9514 1404 393

Answer:

  d = 3√10 ≈ 9.487

Step-by-step explanation:

The distance formula is appropriate.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((-3 -0)^2 +(2 -(-7))^2) = √(9 +81) = √90

  d = 3√10

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?
Elena L [17]

Answer:

y + 7 = \frac{1}{2} (x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = \frac{1}{2} and (a, b ) = (- 6, - 7 ) , then

y - (- 7) = \frac{1}{2} (x - (- 6) ) , that is

y + 7 = \frac{1}{2} (x + 6)

The length of a text messaging conversation is normally distributed with a mean of 2 minutes and a standard deviation of 0.5 min
Hitman42 [59]
Given:
μ = 2 min, population mean
σ = 0.5 min, population standard deviation

We want to find P(x>3).

Calculate the z-score
 z= (x-μ)/σ = (3-2)/0.5 = 2

From standard tables, obtain
P(x ≤ 3) = P(z ≤ 2) = 0.9772
Therefore
P(x > 3) = P(z > 2) = 1 - 0.9772 = 0.0228

Answer: 0.02275

Maria es una estudiante de la seccion 7-9 que le gusta leer mucho. Actualmente lee un libro que tiene 288 paginas, silee 12 pagi
dmitriy555 [2]

Responder:

24 días

Explicación paso a paso:

Dado que:

Total de páginas = 288

Número de páginas leídas por día = 12

Número de días que se necesitarán para leer el libro completo:

Total de páginas / número de páginas leídas por día

288/12

= 24

Por lo tanto, a María le tomará 24 días leer el libro completo, si lee 12 páginas del libro por día.
