Shira's math test included a survey question asking how many hours students spent studying for the test. The scatter plot below shows the relationship between how many hours students spent studying and their score on the test. A line was fit to the data to model the relationship. Which of these linear equations best describes the given model? Choose 1 Choose 1 (Choice A) A \hat y=x+45 y ^ =x+45y, with, hat, on top, equals, x, plus, 45 (Choice B) B \hat y=10x+45 y ^ =10x+45y, with, hat, on top, equals, 10, x, plus, 45 (Choice C) C \hat y=-10x+45 y ^ =−10x+45y, with, hat, on top, equals, minus, 10, x, plus, 45 Based on this equation, estimate the score for a student that spent 555 hours studying.

step-by-step explanation:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
