Answer:  The answer is x=\pm\sqrt{3}..

Step-by-step explanation: The given equation is

8x^2-24=3x^2-9.

We are given to solve the above quadratic equation. Since there is no term containing 'x', so we will be using the square root method to solve the equation.

The solution is as follows:

8x^2-24=3x^2-9\\\\\Rightarrow 8x^2-3x^2=-9+24\\\\\Rightarrow 5x^2=15\\\\\Rightarrow x^2=3\\\\\Rightarrow x=\pm\sqrt{3}.

Thus, the required solution is  x=\pm\sqrt{3}.

Ok I'm not sure on how I would do the last bit of the equation but here's what I've got;   


Answer 1=                    -8 = -3

Answer2=                    -8 - 3= -11

Not 100% sure on this. so, I'm sorry if its wrong

A 2012 Gallup poll surveyed Americans about their employment status and whether or not they have diabetes. The survey results in
posledela

A) See picture for the table.

To make the table, multiply 47774 by 1.5% to get total that have diabetes and multiply 5855 by 2.5% to get total unemployed that have it, then using subtraction fill in the other squares of the table.

B)

Hypothesis:

H0: No association between employment and diabetes.

H1: Association between the two

Using a graphing calculator or Excel, run a chi-test.

Chi squared equals 31.844 with 1 degrees of freedom.

 The two-tailed P value is less than 0.0001

With this information we can reject the null hypothesis and conclude there is an association between diabetes and employment.

C)

Although there is a statistical significance, there really is no practical significance between an incidence rate of 1.5 or 2.5%

The median weight for a 5 foot tall male to enlist in the US Army is 114.5 lbs. This weight can vary by 17.5 lbs. Write and solv
myrzilka [38]

An absolute value inequality that represents the weight of a 5-foot male who would not meet the minimum or maximum weight requirement allowed to enlist in the Army is 97 lbs < x < 132 lbs.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

The median weight for a 5 foot tall male to enlist in the US Army is 114.5 lbs. This weight can vary by 17.5 lbs. Therefore, the inequality can be written as,

(114.5 - 17.5) lbs < x < (114.5 + 17.5) lbs

97 lbs < x < 132 lbs

Hence, an absolute value inequality that represents the weight of a 5-foot male who would not meet the minimum or maximum weight requirement allowed to enlist in the Army is 97 lbs < x < 132 lbs.
