The percentage error is 23%
Explanation:
The estimated total cost of the groceries = $50
The actual cost of the groceries = $65
To find the error value, we need to subtract the value of actual cost and total cost of the groceries.
Thus,
error value = actual cost - total cost
error value 
Hence, error value = $15
The formula to determine the percent error is given by
Substituting the values in the formula, we get,
Rounding off the value, we have, 23%
Thus, the percentage error is 23%
Answer:
I think it is 123 for number 9 i can't see, the other problems
Step-by-step explanation:
Answer:
Yes it is 5
Step-by-step explanation:
It is 5 because you divide 2 and 10 and it is 5
First account: $6500
Second account: $8500
Set x is amount of money in first account
=> x + 2000 is money in second account.
X*3% + (x+2000)*4% = 535
=> x = (53500 - 8000) / 7
X = 45500 / 7 = 6500
=> account #1 = x = 6500
Acc #2 = x + 2000 = 6500 + 2000 = 8500
Answer:
The measure of angle f is 61°
Step-by-step explanation:
A straight line is 180° meaning;
180 - 98 = 82
82 is the angle measure of the unlabeled angle.
All triangles angles add up to 180° meaning;
37 + 82 = 119
180 - 119 = 61°
