Your friend has given you a map that he drew of your neighborhood for a class project. before he turns it in, he asks you to check to see how useful it will be. describe what features related to similarity and proportion you will need to look for to determine if the map is useful.
can someone wright it out.

Step-by-step explanation:

A accurate map should be to scale. Scaled distances between features should agree with actual distances. The shapes of objects (eg houses) should be the same as in real life. All road names names and house numbers etc should be displayed.  

However, to create such a map would need considerable expertise. It would be unreasonable to expect someone to produce it for a class project.  

It would be useful if it was roughly to scale with houses shown in approximate positions and shapes. Names and numbers are essential. It would be useful to show North.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
