Answer:
The answer to your question is 14 students
Step-by-step explanation:
Data
Total students = 70
40% sixth-graders
20% seventh graders
40% eighth graders
The Number of seventh-graders = ?
Process
1.- Use proportions and cross multiplication to solve this problem
70 students ----------------------- 100 %
x ---------------------- 20 %
x = (20 x 70) / 100
x = 1400 / 100
x = 14 students are seventh-graders
70 students --------------------- 100 %
x --------------------- 40%
x = (40 x 70) / 100
x = 2800 / 100
x = 28 students are sixth graders
Eighth-graders = 70 - 14 - 28
= 28
Answer:The first one
Step-by-step explanation:
V rectangular prism = Area of the base *5
If you're meaning a value between 11 and 20, write
11<x>20 and put a line under the < and > which indicates that x could also equal 11 or 20. x doesnt only have to be a value between 11 and 20, but it can equal the numbers too.
i dont think that makes a lot of sense but if you were to say the answer out loud, the answer would be "x (which is any value) is more than or equal to 11 and less than or equal to 20"
Answer:
(c) A cluster sample
Step-by-step explanation:
A cluster sample occurs when the intended population is divided into non- overlapping sub -groups or clusters and some of these clusters are represented in the sample.
From the question, In a state 15 high schools where randomly selected and the standardized test was administered to only 10th grade student. Here, the high schools are the non-overlapping sub groups that is randomly selected and a reasonable representation of the entire subgroups.
Answer: Option: (B) The range of both f(x) and g(x) is all nonzero real numbers is correct.
