The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Given the equations:
x = 4y
x - 4y = 0 (1)
Also:
x - y + 3z = 3 (2)
And:
2x - 3y - z = -7 (3)
The solution to the equation is:
x = -4, y = -1 and z = 2
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2

Answer:
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
Step-by-step explanation:
given that a newsletter publisher believes that less than 26% of their readers own a Rolls Royce.
For marketing purposes, a potential advertiser wants to confirm this claim.
After performing a test at the 0.10 level of significance, the advertiser failed to reject the null hypothesis.
For this the hypotheses would be
H0: p = 0.26
Ha: p <0.26
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.
Answer:
Since each cracker in the 190 gram box costs $ 0.0078 while the 850 gram box costs $ 0.0082 each, the 190 gram box is a better deal.
Step-by-step explanation:
Knowing that a 190-gram box of crackers costs $ 1.49 and an 850-gram box costs $ 6.99, to determine which of them is a better deal, the following calculation must be performed:
1.49 / 190 = 0.0078
6.99 / 850 = 0.0082
Therefore, since each cracker in the 190 gram box costs $ 0.0078 while the 850 gram box costs $ 0.0082 each, the 190 gram box is a better deal.
It equals 2 in my opinion
