Answer:
The cookies cost $6 each, and $12 altogether.
Step-by-step explanation:
50-38=12, or x
Answer:
x + x + x + x is the same as 4x
because its "x four times"
5x and x+5 are not the same because x+5 in not "x five times"
5x is 5 multiplied by x.
x + 5 is 5 added to x.
<u>Given</u>:
The quadratic equation is 
We need to determine the solutions of the quadratic equation.
<u>Solution</u>:
Let us solve the equation to determine the value of x.
Adding both sides of the equation by 5x and 3, we get;

The solution of the equation can be determined using quadratic formula.
Thus, we get;



Thus, the two roots of the equation are
and 
Hence, the solutions of the equation are
and 
Answer:
Hello please your question is in-complete attached is the complete question
degree of freedom = -62.90 ( e )
Step-by-step explanation:
The formula for calculating the F-statistic/test statistic is
test - statistic = Coef ( LBW) / SE Coef ( LBW )
= -0.72399 / 0.01151
= - 62.90
the degree of freedom the F-statistic has = -62.90
F-statistic test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. the value of the test can be gotten from running an ANOVA test or regression analysis on the statistical models
