Hello!
I'll start w/ 18.74 to round. To round 18.74, the 4 wouldn't have any effect raising the 7's value, since anything 4 and below won't increase the number's value. Now you just have 18.7. The 7 will increase the 8's value to a 9, since anything 5 and up will increase the rounded number's value. So 18.74 is now rounded up to 19.
For 41.49, you'll round the 4 to a 5, since 9 will increase the value of the 4. Now you have 41.5. The newly rounded 5 will then increase the 1's value, making it a 2. So now 41.49 is now rounded up to 42.
You can now estimate the sum by adding 19 w/ 42 to get an estimate of 61!
I hope this helps!!!
B (1,0). -2 + 3 = 1. -2 + 2 = 0.
-7 is the answer to this question
Answer:
a. D'(p) = -10p - 6
b. There is a decrease of 96 units of demand for each dollar increase
Step-by-step explanation:
The demand function is:
(a) The derivate of the demand function with respect to price gives us the rate of change of demand:
(b) When p = $9, the rate of change of demand is:
This means that, when p = $9, there is a decrease of 96 units of demand for each dollar increase.
Given:
Item time
shirt 26.1 seconds
sweater 24.3 seconds
pants 32.8 seconds
scarf 18.2 seconds
Add up all the time in seconds:
26.1 + 24.3 + 32.8 + 18.2 = 101.4
divide the sum by the 4 items:
101.4 / 4 = 25.35 seconds
The average time Janette took to fold and put away all 4 items is 25.35 seconds.
