ryzh [129]3 years ago
8 0

Step-by-step explanation:

If triangles ADB and EDC are similar, then corresponding sides are proportional, from which we conclude:

BC/CD = AE/ED

BC / 21 = 6 / 18

Multiply by 21 on both sides,

BC = 6*21 / 18 = 21 / 3 = 7 units.

(note: Length BC is the same as length CB).

iogann1982 [59]

Answer:

C

Step-by-step explanation:

A modified box plot does not include the outliers in the whiskers, instead they are points outside of the whiskers

5,25,33,34,34,37,37,40,42,45,45,46,46,49,73

This data has 2 outliers 5 and 73 so we have 2 choices for a modified box plot D or D

The lowest value outside of the outliers is 25 , so C would be the logical choice

D has the lower end of the whisker too close to the outlier

How many millimeters are there in 16 meters
Anika [276]
One of the very nice features of the metric system of measurements is that there is a set of standardized prefixes that can be applied to any of the units. Some of the more common ones are
.. micro- . . . one millionth
.. milli- . . . . one thousandth
.. centi- . . . .one hundredth
.. kilo- . . . . .one thousand

Thus, one millimeter is 1/1000 = 0.001 meter. There are 1000 of them in 1 meter, so
.. 16 m = 16000 mm
