Answer:
"Decreasing the sample size."
Step-by-step explanation:
The margin of error is :
Therefore, as n decreases, margin of error increases.
In the question we are asked " Which action will not reduce the margin of error."
Therefore, the correct option for which action will not reduce the margin of error is "Decreasing the sample size."
Answer:
slope = -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x +
← is in slope- intercept form
with slope m = -
Parallel lines have equal slopes, thus
m = - ← is slope of parallel line
The remaining balances in the first and second account are $5805 and $1020 respectively.
<em><u>Explanation</u></em>
Suppose, the initial balance in the first account was dollar.
As the total amount in two accounts was $9000, so the <u>initial balance in the second account was</u>
He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......
So, <u>the initial balance</u> in the first account was $6450 and in the second account was ($9000 - $6450)= $2550
Thus, the remaining balance in the first account = 90% of $6450 =
and the remaining balance in the second account = 40% of $2550 =
