Answer:
random variable
Step-by-step explanation:
Random variable also known as stochastic variables are variables that are used in statistics and probability, The value of a random variable must be determined by chance which remain uncertain and depends on the outcome of a random process or experiment.
Unlike algebra, when random variable is introduced into a mathematical model, it is represented by capital letter and it has a single numerical value.
Answer:
19
Step-by-step explanation:
While it's really easy to just divide, I'm sure your teacher wants an equation so:
1615=85x here x= skittle boxes
1615/85=x In this line you can use divide to cancel out the multiplication, giving you
x=19
The answer is 165 because you take 66 and multiply it by .40 and you end up with 165. (.40 because percent means of one hundred so you make 40 to .40 )

Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80
Plug the answer back in
