The total score of Joseph for four days of the tournament is -4 .
Joseph had the following scores for a four-day tournament,
For the first day i.e., day 1 of the tournament the total score is -1 . For the second day i.e., day 2 of the tournament the total score is 2 . For the third day i.e., day 3 of the tournament the total score is -2 . For the fourth day i.e., day 2 of the tournament the total score is -3 .
To calculate the total score of four days of the tournament we need to add the score of first, second, third and fourth day.
The total score of four days of the tournament = ( -1 ) + ( 2 ) + ( -2 ) + ( -3 )
The total score of four days of the tournament = -4

From calculating the percentages we can say that 43 more students went on Friday than Saturday.
Percentage is defined as quantity per hundred. Percentage is calculated by dividing the given number by the total number and multiplying it by 100.
From the survey we can see that 550 students were supposed to go on Friday. But it is given that 18 percent students did not go to the festival.
Number of students who went = 550 - (18% of 550 )
Therefore students = 550 - 99 =451 students
Again from the survey we can see that 480 students were supposed to go on Saturday . But it is given that 15 percent students did not go to the festival.
Number of students who went =480 - (15% of 480 )
Therefore students = 480 - 72 = 408 students
Therefore the number of more students who went on Friday than Saturday is 451-408 = 43 students

Answer:
1) Constant
2) Decreasing
3) Increasing
Step-by-step explanation:
1) Graphically, we can say that a function is constant if we see a flat line, which means that the range is the same throughout its domain, in this case we have one flat line, therefore it is a constant function
2) The graph is going down as it moves from left to right in all the domain, that means it's decreasing
3) The graph is going up as it moves from left to right in all the domain, that means it's increasing.
- Find BC if B(8, -7) and C(-4, -2).
The line segment BC has a length of 13 units.
What is the length of a line segment?
In this question we know the locations of the two ends of a line segment. The procedure consists in calculating the vector behind the line segment and later determing its magnitude by Pythagorean theorem. If we know that B(x, y) = (8, - 7) and C(x, y) = (- 4, - 2), then the length of the line segment BC is:
BC = (- 4, - 2) - (8, - 7)
BC = (- 12, 5)
BC = √[(- 12)² + 5²]
BC = 13

A square pyramid has a base with a side length of 6 meters. If the
slant height of the pyramid is 5 meters, what is the surface area of the
pyramid?
m²
Answer:
96
Step-by-step explanation:
?
The surface area of the square pyramid with length of the base 6m and slant height of the pyramid 5m is 96 m².
A square pyramid is a 3-D geometrical figure with the base of the shape of square and four triangular faces from each side of the square joining together at the top to form vertex.
The surface area of a square pyramid is given as:
Base area of the square face + 1/2 (perimeter of base × slant height)
Since square base has side of length 6m and the slant height of the pyramid is 5m then surface area is given by;
Surface area = (6×6) + 1/2 (4×6×5)
=> 36 + 1/2 (120)
=> 36 + 60
=> 96 m²
Thus, surface area of square pyramid is 96 m².

61/100 is the equivalent fraction for the given decimal number.
A decimal number then has two components: a whole number part and a fractional part. The decimal place value system for the whole part of a decimal number is the same as the whole number value system. However, we get the fractional part of the decimal number as we move toward the right after the decimal point.
A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken. The number below the line is called the denominator. It shows the total number of equal parts the whole is divided into or the total number of the same objects in a collection.
for converting a decimal into a fraction we need to multiply and divide the decimal by the 10^n where n is the number of digits after the decimal.

when constructing a congruent line segment does the ray needed for the construation have to be shorter than the line segment
The condition for two line segments to be congruent is that they must have equal length.
What is a line segment?
A geometrical figure which is a part of a straight line having two unique endpoints is called a line segment. Each point on the line segment lies within the two given endpoints
Explanation of the fact that for the two given line segments to be congruent, they must have the same length
The given statement is False. Because two line segments are said to be congruent if and only if they have exactly the same length. If we construct a ray shorter than the line segment, then both will never be congruent according to the properties of congruence. So, for these two to become congruent, they must have the same length.
Hence, we obtain that the two line segments are congruent if they have exactly the same length.

