The lines below are perpendicular. If the slope of the green line is ą, what is
the slope of the red line?
Answer:
See below
Step-by-step explanation:
If i recall right when two slopes are perpendicular one slope is supposed to be the negative reciprical of the other slope, because of this I think your answer should be B. -\frac{2}{3}
Hope this helps
The lines are perpendicular and the slope of the red line is m₂ = -2/3
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m₁ = 3/2
So , the slope of the green line is m₁ = 3/2
Since the lines are perpendicular to each other , the product of their slopes will be equal to -1
And , m₁ x m₂ = -1
So , ( 3/2 ) x m₂ = -1
Multiply by ( 2/3 ) on both sides , we get
m₂ = ( -2/3 )
Therefore , the slope of the red line is ( -2/3 )
Hence , the slope of the red line m₂ = ( -2/3 )

What is important to keep in mind when selecting a sample?
a. The sample should be chosen based on specific criteria, such as the youngest students in the
class.
b. The sample should be chosen at random so that it is fair.
c. The sample should consist of every person in the population being studied.
d. The sample size should always be exactly one person or piece of data.
Answer: b. The sample should be chosen at random so that it is fair.
Step-by-step explanation:
Looking at the options:
a. The sample should be chosen based on specific criteria, such as the youngest students in the class.
This is false. Choosing a sample size based on specific criteria may skew the data unfairly. For example, in a survey on students' studying habits, choosing only the students with lowest grades would be an inaccurate representation of the data.
b. The sample should be chosen at random so that it is fair.
This is true. Randomizing a sample eliminates any bias, whether intended or unintended.
c. The sample should consist of every person in the population being studied.
Although it is ideal to survey every person in order to get the most accurate data, doing so is often impossible given the scope of a data set. Doing a survey on high schooler's study habits cannot possibly get data from every person in the population, as there are high school students across the world.
d. The sample size should always be exactly one person or piece of data.
One person's data is not a survey, it is just an opinionated study. Sample size should always be large enough to eliminate any accidental bias.
The correct choice is B.

Answer: 18 square feet.
Step-by-step explanation:
You can find the surface area of the ice cubes by taking the area of each square side and multiplying it by 6.
1 * 1 = 1, so each side is 1 square foot.
There are six sides on a cube, so each ice cube has a surface area of six feet squared.
There are three ice cubes there, so 3 * 6 = 18 square feet.
Three ice cubes have a surface area of 18 feet squared.

The average mark of candidate in an aptitude test was 128.5 with a standard deviation of 8.2. Three scores extracted from the test are 148, 102,152. What is the average of the extracted scores t hat are extreme values (outliers)?
Answer:
Step-by-step explanation:
Given that : The average marks of candidates in an aptitude test was 128.5 with a standard deviation of 8.2. Three scores extracted from the test are; 148, 102 and 152.
The objective here is to determine the average of the extracted scores that are the extreme values (outliers)
NOW:
The average marks of candidates in an aptitude test was 128.5
i.e the Mean = 128.5
Standard Deviation = 8.2
outlier will be outsides;
then the range will be Mean ± 3 × SD
= 128.5 ± 8.2 × 3
= 128.5 ± 24.6
Range is ( 103.9 , 153.1)
102 is outside this range
Hence, the average of the extracted scores that are extreme values (outliers) will be 102 only
in your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you were getting dressed, and you can’t see the color of the socks. How many socks must you pick to absolutely guarantee that you have a pair of blue socks to wear?
A.) 14
B.) 24
C.) 4
D.) 3
E.) 2
Answer:
A. 14
Step-by-step explanation:
The smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A)
What is pigeonhole principle?If there are n objects to be putted into m containers such that n > m, then at least one container will have two objects.
Suppose the worst is happening when you're pulling the socks out.
The total number of colors is 2.
Now the worst case is when the pair is not completed until we draw all the yellow color.
That will happen at 12 + 1 = 13 draws (pair needs 2 blue, and the worst will happen that in initial trials, the yellow socks are not letting the pair get completed, which means at max 1 blue sock and rest 12 socks are drawn, which will get at max 13 draws).
But now any more sock pulled will have to be falling into the blue color category we already have. (this is exactly the pigeonhole principle's use).
After 13 times, you will start getting blue socks.
Since you need a pair of blue socks, you need to pull out socks 1 more time.
So total 14 pulls were required if the conditions were like resisting us at maximum.
In most of the cases, we might not need those 14 pulls, but 14 pulls is the minimum number that will assure you that the socks pulled have a blue pair of socks.
If the conditions are not worst, we would be lucky and that
Thus, the smallest number of socks to pull out to be assured that we get a blue pair of socks is 14. (Option A is correct).

