Answer:
56
Step-by-step explanation:
The probability both spiners land on red: 0,5*0,6=0,3 (0,5 is A spine lands on red and 0,6 is B spiner lands on red)
The number of both spiners land on red is 84.
So we have:
X——>100%
84——->30%
X=8400/30
X=280
The total number of all spines A and B for onse.
The probability to both spiners land on blue is:
0,5*0,4=0,2 (0,5 is probabiliti to A lands on blue, 0,4 is B lands on blue)
The number of both spiners land on blue is:
280*0,2=56
Skew lines are lines that are not parallel and do not intersect.
BD, AB, FH, EF intersect BF. They are not skew to BF.
DH, CG, AE are parallel to BF. They are not skew to BF.
CD, AC, GH, EG are neither parallel nor do they intersect BF, so they are skew to BF
Answer:
x=-5
Step-by-step explanation:
Vertical lines have the same x value all the time. They are of the form x=
Since it passes through the point (-5,-2) the x value must be -5
x=-5
Answer:
x cannot equal -3, and x cannot equal -2
