The transportation department of a large city wants to estimate the proportion of residents who would use a system of aerial gondolas to commute to work. the gondolas would be part of the city’s effort to relieve traffic congestion. the department asked a random sample of residents whether they would use the gondolas. the residents could respond with yes, no, or maybe. which of the following is the best description of the method for data collection used by the department? (a) a census (b) a sample survey (c) an experiment with a completely randomized design (d) an experiment with a randomized block design (e) an experiment with a matched-pairs design

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

answer:

c. the third graph

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
