BRAINLIEST AND 100 POINTS FAST PLEASE A student is assessing the correlation between the number of workers in a factory and the

number of units produced daily. The table shows the data: Number of workers (x) 0 10 20 30 40 50 60 70 80 90 Number of units (y) 2 52 102 152 202 252 302 352 402 452 Part A: Is there any correlation between the number of workers in a factory and the number of units produced daily? Justify your answer. (4 points) Part B: Write a function that best fits the data. (3 points) Part C: What does the slope and y-intercept of the plot indicate? (3 points)

Answer:

see below

Step-by-step explanation:

Number of workers (x) 0 10    20 30   40    50   60   70   80  90

     Number of units (y) 2 52 102 152 202 252 302 352 402 452

Part A

There is a correlation

For each increase of 10 in x, there is an increase of 50 in y

                                      10   10    10   10   10     10   10     10   10

Number of workers (x) 0 10    20 30   40    50   60   70   80  90

     Number of units (y) 2 52 102 152 202 252 302 352 402 452

                                        50  50 50  50   50   50    50   50   50

Part B

m = (y2-y1)/(x2-x1)

   = (452-402) /( 90-80) = 50/10 = 5

The y intercept is the value of y when x =0

The y intercept is 2

The slope intercept form of the the line is

y = mx+b

y = 5x+2

PartC

The y intercept is that we start with 2 of the units and for each worker gained, they will make 5 units per day

If Kamila can do a job in 26 hours and Simon and Kamila working together can do the same job in 9 hours , find how long it takes
Kay [80]

Answer:

Simon takes approximately 13.76 hours to complete the job alone.

Step-by-step explanation:

We are given the following in the question:

Kamila can do a job in 26 hours  

So, part of work done by Kamila in 1 hour =

\dfrac{1}{26}

Simon and Kamila working together can do the same job in 9 hours .

So, (Simon and Kamila)'s 1 hour work =

\dfrac{1}{9}

So, Simon's 1 hour work =

\dfrac{1}{9}-\dfrac{1}{26}=\dfrac{17}{234}

So,

Simon can do \frac{17}{234} part of work in hour = 1

Time taken by Simon to complete the job alone =

\dfrac{1}{\frac{17}{234}}=\dfrac{234}{17}\approx 13.76 \text{ hours}

Thus, Simon takes approximately 13.76 hours to complete the job alone.

Convert the polar equation to rectangular coordinates. (Use variables x and y as needed.)
Alinara [238K]
The standard conversion toolbox:
x=rcos(θ)
y=rsin(θ)

Here r=7csc(θ)
so 
x=7csc(θ)*cos(θ)=7cos(θ)/sin(θ)=7cot(<span>θ)
y=7csc(</span>θ)*sin(θ)=7sin(θ)/sin(<span>θ) = 7
therefore the rectangular coordinates are (7cot(</span><span>θ), 7)</span>

Tres amigos: Andrés, Braulio y Ciro, juegan 3 apuestas
skelet666 [1.2K]

Answer:

La persona que ganó más dinero fue Braulio por S/.16

Step-by-step explanation:

Deje que la cantidad inicial sea Andrés X, Braulio Y y Ciro Z

Luego, dado que cada uno pierde una apuesta en el orden presentado, tenemos;

Después de la primera apuesta, tenemos;

Andrés X-Y-Z, Braulio (Y + Y), Ciro (Z + Z)

En la segunda apuesta, tenemos;

2 (X-Y-Z), 2Y - (X-Y-Z) - 2Z, 2Z + 2Z

2 (X-Y-Z), 3Y - X -Z, 4Z

En el tercero

4 (X-Y-Z), 6Y - 2X - 2Z, 4Z-2 (X-Y-Z) - (3Y - X -Z)

4 (X-Y-Z), 6Y - 2X - 2Z, 7Z - X - Y

4 (X-Y-Z) = 0.48 .............................. (1)

6Y - 2X - 2Z = 0.56 ...................... (2)

7Z - X - Y = 0.28 ............................ (3)

Multiplicamos las ecuaciones (2) por 2 y restamos la ecuación (1), tenemos;

12Y - 4X - 4Z - 4X + 4Y + 4Z = 0.56 * 2 - 0.48 = 0.64

16Y - 8X = 0.64 ...................... (4)

Multiplicamos las ecuaciones (2) por 7/2 y sumamos a la ecuación (3), tenemos;

21Y - 7X - 7Z + 7Z - X - Y = 7/2 * 0.56 + 0.28

20Y - 8X = 2.24 ...................... (5)

Restando la ecuación (4) de la ecuación (5) tenemos;

20Y - 8X - 16Y - 8X = 2.24 - 0.64 =

4Y = 1.6

Y = 1.6 / 4 = 0.4

De la ecuación (5), tenemos;

20Y - 8X = 20 * 0.4 - 8X = 2.24

8X = 8 - 2.24 = 5.76

X = 5,76 / 8 = 0,72

De la ecuación (3), tenemos;

7Z - X - Y = 7Z - 0.72 - 0.4 = 0.28

7Z = 1.4

Z = 1.4 / 7 = 0.2

Por lo tanto tienen inicialmente

X₁ = 0.72

Y₁ = 0.4

Z₁ = 0.2

Después de jugar tienen;

X₂ = 0.48

Y₂ = 0.56

Z₂ = 0.28

Los cambios son

Andrés 0.48 - 0.72 = -0.24

Braulio; 0.56 - 0.4 = 0.16

Ciro 0.28 - 0.2 = 0.08

La persona que ganó más dinero fue Braulio por S/.16
