Teachers at price middle school are planning a birthday party for the principal planners estimated that 42 slices of cake would be needed. in fact only 30 slices of cake were eating what was the error in estimate of how mucj cake was eaten ?

E = 12

RE = 0.4

Step-by-step explanation:

The estimation error (E) is defined as the absolute value of the difference between the actual value (RV) and the estimated value (EV). With RV = 30 and EV = 42.

E = | EV - RV | = | 42 - 32 | = | 12 | = 12

A complementary concept could be the relative error (RE), which is defined as the ratio between the absolute error and the actual value.

RE = E / RV = 12/30 = 2/5 = 0.4

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
