score of 80. The other students had an average score of 60. What is the average score of the
whole class?
The required average score of the class is 68.
Given that,
A class of 25 students took a science test. 10 students had an average (arithmetic mean) score of 80.
The other students had an average score of 60, which is the average score of the whole class is to be detrmined.
The average of the values is the ratio of the total sum of values to the number of values.
Here,
The average of 10 students is 80,
The average of the remaining students is 60 i.e. = 25 - 10 = 15
Now an average of the class,

Write the equation of the line in slope-intercept form.
4x=y-11
The equation of the line in slope-intercept form is y = 4x + 11 .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is 4x = y - 11 .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
4x = y - 11
On adding 11 on both sides in above equation, we will get
y = 4x + 11 equation 2
On equating equation 1 and equation 2, we will get
Slope of the line = m = 4
Intercept = c = 11
The equation of the line in slope-intercept form is y = 4x + 11 .

Write each number as a percent.
1/3
Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.
The number 1/3 as a percentage is 33.33 %.
What is a percentage?
A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The percent sign, %, is frequently used to indicate it. There is no unit of measurement for a percentage. It is a dimensionless number (pure number).
Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.
Let the number be 1/3 then
1/3 = 0.3333
To find percentage multiply it by 100, we get
So, 0.3333 × 100 = 33.33 %
Therefore, the number 1/3 as a percentage is 33.33 %.

Step-by-step explanation:
the angle is perpendicular
Determine if the conjectures below are true or false. If false, give a counterexample. Two right angles are always supplemetary.
The conjecture is always true, two right angles are always supplementary.
A pair of angles are supplementary only when the sum of those angles equals to 180°. In such a case each angle is said to be the supplement of another.
In case of parallel lines and a transversal two co-interior angles are supplementary. The opposite angles of a cyclic quadrilateral are supplementary angles .
For two angles to be supplementary only the sum of the angles matter and they should always be 180°.
The numerical value of right angle is 90° .
Therefore the sum of two right angles will be 90°+ 90° = 180°
So the conjecture which states that two right angles are supplementary will always stand as the sum of two 90°s is always 180°.
Hence the conjecture is true.

Simon wanted to find the equation of a line that passes through (–6, 5) and is perpendicular to the graph of 3x + 2y = –11. His work is shown below.
1. 3x + 2y = –11 written in slope-intercept form is y = x , so the slope is .
2. The slope of the perpendicular line is .
3. Substitute the point and the new slope into point-slope form to get y – 5 = (x – (–6)).
4. Simplifying, the line is y – 5 = (x + 6).
Is Simon’s work correct?
No, the slope of the line 3x + 2y = –11 is not .
No, the slope of the line perpendicular to the line 3x + 2y = –11 should be .
No, he did not substitute the point and the slope into point-slope form correctly.
Yes, the work is correct.
The answer would be: B. No, the slope of the line perpendicular to the line 3x + 2y = –11 should be 2/3.
What if the Slope of Perpendicular Lines?The equation in slope-intercept form of a line is, y = mx + b, where we have the slope value as m. If two lines are perpendicular, the value of their slope (m) will be negative reciprocals to each other.
Rewriting the equation, 3x + 2y = -11 in slope-intercept form, we would have:
2y = -3x - 11
y = -3/2x - 11/2
The slope (m) is, -3/2. The negative reciprocal is, 2/3.
Therefore, the slope of the line that is perpendicular to the given line would be: 2/3.
Thus, the answer would be: B. No, the slope of the line perpendicular to the line 3x + 2y = –11 should be 2/3.

Identify each sequence as arithmetic, geometric, or neither. Then find the next two terms. 1,4,9,16, . . . . . .
The sequence 1,4,9,16, . . . is neither an arithmetic nor a geometric sequence. In fact, it is a quadratic sequence. The next two terms are: 25 and 36
Given a sequence:
1,4,9,16, . . . .
To determine whether the sequence is an arithmetic, geometric, or neither, we need to check the relation between two consecutive terms.
Arithmetic sequence:
a(n) = a(n-1) + d
or a(n) - a(n-1) = d for all n
where d is a constant and is usually called common difference.
Geometric sequence:
a(n) = a(n -1) . r
or a(n)/a(n-1) = r, for all n
In the given sequence:
a(1) = 1
a(2) = 4
a(3) = 9
a(4) = 16
Check the difference:
a(2) - a(1) = 4 - 1 = 3
a(3) - a(2) = 9 - 4 = 5
Since the difference between 2 consecutive sequence is not a constant, then the sequence is not an arithmetic one.
Check the ratio:
a(2)/a(1) = 4
a(3)/a(2) = 9/4
Since the ratio of 2 consecutive sequence is not a constant, then the sequence is not a geometric one.
Thus the given sequence is neither an arithmetic, nor a geometric sequence. In fact, it is a quadratic sequence. Notice that:
a(n) = n²

The tables 2, 3 and 4 represent linear equations. (Correct choice: D)
Which tables do represent linear functions?
Algebraically speaking, linear functions are represented by a expression of the form y = m · x + b, where m is the slope of the function and b is the y-intercept of the line. Slope can be interpretated in accordance with the secant line formula:
m = Δy / Δ x
Where:
Δx - Change in independent variable.Δy - Change in dependent variable.In other words, a table represents a linear function if for all difference between two consecutive values in x means the same change for two corresponding values in f(x).
After a quick inspection, we find that tables 2, 3 and 4 represent linear as they show the following features:
