[When you are dividing or multiplying, the number of significant digits in the answer depends on the part of the question with the least significant digits. For example, There are 2.3 miles left for me to walk. but I can only do 1.54 miles. In the answer I will put two significant digits because the least was 2.3 which has 2 significant digits.]
#1 The answer is 4.821. but since the least # of significant digit is 1.5 which has 2. SO the Ans would be 4.8 mm^2.
#2 Ans is 2.7404 but the correct answer would be 3. because 5 has least value of significant digit. But why is 3? Because the number after 2 is greater than 7.
I hope that helps!
Answer: the mean is -1.0625
Step-by-step explanation:
19x+12y=17
step 1: move the thing that you're looking for to the left side and all the rest to the right side:
(19x +12y)-19x = 17 -19x
12y = 17 -19x
step 2: to find y, you need to get rid of 12. to do so you need to devide everything by that number:
(12y)/12 = 17/12 -19/12 x
y= 17/12 -19/12 x
step 3: simplify of possible. ( in this exercise it isnt)
step 4: rearange the equation if necessary
y= 17/12 + -19/12x
y= -19/12x + 17/12
