Let the random variable x be normally distributed with mean 55, as shown in the following diagram.
the shaded region between 52 and 55 represents 26% of the distribution.
a) find p(x< 52).
b) find the standard deviation of x.
(for anyone who solves this, work it out in your answer.)

i really don't know sorry but can you me

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
