You got it!!!!!! Just think about what you’ve been taught
first step )
with the equation +-b-√b∧2-4ac/2a you can find the zeros of the equation
second step)
for b= 0, a = 2, c = 32
+- 0-√o∧2-4(2)(32)/ 2*2 = √-256/ 4 , as you can see it, it is a negative number inside the root, and this equation do not have zeros, therefore it do not have solution
Answer:
The estimated value for the population standard deviation is $3,750.
Step-by-step explanation:
The interval within which the annual starting salaries for college graduates with degrees in business administration are generally expected to be is $30,000 and $45,000.
The standard deviation is the measure of dispersion or spread. And so is the range of the data.
Both the measures are used to determine how spread out the data is from the mean.
The relationship between standard deviation and range is not defined but according to the rule of thumb the standard deviation is one-fourth of the range of the data.
The formula of range is:
Compute the range of the data of starting salaries of college graduates with degrees in business administration as follows:
The range of the data is, $15,000.
Compute the estimated value of the standard deviation as follows:
Thus, the estimated value for the population standard deviation is $3,750.

Answer:
The dimensions of the box are 38.48 x 14.48 x 5.26 in.
Step-by-step explanation:
We will have a piece of cardboard with squares of side x cut from the corners to make a open box.
The volume of the box can be written as:
To calculate the maximum volume, we derive and equal to zero
We apply the quadratic equation to know the roots of the equation
The first solution is physically impossible, as the side that is cut would be bigger than 25.
So the real solution is for x=5.26 in.
Then, the dimensions of the box are:
