Answer:
B is correct.
Step-by-step explanation:
Quadratic Expression (Standard Form) is:
To say it simply, the expression must have 2 as the highest degree.
This means that if there are any higher or lower degrees than 2 then they are not quadratic expression.
A choice is not quadratic expression because it has 1 as the highest degree.
B choice is correct because 2 is the highest degree.
C choice is wrong because 3 is the highest degree.
D choice is wrong because it is not a polynomial.
Therefore, B is correct.
Answer:
Step-by-step explanation:
Using central Limit Theorem (CLT), The sum of 100 random variables;
is approximately normally distributed with
Y ~ N (100 × 
) = N ( 50, 
)
The approximate probability that it will take this child over 55 seconds to complete spinning can be determined as follows;
N ( 50, )
Using Chebyshev's inequality:
Let assume that X has a symmetric distribution:
Then:
where: (
)
Answer: 5 + j/3
Step-by-step explanation:
Dividing the fare equally
Since they shared the j fare evenly among 3 people, you would divide the j fare by 3 to get j/3
So each person, including Angela, paid j/3 dollars before the tip
Adding the tip
Angela then added 5 dollars to this j/3 so the expression would become 5 + j/3
Final Answer
Angela paid $5 + j/3
Answer:
240
Step-by-step explanation:
Add 3, multiply by 3, and take the positive square root.
3 = (1/3)x²
9 = x²
√9 = 3 = x
The positive solution to the equation is x = 3.
