Answer:
300 dollars
Step-by-step explanation:
60% of 500
(60/100) * 500 = 300
<span>4.8 - 0.2 × 11.5</span><span>
u must do the multiplication first following the rule
</span>0.2 × 11.5 =2.3 <span>
4.8 - 2.3 = 2.5
</span>PEMDAS rule follow this order
parenthesis, exponents, multiplication, division, addition, subtraction.
Answer:
Step-by-step explanation:
In this problem we have the equation of the following quadratic equation and we want to solve it using the method of square completion:
The steps are shown below:
For any equation of the form: 
1. If the coefficient a is different from 1, then take a as a common factor.
In this case 
.
Then we go directly to step 2
2. Take the coefficient b that accompanies the variable x. In this case the coefficient is -3. Then, divide by 2 and the result squared it.
We have:
3. Add the term obtained in the previous step on both sides of equality:
4. Factor the resulting expression, and you will get:
Now solve the equation:
Note that the term 
is always > 0 therefore it can not be equal to 
The equation has no solution in real numbers.
In the same way we can find the complex roots:

Answer: ANOVA
Step-by-step explanation:
The statistical procedure that a college admissions office would use if they wanted to know if doing physical exercises can help the same group of students improve their GPA is the ANOVA.
Analysis of variance is used to know whether the means there's a significant difference between two or more groups. Different sample means will be compared in order to checks the effect of the factors involved. Based on the question above, the null hypothesis will be that physical activity doesn't have a significant relationship with the GPA of the college students.
