Step-by-step explanation:

Arrange the numbers in order from smallest to largest:

28, 35, 40, 40, 45, 52, 54, 58, 60

Median is the middle value  = 45

Mode is the number that appears most = 40

Mean is the average. Add the numbers and divide:

412/9 = 45.77 = 45.78

Range is difference between  highest and lowest = 60 - 28 = 32

Answer:

[tex]21.5\%[/tex]

Step-by-step explanation:

we know that

The probability that a point in the square below  is in the shaded region, is equal to divide the area of the shaded region by the area of the square

step 1

Find the area of the shaded region

The area is equal to the area of the square minus the area of the circle

[tex]A=b^{2} -\pi(r)^{2}[/tex]

we have

[tex]b=12\ cm[/tex] ---> length side of the square

[tex]r=12/2=6\ cm[/tex] ----> the radius is half the diameter

assume

[tex]\pi =3.14[/tex]

substitute

[tex]A=12^{2} -(3.14)(6)^{2}[/tex]

[tex]A=30.96\ cm^{2}[/tex]

step 2

Find the area of the square

[tex]A=b^{2}[/tex]

we have

[tex]b=12\ cm[/tex] ---> length side of the square

substitute

[tex]A=12^{2}=144\ cm^{2}[/tex]

step 3

Find the probability

[tex]P=30.96/144=0.215[/tex]

Convert to percent form

[tex]0.215*100=21.5\%[/tex]

Zilch, none.

the volume of the box is the same, it simply just sideways for the sake of display.

First you must have the quadratic equal to zero. In order to do this you must subtract 7 to both sides

x^2 + 20x + (100 - 7) = 7 - 7

x^2 + 20x + 93 = 0

Now you must find two numbers who's sum equals 20 and their multiplication equal 93

Are there any? NO!

This means that you have to use the formula:

[tex]\frac{-b±\sqrt{b^{2} - 4ac} }{2a}[/tex]

In this case:

a = 1

b = 20

c = 93

[tex]\frac{-(20) plus/minus\sqrt{20^{2} - 4(1)(93)} }{2*1}[/tex]

[tex]\frac{-20 plus/minus\sqrt{400 - 372} }{2}[/tex]

[tex]\frac{-20 plus/minus\sqrt{28} }{2}[/tex]

^^^We must simplify √28

√28 = 2√7

so...

[tex]\frac{-20 plus/minus 2\sqrt{7} }{2}[/tex]

simplify further:

[tex]-10 plus/minus\sqrt{7[/tex]

-10 + √7

or

-10 - √7

***plus/minus = ±

Answer:

1/250

Step-by-step explanation:

Final answer:

To convert the recurring decimal 0.004 into a fraction, you can set up an equation by writing 0.004 = x and solve for x to find the fraction.

Explanation:

To convert the recurring decimal 0.004 into a fraction, we need to understand the concept of converting decimals to fractions. We can do this by setting up an equation where the decimal is equal to a fraction, and then solving for the fraction. In this case, we can set up the equation 0.004 = x, where x is the fraction we're trying to find. To eliminate the decimal, we can multiply both sides of the equation by 1000, which gives us 4 = 1000x. Now, we can divide both sides of the equation by 1000 to solve for x, which gives us x = 4/1000. Simplifying the fraction gives us x = 1/250. Therefore, the recurring decimal 0.004 can be written as the fraction 1/250.

look below and can i have brainlyplus                                                             Start with the original price, $80.

If you take 20% off, then you will be paying 80% of the original price. Calculate 80% of $80.

80% of $80 = 80% * $80 = 0.8 * $80 = $64

After applying the 20% discount, the new price is $64.

Now you apply the 10% coupon.

Since you are taking 10% off the discounted price, you will be paying 90% of the discounted price.

90% of $64 = 0.9 * $64 = $57.6

The final discounted price is $57.60

Answer: For Last Question 4.50

Step-by-step explanation:It depends on the price per pound. Let's say the price per pound is 50 cents (or 0.50). (This is an example, the answer I'm giving will most likely NOT be correct, due to the nature of your question - sorry!) To calculate the price of Derek's package, you would multiply 7 (the weight of the package) by 0.50 (the price per pound), which totals to 3.50 Next, to calculate the price for Keisha's package, you'd do the same thing, but instead of multiplying 7 by the price per pound, you would multiply 10 by the price per pound, or 0.50. This multiplies out to 5 dollars. Next you'd subtract Derek's price from Keisha's, which is 5 - 3.50 or 1.50. If it is asking for a percentage, it would be about 150%.

