A bag contains 10 counters. 6 of them are white. a counter is taken at random and not replaced. A second counter is taken out of the bag at random. Calculate the probability that only one of the two counters are white.
PLEASE HELP!!
Step-by-step explanation:
Given:
There are 10 counters.
6 of the counters are white.
Two counters are drawn one after another without replacement.
To Find:
The probability that only one of the two counters is white
Explanation:
P(Only one of the two counters is white)
= P(white) x P( not white) + P(not white) x p(white)
Solution:
P(Only one of the two counters is white) = 6/10 x 4/9 + 4/10 x 6/9
P(Only one of the two counters is white) = 4/15 + 4/15
P(Only one of the two counters is white) = 8/15
Answer: The probability is 8/15
The probability that only one of the two counters is white will be [tex]8\div15[/tex] and this can be determined by using the probability formula.
Given :
A bag contains 10 counters, 6 of them are white. The counter is taken at random and not replaced.The probability that only one of the counters is white will be:
[tex]\rm =(probability\; of \;white\; counter) \times (probability\; of\; not \;a\; white \;counter) + (probability \;of\; not\; white\;p counter )\times (probability\; of\; white \;counter)[/tex]
[tex]= \left(\dfrac{6}{10}\times \dfrac{4}{9}\right)+\left (\dfrac{4}{10}\times \dfrac{6}{9}\right )[/tex]
[tex]= \left(\dfrac{12}{45}\right)+\left (\dfrac{4}{15}\right )[/tex]
[tex]=\dfrac{8}{15}[/tex]
Therefore, the probability that only one of the two counters is white will be[tex]8\div15[/tex].

Proof by mathematical induction
Answer:
See below.
Step-by-step explanation:
I will assume that 3n is the last term.
First let n = k, then:
Sum ( k terms) = 7k^2 + 3k
Now, the sum of k+1 terms = 7k^2 + 3k + (k+1) th term
= 7k^2 + 3k + 14(k + 1) - 4
= 7k^2 + 17k + 10
Now 7(k + 1)^2 = 7k^2 +14 k + 7 so
7k^2 + 17k + 10
= 7(k + 1)^2 + 3k + 3
= 7(k + 1)^2 + 3(k + 1)
Which is the formula for the Sum of k terms with the k replaced by k + 1.
Therefore we can say if the sum formula is true for k terms then it is also true for (k + 1) terms.
But the formula is true for 1 term because 7(1)^2 + 3(1) = 10 .
So it must also be true for all subsequent( 2,3 etc) terms.
This completes the proof.
Inductive reasoning can include making generalizations based on specific instances, such as predicting that water freezes at 32°F based on past observations. The binomial theorem, a series expansion, is an example that can be proven using mathematical induction.
Explanation:Understanding Inductive Reasoning
Inductive reasoning is a method of reasoning in which the premises seek to supply strong evidence for the truth of the conclusion.
While the conclusion of a deductive argument is certain, the truth of the conclusion of an inductive argument is probable, based upon the evidence given.
This form of reasoning allows us to create generalizations based on observations or patterns we have seen.
For instance, when we see that water freezes at 32° Fahrenheit, and we observe a temperature drop to 30°F at night, we can induce that there will be ice in the morning.
Mathematical Induction
Mathematical induction is a specific type of inductive reasoning that is used for proving that a statement is true for all natural numbers. It is a two-step process where we first prove that a base case is true, typically for n=1.
Then, we show that if the statement is true for an arbitrary positive integer n, this implies that it's also true for n+1.
This creates a domino effect, proving the initial statement for all natural numbers.
The binomial theorem is a classic example of series expansion that can be proven using mathematical induction.
The theorem expands powers of binomials in a form that involves summation of terms, and each term is a product of binomial coefficients and the variables raised to appropriate powers.
Series Expansions and Inductive Inferences
Series expansions in mathematics, such as the binomial theorem, are formulated based on patterns observed in specific instances.
These patterns are then generalized to hold for all numbers within the constraints of the theorem. In contrast, weak inductive inferences are those which cannot firmly establish a conclusion due to insufficient or irrelevant evidence.

6= a/4 +2
two step equations
Answer:
a=16
Step-by-step explanation:
We want to take the 6 on the left side of the equal sign and do the equation in the reverse.
First since we are adding 2, we want to substract 2 away from 6.
6-2 = 4
Then, since we are dividing by 4, we want to multiply by 4.
4*4 = 16
We can check this to make sure it's correct by replacing a with 16:
16/4 = 4
4+2 = 6
The solution of the expression is,
⇒ a = 16
We have to given that;
Expression is,
⇒ 6 = 2 + a/4
Now, WE can simplify as;
⇒ 6 = 2 + a/4
⇒ 6 - 2 = a/4
⇒ 4 = a/4
⇒ a / 4 = 4
⇒ a = 4 × 4
⇒ a = 16
Thus, The solution of the expression is,
⇒ a = 16

