Each student in a class selected a random sample of 25 marbles from a large jar of red and white marbles and then determined the proportion of red marbles in his or her sample. The proportion in one student’s sample was 0.28. The two people sitting beside that student got sample proportions of 0.36 and 0.24. Of the following, which gives the best explanation for the differences in the sample proportions? *

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
