As the test's p-value above the 0.05 level of significance, we cannot reject the hypothesis.

X=97.77 is the mean on the PDI.

a )

The population standard deviation of the PDI:S = 14-69

The PDI sample size is n=70.

The test statistic value is

=X -μ/б-√n

97.77 - 100/14.69√70

Z = - 1.27

The test's p-value is 1.

Value of p = 2p (z - 1.27).

=2 ( = NORMSDIST (-1.27) )

= - 2 (0.1020 )

p-value = 0.2041

Since , the p -value of the test is greater the the 0.05 level of significance, so we fail to reject hypothesis

The per capita income is the ratio of the total income to the population

The per capita income of the county is $30150.75

The given parameters are:

Population = 159.2 thousand

Land area = 1,536.7 square miles

Total income = $4.8 billion

The per capita income is then calculated as:

Per capita income (p) = total income /population

So, we have:

\(p = \frac{\$4.8\ billion}{159.2\ thousand}\)

Evaluate the quotient

\(p = \$30150.75\)

The probability is approximately 0.9167 or 91.67%.

To find the probability that the sum of two dice numbers does not exceed 10, we need to determine the favorable outcomes (sums less than or equal to 10) and the total possible outcomes when rolling two dice.

There are 36 possible outcomes when rolling two dice because each die has six faces (1, 2, 3, 4, 5, and 6), and the total number of outcomes is obtained by multiplying the number of outcomes for each die (6 * 6 = 36).

Now let's determine the favorable outcomes (sums less than or equal to 10):

When the sum is 2: There is only one combination (1 + 1).

When the sum is 3: There are two combinations (1 + 2 and 2 + 1).

When the sum is 4: There are three combinations (1 + 3, 2 + 2, and 3 + 1).

When the sum is 5: There are four combinations (1 + 4, 2 + 3, 3 + 2, and 4 + 1).

When the sum is 6: There are five combinations (1 + 5, 2 + 4, 3 + 3, 4 + 2, and 5 + 1).

When the sum is 7: There are six combinations (1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, and 6 + 1).

When the sum is 8: There are five combinations (2 + 6, 3 + 5, 4 + 4, 5 + 3, and 6 + 2).

When the sum is 9: There are four combinations (3 + 6, 4 + 5, 5 + 4, and 6 + 3).

When the sum is 10: There are three combinations (4 + 6, 5 + 5, and 6 + 4).

Adding up the favorable outcomes, we get: 1 + 2 + 3 + 4 + 5 + 6 + 5 + 4 + 3 = 33.

Therefore, the probability that the sum of the two dice numbers does not exceed 10 is given by:

Probability = Favorable outcomes / Total outcomes = 33 / 36 = 11/12 ≈ 0.9167.

So, the probability is approximately 0.9167 or 91.67%.

The general solution to the differential equation. If initial conditions are given, we can solve for the constants C1 and C2.

The given differential equation is:

y ln x * (dx/dy) = [(y+1)/x]^2

We can solve this equation by separation of variables, which means we can rearrange the equation so that all the x terms are on one side and all the y terms are on the other side. Then, we can integrate both sides with respect to their respective variables.

First, we rewrite the equation in a form suitable for separation of variables:

y ln x dx = [(y+1)/x]^2 dy

Next, we separate the variables and integrate both sides:

∫y ln x dx = ∫[(y+1)/x]^2 dy

Integrating the left-hand side by parts, we have:

u = ln x dv = y dx

du/dx = 1/x v = (1/2) y^2

∫y ln x dx = (1/2) y^2 ln x - ∫(1/2) y dx

= (1/2) y^2 ln x - (1/4) y^2 + C1

where C1 is the constant of integration.

Integrating the right-hand side, we use the substitution u = y+1:

u = y+1 du = dy

∫[(y+1)/x]^2 dy = ∫(u/x)^2 du

= (1/x^2) ∫u^2 du

= (1/3x^2) u^3 + C2

where C2 is the constant of integration.

Substituting this back into the original equation, we have:

(1/2) y^2 ln x - (1/4) y^2 + C1 = (1/3x^2) (y+1)^3 + C2

This is the general solution to the differential equation. If initial conditions are given, we can solve for the constants C1 and C2.

According to the given statement The solutions to the equation x² + 12x + 11 = 0 in factored form are x = -1 and x = -11.

To solve the equation x² + 12x + 11 = 0 using factored form and the zero product property:
The quadratic formula is given by: x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c are the coefficients of the equation in the form ax² + bx + c = 0.

In this case, a = 1, b = 12, and c = 11. Plugging these values into the quadratic formula, we get:

x = (-(12) ± √((12)² - 4(1)(11))) / (2(1))

Simplifying further, we have:

x = (-12 ± √(144 - 44)) / 2

x = (-12 ± √100) / 2

Taking the square root of 100, we get √100 = 10.

So, the equation becomes:

x = (-12 ± 10) / 2

We can split this equation into two separate equations by using the plus and minus signs:

For the plus sign:

x = (-12 + 10) / 2

x = -2 / 2

x = -1

For the minus sign:

x = (-12 - 10) / 2

x = -22 / 2

x = -11

The solutions to the equation x² + 12x + 11 = 0 in factored form are x = -1 and x = -11.

By using the quadratic formula, we found that the equation can be factored as (x + 1)(x + 11) = 0, and the solutions are x = -1 and x = -11.

Answer:

The graph increases as it approaches -∞.

The graph decreases as it approaches ∞.

Step-by-step explanation:

f(x) = -x - 2x³ + 3x + 9

f(x) = -2x³ + 3x - x+ 9

f(x) = -2x³ + 2x+ 9

Look at the highest exponent(which is 3).

SInce the highest exponent is odd, that means that the graph approaches infinity in a different direction as per negative infinity. Since the highest exponent has a negative sign:

The graph is going UP as x-values get SMALLER ( To  -∞)

The graph is going DOWN as x-values get LARGER ( To  ∞)

To write an expression equal to logx(6), we need to understand what logarithm means. A logarithm is the inverse operation of exponentiation. It means that if we have an expression like x = a^b, we can find the value of b by taking the logarithm of x to the base a.

The expression loga(x) = b represents the value of the exponent that gives us x when a is raised to that power.

Now, to find an expression equal to logx(6), we need to determine the base of the logarithm. If the base is not specified, we assume it to be 10. Therefore, the expression logx(6) is equivalent to log10(6) / log10(x) (using the change of base formula). This expression represents the logarithm of 6 to the base x. In other words, it is the exponent to which x must be raised to get 6.

Alternatively, we can use natural logarithms (logarithms to the base e) to write the expression. In this case, logx(6) is equivalent to ln(6) / ln(x). The expression ln(6) represents the natural logarithm of 6, which is approximately equal to 1.792. This expression gives us the exponent to which e (the mathematical constant) must be raised to get 6.

In summary, the expression equal to logx(6) can be written as log10(6) / log10(x) or ln(6) / ln(x).
