The regression equation relating high school gpa (x) and college gpa (y) for 100 randomly selected fau students is y = 0.57x + 0.82. use the equation to determine the college gpa of a student whose high school gpa is 2.5. round your answer to two decimal places. (2 points)

a. 3.89
b. 2.62
c. 2.25
d. 1.17

c. 2.25

Step-by-step explanation:

The expression that relates high school GPA (x) to college GPA (y) is:

To find the college GPA of student whose high school GPA is 2.5, simply plug in the value x=2.5 into the expression above:

This student's college GPA is 2.25

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
