The critical probability of a critical value of α = 0.47 is [tex]Z_{0.47}[/tex] = 0.77.

A crucial value is the test statistic's value that establishes a confidence interval's upper and lower boundaries, or the level of statistical significance for a given test.

Given:

The critical value, α = 0.47

Calculate the critical probability by the formula given below,

[tex]Z_\alpha = 1 - ( \alpha / 2)[/tex]

[tex]Z_{0.47}[/tex] = 1 - (0.47 / 2)

[tex]Z_{0.47}[/tex] = 1 - 0.235

[tex]Z_{0.47}[/tex] = 0.765 = 0.77

Therefore, the critical probability of a critical value of α = 0.47 is [tex]Z_{0.47}[/tex] = 0.77.

Hello,

a. The variable t represents the number of years since 1999, so the constraints for t can be written as t ∈ {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}.

b. To find the value of S(7), we substitute t = 7 into the function: S(7) = 1.084(7) + 17.392 = 22.688.

c. In context, the value of S(7) represents the amount of money, in billions of dollars, that the US government spent on science, space, and technology 7 years after 1999.

d. The key feature that is found when solving S(t) = 0 is the y-intercept of the graph of S(t). The y-intercept is the point where the graph crosses the y-axis.

e. The value for S(t) = 0 is not reasonable for the context because it represents the amount of money spent on science, space, and technology in 1999, which would be a negative number of years after 1999.

(a) The population of the state was 18.5 million in 2000. (b) The population of the state reaches 26.6 million by 2002

A population is a distinct collection of people, whether that group consists of a nation or a population that shares a particular trait. A population is the people from which a statistical sample is taken in statistics. As a result, a population can be defined as any group of people with something in common.

(a) The right response is 18.5

Given that

t = 0,

A = 18.5

(b) 2002.

Using the formula

18.5e 0.173 x t

Given,

A= 26.6

Then,

A = 18.5 x

[tex]e^{(0.1708t)} 26.6 = 18.5 x[/tex]

[tex]\frac{26.6}{18.5}= e^{(0.1708t)}[/tex]

The customer who purchases 10 Microsoft 365 Business Premium licenses at $22 each per month, for a full year, then 6 months later decides they only need 5 licenses for the remainder of the year, would pay a total charge of $1,980 with a credit of $660 for the year.

The total charge the customer will pay is based on the difference between the total charge for the year and the prorated charge of credit for non-usage.

The charge per month for Microsoft 365 =  $22

The charge per month for 10 Microsoft 365 = $220 ($22 x 10)

The charge for 1 year for one Microsoft 365 = $264 (22 x 12)

The charge for 6 months for 10 Microsoft 365 = $1,320 ($220 x 6)

The charge for 12 months for 10 Microsoft 365 = $2,640 (220 x 12)

The prorated charge for 6 months for 5 Microsoft 365 returned = $660 ($2,640 x 5/10 x 6/12)

The initial total charge for the year = $2,640

The total credit for the year = $660

The total charge for the year = $1,980 ($2,640 - $660)

Thus, the customer will pay $1,980 after receiving a prorated credit for 5 returned licenses worth $660.

Answer:

function 2

Step-by-step explanation:

function 1 has a slope of 8/7 which is equal to 0.75 and function 2 has a slope of 1 so function 2 is greater than function 1.

Answer: <

Step-by-step explanation:

One number is less than another number if their difference is less than zero.

Since x=2y-4 - 0.75 = -0.75 which is less than zero, x=2y-4 is less than 0.75

Therefore, x=2y-4 is 0.75 less/lower than 0.75

What is Linear Equation in One Variable?

A linear equation is a one-variable equation of a straight line. The variable's only power is 1. Linear equations in one variable have the form ax + b = 0 and are solved using simple algebraic techniques.

Solution:

Let, Songs Downloaded be x

Total Charges of Company A = 15 + 0.75*x

Total Charges of Company B = 0.9*x

(i) Total Charges by Company A = Total Charges by Company B

15 + 0.75*x = 0.9*x

is that even a question bro?

Answer:

1/4 and -20

Step-by-step explanation:

"Slope" just means the change in y divided by the change in x. In the first graph, the slope is the change in depth divided by the change in hours.

Using the equation, slope = (y - y1)/(x - x1), you can plug in 2 points and solve. I see that the line goes through the points (4,1) and (8,2), so I'll use these. Make sure that (x,y) are from the same point and (x1,y1) are from the same point.

slope = (2 - 1)/(8 - 4)

slope = 1/4

You can do the same process for the second graph but you'll use different points. I see the points (2,80) and (4,40), so I'll use those.

slope = (40 - 80)/(4 - 2)

slope = -40/2

slope = -20

The expected value is 160 and SE for the number of students in the sample is 9.78

a)Given: students of which 25000 of which 10000 are older than 25 and 25000-10000=15000 are not older than 25.

we represent 400 students by drawing 400 tickets from a box that contains 15000 tickets labeled 0 and 10000 tickets labeled 1

Expected value and standard deviation of a box:

First, we determine the expected value of the box, which is the sum of all values on the tickets by the number of tickets.

[tex]expected value box=\frac{15000*0+10000*1}{25000}\\\\ =\frac{10000}{25000} =\frac{2}{5}[/tex]

expected value box=0.4

let us next determine the standard deviation using the shortcut formula:

SD=(big number-small number)*√fraction with small number*fraction with a small number.

[tex]SD=(1-0)*\sqrt{\frac{10000}{25000} *\frac{15000}{25000} \\\\SD=1*\sqrt{\frac{2}{5} *\frac{3}{5} } \\SD=1*\sqrt{\frac{6}{25} } =\frac{\sqrt{6} }{5}[/tex]

SD=0.4899.

Expected value sum=Number of draws*expected value box

                                  =400*0.4

Expected value sum=160

standard error of the sum is the product of the square root of the number of draws and the standard deviation of the box.

SE Sum=√number of draws*SD box

SE Sum=√400*0.4899

             =20*0.4899

 SE Sum=9.78

b)EXpected value and standard error:

The expected value of the percentage is the expected value of the sum divided by the number of draws.

Expected value percentage=Expected value sum/Number of draws*100%

                                               160/400*100

                                              =0.4*100%

Expected value percentage=400%

The standard error of the percentage is the standard error for the sum divided by the sample size:

SE%=SE for number/Number of draws*100%

         =9.798/400*100%

          =0.0245*100%

  SE% =2.45%

Main Body:

We use the Inventory identity to solve for ending inventory

Beginning Inventory + Purchase = ending Inventory + used

20,800 +159,000 = ending inventory + used materials

used materials:

135,600 direct

12,400 indirect

148,000 total materials used

20,800 + 159,000 = Ending Inventory + 148,000

20,800 + 159,000 - 148,000 = Ending Inventory

Ending Inventory = 31,800

Ages of Tristan, Richard, and Pablo are in the order 6:7:4.

Detailed explanation:

Pablo is six years younger than Richard, seven years older than Tristan, and five years younger than Richard.

We can multiply the ratios of Pablo's age to Richard's age and Pablo's age to Tristan's age to determine the ratio of Tristan's age to Richard's age before determining the ratio of Tristan's age to Pablo's age.

These ratios add up to 6/7 * 5/4 = 30/28.

Pablo's age to Richard's age is 6:7, thus we may multiply this ratio by the age of Richard by Tristan's age to determine the age of Pablo, Richard, and Tristan.

Thus, the ratio of Pablo's age to Richard's age to Tristan's age is 6:7:4.
