Answer:
19.2 m
Step-by-step explanation:
Since this is a right triangle, we can use the pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + 15^2 = c^2
144 + 225 = c^2
369 = c^2
Taking the square root of each side
sqrt(369) =sqrt(c^2)
19.20937271=c
To the nearest tenth
19.2 = c
Answer:
175
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
The value of is
Explanation:
The function is given by
The function is given by
To determine the value of , let us first substitute the value of
.
Thus, we get,
Now, substituting for in the function
, we get,
Simplifying, the expression, we get,
Multiplying the term within the bracket, we have,
Thus, the value of is
Hence, the value of represents the total amount of money that Barrett earns for working x hours.
