The value of h(x) at x = 2 is 3.

Given that f(x) and g(x) are differentiable functions with f(2) = 5, g(2) = 3, f′(2) = 1/2, and g′(2) = 2, and the new function h(x) is defined as h(x) = 3f(x) − 4g(x), we can find h'(2) by using the derivative rules for sums and products:

h'(x) = 3f'(x) - 4g'(x)

By plugging in the given values for f'(2) and g'(2), we get:

h'(2) = 3(1/2) - 4(2) = 3/2 - 8 = -6.5

Therefore, the derivative of h(x) at x = 2 is -6.5.

To find h(2), we can plug in the given values for f(2) and g(2) into the equation for h(x):

h(2) = 3f(2) - 4g(2) = 3(5) - 4(3) = 15 - 12 = 3

In conclusion, the derivative of h(x) at x = 2 is -6.5 and the value of h(x) at x = 2 is 3.

The mean is 18.6.

Given the following information; z = 2.25, x = 22.2, and σ = 1.6, to find the mean, we have to apply the formula for z-score. z = (x - μ)/σWhere; z-score is represented by z, the value of X is represented by x, the mean is represented by μ and the standard deviation is represented by σSubstituting the values into the equation above;2.25 = (22.2 - μ)/1.6Multiplying both sides of the equation by 1.6, we have;1.6(2.25) = (22.2 - μ)3.6 = 22.2 - μ Subtracting 22.2 from both sides of the equation;3.6 - 22.2 = - μ-18.6 = - μ Multiplying both sides of the equation by -1, we have;μ = 18.6

Simply said, a z-score, also known as a standard score, informs you of how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.

You can plot a z-score on a normal distribution curve. Z-scores range from -3 standard deviations, which would fall to the extreme left of the normal distribution curve, to +3 standard deviations, which would fall to the far right. You must be aware of the mean and population standard deviation in order to use a z-score.

The z-score can show you how that person's weight compares to the mean weight of the general population.

Answer:

If it's 16, then it's -4 > x

Step-by-step explanation:

Ignore the inequality sign first and solve 12 = -3x

This would equal -4 = x

Now, when you divide or multiply both sides by a negative, you have to change the inequality sign so you change it from -4 > x to -4 < x

The probability of observing a sample mean between 84 and 86 when n = 9 is approximately 0.5878.

To calculate p(84 ≤ x ≤ 86) when n = 9, we first need to determine the distribution of the sample mean. Since the sample size is n = 9, we can use the central limit theorem to assume that the distribution of the sample mean is approximately normal with mean μ = 85 and standard deviation σ = σ/√n = σ/3, where σ is the population standard deviation.

Next, we need to standardize the values of 84 and 86 using the formula z = (x - μ) / (σ / √n). Plugging in the values, we get:

z(84) = (84 - 85) / (σ/3) = -1 / (σ/3)
z(86) = (86 - 85) / (σ/3) = 1 / (σ/3)

To calculate the probability between these two z-scores, we can use a standard normal table or a calculator with a normal distribution function. The probability can be expressed as:

P(-1/σ ≤ Z ≤ 1/σ) = Φ(1/σ) - Φ(-1/σ)

where Φ is the cumulative distribution function of the standard normal distribution.

Therefore, to calculate p(84 ≤ x ≤ 86) when n = 9, we need to determine the value of σ and use the formula above. If σ is known, we can plug in the value and calculate the probability. If σ is unknown, we need to estimate it using the sample standard deviation and replace it in the formula.

For example, if the sample standard deviation is s = 2, then σ = s * √n = 2 * √9 = 6. Plugging in this value in the formula, we get:

P(-1/6 ≤ Z ≤ 1/6) = Φ(1/6) - Φ(-1/6) = 0.2061 - 0.7939 = 0.5878

Therefore, the probability of observing a sample mean between 84 and 86 when n = 9 is approximately 0.5878.

B. x = 7; y = -1

Step-by-step explanation:

xy = -7

x + y = 6

A and D don't work since the product of xy is not -7.

Try B: x = 7; y = -1

xy = -7

(7)(-1) = -7

-7 = -7

It works on the first equation.

x + y = 6

7 + (-1) = 6

6 = 6

It works on the second equation.

Answer: B. x = 7; y = -1

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:

= x² + 3x² + 3x² - 6xy - 3xy + 4xy + 9y² - 4y² + 3x

= 7x² - 5xy + 5y² + 3x

The simplified form of the expression is 7x² - 5xy + 5y² + 3x.

Answer:

equation;

\((x + 4) {}^{2} + (y - 2) {}^{2} = 27\)

Center (-4,2)

Radius is

\(3 \sqrt{3} \)

Step-by-step explanation:

Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of

\((x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} \)

Where (h,k) is center

r is the radius

So first we group like Terms together

\( {x}^{2} + 8x + {y}^{2} - 4y - 7 = 0\)

Add 7 to both sides

\( {x}^{2} + 8x + {y}^{2} - 4y = 7\)

\(( {x}^{2} + 8x) +( {y}^{2} - 4y) = 7\)

Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem

\( (\frac{8}{2} ) {}^{2} = 16\)

and

\(( - \frac{4}{2} ) {}^{2} = 4\)

so we have

\( {x}^{2} + 8x + 16 + {y}^{2} - 4y + 4y = 7 + 16 + 4\)

\( {x}^{2} + 8x + 16 + {y}^{2} - 4y + 4y = 27\)

\((x + 4) {}^{2} + (y - 2) {}^{2} = 27\)

To find our center, h is -4 and k is 2

so the center is (-4,2)

The radius is

\( \sqrt{27} = 3 \sqrt{3} \)

So the radius is 3 times sqr root of 3.

Step-by-step explanation:

This is the standard form of a quadratic function with leading coefficient 1, and  0 and -7.

If the zeros of a quadratic function are 0 and -7, then the function can be written as:

f(x) = a(x - 0)(x - (-7))

Simplifying:

f(x) = a(x)(x + 7)

To find the value of 'a', we can use one of the points on the parabola. Since we know that the x-intercept is 0, we can substitute x = 0 and y = 0 into the equation:

0 = a(0)(0 + 7)

0 = 0

This tells us that a can be any value, as long as it's not 0. Let's choose a = 1 for simplicity. Then the quadratic function with zeros 0 and -7 is:

The associative property works with expressions that use a property of addition and multiplication that states that the way the terms are grouped in an expression does not affect the final result.

In associative property, when you add or multiply several numbers together, you can regroup them in any way you like, and the sum or product will be the same.

For example, suppose we have the expression (2 + 3) + 4. By the associative property of addition, we can regroup the terms as 2 + (3 + 4) and the result will be the same, which is 9.

The associative property also works with more elaborate expressions, such as those involving variables, exponents, and parentheses. For instance, the expression 2a(bc) can be regrouped as (2ab)c or a(2bc), and the result will be the same. Similarly, the expression (3x)^2 y can be written as 9x^2 y, or as 3x (3xy), and the result will still be the same.