Answer:
no they're not
Step-by-step explanation:

4x+2= 4x+2
Answer:
No they are not equivalent
First we would have to solve 4(x+2)
In order to solve this we need to multiply. So 4×X is equal to 4x. 4×2=8 Therefore when solving Its 4x+8..and 4x+8 is not equivalent to 4x+2
A biologist tags 25 birds with a band on their foot and lets them go back into the wild. The next year 100 total birds are captured and 5 of them have the foot bands. Enter an estimate of the total bird population. 20
Answer:
We can estimate a population of 500 birds.
Step-by-step explanation:
We can estimate the total bird population using a rule of three with the information given:
If we find 5 birds with the foot band among 100 birds captured, how many birds there are in total if inicially we put foot bands in 25 birds?
5 birds with foot band -> 100 birds captured
25 birds with foot band -> X total birds
X * 5 = 25 * 100
X = 25 * 100 / 5 = 500 birds
We can estimate a population of 500 birds.

4. Would a 51-foot ladder be long enough to climb a 50-foot wall? Sketch a graph and find your answer using trigonometric functions
Answer:
Yes, it is enough to climb.
Step-by-step explanation:
Let suppose that wall is vertical and perpendicular to surface, a right-angled triangle is formed after using the ladder against the wall. (See attachment)
Ladder is useful only if its length is greater than wall length and trigonometrically speaking, the ratio of wall length to ladder length must be less than 1, associated with the definition of sine. That is:
[tex]\sin \theta = \frac{50\,ft}{51\,ft}[/tex]
[tex]\sin \theta = 0.980[/tex]
In a nutshell, the 51-foot ladder is useful to clime a 50-foot wall.
The rectangle below has an area of x^2-6x-7 sq meters and a width of x-7 meters.
What expression represents the length of the rectangle?
Length=______ meters
Answer:
Length = ( x - 1 ) ( m)
Step-by-step explanation:
Area of rectangle is:
A(r) = l*w ( in m² ) where l is the length in m and w is the width in m
If we have: A(r) = x² - 6*x - 7 (m²), as an area of a rectangle, then we can factoring the equation, and get the rectangle dimensions, then:
x² - 6*x - 7 = ( x - 1 ) * ( x - 7 ) = area of the rectangle in m²
As problem statement establishes that ( x - 7 ) ( m) is the width, then
( x - 1 ) ( m) is the length

Answer:
1) I think its helps to rename a function as tenths or hundredths when you want to write the decimal equivalent because for example if you wanted to rename this function 6/25 to 24/100 you can know were you put it in decimal (0.24).
2) It was a good idea to change 4/16 to 1/4 to determine a decimal equivalent because it would be easier to put 1/4 in a decimal equivalent.

Answer:
Step-by-step explanation:
1) 7x - 14 = 2x + 11 {Add 14 to both sides}
7x - 14 +14 = 2x + 11 +14
7x = 2x + 25
7x - 2x = 2x + 25 - 2x
5x = 25 {Divide both sides by 5}
5x/5 = 25/5
x = 5
2) 6x + 5 = 3x + 14

12x - 4x = 32
8x = 32
x = 32/8
x = 4
4) 3x + 8 = 2x + 21
3x = 2x + 21 - 8
3x = 2x + 13
3x - 2x = 13
x = 13
5) 5x + 3 = x + 11
5x = x + 11 -3
5x = x + 8
5x - x = 8
4x = 8
x= 8/4
x = 2
Answer: Step-by-step explanation:
1) 7x - 14 = 2x + 11 {Add 14 to both sides}
7x - 14 +14 = 2x + 11 +14
7x = 2x + 25
7x - 2x = 2x + 25 - 2x
5x = 25 {Divide both sides by 5}
5x/5 = 25/5
x = 5
2) 6x + 5 = 3x + 14
6x = 3x + 14 - 5
6x = 3x + 9
6x - 3x = 9
3x = 9
x = 9/3
x = 3
3) 12x + 5 = 4x +37
12x = 4x + 37 - 5
12x = 4x + 32
12x - 4x = 32
8x = 32
x = 32/8
x = 4
4) 3x + 8 = 2x + 21
3x = 2x + 21 - 8
3x = 2x + 13
3x - 2x = 13
x = 13
5) 5x + 3 = x + 11
5x = x + 11 -3
5x = x + 8
5x - x = 8
4x = 8
x= 8/4

When we complete the square, we take the b value from the equation:
a[tex]x^{2}[/tex] + bx + c = 0, and plug it into [tex](\frac{b}{2})^{2}[/tex] ..
First step is to make the coefficent of x go away. By dividing by 4.
x^2 - 3x + 9/4 = 0
now plug into the equation
(-3/2)^2 = 9/4 <-- because the square is parantheses, the negative goes away. Notice how there is a 9/4 already in our equation, meaning we dont have to do anything and simply can find the answer!
