The answer is:
100
The explanation is that if you follow PEMDAS you will get that answer.
it means i only paid for %10 out if the 100%.
so therefore, the original price is;
100/10×80=$800
Let n represent the unknown numbers.
*we add 2 and 4 to the numbers so that we are sure that they will be even*
n + (n+2) + (n+4) = - 300 *simplify*
n + n + 2 + n + 4 = - 300
3n+6=-300
-6 -6
--------------- *Get constants and variables to either side*
3n = - 306
--- ------ *Isolate the variables*
3 3
n= - 102
Then plug this in for the above values
n+2= - 102+2= -100
n+4= - 102+4 = -98
Answer:
The 95% confidence interval
Step-by-step explanation:
From the question we are told that
The sample mean is
The standard deviation is
The sample size is n = 8
Given that the confidence level is 95% then the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence interval is mathematically represented as
=>
=>
