Answer:
The procedure results in a binomial distribution
Step-by-step explanation:
If all 120 couples used the YSORT method, it is fair to assume that the probability of a baby being a boy or a girl are constant through all trials (120 couples). Assuming 120 randomly selected couples, there is a fixed number of independent trials. Finally, since the babies can only be a boy or a girl, the binary condition is satisfied and thus, the distribution is binomial
Answer:
-0.3125
Step-by-step explanation:
Subtract 3.5 from both sides
4t = -1.25
Divide both sides by 4
t =. -0.3125
Answer:
- the definition needs to restrict all of the points to a plane
Step-by-step explanation:
In 3-dimensional Euclidean space, a sphere is the set of all points the same distance from a given point. The given definition of a circle only applies when the given point and the solution set are in the same plane, and the geometry is Euclidean.
Answer:
Step-by-step explanation: Step 1: Isolate the absolute value expression.
Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.
Step 3: Solve for the unknown in both equations.
Step 4: Check your answer analytically or graphically.
Answer:
Step-by-step explanation:
Given
Let the roots be 
and 
So:
Required
Determine the relationship between d, c and p
Divide through by d
A quadratic equation has the form:
So:
So, we have:
-- (1)
and
-- (2)
Make the subject in (1)
Substitute in (2)
Multiply both sides by d
Cross Multiply
or
Hence, the relationship between d, c and p is:
