Answer:
x = 19.5
Step-by-step explanation:
-2x + 7 = -32 (subtract 7 on both sides)
-7 -7
-2x = -39 (Divide by -2)
x = 19.5
Answer: The point slope solution is y+4 = -(1/2)(x-4) which is y + 4 = -(.5)x + 2 or y = -(.5)x -2.
Step-by-step explanation:
The equation of a circle:
(h,k) - the coordinates of the center
r - the radius
The center is (4,0), the length of the radius is 2√3.
Answer:
Let X be the number of times the target is hit. The probability P(X≥1) then equals 1 minus the probability of missing the target three times:
P(X≥1) = 1− (1−P(A)) (1−P(B)) (1−P(C))
= 1−0.4*0.3*0.2
= 0.976
To find the probability P(X≥2) of hitting the target at least twice, you can consider two cases: either two people hit the target and one does not, or all people hit the target. We find:
P(X≥2)=(0.4*0.7*0.8)+(0.6*0.3*0.8)+(0.6*0.7*0.2)+(0.6*0.7*0.8) = 0.788
