For this case the real step will be given by:
(9.75) * (2.25) * (10) = $ 219,375
Therefore, the best approximation is given by:
(10) * (2) * (10) = $ 200
The difference is:
219,375 - 200 = $ 19,375
Answer:
the best estimate of how many dollars Irina earns each month is:
10 × 10 × 2 = 200
Step-by-step:
1. Identify the coefficients a and b (a=1/2, b=2)
2. Then put those numbers in the vertex formula which is x= -b/2a (-2/2*1/2)
3. Solve for x (x= -2)
4. Find the y-coordinate of the vertex by plugging in x= -2 (y= 1/2(-2)^2+2(-2)- 3)
5. Calculate all of that (y= -5)
6. Put those to coordinates together (Remember: x= -2, y= -5)
7. So your vertex would be (-2, -5)
I hope that made sense ☺️!
Answer:
Explanation:
The table is:
x Given Predicted Residual value
1 -1.6 -1.2 0.4
2 2.2 1.5 0.7
3 4.5 4.7 -0.2
4 6.1 6.7 -0.6
The points on the residual plot must be the pairs (x, residual value). This is:
- (1, 0.4)
- (2, 0.7)
- (3, -0.2)
- (4, -0.6)
Thus, the correct choice is the last one: (4, -0.6)
The answer to this is 493/1000
There are 6 time zones in the US: Hawaiian, Alaskan, Pacific, Mountain, Central, and Eastern. To figure out the time in different zones start with what you know: It's 10 am in the Eastern zone, and LA is in Pacific time. Now go back to the list and count backwards from Eastern to Pacific: 3. For each different time zone subtract 1 from 10: 10-3=7. In LA it would be C. 7 am :)
