<span>So we want to know how long will the scale drowing of the building be if the building is 265.25m long and the scale is 1 inch on the drawing is equal to 25 meters of the building. To find the answer lets scale the building. If the real length of the building is 256.25 meters, then the number of inches will be: 256.25/25=10.25 inches. </span>

What is the value of y in the relative frequency table? Round the answer to the nearest percent.
Ulleksa [173]
Given a relative frequency table is made from data in a frequency table.

Frequency Table
               G                    H              Total
E            12                   11                23

F            14                    8                 22

Total       26                   19                45

Recall that the relative frequency table is obtained from the Frequency table by dividing each entry of the frequency table by the ovarall total of the frequency table.

Thus the relative frequency table of the frequency table above is given by:

Relative Frequency Table
                        G                                       H                                  Total
E         12/45 = 0.27 = 27%          11/45 = 0.24 = 24%       23/45 = 0.51 = 51%

F         14/45 = 0.31 = 31%          8/45 = 0.18 = 18%        22/45 = 0.49 = 49%

Total    26/45 = 0.58 = 58%         19/45 = 0.42 = 42%      45/45 = 1.00 = 100%

For the given relative frequency table with the missing value y being the value of the relative frequency of E and G.

Therefore, the value of y is 27%

Ujalakhan01 please help! What's (x+1)(x-1)?
Natasha2012 [34]

Answer:

x^2-2x+1

Step-by-step explanation:

We can solve this by using FOIL

First, Outside, Inside, Last

Multiply the x with the x to get x^2

Then x times -1 for the outside numbers to get -x

Then -1 times x for the inside numbers to get -x

And finally -1 and -1 for the last numbers to get 1

Add the two -x to get -2x.

Put it all together

x^2-2x+1
