The highway safety department wants to study the driving habits of individuals. a sample of 38 cars traveling on a particular stretch of highway revealed an average speed of 70.9 miles per hour with a standard deviation of 7.8 miles per hour. round to 4 decimal places. 1.calculate a 95% confidence interval for the true mean speed of all cars on this particular stretch of highway.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
