Answer:
Range.
Step-by-step explanation:
Alan must use the measure called Range, which indicates the dispersion between the extreme values of a variable. It is calculated as the difference between the highest and the lowest value of the variable. It is denoted as R. First the data is sorted, then it is calculated as:
R = x (n) - x (1) where,
x (n): It is the largest value of the variable.
x (1): It is the smallest value of the variable.
In the given case (5, 6, 7, 5, 7, 9, 2, 4, 8, and 7), we sort the data, and get,
2, 4, 5, 5, 6, 7, 7, 7, 8, 9
x (n) = 9
X (1) = 2
R = 9 - 2 = 7

A spinner has 6 parts numbered 1–6. If the result is 1 or 6, a player wins the number times $10.00. On the other hand, if the result is 2–5, then the player loses the number times $5. What can you say about this game?
The probability of winning is higher than that of losing.
The probabilities of winning and losing are equal.
The probability of losing is higher than that of winning.
There is not sufficient information about the game.
2 numbers win
4 numbers lose
so answer would be The probability of losing is higher than that of winning.
Answer:
Option C
Step-by-step explanation:
We are given that a spinner has 6 parts numbered 1-6.
If the result is 1 or 6 then a player wins the number times $10.00.If the result is 2-5 then the player loses the number times $5.
Number of cases when the player wins number times $10.00=1 or 6=2
Number of cases when the player loses the number times $5=2,3,4,5=4
Total number of cases =6
Formula for finding probability
P(E)=[tex]\frac{Number \;of\; favourable\; cases}{Total \; number\; of \; cases}[/tex]
Applying this formula
The probability of wining=[tex]\frac{2}{6}[/tex]
The probability of wining=[tex]\frac{1}{3}[/tex]
The probability of wining=0.33
The probability of losing=[tex]\frac{4}{6}[/tex]
The probability of losing=[tex]\frac{2}{3}[/tex]
The probability of losing=0.66
Hence, the probability of losing is higher than that of winning.
Therefore, option C is true.
Which description matches the graph of the inequality y ≥ |x + 2| – 3? a shaded region above a solid boundary line a shaded region below a solid boundary line a shaded region below a dashed boundary line a shaded region above a dashed boundary line
Final answer:
The graph of the inequality y ≥ |x + 2| − 3 is represented by a shaded region above a solid V-shaped boundary line that has its vertex at the point (-2, -3).
Explanation:
To determine which description matches the graph of the inequality y ≥ |x + 2| − 3, it is essential to understand the properties of the inequality and the properties of absolute value functions. The absolute value function |x + 2| creates a V-shaped graph with a vertex at the point (-2, 0). When this is adjusted by subtracting 3, the vertex of the V shape is moved down to (-2, -3).
The inequality sign ≥ indicates that we are looking for the region that includes all y-values that are greater than or equal to the function |x + 2| − 3. Therefore, the region of the graph that we are interested in is above this V-shaped graph. The equal part of the inequality ≥ allows us to use a solid boundary line rather than a dashed line, because the points on the graph of y = |x + 2| − 3 are included in the solutions for the inequality.
So, the correct description is a shaded region above a solid boundary line, which represents all the points (x, y) where y is greater than or equal to the value of |x + 2| minus 3.

The Smiths want to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room.
If the Smith's want to use square tiles, which are 6 inch on each side, in the area not covered by the carpet, how many tiles will they need?
Answer:
Correct answer is 768 tiles.
The Smiths would need 768 tiles to cover the area not occupied by the carpet in their 15 ft by 20 ft room.
Explanation:To solve this problem, let's first understand the dimensions. The room is 15 ft by 20 ft which gives a total space of 300 ft2. The carpet is 9 ft by 12 ft, so it will cover an area of 108 ft2.
We subtract the area of the carpet from the total area of the room to find the area that needs to be covered with tiles: 300 ft2 - 108 ft2 = 192 ft2.
Each square tile measures 6 inches by 6 inches. We must convert this to feet, as our other measurements are in feet. So, each tile is 0.5 ft by 0.5 ft, giving an area of 0.25 ft2 per tile.
Finally, we divide the total tile area needed (192 ft2) by the area of each tile (0.25 ft2). This gives us: 192 ÷ 0.25 = 768 tiles.