Answer:

x=-9

Step-by-step explanation:

(square root 6)^8x= 216^(x-3)

Rewriting sqrt(6) as 6^1/2

6^1/2^8x = 216^(x-3)

We know a^b^c = a^(b*c)

6^(1/2*8x) = 216^(x-3)

6^(4x) = 216^(x-3)

We know 216 = 6^3

6^(4x) = 6^3^(x-3)

We know a^b^c = a^(b*c)

6^(4x) = 6^(3*(x-3))

6^(4x) = 6^(3x-9)

Since the bases are the same, the exponents have to be the same

4x = 3x-9

Subtract 3x from each side

4x-3x =3x-3x-9

x = -9

Answer:

z = -5

Step-by-step explanation:

The LCD in this problem is 6.  Thus, we have (2/6)z = -5/6 + (1/6)z.

Combining like terms, we have (1/6)z = -5/6.

Multiplying both sides by 6 isolates z as desired:

z = -5

Answer:

m = 25/9

Step-by-step explanation:

To solve for m, we must make the equation look like m=?

Since m is divided by 54, we can multiply both sides by 54 to make it have a coefficient of 1. So now our equation looks like:

m = 5/9 * 5

So m = 25/9

Answer: The answer to your question is m=30

Step-by-step explanation: When you are trying to solve proportions, you must cross multiply. The problem will now look like this:

5/9= m/54 (original problem)

[tex]\frac{5}{9}= \frac{m}{54}[/tex]

9m=270

Divide by 9 on both sides

9m= 270/9

m=30

Therefore, the solution to the proportion is 30. Hope this helps!!!

Answer:

2.16 * (10^-5).

Step-by-step explanation:

5 = -log H+

5 = log (1 / H+)

1/ H+ = 10^5

H+ = 10^-5

In a similar fashion  the other brand has H+ of 10^-4.5.

So the difference in hydrogen ion concentration =  10^(-4.5) - 10^(-5)

= 2.16 * (10^-5).

2.16 × 10⁻⁵ is the  difference in the concentration of hydrogen ions between the two brands of vinegar.

pH is a numerical indicator of how acidic or basic aqueous and other liquid solutions are. The phrase, which is frequently used in biology, agronomy, and chemistry, converts the hydrogen ion concentration, which typically ranges between 1 and 1014 gram-equivalents per litre, into numbers ranging from 0 to 14.

The hydrogen ion concentration in pure water, which has a pH of 7, is 107 gram-equivalents per litre, making it neutral (neither acidic or alkaline). A solution having a pH below 7 is referred to as acidic, and one with a pH over 7 is referred to as basic, or alkaline.

5 = -log H+

5 = log (1 / H+)

1/ H+ = 10^5

H+ = 10^-5

difference=  10^(-4.5) - 10^(-5)

               = 2.16 × 10⁻⁵

Therefore, 2.16 × 10⁻⁵ is the  difference in the concentration of hydrogen ions between the two brands of vinegar.

ANSWER

Yes,no two ordered pairs on this graph have the same first element

EXPLANATION

For a set of ordered pairs to be a function,there must not be any two points that have the same first elements.

This means that, the x-coordinates must not repeat for any two given points.

The graph given represents a function because,no two ordered pairs on this graph have the same first element.

Hence it would pass the vertical line test.

The third choice is correct.

The correct answer is: Yes, no two ordered pairs on this graph have the same second element.

To determine if a graph represents a function, one must apply the Vertical Line Test. This test states that a graph represents a function if no vertical line intersects the graph at more than one point. In other words, for every input (x-value), there is exactly one output (y-value). This is equivalent to saying that no two ordered pairs on the graph have the same first element (x-value) and different second elements (y-values).

The statement Yes, no two ordered pairs on this graph have the same second element correctly describes the condition for a graph to represent a function. It implies that for every y-value, there is only one x-value associated with it, which is the definition of a function.

The other options are incorrect for the following reasons:

- Yes, there is more than one ordered pair on this graph. While this statement may be true, it does not address the condition necessary for a graph to represent a function. A graph with multiple ordered pairs could still fail to be a function if any vertical line intersects the graph more than once.

- Yes, no two ordered pairs on this graph have the same first element. This statement is not relevant to the definition of a function. A function can have the same x-value associated with different y-values (which would be multiple ordered pairs with the same first element). The key is that for each x-value, there can only be one y-value.

