × ( 1 + 0.045)^5

P =  210,000 × (1.045)^5

P = 210,000 × 1.25

P = 261698.2

P ≈ 261698

Therefore, the population of a city after 5 years would be 261698.

We are told that:

[tex]z(x)= 15x - x^2 + 3[/tex],

and told to find an expression for [tex]z(x - 1)[/tex].

In order to find [tex]z(x - 1)[/tex], we have to replace [tex]x[/tex] in the definition of [tex]z(x)[/tex] with [tex](x-1)[/tex]:

[tex]z(x - 1) = 15(x -1) - (x - 1)^2 + 3[/tex]

Now we can simplify:

⇒ [tex]z(x-1) = 15x - 15 - (x - 1)^2 + 3[/tex]      [Distributing 15 into the first brakets]

⇒ [tex]z(x-1) = 15x - 15 - (x^2 - 2x + 1) + 3[/tex]

⇒ [tex]z(x-1) = 15x - 15 - x^2 + 2x - 1 + 3[/tex]     [Distributing the minus sign]

⇒ [tex]z(x - 1) = 17x - x^2 -13[/tex]          [Combining like terms]

Answer:

B: 3x+(4x+2)=180

Step-by-step explanation:

Supplementary angles are those angles that sum up to 180 degrees. The question gives you the two angles that compose the 180 degree angle thus you get the equation:

Angle 1 + Angle 2 = Supplementary Angle

In this case we see that these two angles are Angles B and C and a supplementary angle is 180 degrees thus:

(4x+2)+3x = 180

Furthermore this also allows you to find x.

The number of coffee product he sells is 38.

He makes $11.50 per hour.

He earns $0.50 for each of these items he sells.

Last week he worked 30 hours and earned $364.

Therefore, the number of coffee product he sells last week can be calculated as follows:

let

x = number of coffee product he sells.

364 = 11.50(30) + 0.50(x)

364 = 345 + 0.50x

364 - 345 = 0.50x

19 = 0.5x

divide both sides by 0.5

x = 19 / 0.5

x = 38

Therefore, the number of coffee product he sells is 38.

They sold 10 bags of butter popcorn, 20 bags of kettle corn and 26 bags of cheddar cheese.

Here, we are given that two boy scouts were selling popcorn for a fundraiser.

Their total revenue = $640

Let the bags of butter popcorn be x

then, the bags of kettle corn sold = 2x

and the bags of cheddar popcorn sold = 2x + 6

Cost of kettle corn = $15/ bag

Cost of butter popcorn = $8/ bag

Cost of cheddar popcorn = $10/ bag

Thus, the total revenue from from kettle corn = $30x

total revenue from from butter popcorn = $8x

total revenue from from cheddar popcorn = $10(2x + 6)x

Thus, we will get the following equation-

30x + 8x + 10(2x + 6) = 640

38x + 20x + 60 = 640

58x + 60 = 640

58x = 580

x = 580/ 58

x = 10

Thus, 2x = 20 and 2x + 6 = 26

Hence, they sold 10 bags of butter popcorn, 20 bags of kettle corn and 26 bags of cheddar cheese.
