What type of car is more popular among college students american or foreign? one hundred fifty-nine college students were randomly sampled and asked which type of car they drove. a computer package was used to generate the printout below for the proportion of college students who drive american automobiles.

sample proportion = 0.385667

sample size = 159

upper limit = 0.46424

lower limit = 0.331153

what proportion of the sampled students drive foreign automobiles?

.385667

.614333

.46424

.331153

answer is   .614333

Step-by-step explanation:

Given:

The sample proportion of college students p = 0.385667  

sample size,  n = 159

upper limit  = 0.464240

lower limit  =0.331153

The proportion of the sampled students who drive foreign automobiles: = 1 − 0.385667 = 0.614333

Therefore:  

c)  

0.614333

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
