Both Tetsuya and Mason are interested in finding the probability that a red marble will be chosen out of the bag. We will decide if either of them is correct.
In statistics, what does a probability mean?
The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.Tetsuya P( R) = 4/17
Mason P( R ) = 1 - 4/18
P ( R) = Favorable outcome/ possible outcome
The number of favorable outcomes is the number of red marbles in the bag, so it is equal to 4. The number of possible outcomes is the number of all marbles in the bag. Let's find it.
4 + 7 + 5 + 2 = 18
We have enough information to find the probability that a red marble will be chosen P(R).
P( R) = 4/18
Tetsuya used the wrong number of possible outcomes in the denominator. Let's look at Mason's solution. They wanted to use the probability of complementary events. However, they found the probability that a selected marble is not red.
Mason P( R ) = 1 - 4/18

What is the length of the hypotenuse of a 45°-45°-90° triangle if the leg length is 6 centimeters?
The length of the hypotenuse of a 45°-45°- 90° triangle with a leg length of 6 centimeters is 8.49 approximately.
To find the hypotenuse of 45°-45°-90° triangle:
The formula to calculate the hypotenuse of 45°-45°-90° triangle is to multiply the length of the leg by [tex]\sqrt{2}[/tex].
How to find the length of the hypotenuse?
The length of the two legs of 45°-45°-90° triangle is equal.
Then the length of its hypotenuse will be calculated by multiplying the length of the leg and [tex]\sqrt{2}[/tex] .
Since the length of the leg is 6 centimeters,
Then its hypotenuse will be:
h = 6 × [tex]\sqrt{2}[/tex]
h = 8.485
h ≈ 8.49
So, the length of the hypotenuse will be 8.49.

What is the least common denominator of 3/4 and 15/16
The least common denominator of 3/4 and 15/16 is 16.
What is Least Common Denominator?When two or more fractions are given, the least common denominator is the smallest number of all common multiples of the denominators. To find the least common denominator, list the multiples of both denominators until you find the smallest multiple shared by both. Because 28 is the first shared multiple of 4 and 7, it must be the least common denominator of these two fractions.So, LCD od 3/4 and 15/16:
3/4 × 4/4 = 12/1615/16 × 1/1 = 15/16Now, the denominator of both the fractions is the same which is 16.

The general form of a linear equation is y - y1 = m(x - x1) then the point-slope form exists y - 5 = 3(x - 9)
What is point-slope form?The general structure of a linear equation exists y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that exists not the y-intercept).
Given: (x1, y1) = (9, 5) and (x2, y2) = (8, 2)
The point-slope form exists given by,
y - y1 = m(x - x1)
m = (y2 - y1)/(x2 - x1)
substitute the values in the above equation, we get
m = (2 - 5)/(8 - 9)
m = 3
The value of m = 3.
y - 5 = 3(x - 9)

Do invariant points sometimes, always, or never occur in a rotation? Explain your reasoning.
Points that map onto themselves are said to be invariant points. Invariant points can occasionally appear during a rotation.
Do rotations have invariant points?
The axis of rotation is a line of invariant points that defines the rotation of a three-dimensional figure in space. Since rotation does not alter the shape of the figure being rotated, it is referred to as an isometric transformation along with translation and reflection.Points that map onto themselves are said to be invariant points. Invariant points can occasionally appear during a rotation.
The point of rotation is invariant when a figure is rotated about that point. There are no invariant points in a rotation of a figure centered on a point that is not on the figure.

Answer:
Step-by-step explanatio -3/8d-1 3/8
The expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or (-3 1/4d + 3/5) - (2 7/8d + 7/10) is equivalent to "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.
An algebraic expression is a number, variable, or the combination of both and operational symbols.
To determine the equivalent of the expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or simply (-3 1/4d + 3/5) - (2 7/8d + 7/10), combine all like terms and perform the necessary operations.
(-3 1/4d + 3/5) - (2 7/8d + 7/10)
⇒ -3 1/4d + 3/5 - 2 7/8d - 7/10
⇒ (-3 1/4 - 2 7/8)d + 3/5 - 7/10
⇒ (-13/4 - 23/8)d + 6/10 - 7/10
⇒ (-26/8 - 23/8)d - 1/10
⇒ -49/8 d - 1/10

while high negative x (x going to -infinity) would create high negative y (also -infinity), x⁵ with its odd exponent is negative for negative x and positive for positive x.
the graph is showing just the opposite behavior.
so, it cannot be the right graph.
b)
the degree of the polynomial is the highest exponent of the input variable x. in our case : 5
a polynomial of degree n must have n zeros (or roots).
in our case we need 5 zeros. but there are only 3. no matter how we shift it up or down, the x-axis will not intercept it more than 3 times.

COORDINATE GEOMETRY Find the distance from P to l .Line l contains points (0,-2) and (1,3) . Point P has coordinates (-4,4) .
According to the given statement the perpendicular distance form the point (-4,4) is 66.3.
What Exactly Is Coordinate Geometry?Coordinate Geometry can be used to define points in space. The primary axis labeled a x- and y-axes is defined first, and then the points were measured and labelled in relation to these points. Furthermore, numerous geometric forms such as a line, curve, circle, ellipse, and hyperbola can be plotted inside the coordinate axes and their attributes studied.
According to the given data:the equation for line ℓ.
Begin by finding the slope of the line through the given points,(0,-2) and (1,3):
m = (Y₂ - Y₁)/(x₂ - x₁)
= (3 - (-2))/(1 - 0)
= 5/1
= 5
The equation of the line using point (1,3) on the line:
Y - Y₁ = m(x - x₁)
putting value we get: (m = 5)
Y - (-2) = 5(x - 1)
Y + 2 = 5x - 5
Y = 5x - 3
The equation of the line w perpendicular to line ℓ through P(-4,4).
The slop of line l is 5. Write the equation of the line using point P(-4,4) on the line.
Y - Y₁ = m(x - x₁)
Y - 4 = 5(x - (-4))
Y - 4 = 5x + 4
Y = 5x + 8
Solve the system of equations to determine the point of intersection. Subtract both sides of (1) and (2) to eliminate y.
5x + 8 = 5x - 3
5x + 8 - 5x + 3 = 0
x = 11
putting the value of x to find y:
Y = 5x + 8
Y = 62
Applying the formula to find the distance of a points:'
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
d = √((11 - 4 )² + (62 + 4)²)
d = √(4405)
d = 66.3
According to the given statement the perpendicular distance form the point (-4,4) is 66.3.

What is the volume of the cuboid?The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.
The volume of a cuboid is length × breadth× height
As it is 3D geometry
The volume will be L×W×H i.e. 50×25×2 = 2500 m³
Since one cubic meter is equal to 264.172052 gallons,
So 2500 m³ = 264.17 × 2500 = 660425 gallons
If the water bill is equivalent to $1 per 1000 gallons
So 660425/1000 = 660.425
Hence, there will be 660.425 dollars cost to fill up the pool.
