Answer:
Step-by-step explanation:
A'B' is 1/2 times the AB as the scale factor is 1/2.
<u>Find the length of AB using distance formula.</u>
- AB =

<u>And find A'B':</u>
- A'B' = 1/2*2

Correct choice is A

Answer:
5
Step-by-step explanation:
Given that :
Miles ridden in Tuesday = 10
Miles ridden on Wednesday = 20
Sample size, n = 2
Mean :
(10 + 20) / 2
= 30 /2
= 15
Mean absolute deviation :
(|10 - 15| + |20 - 15|) / 2
(5 + 5) / 2
10 / 2
= 5
Answer:
Step-by-step explanation:
-3 = 2x+6y
2x+6y = 0
By transitivity, -3 = 0, a contradiction. No solution.
If you graph the lines, you will see they are parallel, therefore never intersect.
Answer:
The percent error of Heather's calculation is <u>8%</u>.
Step-by-step explanation:
Given:
Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.
Now, to find the percent error of Heather's calculation.
The temperature of coffee Heather measures = 133.4° F.
Coffee's actual temperature = 145° F.
So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:

Now, to get the percent error:



Therefore, the percent error of Heather's calculation is 8%.
