Given

Solving (a): The mean of the 6 samples.
This is calculated as:

So, we have:



Solving (b): The sample standard deviation.
This is calculated using:

So, we have:




Answer:
The number of cats an frogs
Step-by-step explanation:
For some reason the equation has (c+f) grouped off from the rest, since in an equation the first step is to take care of things in the parentheses, first you must add the two together, and based on the description, you know that c is the number of cats and f is the number of frogs. Therefore adding them together would get the total number of cats and frogs.
Answer:
x = 1
z = 1/2
Step-by-step explanation:
z = 3/y
z = 3/6
z = 1/2
x = 2z
x = 2(1/2)
x = 1
Let's review the terminology. A product is what you get when you multiply two numbers. So, the product of 5 and 2 is basically "5*2," and the product of 5 and 1 is "5*1."
The difference means when you subtract one from the other. So, the difference of 5*2 and 5*1 means "(5*2)-(5*1)". (Note: I put in parentheses to make sure the reader understands that 5*2 is separate from 5*1. 5*2-5*1 is confusing: you might not know what to do first!)
So, "(5*2)-(5*1)" can be your answer, OR you can simplify it further by actually doing the multiplication: "10-5". If you want the answer, just subtract--the expression is equal to 5.
Answer: "<span>(5*2)-(5*1)" OR "10-5" OR "5"</span>
Answer:
14.4
Step-by-step explanation:
You only move one space to the left since it is only one place to the lest with the decimal number .6
