Answer:
This an example of inferential statistics.
Step-by-step explanation:
Descriptive statistics are used to briefly explain the distribution of a data by the use of central tendency and measure of variability. The descriptive coefficients are the representative of the sample or the whole population.
Inferential statistics is based on the inferences drawn, about the population, from the experiment conducted after selecting a sample from the population.
This is because the survey results are used to interpret the population proportion of class who are willing to take another math class.
Step-by-step explanation:
1. 'x' is the total no. of students and 'y' is no. of 6th graders.
1/3 of the total students are 6th graders.
So the equation will be
1/3 × x = y
x/3 = y
2. If x = 90
y = 90/3
y = 30
3. If x = 27,
y = 27/3
y = 9
4. If y = 42
x/3 = 42
x = 42 x 3
x = 126
Answer: i think it is A tell me if i am wrong!
Step-by-step explanation:
Step-by-step explanation:
x + 8a = 25 + ax - 7a
x = 5
5 + 8a = 25 + 5a - 7a
5 + 8a = 25 - 2a
5 + 10a = 25
10a = 20
a = 2
Answer: y = 2000x + 89000
Step-by-step explanation:
Given that;
initial purchase amount = $89,000
price after 6 years = $ 101,000
years = 6
now
slope = ( 101000 - 89000) / 6
slope = 12000 / 6
slope = 2000
therefore the linear equation that models the value of the house after x years will be;
y = 2000x + 89000
