Which equation represents the line that is perpendicular to y=1/6 and passes through (-8,-2)?
Answer:
y = -6x - 50
Step-by-step explanation:
y = mx + b
Since it is perpendicular to y=1/6, the slope is -6. (Opposite reciprocal)
y = -6x + b.
Substitute to get: -2 = 48 + b
b = -50
y = -6x - 50

the one with the Pepsi says
Coca-Cola - $1.29 for 1.25L
Pepsi - $2.49 for 2L and the Ib stands for pounds!!
The unit rate of the Coca-Cola is $ 1.032 and the unit rate of the Pepsi is $ 1.245.
Given, cost of Coca-Cola is
$1.29 for 1.25L
and cost of Pepsi is
$2.49 for 2L
we have to find the unit rate of each of the following,
As, the cost of Coca-Cola is
$1.29 for 1.25L
$1.29 = 1.25L
1 L = 1.29/1.25
1 L = $ 1.032
Now, the cost of Pepsi is
$2.49 for 2L
$2.49 = 2L
1 L = 2.49/2
1 L = $ 1.245
Hence, the unit rate of the Coca-Cola is $ 1.032 and the unit rate of the Pepsi is $ 1.245.

39.7 consumers believe that cash will be obsolete in the next 20 years. assume that 6 consumers are randomly selected. find the probability that fewer than of the selected consumers believe that cash will be obsolete in the next 20 years.
The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C & fewer than 3) = 0.1985
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
Here, we are required to find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.
Let Pr(C) be the number of consumers who believe that cash will be obsolete in the next 20 years.
Therefore, since 39.7% believe so,
Pr(C) = 39.7/100 = 0.397
If 6 consumers are selected randomly, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years will be;
Probability of 2 out 6 to believe so or Probability of 1 out of 6 to believe so.
Pr(2/6) + Pr (1/6)
Therefore the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is;
Pr (fewer than 3) = (2/6) + (1/6)
Pr (fewer than 3) = 3/6
Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C) × Pr (fewer than 3)
i.e 0.397 × (3/6) = 0.1985
Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C & fewer than 3) = 0.1985

Find the measure of each angle indicated by the “?”. Also tell me what type of angle it is for example: alternate exterior.
Answer: ? = 50, same side interior angles
? = 84, alternate interior angles
Step-by-step explanation:
130 + x = 180
-130 = -130
x = 50
alternate interior angles are congruent
50° is the value of the missing angle.
Since u and v lines are parallel so the angle asked and the angle with the value of 130° are alternate interior angle.
Alternate interior angles have the following characteristics:
They are congruent: Alternate interior angles are equal in measure. If one angle measures x degrees, the other alternate interior angle will also measure x degrees.They are on opposite sides: Alternate interior angles are located on opposite sides of the transversal.They are inside the parallel lines: Alternate interior angles are positioned between the two parallel lines.Therefore,
x+130 = 180
x =180-130
x =50°
therefore, the missing angle is 50°.

The X and Y angles created by lines intersection in the pictures are 18° and 54°.
Based on the picture, angle ∠MON is a right angle hence it has an 90° angle. We then know that the ∠MOA is 72°. Because angle ∠MOA lies within the angle ∠MON, hence we can write the following formula:
∠MON = ∠MOA +∠AON = 90°
∠MON = 72° + ∠AON = 90°
∠AON = 18° ... (i)
If we focus on the line CD being intersected by the line AB, hence we can conclude that the angles form by this intersection will follow these rules:
∠AOD = ∠BOC
∠AOC = ∠BOD
∠AOD + AOC = 180°
∠BOC + ∠BOD = 180°
Based on the picture, we know that:
∠BOC = x
∠AOC = ∠MOA + ∠MOC
∠AOC = 72° + y ...(ii)
∠AOD = ∠AON + ∠NOD
∠AOD = 18° +2x
∠BOC = 3x ... (iii)
Because we already know that ∠BOC = AOD, hence we could rewrite the formula into:
∠BOC = ∠AOD
3x = 18° + 2x
x = 18° ... (iv)
To find the value of y, we need to focus on angle ∠AOC. Based on the previous calculations and formulas, we know that:
∠AOC + ∠BOC = 180° ... (v)
Input equations (ii) and (iv) into (v)
∠AOC + ∠BOC = 180°
(72° + y) + 3x = 180°
72° + y + 3(18°) = 180°
126° + y = 180°

The solution of the system of the equations are; x = -2/3, y = -1/2 and z = 1.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The system of equation is given by;
3x − 4y + z = 2 ---- (1)
−9x + 12y − 3z = − 6 -------(2)
4x − 2y − z = -16 -----(3)
Now we add equations 1 from equation 3;
(3x − 4y + z ) + (4x − 2y − z ) = 2 -16
7x - 6y = -14 -----(4)
Further we multiply equation 3 by 3 and subtract from equation 2;
3(4x − 2y − z) - (−9x + 12y − 3z ) = -48 + 6
12x - 6y - 3z + 9x - 12y + 3z = 42

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes. Each small box can hold 25 books and each large box can hold 35 books. A total of 15 boxes were sent which can hold 455 books altogether. Determine the number of small boxes sent and the number of large boxes sent.
The number of small boxes sent is 7 and the number of large boxes sent is 8 .
In the question ,
it is given that ,
the number of books that a small box can hold = 25 books
the number of books that a large box can hold = 35 books .
let the number of small boxes be "s" ,
So , the total number of books in s boxes will be 25s .
since the total number of boxes given is 15 ,
So , the number of large boxes = 15 - s
So , the number of books in the (15-s) large boxes = 35(15-s),
also given that total books altogether = 455 ,
According to the question ,
the equation becomes
25s + 35(15-s) = 455
25s + 35*15 - 35s = 455
525 - 10s = 455
10s = 525 - 455
10s = 70
s = 70/10
s = 7 boxes
and large boxes = 15 - 7 = 8 boxes .
Therefore , The number of small boxes sent is 7 and the number of large boxes sent is 8 .

The mean will be increased by 2, and the standard deviation will remain the same (option D).
What happens to the mean and the standard deviation?The first step is to determine the initial mean and standard deviation of the data.
Mean is the average of a set of numbers.
Mean = sum of numbers / total number in the data
(2 + 3 +3 + 5 + 5 + 6) / 6
24 / 6 = 4
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.
Standard deviation of the initial data = √[{(2 - 4)² + (3 -4)² + (3 - 4)² + (5 - 4)² + (5 - 4)² + (6 - 4)²} / 6] = 1.414
Now, determine the mean and the standard deviation of the new data
New data : (2 + 2 =4)
3 + 2 = 5
3 + 2 = 5
5 + 2 = 7
5 + 2 = 7
6 + 2 = 8
Mean = (4 + 5 + 5 + 7 + 7 + 8) / 6 = 6
Standard deviation = √[{(4 - 6)² + (5 - 6)²+ (5 - 6)² + (7 - 6)² + (7 - 6)² + (8 - 6)²} / 6] = 1.41
