Step-by-step explanation:
The sample size n in<em> Simple Random Sampling</em> is given by
<em>
where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation.
</em>
Replacing values
So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000
Answer:
2y² + 9
---------------
15y³
Step-by-step explanation:
Start by identifying the LCD, and then change each fraction so that its denominator is the LCD.
Here the LCD is 15y³, which is evenly divisible by 15y and 5y³.
Focus now on the first fraction: 2 / (15y). Multiplying numerator and denominator of this fraction by y² results in
y²·2 2y²
--------- → ----------
y²·15y 15y³ ←This is the correct LCD
Multiplying numerator and denominator of the second fraction by 3 results in:
3·3 9
------------ → ---------
3·5y³ 15y³ ←This is the correct LCD
So now those two original terms look like:
2y² 9
--------- + --------
15y³ 15y³
and this can be written in simpler form as:
2y² + 9
---------------
15y³
Answer:
1.47 mm
Step-by-step explanation:
In week 1 there was 2.6 mm
In week 4 there was 4.07
You want to find the difference of week 1 and 4 meaning you have to subtract week 4's value from week 1's to find how much more rain there was in week 4 than week 1
You would do 4.07-2.6
This is equal to 1.47
THEREFORE there was 1.47 mm more rain in week 4 than week 1
