12-[2 + 6 ÷ (10 - 2³)]

Answer:

Step-by-step explanation: total number of counters = 10

number of red counters= 3

number of blue counters= 2

number of green counters = 5

p(of getting a red counter) =3/10

p(of not getting a red counter) = 1-3/10= 10-3/10=7/10

Answer:

The probability that one marble drawn at random is not blue is 70%

\(f'(x) = (7x^{2} - 3x + 2)^{ \frac{7}{2}} (14x - 3)\)

Formula :

\( \boxed{f(x) = u^{n} \: \rightarrow \: f'(x) = n \times u^{n - 1} \times u'}\)

Step by step :

\( \begin{aligned}f(x)&=(7x^{2} - 3x + 2)^{\frac{9}{2}}\\f'(x)&= \frac{9}{2}(7x^{2} - 3x + 2)^{ \frac{9 - 2}{2}} (14x - 3) \\& = \frac{9}{2} (7x^{2} - 3x + 2)^{ \frac{7}{2}} (14x - 3)\end{aligned}\)

8-5+43/8

43 divided by 8 is 5.375.

The answer I got was 8.375

A one-to-one correspondence between the set of all positive integers and the set of all rational numbers exists.

By definition, any rational number can be expressed as a fraction a/b, where a and b are integers and b is nonzero. Since any positive integer can be expressed as the fraction a/1, each positive integer can be associated with a rational number a/1.

Thus, there is a one-to-one correspondence between the set of all positive integers and the set of all rational numbers. Furthermore, since any rational number a/b can be expressed as the product of a and b, it can also be associated with the product of two positive integers a and b.

Thus, there is also a one-to-one correspondence between the set of all rational numbers and the set of all positive integers.

the answer is C.because it is a suitable combination for the question

The baseball team will have won 42 games, and lost 42 games

This is put simply, because 7 is half of 14, and so the total games won and lost will be half.

For example:
14 - 7 = 7

Which then can be used to interpret the answer as half of the total.

In this instance:
84 - 42 = 42

Answer:

  x ≈ 2.09590327429

Step-by-step explanation:

You want the solution to 3^x = 10 using logarithms.

Taking logarithms of both sides of the given equation, we have ...

  x·log(3) = log(10)

Dividing by the coefficient of x gives ...

  x = log(10)/log(3)

  x ≈ 2.09590327429

__

Additional comment

If the logarithm to the base 10 is used, then this becomes ...

  x = 1/log₁₀(3)

The meaning of "log( )" varies with the context. In high-school algebra, it usually means "log₁₀( )". In other contexts, it may mean "ln( )", the natural logarithm.

For the purpose here, it doesn't matter what base the logarithms have, as long as log(10) and log(3) are to the same base.

<95141404393>

The approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.

To evaluate the equation 3^x = 10 using logarithms, we can take the logarithm of both sides of the equation. The most commonly used logarithm is the base 10 logarithm, also known as the common logarithm (log).

Taking the log of both sides, we get:

log(3^x) = log(10)

Now, we can apply the logarithmic property that states log(a^b) = b * log(a). Applying this property to the left side of the equation:

x * log(3) = log(10)

Next, we can divide both sides of the equation by log(3) to isolate the variable x:

x = log(10) / log(3)

Using a calculator, we can evaluate the right side of the equation:

x ≈ 1.46497

Therefore, the approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.

As the number of degrees of freedom for t-distribution increases, the difference between the t-distribution and standard deviation becomes smaller. The correct answer is B.

A t-distribution is described by one parameter, that is, degrees of freedom (df) v = n – 1, where n is the sample size. Its variance = v, where v represents the number of degrees of freedom and v ≥ 2.

To calculate degrees of freedom of a 1-sample t-test, we have to determine the size of our sample (N). Then, subtract 1. The result is the number of degrees of freedom.

The biased question is C. "Do you feel that the TV news is a sensational portrayal of life’s problems?" because it contains a value judgment ("sensational portrayal") that may lead the respondent to answer in a particular way. It suggests that the TV news is overly dramatic or exaggerated in its coverage of issues, which may not be a belief held by all respondents. The other questions (A, B, and D) do not contain value judgments and are more straightforward in nature.

The height of the plant, the time Anthony plants the seed and the number of months, analyzed using an assumption of a constant growth rate indicates;

PT1.A; 1 5/8 inches

PT2.B; 4 1/8 inches per month

A growth rate is the rate at which the a quantity being measured increases per unit time.

The height of the plant at the beginning of the summer in June = 12 3/8 inches

Height of the plant at the end of the summer in September = 14 inches

PT1.A. The amount by which the plant grows is therefore;

14 - 12 3/8 = 14 - 99/8 = (112 - 99)/8 = 13/8

13/8 = 1 5/8

The length in inches by which the plant had grown from June to September = 1 5/8 inches

PT2.B. The amount by which the plant had grown per month, can be found by assuming a linear relationship in the growth rate of the plant

The number of months between March and June = 6 - 3 = 3 months

The growth rate of the plant per month is therefore;

Growth rate = (12 3/8)/3 = (99/8)/3 = 33/8

33/8 = 4 1/8

The growth rate of the plant = 4 1/8 inches per month

Answer:

Huh.

Step-by-step explanation:

Subtracting 1 from -1 does not equal 2.

When you subtract 1 from -1, you're essentially calculating -1 - 1, which results in -2.

To clarify, subtraction is an arithmetic operation where you take away a number from another number to find the difference between them. In this case, subtracting 1 from -1 gives you a result of -2, not 2.

Answer:

1- (-1 = 2

1 + 1 = 2

Step-by-step explanation:

when there is subtract after 1 we have to put bracket then again subtract we cannot write subtract two times we have two put bracket and when there is bracket we have to multiply - and - and minus minus is plus thus 1 + 1 = 2

Answer:

Starting with the equation:

(x + 1)^2 = 13/4

We can use the square root property, which states that if a^2 = b, then a is equal to the positive or negative square root of b.

Taking the square root of both sides, we get:

x + 1 = ±√(13/4)

Simplifying under the radical:

x + 1 = ±(√13)/2

Now we can solve for x by subtracting 1 from both sides:

x = -1 ± (√13)/2

Therefore, the solutions to the equation are:

x = -1 + (√13)/2 or x = -1 - (√13)/2

Answer:

x = 3/2 or x = -1

Step-by-step explanation:

2x² - x - 3 = 0

2*(-3) = -6

Factors of -6:

(-1, 6), (1, -6), (-2, 3), (2, -3)

We need to find a pair that adds up to the co-eff of x which is (-1)

Factors :(2,-3)

2 - 3 = -1

so, 2x² - x - 3 = 0 can be written as:

2x² + 2x - 3x - 3 = 0

⇒ 2x(x + 1) -3(x + 1) = 0

⇒ (2x - 3)(x + 1) = 0

⇒ 2x - 3 = 0 or

x + 1 = 0

⇒ 2x = 3 or x = -1

⇒ x = 3/2 or x = -1

Answer:

  94.3

Step-by-step explanation:

You want to know how to fill in the proportion associated with the question, "What is 115% of 82?"

The diagram is intended to help you match parts of the question to parts of the proportion. The attachment shows the intended relation.

The solution is found by multiplying both sides by 82:

  (x/82)·82 = (115/100)·82

  x = 94.3

The question can also be written as a statement:

  "what" is 115% of 82

When written as an equation, "is" means "equals", and "of" means "times":

  what = 115% × 82

Of course, you can use any variable name of your choosing in place of "what". In your diagram, that is "x". And, you know how to write a percentage as a fraction or decimal, so this becomes ...

  x = 115/100 × 82 = 1.15 × 82

All that remains is to evaluate this expression.

  x = 1.15 × 82 = 94.3

So, the answer to the question is ...

  94.3 is 115% of 82.

The median is 6.5

Step-by-step explanation:

To find the median, first organize the numbers from least to greatest:

1, 4, 6, 6, 7, 8, 9, 10

The median is always the number in the middle, but since there are eight numbers here, there will be two numbers in the middle: 6 and 7.

To solve for this, we have to find the average of the numbers.

Add the two numbers together and then divide by 2 (we divide by 2 because we are averaging two numbers).
