Answer:
a) Quantitative; discrete
b) Qualitative
c) Quantitative; continuous
Step-by-step explanation:
Quantitative and Qualitative:
- Qualitative variables are the non-parametric variables.
- Quantitative variables are the variables whose values are expressed in the form of number.
- Qualitative is information about a variable where as quantitative describes the variable with the help of values.
Discrete and Continuous:
- Quantitative variables whose values are expressed in the form of whole numbers are discrete variable.
- Discrete variable cannot take all the values of an interval. They are counted not measured.
- Quantitative variable whose values can be expressed in the form of decimals are continuous variable.
- Continuous variable take all the values within interval. They are measured not counted.
a. Points scored in a football game.
Since the points are expressed in numerical. Thus, they are quantitative variable. Since points are always expressed in whole numbers and are always counted it is a discrete variable.
b. Racial composition of a high school classroom
This will include the categorical values and not expressed as numerical. Thus, it is qualitative variable.
c. Heights of 15-year-olds.
These values will be expressed with the help of numerical and can take any value within an interval. Also, height is always measured and not counted. Thus it is a continuous variable.
Find the surface area:
7.25 x 9.5 x 2 = 137.75 gets the surface area of the two rectangle sides.
To get the bottom rectangle, do 8 x 9.5 = 76
To find the two triangles, do 6 x 8 x 0.5 x 2 = 48
Now add them all together: 137.75+76+48=261.75
So, the answer is 261.75 square feet of material.
What’s your question/what do you need help with?
Answer:
1/36
Step-by-step explanation:
There are 6 numbers on a die. You have a 1/6 chance of rolling a 3 and a 1/6 chance of rolling a 4. 1/6 times 1/6 = 1/36.
