Answer:
Step-by-step explanation:I
The line in the option C is the best model for the data in the scatter plot. Since in this scatter plot the points above and below the line are equally distributed (i.e. there are 5 points above the line and 5 points below the line) whereas in the rest three graphs the distortion above and below the graph is unequal.
Answer:
x=5,y=5,z=5
Step-by-step explanation:
x=15-y-z
15-y-z-y+z=5
15-2y=5
y=5
x+y+z=15
15-2y+y+z=15
15-10+5+z=15
z=5
x-y+z=5
x-5+5=5
x=5
Answer:
a. No
b. Yes
c. No
Step-by-step explanation:
a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.
b. When you rotate a figure none of the angles in the figure change.
c. For D and D' to have the same coordinates the figure must be rotated by 360.
Answer:
7/√2 cm
Step-by-step explanation:
Area of circle = 77 cm^2
=> π(r)^2 = 77
=> (22/7) x (r)^2 = 77
=> (r)^2 = (77 x 7) / 22
=> (r)^2 = 49/2
=> (r) = 7/√2 cm
Answer:
-11, 723
Step-by-step explanation:
(27+15)/3+8(4+3-10)=-11
(90+30)*6-7*0+(10+5)/5=723
