$2p=7+q \\
6p-3q=24 \\ \\ 
\hbox{divide the second equation by 3:} \\
\frac{6}{3}p-\frac{3}{3}q=\frac{24}{3} \\
2p-q=8 \\ \\
\hbox{substitute 7+q for 2p in the equation:} \\
7+q-q=8 \\
7=8 \\
not \ true \\ \\
\boxed{\hbox{no solutions}}$

Suppose that the hourly wages of fast food workers are normally distributed with an unknown mean and standard deviation. The wag

Nutka1998 [239]

Answer: 1.303639

Step-by-step explanation:

The t-score for a level of confidence $(1-\alpha)$ is given by :_

$t_{(df,\alpha/2)}$ , where df is the degree of freedom and $\alpha$ is the significance level.

Given : Level of significance : $1-\alpha:0.80$

Then , significance level : $\alpha: 1-0.80=0.20$

Sample size : $n=40$

Then , the degree of freedom for t-distribution: $df=n-1=40-1=39$

Using the normal t-distribution table, we have

$t_{(df,\alpha/2)}=t_{39,0.10}=1.303639$

Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639

Simplify. (x−3)( x^2−4x−7)

Shkiper50 [21]

Answer:

Simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .

Step-by-step explanation:

As the expression given in the question be as follow .

= (x−3)( x²−4x−7)

simplify the above

= x (x²-4x-7)-3 (x²-4x-7)

Now open the bracket

= x³ - 4x² -7x - 3x² + 12x + 21

= x³- 4x²-3x²-7x + 12x + 21

= x³ -7x² + 5x + 21

Thus the simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
