Which is the equation of the line that passes through the point (-4,3) and (2,6)
Answer:
[tex]\displaystyle y = \frac{1}{2}x + 5[/tex]
Step-by-step explanation:
Equation of a Line
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
Suppose a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We'll use the points (-4,3) and (2,6), thus:
[tex]\displaystyle m=\frac{6-3}{2+4}=\frac{3}{6}=\frac{1}{2}[/tex]
Now we use the point-slope form using the point (2,6):
[tex]\displaystyle y - 6 = \frac{1}{2}( x - 2 )[/tex]
Operating:
[tex]\displaystyle y - 6 = \frac{1}{2}x - 1[/tex]
[tex]\displaystyle y = \frac{1}{2}x - 1 + 6[/tex]
[tex]\boxed{\displaystyle y = \frac{1}{2}x + 5}[/tex]

Given:
Total number of students = 20
The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.
To find:
The frequency distribution table with class size 10.
Solution:
We have, the marks of 20 students.
40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40
Here,
Minimum value = 12
Maximum value = 48
We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.
The required frequency distribution table is
Class intervals Marks Frequency
10-20 12, 15 2
20-30 22, 27, 20, 25 4
30-40 36, 30, 31, 34, 36, 39, 36, 37 8
40-50 40, 41, 43, 48, 46, 40 6
Total 20
Therefore, the frequency distribution table is
Class intervals: 10-20 20-30 30-40 40-50 Total
Frequency : 2 4 8 6 20

Answer:
z = 66
Step-by-step explanation:
RS = z
QT = z - 33
Based on the midsegment theorem, QT = ½(RS)
Plug in the values
z - 33 = ½(z)
Multiply both sides by 2
2(z - 33) = z
2z - 66 = z
Add 66 to both sides
2z = z + 66
Subtract z from both sides
2z - z = 66
z = 66
The graph shows the career interests of the students at Linda’s school. Suppose there are 400 students at the school. How many of them want to be an athlete? (Example 1)
Step-by-step explanation:
Percentage of students who want to be an athlete
= 12%.
400 students * (12%/100%) = 48 students.
Hence 48 students want to be an athlete.
The number of athletes students which are 12% of 400 students will be 48.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The graph shows the career interests of the students at Linda’s school. Suppose there are 400 students at the school.
From the graph, the percentage of athletes is 12%.
The number of athletes students which are 12% of 400 students will be given as,
⇒ 12% x 400
⇒ 0.12 x 400
⇒ 48
The number of athletes students which are 12% of 400 students will be 48.

A doctor wants to determine if a new medication for cholesterol is more effective than the previous medication. The doctor informs his patients of the new medication and asks if they want to participate in a study. Patients who are currently taking medication for cholesterol are randomly selected and given the new medication. After two months, the patients’ cholesterol levels are checked.
Which of the following would benefit this experiment the most?
A This experiment should also use the original medication to see if the patients’ cholesterol levels would improve because they believe they are receiving the new medication.
B This experiment should use blinding and a placebo, so patients do not know which treatment they are receiving and to control for the placebo effect.
C This experiment should be single blind, with some patients taking the new medication and some taking the original medication to determine the effects of the new medication. Only the subjects would not know which treatment they are receiving.
D This experiment should be double blind, with some patients taking the new medication and some taking a placebo to determine the effects of the new medication. Neither the subjects nor the technicians checking the cholesterol would know which treatment was given to which group.
Answer:
its option 3
Step-by-step explanation:
got 100% on it
Blinding and placebo should be used in this experiment to prevent patients from knowing which therapy they are receiving and to account for the placebo effect.
What is the placebo effect?A person experiences the placebo effect when their physical or mental health seems to get better after receiving a placebo or "dummy" treatment. A treatment that seems to be real but is intended to have no therapeutic benefit is referred to as a placebo.
Given, If a new cholesterol drug is more successful than the old one, a doctor wants to know. The doctor tells his patients about the new drug and inquires about their interest in taking part in a trial. Randomly chosen patients who are already receiving cholesterol medication are given the new drug. The patients' cholesterol levels are assessed after two months.
Treatments with placebos cause the brain to react in a real way. Belief in the efficacy of a treatment can cause the release of neurotransmitters, the synthesis of hormones, and immunological response, which can reduce the symptoms of pain, inflammatory diseases, and mood disorders.
Therefore, In order to keep patients from knowing which therapy they are taking and to take the placebo effect into account, blinding and placebo should be employed in this experiment.

What is an aquifer?
Why is gravity part of the water cycle ?
Answer:
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Gravity pulls denser air and water downward, forcing less dense air and water to move upward.

what is the answer to this ⅓(6x-9)
Answer:
3 - 2x
Step-by-step explanation:
Answer:
9-9x = 0 x=1
Step-by-step explanation:
Put each term in 6+(-9-6 x)/3-x over the common denominator 3: 6+(-9-6 x)/3-x = 18/3+(-9-6 x)/3-(3 x)/3:
18/3+(-9-6 x)/3-(3 x)/3 = 0
18/3+(-9-6 x)/3-(3 x)/3 = (-3 x+(-9-6 x)+18)/3:
(-3 x-6 x-9+18)/3 = 0
Grouping like terms, -3 x-6 x-9+18 = (18-9)+(-6 x-3 x):
((18-9)+(-6 x-3 x))/3 = 0
-6 x-3 x = -9 x:
(-9 x+(18-9))/3 = 0
18-9 = 9:
(9-9 x)/3 = 0
Multiply both sides of (9-9 x)/3 = 0 by 3:
(3 (9-9 x))/3 = 3×0
(3 (9-9 x))/3 = 3/3×(9-9 x) = 9-9 x:
9-9 x = 3×0
0×3 = 0:
