Which number line shows the correct placement of 20%, 1/3, and 2/3?

Answer:

8x^{4}-2/3x^{2}-2/3x

Step-by-step explanation:

The probability of rolling double threes with two number cubes is calculated by multiplying the likelihood of each die showing a three independently, which is 1/6. Since each die is independent, the combined probability is 1/6 x 1/6 or 1/36.

When rolling two number cubes, often referred to as dice, the probability of rolling double threes is determined by considering the likelihood of each event occurring independently. Each die has six faces, so the probability of rolling a three-on-one die is 1/6. Since the outcome of rolling the second die is independent of the outcome of the first die, its probability of showing three is also 1/6.

The combined probability of both independent events occurring—that is, rolling a three on both dice—is found by multiplying the probabilities of the individual events. This means the probability is 1/6 multiplied by 1/6, which equals 1/36. So, the chance of rolling double threes is 1/36.

If we were discussing a different combination, such as rolling a one and a three, we would add the probability of the first die rolling a one and the second a three to the probability of the first die rolling a three and the second a one. But in the case of double threes, there is only one possible outcome that meets the criteria (a three on the first die and a three on the second) and therefore only one product of probabilities to consider.

1. How many hours do you spend on studying on Saturday?

2.How many hours do you spend on playing game on Saturday?

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

Statistical questions means that when you ask, you expect to have the variety of answers. Because each person will give different answer.

Two statistical questions that Evan could have asked to get his results are;

1. How many hours do you spend on studying on Saturday?

2.How many hours do you spend on playing game on Saturday?

Evan could not have asked a non-statistical question to get his results because there is only on answer and you expect the same answer from everyone you ask.

For ex: how many students spend 3 hours studying, the answer is only one, it is 2 in  Evan survey.

Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.

Step-by-step explanation:

A line plot is a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data.

The main difference between a line plot and a line graph is that the line plot shows the frequency of number within a set, and the line graph shows the value of one variable relative to another.The number of dots  in a line plot will be equal to the number of data points.

Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.

Step-by-step explanation:

Percent change can be found using:

difference between the values/original value

Difference:

The difference between 71 and 80

80-71=9

Percent Change:

difference/original

The difference is 9, and the original is 71

9/71= 0.12676056338

Convert to a percent by multiplying by 100

0.12676056338*100=12.676056338

Round the nearest hundreth: 12.68

About 12.68% increase

Answer:

12.67 percent

Step-by-step explanation:

To calculate percent change you use the following formula:

[tex]\frac{b - a}{|a|} * 100[/tex]

a = 71 (The first value)

b = 80 (The second value)

Plug the values into the formula.

[tex]\frac{80 - 71}{|71|} * 100[/tex]

[tex]\frac{9}{|71|} * 100[/tex]

[tex]0.1267 * 100[/tex]

[tex]12.67[/tex]

The percent change is 12.67 percent.

Answer:

A =  [- 2Bl + U^2 +/- √((2BL - U^2)^2 - 4B^2L^2) ] / 2L

Step-by-step explanation:

L = U^2A  / (A + B)^2

U^2 A = L(A^2 + 2AB + B^2)

U^2 A = LA^2 + 2ABL + B^2L

LA^2 + 2ABL - U^2A + B^2 L = 0

LA^2 + (2BL - U^2)A + B^2L = 0

Using the quadratic formula

A =  [- (2BL - U^2) +/- √[(2BL - U^2)^2 - 4*L*B^2L] / 2L

A =  [- 2BL + U^2 +/- √[(2BL - U^2)^2 - 4B^2L^2) ] / 2L

Answer:

The solution to this system of equations is x = -3 and y = 4.

Step-by-step explanation:

In order to solve this system we will use the second equation, which have the "y" isolated on the left side and use that value for "y" in the first equation. This is shown bellow:

5x + 4(1 - x) = 1

5x + 4 - 4x = 1

5x - 4x = 1 - 4

x = -3

Now we can use the value we found for x in the second equation to determine y.

y = 1 - x

y = 1 - (-3) = 1 + 3

y = 4

So the solution to this system of equations is x = -3 and y = 4.

Answer:

[tex]\frac{a^{2} }{10}[/tex]

Step-by-step explanation:

5*10 = 50. 50 = 25+25. The sqrt of 25 is 5, so 2 5's make 10.

The calculation of the product  [tex]a^2/5(10)[/tex] involves squaring the base 'a', then dividing by 5 and finally, multiplying by 10. The solution will depend on the given value of 'a'.

The question is asking for the product of [tex]a^2/5(10),[/tex] neglecting any typos. Here, we are assuming that the exponent 'a' in  [tex]'a^2[/tex]' is the base, which is usually a positive integer. Using the given values, the expression becomes:

[tex]10 \times (a^2 / 5)[/tex]

To simplify this expression, we first square the base 'a'. If for example, 'a' is equal to 5 (the square of 5 is 25), the expression can be rewritten as:

10 * (25 / 5)

The final calculation becomes: 10 * 5 equaling 50 as the final answer. Please note that this example is strictly for illustrative purposes and the solution will vary according to the provided value of 'a'. The concept underlying the problem is exponentiation, multiplication, and division.

