Answer:

To estimate the mean length.

From the table lengths and its corresponding frequency are given

we know that,

The mean formula is defined as the sum of the observations divided by the total number of observations.

The formula to calculate the mean of grouped data. The formula is,

m=\frac{\sum^fx_i}{\sum^f}

we get, Midpoint of the intervals are,

0.95, 2.95, 4.95, 6.95, 8.95, 10.95

Mean is,

=\frac{0.95\times3+2.95\times33+4.95\times62+6.95\times49+8.95\times36+10.95\times7}{3+33+62+49+36+7}

we get,

=\frac{1146.5}{190}=6.034

Answer is: 6.034

Find the amount of time.<br><br> I=$450, P=$2400, r=7.5%
Aliun [14]

~You need to set this problem up in the I=PRT form. This should be your formula then, 450=2400(.075)(t). Then do 2400 times .075 and then times that by t which equals 180t. To get rid of that t then take 450 divided by 180 and you get 2.5. Remember when working with rates put them in decimal form also but your time in years.

I hope this helps you:)
