A television network wanted to estimate the proportion of a one-hour time slot that is made up of commercials. The network took random samples of 10 one-hour time slots. The following are the sample proportions the network found
in 12 samples
0.25 0.3 0.2
0.25
0.3
0.35 0.25 0.3
0.25 0.35 0.3
0.3
Part A
What is the estimated proportion of commercials in all one-hour time slots? Round your answer to the nearest
thousandth.
The estimated proportion of commercials in all one-hour time slots is
Part B

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

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.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