- No, there is a limited number of ordered pairs on this graph. The number of ordered pairs being limited does not affect whether the graph represents a function. A function can have a finite or infinite number of ordered pairs. The defining characteristic is that there is exactly one output for each input, not the total number of ordered pairs.

Therefore, the correct justification for the graph representing a function is that no two ordered pairs on the graph have the same second element, ensuring that the graph passes the Vertical Line Test.

[tex]-6x=-162[/tex]         divide both sides by (-6)

[tex]x=27[/tex]

Answer: Option A

Step-by-step explanation:

A relation between two variables x and y is considered a function if and only if, for each input value x there is only one output value y.

If for an input value [tex]x_0[/tex] there are two output values [tex]y_1[/tex] and [tex]y_2[/tex] then the relation is not a function.

Therefore, to answer this question, identify the table in which each value of x has only one value of y.

You may notice that the option that meets this requirement is option A

Note that in option B, there are two output values 17 and 16 for x = -4.

So this relationship is not a function.

In option C there are 2 output values for x = -5

In option D there are 2 output values for x = -11

Answer:

The angle is 50.2°.

Step-by-step explanation:

The tree and its shadow from a right triangle with the tree being the perpendicular and the shadow being the base as shown in the figure attached.

Therefore the angle θ formed by the sun's rays and the ground is:

[tex]\theta = tan^-1(\frac{18}{15} )=\boxed{50.2^o}[/tex]

The angle formed by the sun's rays and the ground can be found using trigonometry and it is approximately 50.19°

Given: length of tree is 18 ft. and the shadow of tree is 15 ft.

To find: angle formed by suns rays and the ground

This question involves using trigonometry to find the angle formed by the sun's rays and the ground. We can use the tangent function which is:

[tex]\tan \theta = \frac{\text{perpendicular}}{\text{base}}[/tex]

Here the perpendicular is the length of the tree, base is the shadow of the tree and θ is the angle formed by suns rays and ground. So, plugging the values we get:

[tex]\tan \theta = \frac{18}{15}[/tex]

We see that 15 and 18 have 3 as a common factor so we can divide the numerator and denominator by 3 to simply the fraction and we get:

[tex]\tan \theta = \frac{6}{5} = 1.2[/tex]

To find the angle, we take the inverse tangent of the ratio:

[tex]\theta = tan^{-1} (1.2)[/tex]

θ ≈ 50.19°

Thus, the angle formed by the sun's rays and the ground is approximately 50.19°.

-576° is coterminal with ±216,±144.

Therefore

cos (-576°)=cos(±216°)=cos(±144°)

The principal angle for -576° is 36° .

Since the terminal side of -576° is in the second quadrant and the cosine ratio is negative in the second quadrant,

cos (-576°)=-cos (±36°)

Also from complementary angles

cos (-576°)=-cos (36°)=-sin (90-36)=-sin(54°)

Answer:8>4n=6 or 8>4+n=6

Step-by-step explanation:

Let's solve the equation step by step. The problem statement can be translated into a mathematical equation:
"Eight more than the product of a number and 4 is equal to 6."
Let x be the number we are looking for. When the problem says "the product of a number and 4," we can express this as 4 * x or 4x. The phrase "eight more than" implies we are to add 8 to the product of the number and 4, making the expression 4x + 8. According to the statement, this expression is equal to 6. Thus, we write the equation as:
4x + 8 = 6
To find the value of x, we will follow these steps:
1. Subtract 8 from both sides of the equation to isolate the term with x on one side.
4x + 8 - 8 = 6 - 8
This simplifies to:
4x = -2
2. Divide both sides of the equation by 4 to solve for x.
4x / 4 = -2 / 4
This simplifies to:
x = -1/2
So the number we were looking for, represented as x, is -1/2.

Answer:

The amount after three years is $12831.8

Step-by-step explanation:

* Lets revise the compound interest

- The formula for compound interest is  A = P (1 + r/n)^(nt)

 Where:

# A = the value of the investment with interest

# P = the initial investment amount  

# r = the annual interest rate (decimal)

# n = the number of times that interest is compounded per unit t

# t = the time the money is invested

* Now lets solve the problem

∵ The initial amount is $9000

∴ P = $9000

∵ The rate is 12%

∴ r = 12/100 = 0.12

∵ The interest is compound quarterly

∴ n = 4

∵ The money invested for 3 years

∴ t = 3

∵ A = P (1 + r/n)^(nt)

∴ A = 9000(1 + 0.12/4)^(4×3)

∴ A = 9000(1 + 0.03)^12

∴ A = 9000(1.03)^12 = $12831.8
