What is the value of 3(4(-2)+5x3)-2(7(-2)-3x3)
Answer: 67
Answer:
5
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
u-(5)=0
Step by step solution :
STEP
1
:
Solving a Single Variable Equation:
1.1 Solve : u-5 = 0
Add 5 to both sides of the equation :
u = 5
Answer:
y = - 7
Step-by-step explanation:
Given
8y + 35 = 3y ( subtract 3y from both sides )
5y + 35 = 0 ( subtract 35 from both sides )
5y = - 35 ( divide both sides by 5 )
y = - 7
We know that the interest decreased by 29.3%, therefore
what was left now is simply just 70.7% of the original, therefore we divide
this by 0.707
rate = 7.7% / 0.707
rate = 10.89%
<span>So the rate was 10.89% 10 years ago</span>
Answer:
The random variables in this case are discrete since they have a Multinomial distribution.
The probability mass function for a discrete random variable X is given by:
Where are 
are possible values of X.
The joint probability mass function of two discrete random variables X and Y is defined as
P(x,y) =P(X=x,Y=y).
It follows that, The joint probability mass function of 
is :