The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.03x2 + 1.53x, where x is the horizontal distance in yards and y is the corresponding height in yards. What is the football’s maximum height? Round to the nearest tenth. yds. How far is the football kicked? yds.
Answer:
Maximum height achieved by football = 25.5 yards.
Distance traveled by football 51 yards.
Step-by-step explanation:
Path of a football kicked by a field goal kicker can be modeled by the equation y = -0.03x² + 1.53x.
Where x represents horizontal distance and y represents height of the football.
For maximum, height we will find the [tex]\frac{dy}{dx}[/tex] ( derivative ) of the equation and equate it to zero.
[tex]\frac{d(y)}{dx}[/tex] = [tex]\frac{d}{dx}[/tex] (-0.03x² + 1.53x )
[tex]\frac{dy}{dx}[/tex] = -0.03 × 2x + 1.53
By putting [tex]\frac{dy}{dx}[/tex] = 0
-0.06x + 1.53 = 0
0.06x = 1.53
x = [tex]\frac{1.53}{0.06}[/tex] = 25.5 yards
Therefore, maximum height achieved by the ball is 25.5 yards.
Now for horizontal distance covered by ball y should be 0
-0.03x² + 1.53x = 0
x ( 1.53 - 0.03x ) = 0
0.03x = 1.53
x = [tex]\frac{1.53}{0.03}[/tex] = 51 yards.
Football was kicked 51 yards.
0.3x + 5.14 = 2.1x - 4.4
The value of x = 5.3.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The equation is,
0.3x +5.14 = 2.1x -4.4
The equation here formed is made of two expressions,
Expression 1: 0.3x +5.14 and,
Expression 2 : 2.1x -4.4
In the expressions, the variable is x, and the constants are 0.3, 5.14, 2.1, -4.4
Solving for x,
0.3x +5.14 = 2.1x -4.4
Taking variable on the left side, and the constants on the right side.
Taking the like terms on one side,
0.3x - 2.1x = -4.4 -5.14
The negative sign gets cancelled,
-1.8x = -9.54
Dividing 1.8 on both sides.
x = (-9.54 / -1.8)
x = 5.3
The value of x is 5.3.

At what point on the curve y=sqrt(1+2x) is the tangent line perpendicular to the line 6x+2y=1
The required point of tangency if the curve y=sqrt(1+2x) is the tangent line perpendicular to the line 6x+2y=1 is (4, 3)
Given the curve expressed as y = √1+2x
Also, given the equation 6x + 2y = 1
Get the slope of the line
6x + 2y = 1
2y = -6x + 1
y = -3x + 1
The slope of the line is -3
The slope of the line perpendicular will be 1/3
The equation of the tangent line perpendicular to the line 6x+2y=1, hence;
y = 1/3 x + b
Equate the equation with the equation of the curve;
√1+2x = 1/3 x + b
Square both sides
(√1+2x)² = (1/3 x + b)²
1 + 2x = 1/9x² + 2/3bx + b²
Multiply through by 9
9 + 18x = x² + 6bx + 9b²
x²+ 6bx-18x-9+9b² = 0
x²+(6b-18)x-(9-9b²) = 0
x²+(6b-18)x+9b²-9 = 0
If the discriminant b²-4ac = 0, hence;
(6b-18)² - 4(9b²-9) = 0
36b² - 216b + 324 - 36b²+36 = 0
- 216b + 360 = 0
216b = 360
b = 360/216
b = 5/3
Get the value of x by substituting b = 5/3 into x²+(6b-18)x+9b²-9 = 0
x² + [6(5/3) - 18]x + [9(5/3)² - 9] = 0
x² - [10 - 18]x + [9(25/9)- 9] = 0
x² + 8x + [25- 9] = 0
x² + 8x + 16 = 0
x² + 4x + 4x + 16 = 0
(x - 4)² = 0
x = 4
Substitute x = 4 into the y value
y = √(1 + 2(4))
y = √9
y = 3
Hence the required coordinate is (4, 3)
