The probability of getting a black ball is 5/13, if odds of choosing one black ball fron urn are 5 to 8.

According to the given question.

The odds of choosing one black ball from an urn are 5 to 8.

As we know that "the odds for an event is the ratio of the favorable outcomes to the unfavorable outcomes".

Therefore,

The favorable outcomes of getting black ball = 5

Unfavorable outcomes of getting black ball = 8

So, total outcomes = 5 + 8 = 13

Thereofre,

The probability of getting a black ball

= favorable outcomes/ total number of outcomes

= 5/13

Hence, the probability of getting a black ball is 5/13.

Answer:

D : 1 1/2

Step-by-step explanation:

150% converted into a decimal is 1.5, this is the same as 1 1/2, so the answer is D.

hope this helps :)

The 150% as a fraction in simplest form is D. 1 1/2

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have to write 150% as a fraction in simplest form.

So we put 150 over 100

That is (150/100)

Now multiply the top and the bottom by 10 to get rid of the decimal  as;

15/10

1.5 = 1 1/2

Hence, the fraction in simplest form is 1 1/2

Answer:

y = (1/15)x (+ 0) [The y-intercept is 0]: y = (1/15)x

Step-by-step explanation:

The standard slope/intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).

We are given a slope of (1/15) so we can write:

y = (1/15)x + b

The given point (0,0) just so happens to have the information for b, the y-intercept. b id the value of y when x=0. Point (0,0) tells us that the value of y when x=0 is 0 (aor at least will be when we develop the equation. So b = 0, and we progress to:

y= (1/15)x + 0

This is the equation in slope-intercept form.

Answer:

15 times of \(\frac{1}{5}\) go into 3.

Step-by-step explanation:

Consider the provided information.

How many times will \(\frac{1}{5}\) go into 3?

First setup the problem in numerical form.

Let x denote the required number of times.

Then, according to the given information, we have

x × \(\frac{1}{5}\) = 3

⇒ x = 3 × 5 = 15

Thus, 15 times of \(\frac{1}{5}\) go into 3.

The ordered pair (3, 3) satisfies both equations simultaneously, and hence it is the solution to the system of equations represented by the Graph.

The system of equations represented by the graph is 2x - 3y = 9 and -x + 4y = 12.

The graph contains two lines that intersect at a point, which is the solution to the system of equations.What is a System of Equations?A system of equations is a set of two or more equations that are to be solved simultaneously. These equations have the same variables.

If the system has two equations, it is called a system of two linear equations in two variables. The variables represent two unknown quantities, and the equations represent the relationships between them.Graphical Representation of a System of EquationsThe graphical representation of a system of equations is done by plotting the lines that are represented by the equations on the same coordinate plane.

If the two lines intersect at a point, then that point is the solution to the system of equations.The solution to the system of equations is the ordered pair that satisfies both equations simultaneously. This means that if we substitute the values of the ordered pair into both equations, the equations will be true.

The Solution to the System of Equations represented by the GraphThe graph of the system of equations given in the question contains two lines that intersect at a point. The point of intersection is (3, 3).

Therefore, the solution to the system of equations is (3, 3).Now we can verify that the ordered pair (3, 3) is the solution to both equations. When we substitute x = 3 and y = 3 in the first equation, we get:2x - 3y = 9 ⇒ 2(3) - 3(3) = 9 ⇒ 6 - 9 = -3This equation is true. Now we can substitute x = 3 and y = 3 in the second equation, we get:-x + 4y = 12 ⇒ -(3) + 4(3) = 12 ⇒ -3 + 12 = 9

This equation is also true.

Therefore, the ordered pair (3, 3) satisfies both equations simultaneously, and hence it is the solution to the system of equations represented by the graph.

Rounding to the nearest whole value, we get the estimated number of observations above 118 as 2940.

To determine the number of observations expected to be below a certain value using the 68-95-99.7 Rule, we need to find the area under the normal distribution curve up to that value.

For the first scenario:

Mean (μ) = 162

Standard deviation (σ) = 11

Value to evaluate (x) = 195

We want to find the area under the curve to the left of x = 195. This corresponds to the cumulative probability of a value being less than 195 in a normal distribution.

Using a standard normal distribution table or a calculator, we can find that the cumulative probability for x = 195 is approximately 0.961. This means that about 96.1% of the observations are expected to be below 195.

To find the number of observations, we multiply the cumulative probability by the total number of observations:

Number of observations = 0.961 * 2400 = 2306.4

Rounding to the nearest single observation, we get the estimated number of observations below 195 as 2306.

For the second scenario:

Mean (μ) = 137

Standard deviation (σ) = 19

Value to evaluate (x) = 118

We want to find the area under the curve to the right of x = 118. This corresponds to the cumulative probability of a value being greater than 118 in a normal distribution.

Using the same approach, we can find that the cumulative probability for x = 118 is approximately 0.735. This means that about 73.5% of the observations are expected to be above 118.

To find the number of observations, we multiply the cumulative probability by the total number of observations:

Number of observations = 0.735 * 4000 = 2940

Step-by-step explanation:

The numbers are 15 and 9 .

