<h3>6x + y = -38 is the standard form of equation </h3>
<em><u>Solution:</u></em>
Given that,
y = -6x - 38
We have to write the equation in standard form using integers
<em><u>The standard form of equation is given as:</u></em>
Ax + By = C
Where,
x and y are variables and A, B, and C are integers
From given equation,
y = -6x - 38
Shift the variable terms to the left side of the equation and constants to right side of equation
<h3>6x + y = -38</h3>
Thus the standard form of equation is found
FALSE
The standard form of the equation of a circle is
With (a, b) representing the centre and r representing the radius.
The radius of the circle in the attachment is 5, and therefore the circle has the following equation.

Answer:
When the posiotive varibale is greater then the negative, the answer will be positive, when the negative variable is greater than the positive, the answer will be negative.
Explanation:
When adding a positive and a negative it could be either positve or negative ouput. If you had -50 and you added +60 the ouput is 10.
But if you had +50 and you added -60 the output would be -10.
Hope this helps you with your question!

Answer:
Step-by-step explanation:
We want to determine a 95% confidence interval for the mean mean test score of students.
Number of sample, n = 25
Mean, u = 81.5
Standard deviation, s = 10.2
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean ± z score ×standard deviation/√n
It becomes
81.5 ± 1.96 × 10.2/√25
= 81.5 ± 1.96/× 2.04
= 81.5 ± 3.9984
The lower end of the confidence interval is 81.5 - 3.9984 =77.5
The upper end of the confidence interval is 81.5 + 3.9984 = 85.5
Therefore, with 95% confidence interval, the mean test score of students is between 77.5 and 85.5
