What is an equation of the line that passes through the point (6,1) and is
perpendicular to the line 2x + 3y 18?
Answers
Answer:
y - 1 = 3/2(x - 6)
Step-by-step explanation:
First, we need to find the slope of the given equation. Without a graph, the easiest way to do this is by isolating y.
2x + 3y = 18
3y = -2x + 18 (Subtract 2x from both sides)
y = -2/3x + 6 (Divide both sides by 3)
The slope is -2/3. Perpendicular lines have opposite reciprocal slopes, so a line perpendicular to this one would need to have a slope of 3/2. We're given a point for this line, so we can write the equation for it in point-slope form.
Point-Slope Form: [tex]y - y_{1}=m (x-x_{1})[/tex]
y - 1 = 3/2(x - 6)
If necessary, this can also be written in slope-intercept form by solving for y.
Please give me the correct answer.Only answer if you're very good at math.

Reduced ratios are found by removing (dividing out) the greatest common factor (GCF). For several of these, that factor is the smallest number or the difference between the numbers. Knowledge of multiplication tables is helpful.
9 : 36 = 1 : 4 . . . . common factor of 9
21 : 27 = 7 : 9 . . . . common factor of 3
48 : 72 = 2 : 3 . . . . common factor of 24
60 : 45 = 4 : 3 . . . . common factor of 15
10 : 70 = 1 : 7 . . . . common factor of 10

Comment on GCF
The greatest common factor can be found from your knowledge of multiplication tables and/or divisibility rules. It can also be found using Euclid's algorithm. For that, you ...
Divide the larger number by the smaller and keep the remainder.
If the remainder is 0, the smaller is the GCF.
If the remainder is not zero, replace the larger number with the remainder and repeat from the first step.
Example:
27/21 = 1 r 6
21/6 = 3 r 3
6/3 = 2 r 0 . . . . 3 is the GCF of 21 and 27

O The subjects in the study are not representative of the population, because some members of the population refused to take part in the study.
Answers
Answer:
The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.
Step-by-step explanation: i got it right on the test
A sample is said to exhibit undercoverage bias, if some of the portion or category of the population are not adequately represented or exempted from the selected sample. Hence, undercoverage bias exists because, The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.
Undercoverage bias produces non - representative samples as some category of the population may have been exempeted from the study. Hence, option C is correct.Undercoverage translates that the opinion of some members of the population were not even considered. Hence, the introduction of undercoverage bias.

The HCF of 130, 325 and 845 is equal to 65.
Step-by-step explanation:
We need to find the HCF of 130, 325 and 845.
First, we see the prime factors of the above numbers i.e.
The factors of 130 are: 1, 2, 5, 10, 13, 26, 65, 130
The factors of 325 are: 1, 5, 13, 25, 65, 325
The factors of 845 are: 1, 5, 13, 65, 169, 845

the average mark of three pupils are 68. what is the ratio of 5:4:3. how many marks did the best student get? HELP ME!
Answers
Answer:
85, 68, 51
Step-by-step explanation:
Average: The sum of all the numbers divided by the number of numbers
If the ratio of the scores is 5 : 4 : 3, let's just set it as 5x : 4x : 3x
Then using the definition of an average, we can write this equation.
(5x + 4x + 3x) / 3 = 68
Multiply both sides by 3.
5x + 4x + 3x = 68 * 3
Simplify.
12x = 204
x = 17
Now, substitute x = 17 into the original scores (5x, 4x, and 3x)
5x = 5 * 17 = 85
4x = 4 * 17 = 68
3x = 3 * 17 = 51
Just in case, let's check this answer. Find the average of the 3 test scores.
(85 + 68 + 51) / 3 =
204 / 3 = 68
Thus, the answers are correct
