Answer =-0.7x +0
Find the gradient by y2-y1/x2-x1
-14 -7/ 20- -10
-21/30
-0.7
And plug in the coordinates to find the y intercept
7= -0.7 (-10) + c
C=0
Using technology, the linear regression equation by fitting the data in the table is ŷ = 2.4x + 11. The predicted number of hits they will be recorded on day 15 is 47.
Using technology such as a regression calculator or excel ;
The regression equation which models the data is ;
- <em>Slope</em><em> </em><em>=</em><em> </em><em>2.4</em><em> </em><em>;</em><em> </em><em>intercept</em><em> </em><em>=</em><em> </em><em>11</em><em> </em>
<u>The</u><u> </u><u>number</u><u> </u><u>of</u><u> </u><u>hits</u><u> </u><u>recorded</u><u> </u><u>on</u><u> </u><u>day</u><u> </u><u>15</u><u> </u><u>:</u>
<u>Substitute x = 15 into the equation</u> :
ŷ = 2.4(15) + 11
ŷ = 47
Therefore, the predicted number of hits on day 15 is 47 hits.

Answer:
because a triangle has 3 sides and has 3 angles
so each angle on a equilateral triangle has 60 degrees which means
60 x 3 = 180
Step-by-step explanation:
because a triangle has 3 sides and has 3 angles
so each angle on a equilateral triangle has 60 degrees which means
60 x 3 = 180
V=2*pi*r*2*h
V=(4*pi*r)*h
V/(4*pi*r)=h
so h=V/(4*pi*r)
