Answer:
A
Step-by-step explanation:
We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
So the answer is 1
That means, that 68% is the answer.
Let n = the unknown number
"The product of a number and 4" = 4 * n = 4n
"increased by 16" = + 16
Set it all equal to - 2.
4n + 16 = - 2
Subtract 16 from both sides to get constants on one side and variables on the other.
4n = - 2 - 16
Combine like terms:
4n = - 18
Divide both sides by 4 to isolate variable n.
n = - 18 / 4
= - 4 and 2/4 = - 4 and 1/2
Answer:
number 2
Step-by-step explanation:
Put the whole problem, we need more information
[n] + [n+2] + [n+4] = -198
3n +6 = -198
3n = -198 -6 = -204
n = -204/3 = -68
1st even integer = -68
2nd even integer= n+2 = -68 + 2= -66
3rd even integer= n+4 = -68 + 4 = -64
