Eric surveys students at his school and finds that 80% have a pet. He wants to estimate the probability that, if he randomly selected 4 students, more than 2 would have a pet. To estimate this probability, he lets the numbers 1, 2, 3, and 4 represent a student who has a pet and 5 represent a student who does not have a pet. He then has a computer randomly select 4 numbers and repeats this 20 times.

The results of these trials are shown in this list.

5533, 2245, 1555, 3341, 4252,5335, 5321, 4155, 2131, 3414,1532, 4251, 2523, 3311, 2352,2332, 5451, 3344, 1121, 5243

Based on this simulation, what is the estimated probability that more than 2 of 4 randomly selected students would have a pet?

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.

inch

step-by-step explanation:

yard and mile are too big.

160 cm

step-by-step explanation:

you have to add all the sides together

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is
