Answer:
0.48
0.52
No
Yes
Step-by-step explanation:
Result of experiment :
Point up = 48
Point down = 52
Total number of trials = 100
Recall :
Experimental probability = number of outcomes / number of trials
1.)
P(Landing point up) = 48 / 100 = 0.48
2.)
P(Landing point down) = 52 / 100 = 0.52
3.)
The same result will not occur has the outcomes of trials aren't fixed.
4.) Yes, nearly the same result could occur on the second trial, as the number of possible outcubes are just 2 and the number if trials is high.
Answer:
arc AM = 114°
Step-by-step explanation:
the measure of a tangent- chord angle is half the measure of its intercepted arc, that is
∠ MAC =
(AM )
57° =
AM ( multiply both sides by 2 to clear the fraction )
114° = AM
Answer:
Step-by-step explanation:
Be more specific pls?
Answer:
A) 7x + 3y = -8
B) -4x - y = 6 Multiplying B) by 3
B) -12x -3y = 18 then we add A)
A) 7x + 3y = -8
-5x = 10
x = 2
y = -2
Answer is the first one (2, -2)
