It is a rational.
Step-by-step explanation:
0.25² = 0.0625
It is a rational.
Answer:
It simply is the product between 8 and 1.8 so 14.4, as anything added to himself n times is equal to the product between the number and n.
In fractions:
1.8 = 18/10 = 9/5
8·(9/5) = 72/5
Answer:
0.65
Step-by-step explanation:
When we have a finite number of events
with its corresponding probabilities
with
then the expected value of the distribution is given by
In our case, we have
with probabilities
So, the expected value is
E = 0*0.58+1*0.24+2*0.13+3*0.05 = 0.65
Given:
y varies directly with x
y = 8 when x = -6
what is the value of y when x = -2?
y = kx
we need to get the constant of variation.
8 = k(-6)
8/-6 = k
4/-3 = k or - 1 1/3
y = -4/3 (-2)
y = (-4*-2) / 3
y = 8 / 3
y = 2 2/3 OR 2.67
The correct answer is Choice B. y = -1.33x ; 2.67
