Answer:
The correct answer is 1128 fist bumps exchanged.
Step-by-step explanation:
Each friend exchanges 47 fist bumps, one for each friend on the group.
If the group is made up of 48 friends, and each exchange is done by 2 friends, you have to divide by 2 each interaction:
(48 friends * 47 first bumps) / 2 friends = (2256 friends per first bumps exchanged) / 2 friends = 1128 fist bumps exchanged.

Which value of r indicates a stronger correlation: r equals=0.828 or r equals= −0.879? explain your reasoning?
A value of r = 0.828 indicates a stronger positive correlation, while r = -0.879 indicates a stronger negative correlation.
Explanation:A stronger correlation is indicated by a value closer to 1 or -1. In this case, r = 0.828 indicates a stronger positive correlation, whereas r = -0.879 indicates a stronger negative correlation. The closer the absolute value of r is to 1, the stronger the correlation. A value of r = 0.828 suggests a strong positive relationship between two variables, while a value of r = -0.879 suggests a strong negative relationship.

One side of a rectangle is 18 inches and the other side is x inches. What values of x will make the perimeter more than 56 inches?
Line v passes through point (6, 6) and is perpendicular to the graph of y = 34x – 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
Answer:
y = -1/34 . x + 167/17
Step-by-step explanation:
The slope-intercept form of a linear equation is:
y = m.x + b
where,
m is the slope
b is the y-intercept
Line v is perpendicular to the graph of y = 34 x - 11. If 2 lines are perpendicular, the slope of one is the inverse and opposite of the other. Then, the slope of v is -1/34.
Line w is parallel to line v. When 2 lines are parallel, they have the same slope.
The equation of w is:
y = -1/34 . x + b
Lines b passes through the point (-6, 10). We can replace this ordered pair in the previous equation to find the value of b.
10 = -1/34 . (-6) + b
b = 167/17
The equation of w is:
y = -1/34 . x + 167/17

What does it mean to say that a shape has an area of 8 square inches?
Final answer:
To say a shape has an area of 8 square inches means the shape covers 8 units of square inches. For similar shapes, the area comparison is the square of their scale factor; hence, if one shape's dimensions are twice another's, its area is four times larger.
Explanation:
When it is said that a shape has an area of 8 square inches, it means that the surface enclosed by the shape covers 8 units of square inches. In other words, you could fit 8 squares, each measuring 1 inch by 1 inch, inside the shape without overlapping or leaving any space inside the shape uncovered. To understand how the area of similar shapes compares, we can look into the problem involving two squares.
Marta has one square with a side length of 4 inches. A similar square has dimensions that are twice as large, meaning its side lengths are 8 inches. The area of the smaller square can be calculated as 4 inches x 4 inches, which equals 16 square inches. The area of the larger square would be 8 inches x 8 inches, resulting in 64 square inches. The ratio comparing the two areas is 64:16, which simplifies down to 4:1. This shows that the larger square's area is four times greater than that of the smaller square.
An area of 8 square inches means the shape covers a space equivalent to eight 1-inch by 1-inch squares.
To say that a shape has an area of 8 square inches means that the amount of space enclosed within the boundaries of the shape is equivalent to the area of eight 1-inch by 1-inch squares. Imagine a piece of graph paper where each small square is 1 inch by 1 inch.If the shape could be perfectly copied onto the graph paper, you would find that it covers eight of those squares.For example, an area of 8 square inches could be visualized by a variety of shapes: a rectangle measuring 2 inches by 4 inches or even an irregular shape that neatly fits inside the same area.In mathematics, there are various ways to calculate the area depending on the shape. For regular shapes like rectangles and circles, formulas are often used. But the fundamental idea of area — the measure of the space inside a shape — remains the same.Compare and contrast the absolute value of a real number to that of a complex number
Answer:

Mrs. Santos is buying binders for the students in her class. She determined that 15 binders would cost $22.50.If all of the binders cost the same amount, which statement is true?
It will cost $12 for 18 binders.
It will cost $20 for 30 binders.
It will cost $42 for 28 binders.
It will cost $48 for 48 binders.
Answer:
Option C It will cost $42 for 28 binders
Step-by-step explanation:
Mrs. Santos determined that 15 binders would cost = $22.50
Therefore, 1 binder would cost = $1.50
Now we calculate each statement :
a. 18 binders will cost $12
= 18 × $1.50 = $27.00 (not correct)
b. 30 binders will cost $20
= 30 × $1.50 = $60.00 (not correct)
c. 28 binders will cost $42
28 × $1.50 = $42.00 (Correct)
d. 48 binders will cost $48
48 × $1.50 = $72.00 (not correct)
Option C It will cost $42 for 28 binders would be correct.
One half of a number y is more than 22
Answer:
Inequality: [tex]\frac{y}{2}>22[/tex]
Solution: [tex]y>44[/tex]
Step-by-step explanation:
We are supposed to write and solve an inequality for the given verbal description.
One half of a number y would be y divided by 2: [tex]\frac{y}{2}[/tex].
Since one half of a number y is more than 22, so we can set an inequality as:
[tex]\frac{y}{2}>22[/tex]
Multiply both sides by 2:
[tex]\frac{y}{2}*2>22*2[/tex]
[tex]y>44[/tex]
Therefore, the solution to our given inequality is any value of y greater than 44.

Jacqueline leaves city a at 2:00 p.m. and drives at a constant speed, traveling west on i-90. she passes city b, 40 mi from city a, at 2:50 p.m. (a) find a linear function d that models the distance (in mi) she has traveled after t min.
Jacqueline's speed is 0.8 miles per minute. The linear function representing the distance she has traveled in t minutes is d(t) = 0.8t. This equation means Jacqueline would have covered 0.8t miles after any given time t.
Explanation:The subject of this question is a linear function in mathematics, more specifically, it is about the concept of speed and distance. The question describes the journey of a person named Jacqueline who is traveling at a constant speed.
Given that city B is 40 miles from city A and it took Jacqueline 50 minutes to cover that distance, we can easily calculate her speed. Speed = Distance / Time. Therefore, her speed is 40 miles / 50 minutes = 0.8 miles per minute.
The linear function d, which models the distance she has traveled after t minutes would, therefore, be d(t) = 0.8t. The coefficient 0.8 indicates the speed, and the variable t is the time spent traveling. So, after any given number of minutes t, Jacqueline would have covered 0.8t miles on her journey.

what inequality represents the verbal expression? 8 less than a number n is less than 11
The inequality representing the verbal expression '8 less than a number n is less than 11' is written as 'n < 19'. This is found by adding 8 to both sides of the inequality 'n - 8 < 11'.
Explanation:The inequality that represents the verbal expression '8 less than a number n is less than 11' can be translated into a mathematical inequality as follows. First, '8 less than a number n' means you take 8 away from n, which is written as n - 8. Then, this quantity being 'less than 11' is represented by the inequality n - 8 < 11. To find the range of values for n, we solve this inequality.
Step 1: Add 8 to both sides of the inequality to isolate n -
n - 8 + 8 < 11 + 8
Step 2: Simplify -
n < 19
Therefore, the inequality symbol that represents the verbal expression is n < 19.
The inequality that represents the verbal expression '8 less than a number n is less than 11' is 8 < n < 11. The symbol '<' represents 'less than' and since the number n is between 8 and 11, we use the inequality symbol '<' twice.
The inequality that represents the verbal expression '8 less than a number n is less than 11' is 11 > n - 8 > 8.
Explanation:The inequality that represents the verbal expression '8 less than a number n is less than 11' is 11 > n - 8 > 8. This inequality states that the number n, decreased by 8, is greater than 8 and less than 11.
