Suppose the line of best fit for some data points has a slope of 1.885. If the
mean of the x-coordinates of the data points is 3.448, and the mean of the y-
coordinates is 12.318, what is the y-intercept of the line to three decimal
places?

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

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:
