Okay, here are the steps to find the p-value:

1) The nationwide proportion of Americans who invest in the stock market is 55% (0.55)

2) The test statistic for Georgia is 1.75

3) To calculate the p-value, we need to know the degrees of freedom (df) and the critical value of the test statistic.

4) The df = 1, since we're comparing a single proportion (Georgia) to a fixed value (national average).

5) The critical value at df = 1 and 95% confidence is 3.84 (for a two-tailed test)

6) Since the test statistic of 1.75 is less than 3.84, we look up 1.75 in tables to find the p-value.

7) For a test statistic of 1.75 and df = 1, the p-value is 0.1860.

So the p-value to test if the proportion of Georgians who invest in the stock market is different than the nationwide average is 0.1860.

Step-by-step explanation:

The required predicted sales n the 15th day is given as 244 ice creams.

Given that,
an ice cream truck operator tracks total daily sales rounded to the nearest dollar for 14 days as shown in the following 1: 201 2:249 3: 285 4:297 5:288 6:262 7:256 8:240 9:210 10:199 11:192 12:215 13:237 14:290.

The average of the values is the ratio of the total sum of values to the number of values.

Here,
calculate average sales,
= [201 +249 + 285 + 297 + 288 + 262 + 256 + 240 + 210 + 199 + 192 + 215 + 237 + 290] / 14
= 244
So on the 15 day the sale can be predicted as 244.

Thus, the required predicted sales n the 15th day is given as 244 ice creams.

The equation for the regression line from the data is y = -0.98x + 56.8

Given data ,

To find the equation of the regression line, we will use the method of least squares. The regression line is represented by the equation:

y = mx + b

where m is the slope of the line and b is the y-intercept.

We need to calculate the values of m and b. Let's begin by finding the mean values of x and y:

Mean of x (x₁) = (6 + 13 + 14 + 10 + 13) / 5 = 12.2

Mean of y (y₁) = (25 + 44 + 46 + 52 + 57) / 5 = 44.8

Next, we calculate the deviations from the mean for both x and y:

Deviation from the mean of x (Δx) = x - x₁

Deviation from the mean of y (Δy) = y - y₁

Now, we calculate the sum of the products of the deviations from the mean:

Σ(Δx * Δy) = (6 - 12.2) * (25 - 44.8) + (13 - 12.2) * (44 - 44.8) + (14 - 12.2) * (46 - 44.8) + (10 - 12.2) * (52 - 44.8) + (13 - 12.2) * (57 - 44.8)

Σ(Δx * Δy) ≈ -51.6

Next, we calculate the sum of the squared deviations from the mean of x:

Σ(Δx²) = (6 - 12.2)² + (13 - 12.2)² + (14 - 12.2)² + (10 - 12.2)² + (13 - 12.2)²

Σ(Δx²) ≈ 52.8

Now, we can calculate the slope (m) using the formula:

m = Σ(Δx * Δy) / Σ(Δx²)

m ≈ -51.6 / 52.8 ≈ -0.98

Finally, we can calculate the y-intercept (b) using the formula:

b = y₁ - m * x₁

b ≈ 44.8 - (-0.98) * 12.2 ≈ 56.8

Hence , the equation of the regression line for the given data is:

y = -0.98x + 56.8

Answer:

Step-by-step explanation:

if 2/3 was 3/3 then it would be divided into 3 there for 3

The equation in terms of t that models the situation is given by

\(8192(1+\frac{0.01}{12} )^{12t} = 25710\).

We know that the interest on a loan or deposit that is accrued on both the initial principal and the total interest from prior periods is known as compound interest and it can be calculated as

\(A = P(1+\frac{r}{n})^{nt}\),

where P is the initial principal, r is the rate of interest, n is the number of times interest was charged for each time period, t is the amount of time that has passed and A is the final amount.

Here, P = 8192, r = 10% = 10/100 = 0.01, n = 12 and A = 25,710

So, we can write

\(8192(1+\frac{0.01}{12} )^{12t} = 25710\)

Therefore the required equation is

\(8192(1+\frac{0.01}{12} )^{12t} = 25710\)

Answer:

C. The trails are not independent.

The probability of drawing one marble will not be independent of others thus option (c) is correct.

The probability of an event occurring is defined by probability.

Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

As per the given,

Drawing 5 marbles from a bag with 10 red, 8 green, and 12 yellow marbles without replacement.

In without replacement, the remaining balls in each draw will go to be decreased thus they will be dependent events so binomial distribution will not be applied.

Hence "One marble's likelihood of being drawn won't be independent of the other marbles".

The equation you used is correct, but the differential equation does not include the growth rate. The growth rate is proportional to the current population, so the differential equation should look like this:  dp/dt = kP - 20,000t

dp/dt = kP - 20,000t  , Where k is the growth rate. To solve this equation, we can use the separation of variables: dp/P = kdt - 20,000tdt

Integrating both sides, we get:

ln|P| = kt - 20,000t^2/2 + C, Where C is the integration constant. To find C, we can use the initial population of 200,000:

ln|200,000| = -0.099t - 20,000t^2/2 + C

=>C = ln|200,000| + 0.099t + 20,000t^2/2  .Therefore, the population of mosquitoes at any given time t is:

P = 200,000e^(-0.099t - 20,000t^2/2 + ln|200,000| + 0.099t + 20,000t^2/2)  = 200,000e^(ln|200,000|)  = 200,000

Answer:

\(\displaystyle\)\(\displaystyle f'(1)=-\frac{9}{e^3}\)

Step-by-step explanation:

Use Quotient Rule to find f'(x)

\(\displaystyle f(x)=\frac{3x^2+2}{e^{3x}}\\\\f'(x)=\frac{e^{3x}(6x)-(3x^2+2)(3e^{3x})}{(e^{3x})^2}\\\\f'(x)=\frac{6xe^{3x}-(9x^2+6)(e^{3x})}{e^{6x}}\\\\f'(x)=\frac{6x-(9x^2+6)}{e^{3x}}\\\\f'(x)=\frac{-9x^2+6x-6}{e^{3x}}\)

Find f'(1) using f'(x)

\(\displaystyle f'(1)=\frac{-9(1)^2+6(1)-6}{e^{3(1)}}\\\\f'(1)=\frac{-9+6-6}{e^3}\\\\f'(1)=\frac{-9}{e^3}\)

Answer:

\(f'(1)=-\dfrac{9}{e^{3}}\)

Step-by-step explanation:

Given rational function:

\(f(x)=\dfrac{3x^2+2}{e^{3x}}\)

To find the value of f'(1), we first need to differentiate the rational function to find f'(x). To do this, we can use the quotient rule.

\(\boxed{\begin{minipage}{5.5 cm}\underline{Quotient Rule for Differentiation}\\\\If $f(x)=\dfrac{g(x)}{h(x)}$ then:\\\\\\$f'(x)=\dfrac{h(x) g'(x)-g(x)h'(x)}{(h(x))^2}$\\\end{minipage}}\)

\(\textsf{Let}\;g(x)=3x^2+2 \implies g'(x)=6x\)

\(\textsf{Let}\;h(x)=e^{3x} \implies h'(x)=3e^{3x}\)

Therefore:

\(f'(x)=\dfrac{e^{3x} \cdot 6x -(3x^2+2) \cdot 3e^{3x}}{\left(e^{3x}\right)^2}\)

\(f'(x)=\dfrac{6x -(3x^2+2) \cdot 3}{e^{3x}}\)

\(f'(x)=\dfrac{6x -9x^2-6}{e^{3x}}\)

To find f'(1), substitute x = 1 into f'(x):

\(f'(1)=\dfrac{6(1) -9(1)^2-6}{e^{3(1)}}\)

\(f'(1)=\dfrac{6 -9-6}{e^{3}}\)

\(f'(1)=-\dfrac{9}{e^{3}}\)

Step-by-step explanation:

The sum of the interior angles of a triangle is 180:

\(\angle{EAB}+\angle{ABE}+\angle{AEB} = 180\)

\(\Rightarrow 2x + (180 - 4x) + (180 - 6x) = 180\)

\(\Rightarrow 180 - 8x = 0\)

Solving for x,

\(x = 22.5\)

The sum of the interior angles of a quadrilateral is 360:

\(\angle{DAB}+\angle{ADC}+\angle{DCB}+\angle{ABC}= 360\)

\(\Rightarrow 2x+79+32+(360 - 5x) = 360\)

\(\Rightarrow -3x + 111 = 0\)

The break-even point is the point at which income equals expenses.

Let that number of books sold be x

Printing costs = 13200 + 25x

Book sale = 40x

At break-even, the printing costs is the same as book sale.

13200 + 25x = 40x

15x = 13200

x = 13200/15 = 880

Let that be x

\(\\ \rm\Rrightarrow 13200+25x=40x\)

\(\\ \rm\Rrightarrow 40x-25x=13200\)

\(\\ \rm\Rrightarrow 15x=13200\)

t >± 1.895

t= 0.1705

Step-by-step explanation:

The null and alternative hypotheses are

H0: μd=0 Ha: μd>0

Significance level is set at ∝= 0.05

The critical region for  t  df=7       t >± 1.895

The test statistic under H0 is

t = d/ sd/ √n

Which has t distribution with n-1 degrees of freedom

Employee        After  Before         d = after - before        d²

1                          6         5               1                                  1

6                         3          6              -3                               9

7                         5          3              2                               4

8                          6        7               -1                                1      

∑                                                    14                              84    

d`= ∑d/n= 14/8= 1.75

sd²= 1/8( 84- 14²/8) = 1/8 ( 84 - 24.5) = 59.5

sd= 7.7136

t= 3/ 7.7136/ √8

t= 0.1705

Since the calculated value of t= 0.1705 < ± 1.895  therefore reject the null hypothesis at 5 % significance level . On the basis of this we cannot conclude that the number of absences has declined.
