Answer:

Hello, I think the answer is C) Votes counted for each candidate in a election

Step-by-step explanation:

Is the variable qualitative or quantitative? The variable is quantitative because it is a numerical measure. A variable that may assume only a countable and usually finite, number of values. Quantitative variables take numerical values and represent some kind of measurement. In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. Weight and height are also examples of quantitative variables. Quantitative information or data is based on quantities obtained using a quantifiable measurement process. In contrast, qualitative information records qualities that are descriptive, subjective or difficult to measure. Statistics, also known as quantitative analysis. Numerical data, also known as quantitative data. <em>Hope That Helps!</em>

Find the slope and y intercept of the graph of the graph of each equation.

AleksandrR [38]

Solve each equation for y and then the slope is m and y-intercept is b as in:
$y = mx+b$

So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1

Hope this helps.

Complete Question

Polymer composite materials have gained popularity because they have high strength to weight ratios and are relatively easy and inexpensive to manufacture. However, their nondegradable nature has prompted development of environmentally friendly composites using natural materials. An article reported that for a sample of 10 specimens with 2% fiber content, the sample mean tensile strength (MPa) was 51.1 and the sample standard deviation was 1.2. Suppose the true average strength for 0% fibers (pure cellulose) is known to be 48 MPa. Does the data provide compelling evidence for concluding that true average strength for the WSF/cellulose composite exceeds this value? (Use α = 0.05.)