The following equation describes a circle.
2x^2 - 20x + 2y^2 + 8y =40
What are the center and radius of the circle?
Based on the given equation of the circle, the center of the circle is (5, -2), and the radius is 7.
How to determine the center and radius of the circle
To determine the center and radius of the circle described by the equation rewrite the equation in the standard form of a circle equation, which is
[tex](x - h)^2 + (y - k)^2 = r^2.[/tex]
First, complete the square for both the x and y terms:
[tex]2x^2 - 20x + 2y^2 + 8y = 40[/tex]
To complete the square for the x-terms, factor out a 2 from the [tex]x^2[/tex] and x terms:
[tex]2(x^2 - 10x) + 2y^2 + 8y = 40[/tex]
Now, add and subtract the square of half the coefficient of x, which is [tex](-10/2)^2[/tex] = 25:
[tex]2(x^2 - 10x + 25 - 25) + 2y^2 + 8y = 40[/tex]
Simplifying inside the parentheses:
[tex]2((x - 5)^2 - 25) + 2y^2 + 8y = 40[/tex]
Similarly, for the y-terms, add and subtract the square of half the coefficient of y, which is
[tex](8/2)^2[/tex] = 16:
[tex]2((x - 5)^2 - 25) + 2(y^2 + 4y + 4 - 4) = 40[/tex]
Simplifying inside the parentheses:
Now, let's distribute the 2 on both terms:
[tex]2(x - 5)^2 - 50 + 2(y + 2)^2 - 8 = 40\\2(x - 5)^2 + 2(y + 2)^2 - 58 = 40[/tex]
Rearrange the equation:
[tex]2(x - 5)^2 + 2(y + 2)^2 = 98[/tex]
Divide both sides by 2 to simplify:
[tex](x - 5)^2 + (y + 2)^2 = 49[/tex]
Now the equation is in the standard form of a circle equation.
Comparing it to [tex](x - h)^2 + (y - k)^2 = r^2[/tex], we can see that the center of the circle is (h, k) = (5, -2), and the radius squared is r^2 = 49.
Take the square root of both sides
r = 7.
Therefore, the center of the circle is (5, -2), and the radius is 7.

Two hundred people attended the history museum exhibit on Monday. Twenty-five of the people who attended the exhibit were surveyed at random. Twelve of the surveyed people answered "yes" to the question.
How many of the total number of people who attended the history museum would you expect to answer "yes"?
12
24
48
96
Answer:
96
Step-by-step explanation:
Total number of people attending the history museum is 200
Surveyed people are 25
Out of the 25, 12 people said yes
Therefore; the fraction which said yes = 12/25
To find the total number of people expected to say yes out of those that attended the history museum;
Fraction of the sampled that said yes × total number of people that attended.
= 12/25 × 200
= 96
A 128 ounce container of orange juice cost $5.12 at the local supermarket. What price should the supermarket sell 96 ounce container of orange juice so that the unit rate of the container is the same?
Answer:
Step-by-step explanation:
To figure out the unit rate, divide 5.12 by 128. You should get 0.04, which is the unit rate or cost per ounce. To figure out how much the 96 oz can should be, multiply $0.04 times 96.
Your answer should be $3.84.
Final answer:
To maintain the same unit rate as the 128 ounce container of orange juice that costs $5.12, the supermarket should price the 96 ounce container at $3.84.
Explanation:
The student is asking how to calculate the price for a 96 ounce container of orange juice, given that a 128 ounce container costs $5.12, with the condition that the unit rate remains the same. First, we need to determine the unit rate for the orange juice in the 128 ounce container. To do that, divide the total cost by the number of ounces to find the cost per ounce:
$5.12 \/ 128 ext{ounces} = $0.04 ext{per ounce}
Now that we have the unit rate ($0.04 per ounce), we can calculate the cost for a 96 ounce container by multiplying the unit rate by the number of ounces:
96 ext{ounces} \times $0.04 ext{per ounce} = $3.84
Therefore, the supermarket should sell the 96 ounce container of orange juice for $3.84 to keep the unit rate the same as the 128 ounce container.

Point P (1, 7) is located on circle C. The center of circle C is (-2, 3). What is the radius of the circle?
Answer:
Radius = 5 units
Step-by-step explanation:
We can use the formula of getting magnitude of a line joining two points;
(x1, y1) and (x2, y2)
Length = √((x2-x1)² + (y2-y1)²)
Therefore;
In this case the radius will be; PC
Length of PC = √((3-7)² + (-2-1)²)
= √((-4)² + (-3)²)
= √(16 +9)
= √ 25
= 5 units
Thus the radius is 5 units

Answer: I think its C but im not positive!
Step-by-step explanation:
Answer:
Option D. is the correct option
Step-by-step explanation:
The graph of g(x) is the translation of y = ∛x, which passes through origin (0, 0).
The graph in the figure is showing a shift of 1.5 units downwards.
Therefore, the new translated function g(x) will be represented by
g(x) = ∛x - 1.5
This graph can create a confusion of being shifted on x-axis but when we plug in the values of x in the options A and B, parent graph gets changed.
Therefore, option D. is the answer.

Name the quadrilaterals that have four equal angles. A. rhombus, square B. Square, rectangle C. parallelogram, rhombus D. rhombus, trapezoid
Answer:
B. Square, Rectangle.
Step-by-step explanation:
The correct answer is B. Square, Rectangle.
A square will always have four equal angles and sides.
A rectangle will not have equal sides, but will always have angles of 90 degrees, as does the square.
Hope this helps!
Final answer:
Quadrilaterals with four equal angles are rectangles and squares since they both have four right angles. The correct answer is B: Square, Rectangle.
Explanation:
The question asks us to name the quadrilaterals that have four equal angles. A quadrilateral is a polygon with four sides and four angles. When all the angles in a quadrilateral are equal, they have to be right angles (each measuring 90°) since the sum of all angles in any quadrilateral is 360°. Thus, the types of quadrilaterals with four right angles are:
Rectangle: All four angles are right angles, and opposite sides are equal.
Square: It has all the properties of a rectangle but with the added feature that all four sides are also equal.
Therefore, the rectangles and squares are the quadrilaterals that have four equal angles.
A rhombus has four equal sides, but the angles are not necessarily right angles. A parallelogram has opposite angles that are equal, which does not guarantee that all four angles are equal unless it's a rectangle. Trapezoids generally do not have four equal angles. Therefore, the correct answer to the question is option B: Square, Rectangle.