3(z - 1) - 1/2 (4z + 10) = 4 (z - 3/2) + 10
Answer:
z = -4
Step-by-step explanation:
Let's solve the problem,
→ 3(z - 1) - 1/2 (4z + 10) = 4 (z - 3/2) + 10
→ 3z - 3 - 2z - 5 = 4z - 6 + 10
→ z - 8 = 4z + 4
→ 4z - z = -4 - 8
→ 3z = -12
→ z = -12/3
→ [ z = -4 ]
Hence, the value of z is -4.
Given that 1 kilometer = 0.62 mile, 36 inches = 1 yard, and 1 mile = 1760 yards, approximately how many inches are in 1 km?
Given that 1 kilometer = 0.62 mile, 36 inches = 1 yard, and 1 mile = 1760 yards, 1 km has approximately 39,283.2 inches.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.
From the problem, the conversion factors are given as
1 kilometer = 0.62 mile
36 inches = 1 yard
1 mile = 1760 yards
To convert 1 kilometer into inches, first, convert 1 kilometer to miles using the conversion factor, 1 kilometer = 0.62 mile
1 km = 0.62 miles
Then, convert miles to yards using the conversion factor, 1 mile = 1760 yards
1 km = 0.62 miles = 0.62 (1760 yards)
1 km = 0.62 miles = 1091.2 yards
Lastly, convert yards to inches using the conversion factor, 36 inches = 1 yard
1 km = 0.62 miles = 1091.2 yards = 1091.2 (36 inches)
1 km = 0.62 miles = 1091.2 yards = 39,283.2 inches

A linear function is shown on the graph.

What is the domain of the function?
{x | 0 ≤ x ≤ 4}
{x | 0 < x < 4}
{y | 2 ≤ y ≤ 6}
{y | 2 < y < 6}
Answer:
A) {x | 0 ≤ x ≤ 4}Step-by-step explanation:
The x-coordinates form the domain.
We know the x-coordinates of the end points of the line, the first numbers in pair of coordinates:
x = 0 and x = 4Also, since both points are closed circles, the endpoints are included.
So the domain is the interval between 0 and 4, both inclusive.
This is shown as:
{x | 0 ≤ x ≤ 4}The matching answer choice is A.
The domain of the function includes all x-values from 0 to 4, including both 0 and 4.
So, the correct answer is option A: {[tex]{x | 0 \leq x \leq 4}\\[/tex]}.
The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. In this case, the function begins with a closed circle at (0, 2) and ends with a closed circle at (4, 6), which means that the function is defined at these specific points.
Since the function is a linear function, it represents a straight line.
A linear function is continuous, and it extends indefinitely in both directions.
Therefore, any x-value between 0 and 4 will also be defined by the linear function.
In mathematical notation, we can represent the domain as:
Domain: {x | 0 ≤ x ≤ 4}
This means that the domain of the function includes all x-values from 0 to 4, including both 0 and 4.
So, the correct answer is option A: {[tex]{x | 0 \leq x \leq 4}\\[/tex]}.

The correct option is r < 0 for the given inequalities of p < 0, q > 0, and p + q = r.
What is defined by the number line?You can select any point as "0," and all positive numbers will be to the right of the "0," and all negative numbers will be to the left of the "0." A line of infinite length, the points of which correspond to real numbers based on their distance in a negative or positive position from a point randomly chosen as zero.A number line is a straight line to numbers at equal intervals or sections along its length. A number line could be extended in any direction indefinitely and is typically represented horizontally.For the given inequalities;
p < 0, q > 0, and p + q = r;
As, we know that if p < 0; then it hold the negative value.
And for q > 0, it have the positive values.
Because -negative(P) was closer to zero than Positive q, let's say p = -10 and q = 5.
