Answer: 0.8
Step-by-step explanation:
given data:
uncertainity = 4g
bias = 2g
solution:
σX =0.2 and σY = 0.4
σcX
= 3σX
= 4(0.2)
= 0.8
Answer X = 2
Step-by-step explanation:
-30 + -18 - X + - 24,
+ 30 +30
0 6
-18 -x = -6
DIVIDE
3 -x = -1
BRING THE 3 OVER TO THE NEGATIVE ONE
YOU GET
X = 2
Answer: 1, -4
Step-by-step explanation:
Move all the terms to the left side and set equal to zero. Then set each factor equal to zero. X= 1,-4
-12-(-8)
=-12+8
=-4
Double negative is the same as positive, so the two negatives cancel out to a plus sign.
Answer:
ln18
Step-by-step explanation:
Using the rule of logarithms
loga + logb = logab , then
ln9 + ln2 = ln(9 × 2) = ln18
