Answer:

The slope of the linear function would be 2.

Step-by-step explanation:

We are given the points

(–2, –8) and (1, –2)

Our formula would be:

m = rise / run = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }

So, plug in these values to the slope formula to find the slope

= \frac{-2 - (-8)}{1-(-2)}

= \frac{6}{3}

= 2

I hope this helps!

A sector of a circle of 7cm has an area of 44cm².calculate the angle of the sector,correct to the nearest degree π =22\7​
Hitman42 [59]

Answer:

\theta=102.85^{\circ}

Step-by-step explanation:

Given that,

The radius of circle, r = 7 cm

The area of sector, A = 44cm²

We need to find the angle of the sector. The formula for the area of sector is given by :

A=\dfrac{\theta}{360}\pi r^2

Solve for \theta.

\theta=\dfrac{360A}{\pi r^2}\\\\\theta=\dfrac{360\times 44}{\dfrac{22}{7}\times 7^2}\\\\\theta=102.85^{\circ}

So, the angle of the sector is equal to 102.85^{\circ}.

Answer:

SA = 1099 square inches.

Step-by-step explanation:

Just plug into the formula

SA = 2pir^2 + 2pi r h where pi = 3.14, r = 5 and h = 30

SA = 2 (3.14) (5^2) + 2 (3.14)(5)(30)

SA = 157 + 942

SA = 1099 square inches.

Si elegimos un día de la semana al azar, ¿qué probabilidad hay de que sea fin de semana (ya sabemos que hay dos días…)?
irga5000 [103]

Answer:

La probabilidad que hay de que sea fin de semana es \frac{2}{7}

Step-by-step explanation:

La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.

P(A)=\frac{numero de casos favorables}{numero de casos posibles}

En este caso:

  • número de casos favorables: 2 (cantidad de días del fin de semana)
  • número de casos posibles: 7 (cantidad de días totales en la semana)

Reemplazando:

P(A)= \frac{2}{7}

<u><em>La probabilidad que hay de que sea fin de semana es </em></u>\frac{2}{7}<u><em></em></u>