Numbers are the basic foundation of mathematics. Numbers are used to represent quantity and used is basic arithmetic operations. Numbers can be categorized into a lot of different types such as real  or imaginary. Real numbers can be divided into integers , irrational numbers , whole numbers .The four basic arithmetic operations are multiplication , sum , division and subtraction.

Let us consider one of the given numbers be x .

Given the sum of the numbers is 21

therefore the other number = 21 - x

Now it is given that  \(\frac{3}{4}\) of 1 number and \(\frac{2}{3}\) of another number adds up to 15 .

∴ \(\frac{3}{4}\) of x =  \(\frac{3}{4}x\)  and  \(\frac{2}{3}\) of another number =  \(\frac{2}{3}\times(21-x)\)

Now the sum of the two new numbers is given as 15.

∴ \(\frac{2}{3}\times(21-x) +\frac{3}{4}x =15\)

\(or, 14-\frac{2}{3}x +\frac{3}{4}x =15\\\\or, -\frac{2}{3}x +\frac{3}{4}x =15-14\\\\or, \frac{-8+9}{12} x=1\\\\or, \frac{1}{12}x = 1\\\\or, x=12\)

So the other number is 21-12 = 9 .

Hence the two numbers are 15 and 9 .

Answer:

The possible dimensions are;

If Rectangle B has a dimension of 1 unit x 2 units, then Rectangle A has a dimension of 0.315 units x 12.685 units

Step-by-step explanation:

Let;

Length of Rectangle A be a

Width of Rectangle A be b

Length of Rectangle B be c

Width of Rectangle B be d

Thus;

Area of Rectangle A = a × b

Area of Rectangle B = c × d

We are told that the area of Rectangle A is twice the area of Rectangle B:

Thus;

2cd = ab - - - - - eq. 1

perimeter of Rectangle A = 2a + 2b

perimeter of Rectangle B = 2c + 2d

We are told that the perimeter of Rectangle A is 20 units greater than the perimeter of Rectangle B. Thus, we now have;

20 + 2c + 2d = 2a + 2b - - - - eq. 2

We have 4 unknowns which are (a, b, c and d) but only 2 equations, so we need to reduce to 2 unknown variables and calculate the other ones. In this way, one of the infinite solutions is obtained.

Let's assume that c = 1 and d = 2, we obtain:

From eq 1, we have;

2 * 1 * 2 = a*b

ab = 4 or a = 4/b

From eq 2, we have;

20 + 2(1) + 2(2) = 2a + 2b

26 = 2a + 2b

Putting a = 4/b into this, we have;

26 = 2(4/b) + 2b

Multiply through by b to get;

26b = 8 + 2b²

So,we have;

2b² -26b + 8 = 0

Using quadratic formula for this,

b = 0.315 or 12.685

When, b = 12.685, a = 4/12.685 = 0.315

When, b = 0.315, a = 4/0.315 = 12.685

So, the possible dimensions are;

If Rectangle B has a dimension of 1 unit x 2 units, then Rectangle A has a dimension of 0.315 units x 12.685 units

Therefore, by using a representative sample and appropriate statistical methods, it is possible to estimate the difference in expected muscle mass for women whose ages differ by one year without knowing the specific ages of the individuals in the population.

It is not necessary to know the specific ages of women to estimate the difference in expected muscle mass for women whose ages differ by one year because the confidence interval is based on a population-level estimate rather than individual-specific data.

In this case, the confidence interval is constructed based on a sample of women, which provides an estimate of the average difference in expected muscle mass for women whose ages differ by one year in the population. The sample is selected randomly and is assumed to be representative of the population of interest.

By using statistical techniques, such as hypothesis testing and confidence interval estimation, we can make inferences about population parameters, such as the difference in muscle mass for women of different ages. These techniques rely on the assumption that the sample is representative of the population, rather than requiring specific individual-level information.

To eliminate the x variable, you should multiply the equation by -(coefficient of x in the second equation)/(coefficient of x in the first equation)

One way of solving systems of linear equations is by using the method of elimination. This method involves adding or subtracting a multiple of one equation to the other in order to eliminate one of the variables.

In order to eliminate one of the variables, you should multiply the first equation by a coefficient that will make one of the variables in the first equation the opposite of the corresponding variable in the second equation when they are added.

For example, if you want to eliminate the variable x, you should multiply the first equation by a coefficient that makes the coefficient of x in the first equation the opposite of the coefficient of x in the second equation.

So if the equation is y = mx + b, to eliminate the x variable, you should multiply the equation by -(coefficient of x in the second equation)/(coefficient of x in the first equation).

It's important to note that you should be careful when choosing the coefficient, you should make sure that you don't divide by zero.

Step-by-step explanation:

The 5 positive integers are 3,3,4,4,16, for them mode is 3 and 4, a median is  4 and mean is 6.

The median is a middle number of sequence, more precisely when the series is shorted descending to ascending order the middle term is median.

Let the number 3 repeats m times,

The number 4 repeats n times,

and any other number is x,

Mean of series is 6, therefore,

(3m+4n+x)/5 = 6

3m+4n +x = 30

Since, mode of 5 number is 3 and 4

So, the value of m can be 2 and value of n can also be 2,

3(2) + 4(2) + x = 30

x = 30-14

x = 16
