Answer:
21%
Step-by-step explanation:
Out of the 25 + 9 + 12 + 21 + 12 + 21 = 100 total rolls, 6 came up 21 times so the percentage is 21/100 = 21%.
Answer:
my answer is definitely elementary statistics
Rotate the degrees until the angle is between 0 and 360.
-1035 +360 = -675
-675 + 360 = -315
-315+360 = 45
Now you have sin(45)
The value of sin 45 = √2/2
The value of sin(-1035) is √2/2
Note the equal sign. What you do to one side, you do to the other.
Subtract 3x from both sides, and add 7 to the other
2x (-3x) - 7 (+7) = 3x (-3x) - 24 (+7)
-x = -17
Isolate the x. Divide -1 from both sides
-x/-1 = -17/-1
x = -17/-1
x = 17 is your answer
hope this helps
Answer:
Average Mean = 1.8
Step-by-step explanation:
Missing:
X:0 1 2 3 4 5 6
P(x): 0.20 0.30 0.20 0.15 0.10 0.05
Computation:
Average Mean [Probability distribution]
∑[P(x) × X]
= 0 x 0.20 + 1 x 0.30 + 2 x 0.20 + 3 x 0.15 + 4 x 0.10 + 5 x 0.05
= 1.8
Average Mean = 1.8
