Sandy is baking biscuits. Each biscuit is 6.7cm in diameter and about 0.5cm thick.
Calculate the radius of the biscuit and show
your workings:
Sandy wants to fit as many biscuits as
possible on a rectangular baking tray
measuring 33cm long and 22cm wide.
Sandy thinks she will be able to fit 14
biscuits on the tray. Is she correct?
How many biscuits will fit on the tray? Show

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

a - base

b - exponent

so,

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
