Answer:
Qualitative variable
Step-by-step explanation:
The response is qualitative variable due to its possible categories. In short, the response can only be divided into categories and cannot be interpreted numerically in a meaningful way. Thus, response is a qualitative variable. Also, the categories involves ordering like better and worse etc so, the measurement of scale would be ordinal in this scenario.
This is a problem of
system of linear equations in two variables. This concept of mathematics is very useful in real-life problems. You can solve a system by finding the solution. A
solution of a system are the values of the variables that satisfies each equation in the system. So by knowing these concepts we can get a system of equation by analyzing each statement step by step, that is:
1. Alice has a total of 12 dimes and nickels.
Let the variables:

1st. Equation:

<span>
2. She has 2 more nickels than dimes
2nd Equation:

Therefore our system of linear equations is:
</span>
Conclusion:<span>Alice has
5 dimes and
7 nickels. </span>
Cotangent of angle A=base/height=24/10=12/5
cotangent of B=10/24=5/12
Answer:
Step-by-step explanation:
y - 5 = -2(x + 4)
y - 5 = -2x - 8
y = -2x - 8 + 5
y = -2x - 3 <====
or this one..
y = -2x - 3
2x + y = -3 <===
