We have been given a table of quiz scores whose standard deviation is 5.6. We are asked to find the test scores that are within one standard deviation of the mean.
First of all, we will find the mean of the test scores using average formula.




The scores within one standard deviation would be mean plus one SD and mean minus one SD that is:


Therefore, the quiz scores 17.15 and 28.35 are within one standard deviation of the mean.

Answer:
z = √35
Step-by-step explanation:
In this geometry, all of the right triangles are similar, so corresponding sides are proportional.
long side / hypotenuse = 5/z = z/(2+5)
z² = 5(7) = 35
z = √35
Answer:
168 and 12
Step-by-step explanation:
use fractions for this think of it as 14/15x and 1/15x and x is 180 and solve from there
