Days in a week n(S)=7
DAYS to not getting monday n(M)=6
probability P(M)=n(M)/n(S)
=6/7(ans)
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
Answer:
Richard is right
Step-by-step explanation:
It just makes sense because with a parallelagram ll of the sides have to be close
Answer:
b. sampling distribution of the mean.
Step-by-step explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
The probability distribution of the sample mean is called the sampling distribution of the mean and it's a graph of the sampled data (mean).
Mathematically, sampling distribution of the mean is given by the formula;
uX = u.
Where, uX is the mean of the sampling distribution of the mean.
A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution is called a two-tailed test. Thus, it is two sided and is typically used to test whether a sample is less than or greater than a set of values.
