Background information: Veteran Betterment has a set of blueprints which show the complete building design layout. The blueprint shows a scale factor of 0.5 inches to 7.5 feet. Please use this scale factor and the information on the blueprint to answer the following questions about the dimensions of the real building.

Look at the picture attached:
What will the height of the building in the real world be?

What will the area of the roof in the real world be?

The square root of 9x plus 7 plus the square rot of 2x equall to 7

Can some one explain this i got sent this. is this a threat i’m scared

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
