Answer: n = 3; n represents a remainder in a division problem.
Explanation:
1) Finding n:
i) Given: 643 = 4 × 160 + n
ii) Do the operations: 643 = 640 + n
iii) Subraction property of the equality: 643 - 640 = n
iv) Do the operations: 3 = n
Answer: n 3
2) Meaning of n
When you divide 643 by 4 the quotient is 160 and the remainder is 3, because 160 × 4 = 640, and 643 - 640 = 3.
This is, 3 is what is left when you split 643 into 4 getting 160 whole parts (plus the remainder, 3).
Answer:
A spinner is divided into three equally sized sections. The spinner is spun three times.
-
independent, since the outcome is not affected by previous spins.
A number cube is rolled twice.
-
independent, since the outcome is not affected by previous rollings.
A bag contains 8 white balls and 3 yellow balls. Two balls are selected from the bag without replacement.
- not independent, since the new outcome depends on the balls that were drawn before.
Step-by-step explanation:
The outcome of an independent variable is not affected by previous outcomes or actions, while the outcome of dependent variables is affected by previous outcomes or actions.
Answer:
The other endpoint of the line segment = (-1, -3)
Step-by-step explanation:
A segment has:
Let (x, y) be the other endpoint of the line segment
Therefore, the other endpoint of the line segment = (-1, -3)
Answer: b = 20 c = 160
Step-by-step explanation:
the value of a straight angle is 180, so 180-20= 160
<span>-12 / 3 x (-8 + (-4)^2 - 6) + 2
= -4</span><span> (-8 + 16 - 6) + 2
= -4(2) + 2
= -8 + 2
= -6</span>
