Some students in a school were surveyed to determine how many hours they study per night and their grade-point averages. The results are shown in the table. Hours Studying per Night vs. Grade-Point Average Hours studying per night, x Grade-point average, y 0.4 2.0 0.9 2.4 1.5 2.6 2.2 3.1 2.6 3.5 3.3 3.8 If the data are entered into a regression calculator, what is the approximate y-intercept of the resulting regression line? A calculator screen. A 2-column table with 6 rows titled Data. Column 1 is labeled x with entries 0.4, 0.9, 1.5, 2.2, 2.6, 3.3. Column 2 is labeled y with entries 2, 2.4, 2.6, 3.1, 3.5, 3.8. The linear regression equation is y almost-equals 0.628 x + 1.759; r almost-equals 0.994. –1.76 –0.63 0.63 1.76

CAN U PLS JUST POST A PIC OF THE QUESTION THIS IS TOO LONG THANK YO :)

Step-by-step explanation:

answer: i think the answer is etheir c or d but i don't know which one but have a good day!

step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
