Answer:
The area of a rectangle is the product of the length and the width of the rectangle.
The dimensions chosen for length and width of a rectangle must be the lengths of two adjacent sides. The area is the product of the two dimensions. It does not make a difference which one you call length and which one you call width since length * width = width * length because of the commutative property of multiplication.,
Answer:
38.4
Step-by-step explanation:
We have 8/2.5=3.2 What does this mean? Well, it means that (if the miles are porportional to the dogs) that means he will see 3.2 as many dogs. So, we have 12*3.2=38.4, or 38 if the homework is asking for a rounded number. Hope I helped!
Answer:
70
Step-by-step explanation:
8 choose 4
= (8!)/(4!*4!)
=(8*7*6*5)/(4*3*2*1)
=1680/24
=70
2,148. you multiply 8950 by .76 to get 6802 and then you subtract that number from 8950, getting 2148
Answer:
The standard error of the mean for this sample is 9.033
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, we have that:
So
The standard error of the mean for this sample is 9.033
