Probability of spinnin a 2 = 1/8
Probability of rollin a 3 = 1/6
<span>probability of spinning a 2 and rolling a 3 = 1/8 * 1/6 = 1/48
Answer is B
Hope it helps!

This would be 180-62-28=90
So 90 degrees
First factor out that -2
y=-2(x^2-4x+3)
what 2 number muitply to 3 and add to -4
-1 and -3
y=-2(x-3)(x-1)
Answer:
k=4
Step-by-step explanation:
The empirical rule is only applicable on normal distribution while Chebyshev’s theorem is applicable to all type of distribution.
Chebyshev’s theorem states that at least 1-1/k² of data lies within μ±kσ interval.
We have to find the value of k for interval (74,90).
We are given that mean=μ=82 and standard deviation=σ=2
μ-kσ=74
82-k*2=74
82-74=2k
8/2=k
k=4.
Or
μ+kσ=90
82+k*2=90
2k=90-82
2k=8
k=8/2
k=4.
Thus, for k=4 for the interval between 74 and 90 scores.
Answer:
Hello, Have a good day
Step-by-step explanation:
The slope of the perpendicular line is the opposite sign and the inverse of the original line's slope.
(-1,-2) and (0,0).
slope = (0 - -2)/(0 - -1) = 2/1
So ,inverse and opposite would be -1/2
A parallel line has the same slope with a different y intercept
-2 = (-1/2)(-1) + b
-2 = 1/2 + b
b = -5/2
So, same slope, different b (y intercept) for a parallel line.
