We are given : A stock is represented by -5.90.
The given number is a negative number.
Note: When a stock is given by a negative number, it represents the decrease in stock and when a stock is given by a positive number, it represents the increase in stock.
As we are given number is a negative number, we can just say that
" The stock value is being decrease by 5.90".
Answer:
This study is good because we have minimized sampling error.
Step-by-step explanation:
We are given that . The researcher has two groups.
The researcher classifies the students based on when they volunteer for the study.
The first 50 students who volunteer receive online instruction. The next 50 receive instruction by attending a class with a teacher.
A. This study is poor because the researcher did not use random sampling.
B. This study is poor because the researcher did used random sampling.
C. This study is good because we have minimized sampling error.
D. This study is good due to the equal sample size in each group.
Option C is true : This study is good because we have minimized sampling error.
Answer:
A, E
Step-by-step explanation:
The question is not biased. It does not use positive or negative language. However, the sample is biased because it only represents new employees, not the whole company.
So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.
Step 1: Translate the word problem into an equation
Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.
Equation: 
+ x = 
Step 2: Isolate x by subtracting from each side
+ x - = -
Step 3: The numbers on the left cancel out, leaving x alone
x = 
Step 4: Convert the answer to decimals
x = 3.6
