Reason:
6 black out of 4+6+5 = 15 total
6/15 = 0.40 is the experimental probability of selecting black.
Side note: The term "empirical probability" is the same as "experimental probability".
The experimental probability of selecting a black marble will be 0.40. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.
Number of favourable outcomes = 6
Number of samples = 4+6+5 = 15
Probability = Number of favourable outcomes / Number of samples
Probability = 6 / 15
Probability = 0.40
Therefore, the probability will be 0.40.

Find the ratio of y/x to determine if the table represents a proportional relationship:
Answers
Answer:
From the table, find the ratio between each value of y and its corresponding value of x. y/x = 1/5 = 1/5 y/x = 8/40 = 1/5 y/x = 13/65 = 1/5 So, the ratio between the values of y and and their corresponding values of x is constant. Hence, the relationship represented by the table given above is proportional.

well, the total is "x", which oddly enough is the 100%.
now, we know that 18.9% of "x" is 43100, what the dickens is "x"?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 43100& 18.9 \end{array} \implies \cfrac{x}{43100}~~=~~\cfrac{100}{18.9} \\\\\\ 18.9x=4310000\implies x=\cfrac{4310000}{18.9}\implies x\approx 228042[/tex]
The whole decimal is 2,280.42328
You have to divide 43,100 by 18.9

solve the equation for y: y + 7 = 5/4 (x + 16)
Answers
To solve the equation for y, we need to get y by itself on one side of the equation.
The first step is to get rid of the fraction on the right side of the equation by multiplying both sides by 4:
4y + 28 = x + 16
Then, we need to move the x term to the left side of the equation by subtracting x from both sides:
4y + 28 - x = 16
Then, we need to move the constant term 28 to the left side of the equation by subtracting 28 from both sides:
4y - x = -12
Finally, we have the equation in the form y = (1/4)x - 3, so the solution for y is y = (1/4)x - 3
It is important to note that in this solution we have used the distributive property and followed the order of operations to get to the final result, if you don't follow this steps you might get a different result.
STEPS FOR SOLVING LINEAR EQUATIONy+7=45(x+16)Use the distributive property to multiply 45 by x+16.y+7=45x+20Swap sides so that all variable terms are on the left hand side.45x+20=y+7Subtract 20 from both sides.45x=y+7−20Subtract 20 from 7 to get −13.45x=y−13Divide both sides of the equation by 45, which is the same as multiplying both sides by the reciprocal of the fraction.4545x=45y−13Dividing by 45 undoes the multiplication by 45.x=45y−13Divide y−13 by 45 by multiplying y−13 by the reciprocal of 45.x=54y−52SOLVE FOR Yy=45x+13

(2n²•n³•3n¹)²
First, simplify inside the parentheses. We multiply the coefficients and exponents. The coefficients: 2×3=6. and the exponents: 2×3×1=6. All together that gives: [tex](6n^6)^2[/tex]Then multiply the inside of the parentheses by itself since it's the exponent is 2. Therefore we end with [tex]36n^12[/tex]
(y•4y²)³
Same approach. Multiply the inside which gives [tex]4y^3[/tex] Then calculate that to the power of 3.
[tex]4y^3[/tex]×[tex]4y^3[/tex]×[tex]4y^3[/tex]=[tex]64y^9\\[/tex]

Answers
Answer:
The area of the circle that has a radius of 23 yards will be 1,661.06 square yards.
What is the area of the circle?
It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is 23 yards. Then the area of the circle is calculated as,
A = π x (23)²
Simplify the equation, then the area of the circle is calculated as,
A = π x (23)²
A = 3.14 x 529
A = 1,661.06 square yards
The area of the circle that has a radius of 23 yards will be 1,661.1 square yards.
