Answer:
-a^2 -a + 12
Step-by-step explanation:
You have to multiply all four together.
-a times a = -a^2
-a times 4 = -4a
3 times a = 3a
3 times 4 = 12
Add them all together =
-a^2 - a + 12
Answer: 
Step-by-step explanation:
According to the given information, we have
n= 40
Critical z-value for 95% confidence = 
Confidence interval :
Hence, the 95 percent confidence interval for this result :
Answer:
Associative property: a + (b + c), a – (b – c) ≠ (a – b) – c, a × (b × c) = (a × b) × c, and a ÷ (b ÷ c) ≠ (a ÷ b) ÷ c
When a = ½ and b = ¾
Now, for checking a × b = b × a, consider LHS and RHS.
LHS = a × b = ½ × ¾ = ⅜
RHS = b × a = ¾ × ½ = ⅜
Thus, LHS = RHS (Hence proved)
Step-by-step explanation:
The number is 717,
You would simply get the answer by looking at all context clues. Hundreds = same as digit in ones, which is 700. Tens = 10. And ones = 7. Therefore, your answer would be 700. Also can be put as 700 + 10 + 7 = 717.
