9514 1404 393

Answer:

  (b)  48

Step-by-step explanation:

In this geometry, the altitude (x) is the root of the product of the segments of the hypotenuse.

  x = √(36·64) = √36×√64 = 6×8

  x = 48

_____

All of the triangles are similar, so the ratios of corresponding sides are the same.

  short side/long side =  x/64 = 36/x

  x^2 = (64)(36) . . . .  as above

What is the equation in point-slope form of a line that passes through the points (7, −8) and (−4, 6) ?
Aleks04 [339]
First you differentiate to find the gradient

dy/dx = (6 - - 8) / (-4 - 7)
          = 14 / -11
          = - 14/11

Then you use this formula
y - y1 = m (x - x1)

y1 being the y coordinate
x1 being the x coordinate
m being the gradient (or slope)

y - 6 = -14/11 (x - - 4)
y - 6 = -14/11x - 56/11
y = -14/11x + 10/11

The set of life spans of an appliance is normally distributed with a mean
HACTEHA [7]

Answer:

24 months

Step-by-step explanation:

Lifespan with z-score of -3 in the the set of normally distributed life spans of an appliance can be calculated using the equation:

z=\frac{X-M}{s} where

  • X  is the lifespan we are looking for
  • M is the mean life span of the appliance (48 months)
  • s is the standard deviation of the distribution of the life spans (8 months)

We have -3=\frac{X-48}{8}  that is

-24=X-48 and

X=24 months.

The life span of an appliance that has a z-score of -3 is 24 months.
