It is an infinite number of solutions. To put it simply, is x = 1, y would equal 4.you can do this with every single number.
In its normal way, For example: 214, Write it in the way it is Usually written.
Answer:
The confidence interval is 6.6<μ<6.8.
Step-by-step explanation:
We have:
Number of observations = 601
Mean = 6.7
Standard deviation σ = 1.5
The z-score for a 95% confidence interval is 1.96.
The limits of the confidence interval can be calculated as

The confidence interval is 6.6<μ<6.8.
The equation of y in terms of x is y =(c/b) - (a/b)x
<h3>What is an Equation ?</h3>
An Equation is a mathematical statement formed when two algebraic expressions are equated with an equal sign.
The equation given in the question is
ax + by = c , b ≠ 0.
Express y in terms of x in the equation
by = c - ax
y = (c/b) - (a/b)x
Therefore the equation of y in terms of x is y =(c/b) - (a/b)x

Answer:
The 80% confidence interval for the mean
(4.6199 , 4.7801)
Step-by-step explanation:
<u>Explanation</u>:-
Assuming that the population standard deviation for the number of energy drinks consumed each week is 1
Given the Population standard deviation 'σ' = 1
The study found that for a sample of 256 teenagers the mean number of energy drinks consumed per week is 4.7
given sample size 'n' = 256
mean of the sample 'x⁻' = 4.7
<u>confidence interval for the mean</u>
The 80% confidence interval for the mean is determined by

the z-score of 80% level of significance = 1.282

(4.7 - 0.0801 , 4.7 +0.0801)
(4.6199 , 4.7801)
<u>Conclusion</u>:-
The 80% confidence interval for the mean
(4.6199 , 4.7801)
