Determine whether the underlined value is a parameter or a statistic. a study of 6076 adults in public rest rooms found that 23% did not wash their hands before exiting. is the value a parameter or a statistic?

a. the value is a parameter because the 6,076 adults in public rest rooms are a sample
b. the value is a parameter because the 6,076 adults in public rest rooms are a population.
c. the value is a statistic because the 6076 adults in public restrooms are a sample
d. the value is a statistic because the 6,076 adults in public rest rooms are a population

C

Step-by-step explaination:

A statistic is a data obtained by sampling a population

A sample is a part of a population studied for the purpose of testing of an hypothesis

6076 is a statistical value because it represents a part (sample) of the whole population

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

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.
