Interest=percent times rate(in years) times principal.
Or I=PRT
So you invest $580 so I=$580 Rate would be .10 and time would be 1 for one year. So if you put this into the formula you get
$580=P(.65)(1)
So $580=.65P so $580/.65=P so P is approximately $892.31 per year.

lower bound = 90 - 10 = 80 cm

upper bound = 90 + 10 = 100 cm

lower bound d = 1500 x 80 cm = 120,000 cm

upper bound d = 1500 x 100 cm = 150,000 cm

A grocery store chain has been tracking data on the number of shoppers that use coupons. The data shows that 71% of all shoppers
mariarad [96]

Answer: (0.685, 0.735)

Explanation:

First, we will compute the confidence level of the given:

\text{ Confidence Level }=\frac{36}{40}\times100\%=90\%

They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.

The confidence interval would then be:

\begin{gathered} (p-E,p+E) \\ =(0.71-0.025,0.71+0.025) \\ =(0.685,0.735) \end{gathered}

Therefore, the confidence interval would then be (0.685, 0.735)
