Centre of the circle (-6,-4) and radius =6 units :)
Answer:
The sample size is smaller than 30, so we need to assume that the underlying population is normally distributed.
The sampling distribution of x overbar will be approximately normally distributed with mean 63 and standard deviation 5.69.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem
The sample size is smaller than 30, so we need to assume that the underlying population is normally distributed.
If it is:
The sampling distribution of x overbar will be approximately normally distributed with mean 63 and standard deviation 5.69.
Answer:
257
Step-by-step explanation:
The divisors of 72 which are composite number are
4,6,8,9,12,18,36,72 (composite numbers are those numbers which are formed by the multiplication of two whole numbers}
So the total number of divisors which are composite are = 8
So total number of subset
In question it is said that also include empty set in count
So total number of subset =256+1=257
I believe the answer would be 24 square units
Answer:
Step-by-step explanation:
Joint variation problem solve using the equation y = kxz.
e ∝ fg
e=kfg
now substitute the values
The relationship will be:
