Answer:
Step-by-step explanation:
We require more information by I will explain in principle:
If Type A has at least 300 hours and Type B at least 400 hours.
You need to determine the Probability density function of X and Y and then subtract 1 from both
This will give you the probability of the expression.
B. Standard form
Hope this helps
Answer:
3n^2(n^2+7n+9)
Step-by-step explanation:
Find the common factor. In this case, it is 3n^2. Take out the common factor of the integers.
So, therefore it is
3n^2(n^2+7n+9)
Answer:
Solution set of the quadratic equation is, Empty set
Step-by-step explanation:
Given the quadratic equation: 
Subtraction property of equality states that you subtract the same number to both sides of an equation.
Subtract both sides by 1 we get;
Simplify:
Division property of equality states that you divide the same number to both sides of an equation.
Divide both sides by 6 we get;
Simplify:
For any x in real number there does not exist any number x which satisfy
, therefore, there is no solution for this set of the quadratic inequality or in other word we can say that set of the solution is Empty set.
Answer:
The correct answer is:
There is a positive correlation because women's weight tend to increase when height increases (D)
Step-by-step explanation:
The units that might be used to measure each variable are:
Height : meter (m) or foot (plural, feet) (Ft.)
weight : kilograms (kg) or Pounds (lb)
A positive correlation is said to occur between two variables when they both move in the same direction, that is, when they both increase or decrease, while a negative correlation occurs when the movement is not in tandem, i.e, as one increases, the other decreases. The relationship between height and weight is a positive correlation because, an increase in height, which is mainly as a result of elongation of bones, leads to an accumulated increase in total body mass, which in turn increases the body weight.