Final answer:

Mosi's monthly pay rate, calculated from his annual net salary of $52,000 and divided by 12 months, is $4,333 when rounded to the nearest dollar.

Explanation:

To calculate Mosi's monthly pay rate from his annual net salary, we need to divide his total annual net income by the number of months in a year. Since Mosi's annual net salary is $52,000, we perform the following calculation:

Monthly Pay Rate = Annual Net Salary ÷ Number of months in a year

Monthly Pay Rate = $52,000 ÷ 12

The result is a monthly pay rate of $4,333.33. However, the question asks us to round to the nearest dollar. Therefore, Mosi's monthly pay rate is $4,333 when rounded to the nearest dollar.

Answer:

(2,3)

Step-by-step explanation:

Substitute y = 2x - 1 in the equation y = 5x - 7

2x - 1 = 5x - 7

2x  - 1 + 7 = 5x

2x + 6 = 5x

6 = 5x - 2x

6 = 3x

3x = 6

x = 6/3

x = 2

Substitute the value of x in, y = 2x - 1

y = 2*2 - 1

y= 4 - 1

y = 3

Answer:

1.    0.83 = 83%

2.    6.1% = 0.061

Step-by-step explanation:

The answer in number one is because when you're trying to find a percentage from a decimal, all you have to do is multiply your decimal by 100, this is because a percentage is always out of 100.

The answer in number two is exactly the opposite, all you have to do is divide by 100 if you are trying to find your decimal from a percentage.

The decimal number 0.83 is equivalent to 83% when expressed as a percentage, and the percentage 6.1% can be written as 0.061 when converted into a decimal.

To transform a decimal to a percentage, you need to multiply the decimal by 100. So, the statement 'The large tanks made up 0.83 of their sales last quarter' can be rewritten as 'The large tanks made up 83% of their sales last quarter'.

In order to transform a percentage into a decimal, you divide the percentage by 100. Therefore, the statement 'The kicker attempted 6.1% of the field goals he tried during away games' can be rewritten as 'The kicker attempted 0.061 of the field goals he tried during away games'.

Hope it will help u...

Presumably we're being asked to solve the system.  

4x - 7y = 15

5x - 2y = 12

We don't really have any common factors among the coefficients of x, or among the coefficients of y, so we can do the general thing. To eliminate y multiply the first equation by (typically the absolute value of) the coefficient of y in the second equation and vice verse, then add or subtract equations to eliminate.  

First equation times 2:

8x - 14y = 30

Second equation times 7:

35x - 14y = 84

Subtract,

27x = 54

x = 54/27 = 2

2y = 5x - 12 = 10 - 12 = -2

y = -1

Answer: x=2, y = -1

Check:

4(2)-7(-1)=8+7=15, good

5(2) -2(-1) = 10 + 2 = 12, good

If you do enough of these 2x2 linear systems you can learn to just write down the answer.  I usually remember the matrix inverse, but if you haven't gotten there you can just remember the pattern:  

ax + by = c    

dx + ey = f

has solutions

x = (ce-bf)/(ae-bd), y = (a f-cd)/(ae-bd)

4x - 7y = 15    

5x - 2y = 12

has solutions

denom = ae-bd = 4(-2) - (-7)(5) = 27

x = (15(-2) - (-7)(12))/27 = (-30 + 84)/27 = 2

y = (4(12)-15(5))/27 = (48-75)/27 = -27/27 = -1

Answer:

Step-by-step explanation:

4x-7y=15                          

Add '-7y' to each side of the equation.    

Add '2y' to each side of the equation.

5x + -2y + 2y = 12 + 2y

Combine like terms: -2y + 2y = 0

5x + 0 = 12 + 2y

5x = 12 + 2y

Divide each side by '5'.

x = 2.4 + 0.4y

Simplifying

x = 2.4 + 0.4y

4x + 7y + -7y = 15 + -7y

Combine like terms: 7y + -7y = 0

4x + 0 = 15 + -7y

4x = 15 + -7y

Answer: B

Step-by-step explanation:

To find the remainder when Marsha divides a+b by 35, substitute the values of a and b into the expression and simplify to find that the remainder is 163.

To find the remainder when Marsha divides a + b by 35, we need to consider the individual remainders when a is divided by 70 and b is divided by 105. Since Marsha gets a remainder of 64 when dividing a by 70, we can say that a = 70n + 64, where n is a positive integer. Similarly, since Marsha gets a remainder of 99 when dividing b by 105, we can say that b = 105m + 99, where m is a positive integer.

Now, substitute the values of a and b into the expression a + b and simplify:

a + b = (70n + 64) + (105m + 99) = 70n + 105m + 163

Now, divide a + b by 35 to find the remainder. Since both 70 and 105 are divisible by 35, we can simplify the expression further:

a + b = 35(2n + 3m) + 163

The remainder when dividing a + b by 35 is therefore 163.
