Hi! Where is the rest of this question
1) Formula for the percent of error:
[estimated measure - real measure]
Percent of error = ---------------------------------------------------- x 100
real measure
2) Calculations:
[95 - 91]
Percent error = --------------- x 100 = 4.4 %
91
Answer: 4.4%
Answer: the answer is 3(7+3)
Step-by-step explanation: since 7+3 is in paranthases you add them first to get 10 and you multiply it by the 3 to get 30. We know its correct because 21+9=30.
To find this, use the distance formula. D= square root over... (x2-x1)^2+ (y2-y1)^2. Now plug in your coordinates.
D= square root... (4- -7)^2+ (-5-3)^2. Simplify. 4- -7=11 (two neg= positive) -5 -3= -8. So,
D= square root... 11^2+ -8^2. Simplify. 11^2= 121. And -8^2=64. Now just take the square root after adding. 121+64= 185. And the square root of 185 isn’t a whole number, so your final answer is D= (square root over) 185. Hope this helps
The scale factor is 1.5 because:
9 x 1.5 = 13.5
5 x 1.5 = 7.5
