Answer: C. 6 inches high, 4 inches wide, and 10 inches long
Step-by-step explanation:
A scale model will have to use a scale factor that ensures that the actual measurements can be accurately converted to the scale model measurements in an equivalent manner.
This means that the real measurements need to be uniform when converted by the scale factor to the scale model. In other words, in this scenario for instance, when the scale measurements are divided by the real measurements, they should give the same scale factor.
Option C is correct because all the measurements give the same scale factor when divided as opposed to the rest.
Height = Scale/ Real = 6/3 = 2
Width = 4/2 = 2
Length = 10/5 = 2
They all use the scale factor of 1 feet: 2 inches so option C is correct.
Which function represents the total number of seats, h(x) = f(x)g(x)?
h(x) = 12x + 108
h(x) = 12x2 + 108x
h(x) = 12x – 108
h(x) = 12x2 + 108

E) Stratified
Answer:
Stratified sampling
Step-by-step explanation:
In the question, students are selected from subgroups of Sophomore, Junior, and Senior classes.
We are told that 49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
This means that the sample numbers of 49, 34 and 48 students were selected in proportion to the subgroup sizes of 496, 348, and 481 students respectively.
Thus, due to the fact that subgroups were selected & that sample number of students were also selected in proportion to their respective subgroup sizes, this is therefore a stratified sampling.
The type of sampling used in this scenario is stratified sampling. The type of sampling in this case is E) Stratified sampling.
The type of sampling used in this scenario is stratified sampling. Stratified sampling is a method where the population is divided into different groups or strata, and then a sample is randomly selected from each stratum. In this case, the sophomore, junior, and senior classes are the different strata, and the sample sizes are proportional to the size of each stratum.
To further explain, let's consider the sophomore class with 496 students. If we are selecting a sample size of 49 from this class, it means that approximately 10% of the students (49/496 = 0.098) will be selected. Similarly, for the junior class with 348 students, approximately 10% (34/348 = 0.098) of the students will be selected. The same applies to the senior class with 481 students and a sample size of 48 students.
In stratified sampling, the goal is to ensure that the sample represents the characteristics of each stratum in proportion to their size in the population. By sampling from each of the classes, we can obtain a representation of the entire student population.

Answer:
5 7/24
Step-by-step explanation:
Given the following mathematical expression;
12 5/8 - 7 1/3
First of all, we would subtract the whole numbers;
12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3
12 5/8 - 7 1/3 = 5 [5/8 - 1/3]
Next, we subtract the fractions from each other;
5/8 - 1/3
Lowest common multiple (lcm) = 24
5/8 - 1/3 = (15 - 8)/24
5/8 - 1/3 = 7/24
Combining the two parts, we have;
12 5/8 - 7 1/3 = 5 7/24
