Answer: -2.6%
Step-by-step explanation:
Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.
Estimated.number = 15.4 grams.
Actual number = 15.8 grams
Percentage error = (Estimated number - Actual number)/Actual number × 100
= (15.4 - 15.8)/15.8 × 100
= -0.4/15.8 × 100
= 0.0253 × 100
= 2.53
= -2.6% approximately
Answer:
Slope -1/2 y-intercept 1
Step-by-step explanation:
The line crosses through the y-axis at 1
By counting, the line goes down one and over two
The line has a downward slope resulting in a negative slope
Answer: 6
Step-by-step explanation:
This question is pretty confusing in the way that i'm not entirely sure what it wants the answer to be, but i'll do my best.
i used the simple interest formula to come up with the equations, and the formula is I = PRT, (I) being interest, (P) being the amount, (R) being the rate of interest, (T) being the time, in months
b = the balance on the customer's account
c = service charge
t = number of months
if b > 1000, then c = b*.008t
if b </= to 1000, then c = b*.012t
if b < 50, then c = t
if b = 0, then c = 0
it looks really confusing but i'm hoping it's lining up with what you're learning and not completely ?????
i created the restrictions with the inequalities based on the given information of what happens when a balance exceeds 1000, is less than 1000, is less than 50, and is 0.
i used the remainder of the given information in the problem to get the equations -- the interest rate for b > 1000 is 0.8%, which is .008, b </= 1000 is .012, and so on. i hope this wasn't too terribly confusing, and let me know if you have any questions about how i came up with the equations!!
