Answer:
Percent error = 11.6%
Step-by-step explanation:
Given the following data;
Actual height, A = 14.7 m
Estimated height, E = 13 m
a. To find the absolute error;
Absolute error = A - E
Absolute error = 14.7 - 13
Absolute error = 1.7
b. To find the percent error;
Percent error can be defined as a measure of the extent to which an experimental (estimated) value differs from the actual or theoretical value.
Mathematically, it is given by this expression;
Substituting into the equation, we have;
Percent error = 11.57 ≈ 11.6%
43,000 in scientific notation is 4.3 x 10^4
Answer:
- g=games; r=rides
- 1.5g +2.5r = 16.5
- g = 2r
Step-by-step explanation:
Let g and r represent the numbers of games played and rides ridden, respectively. Then the system can be written ...
1.50g +2.50r = 16.50 . . . . . total amount spent
g = 2r . . . . . . . . . . . . . . . . . . relationship of games to rides
24 pounds
In the first two weeks she only lost 2 pounds. In the remaining 11 weeks of her diet she lost 2 pounds a week so 11 x 2 = 22 then add on the 2 pounds lost from the first two weeks 22+2=24.
