Observe that as the series progresses, the term decreases by 1/4. To show this, observe the first four terms of the series below.
-200 = (1/4)(-800)
-50 = (1/4)(-200)
-12.5 = (1/4)(-50)
Since we have a common ratio, r, of 1/4, we can use the properties of a geometric series to find the 8th term of the series.
Recall that to find the sum of the nth term of a geometric series, we have
where a is the first term of the series and r is the ratio.
So, for the first eight terms, we have
Therefore, the sum of the 8th series is approximately -1066.65.
Answer: -1066.65
if the equation has a slope of 0, then it's a horizontal line, and in this case, that line is 1 because 1 = 0+B and b=1
the answer is y=1
There are 152 men, 76 women and 38 children.
Step-by-step explanation:
Total persons = 266
Let,
men = m
women = w
children = c
According to given statement;
m+w+c=266 Eqn 1
m = 4c Eqn 2
w = 2c Eqn 3
Putting value of m and w from Eqn 2 and 3 in Eqn 1
Dividing both sides by 7
Putting c=38 in Eqn 2;
Putting c=38 in Eqn 1;
There are 152 men, 76 women and 38 children.
