Answer:
table; occur; tally mark
Step-by-step explanation:
You would use a table to keep track of a distribution of data. You would have to wait for such data to occur. You could use tally marks to keep track to the data.
Hope this helps.
Sorry if it's wrong though.
Answer:
Step-by-step explanation:
Power is defined by work over time. In physics, work can be defined as the energy transferred over from an applied force over some distance. As a formula:
, where F = force applied and d = distance that force is applied over.
*It is worth noting that F must be parallel to the distance travelled. If it is perpendicular, no work is done, and if it is at an angle, find the parallel component and use that for F.
In this case, the force applied must counter the force of gravity on Martha, which is given by 
, where m = Martha's mass and g = gravitational constant 9.8 m/s/s. Therefore, 
. Since she raises her body 4.0 meters, the work done must be 
.
Since power is equal to work over time and t = 2.3 seconds, we have:
(to two significant figures)
Answer:
B
Step-by-step explanation:
The central angle ANC is equal to the arc ABC that subtends it, thus
arc ABC = 138° → B
You take the exponent and move that many places with the number that you get on the opposite side
Sycamore=15.6 recurring
Oak=14.75
Maple=15.75
Birch=15.72
Therefore, A and B are true
