Answer:

(a) y = 15 + x

(b) Quiz score will be 65.

Step-by-step explanation:

Line of best fit is the straight line which represents our scatter plot in the best way. This straight line is said to be best if the sum of the distances between the points and the line is small.

Its equation is of the form: y = a + bx , where a is intercept and b is the slope.

(a). The approximate equation of the line of best fit can be: y = 15 + x

Because line meets the y-axis nearly (0, 15).

Also here y represents the quiz score and x represents the time spent in studying.

(b) If y = 15 + x be the equation of best fit then,

Time Spent in Studying(y) = 15 + 50 = 65 minutes.

Since, quiz score(x) = 50 minutes.

Find the volume of this oblique pyramid.
leonid [27]
Cavalieri's Rule tells us that it doesn't matter if the shape is oblique or not, the volume is still found using the regular volume formula.  For a pyramid, this formula is V = 1/3 Bh, with B being the area of the base which is a rectangle.  The area is 10*12 which is 120, and the height is given as 8. So the volume is V = 1/3 * 120 * 8, which is 320 units cubed.
