As a Decimal:
0.4MABUHAY!The probability of Spencer picking a black marble is approximately 0.4 or 40%.
To find the probability of Spencer picking a black marble, we can use the formula for probability:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
In this case, the number of favorable outcomes (picking a black marble) is 4, as there are 4 black marbles in the bag. The total number of possible outcomes (picking any marble) is 10, as there are 10 marbles in total.
Now, we can calculate the probability:
Probability = 4 / 10
Simplifying the fraction, we get:
Probability = 2 / 5
To express the probability as a decimal, divide the numerator (2) by the denominator (5):
Probability = 2 ÷ 5
Probability ≈ 0.4
The probability represents the likelihood of an event occurring, and in this case, it tells us the chance of Spencer picking a black marble out of the 10 marbles in the bag.

Answer:
C
Step-by-step explanation:
Data Set I is multiplicative because
x y
------------
0×2 = 0
1×2 = 2
2×2 = 4
etc.
Data Set II is additive because
x y
--------------
0+2 = 2
1+2 = 3
2+2 = 4
etc.
Answer: C
Step-by-step explanation: Hi there.
To answer this question, we need to look closely at the data tables and answers.
A cannot be right. If the relationship is additive, that means that an input x is being added to a number to get a certain number y. If the relationship is multiplicative, that means an input x is being multiplied by number to get a certain number y. The relationship cannot be additive if the input is being multiplied (and vice versa) because it does not make sense.
B cannot be right. (See A for reason)
D cannot be right. (See A for reason)
C is right. It states that Data Set I is multiplicative because y is 2 times x, and the relationship for Data Set II is additive because y is two more than x. Every x value in Data Set I is being multiplied by 2 to get y (just divide y by 2 to check), and every x value in Data Set II has 2 added to it to get y (just subtract y by 2 to check). It also gets it right that Data Set I is multiplicative and Data Set II is additive.

1) Simplify the expression. –2x(1–3x) + (2x + 3)(3x – 2)
Make sure you show all your work for full credit. Use standard polynomial format.
Answer:
12x² + 3x - 6
Step-by-step explanation: -2x(1-3x) = -2x+6x²
(2x+3)(3x-2), first do 2x
2x × 3x = 6x²
then 2x × -2= -4x
we then move to the number 3
3 × 3x = 9x
3 × -2 = -6
after that we add them together
-2x + 6x² + 6x² - 4x +9x - 6 = 6x² + 6x² is 12x², -2x - 4x + 9x = 3x, and then -6 is by its self
= 12x² + 3x - 6
The simplified solution of the expression is 6x²- 4x - 6.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, and/or operators that can be evaluated to obtain a value. Expressions can be as simple as a single variable or number, or as complex as a combination of variables, numbers, and mathematical operations.
We can simplify the expression by distributing the terms and combining like terms:
E = -2x(1 - 3x) + (2x + 3)(3x - 2)
E = -2x + 6x² + (6x - 4x - 6)
E = 6x² - 4x - 6
Therefore, the simplified expression is 6x²- 4x - 6.

Ralph plotted the points (-4, 3) and (-4, -3) on a coordinate grid. What is the distance, in units, between the points Ralph plotted?
Enter your numerical answer in the box, do not include words or spaces.
Answer:
6 units
Step-by-step explanation:
Given the following question:
Point A = (-4, 3) = (x, y)
Point B = (-4, -3) = (x, y)
To find the distance between the following points we must first plot the points on the coordinate plane.
Point A: Move over to the left four times, move up three times.
Point B: Move over to the left four times, move down three times.
The distance between the two points given is "six units." Since the x values are the same, and the y values are opposites from each other doubling their distance by two.
Hope this helps.

Convert the angle - 3 radians to degrees, rounding to the nearest 10th.
Answer:
formula :
-3rad × 180/π = -171.9°
Step-by-step explanation:
hope that help's you :))!!
The measure of the angle in degrees is A = -171.9°
What is Central Angle?The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
where s is the length of the arc
r is the radius of the circle
Central Angle = 2 x Angle in other segment
Given data ,
Let the measure of the angle be A = -3°
Now , angle in degrees = angle in radians × 180°/π
Substituting the given value, we get:
The angle in degrees = (-3) × 180°/π
On simplifying the equation , we get
A = -171.8873385°
On rounding to the nearest tenth , we get
A = -171.9°
Hence , the angle is A = -171.9°

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Factor completely 5ax² − 20x³ + 2a − 8x.
Take 5x² common from the first two terms and 2 from the last two terms. we have
5ax² − 20x³ + 2a − 8x
5x²(a − 4x) + 2 (a − 4x)
Take (a - 4) common, then we have
(5x² + 2) (y − 4x)
The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.
