Keiko estimated the height of her office building to be 45 ft. The actual height of her office building is 42 ft Find the absolute error and the percent error of Keiko's estimate. If necessary, round your answers to the nearest tenth.

% error formula: | true value minus "your" (as in Keiko's) value | over true value, times 100.

so: 42 - 45 = 3 (it would be negative but we used absolute value, which is how it is supposed to be done. 3 is your absolute error).

3/42 = 0.07143

0.07142 * 100 = 7.142%. she was only 7.142% off from the right answer.

51-50

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
