PLSSS HELP!!! I really need help with this i have tried everything! Please provide instructions so I could learn how to do it! You are interested in finding a 98% confidence interval for the average number of days of class that college students miss each year. The data below show the number of missed days for 11 randomly selected college students. Round answers to 3 decimal places where possible. 9, 1, 2, 2, 9, 10, 1, 3, 7, 4, 2 a. To compute the confidence interval use a ? distribution. b. With 98% confidence the population mean number of days of class that college students miss is between ? and ? days. c. If many groups of 11 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population mean number of missed class days and about ? percent will not contain the true population mean number of missed class days.

Answer:

On dividing 3.185 ×  by 9.1 ×  the final answer in scientific notation is 3.5 × .

The quantity 3.185 times ten raised to the seventeenth power can written as 3.185 ×  .

The quantity 9.1 times ten raised to the eighth power can written as 9.1 ×  .

On dividing 3.185 ×  by 9.1 ×  ,

( 3.185 ×  )/( 9.1 ×  ) = 0.35 ×  = 0.35 × = 3.5 × (in scientific notation)

Scientific notation is a floating-point system in which the numbers are expressed as the products consisting of a number between one to ten multiplied by an appropriate power of ten.

On dividing 3.185 ×  by 9.1 ×  the final answer in scientific notation is 3.5 × .

4. 10

Step-by-step explanation:

You count the units of the length and width of the triangle which is also the same for the rectangle and l*w=the area (length is the longer side).

Halve the area of the rectangle to find the area of the triangle.

The area of this triangle is determined by forming a rectangle is 12.5 square units.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The area of this triangle is determined by forming a rectangle.

The dimensions of the rectangle are 5 and 2.5.

Area of triangle = Area of rectangle

Area of rectangle = Length × Width

Area of rectangle = 5 × 2.5

Area of rectangle = 12.5

Then the area of the triangle is 12.5 square units.

Answer:

Third

Step-by-step explanation:

h c

0 485

3 560

8 685

12 785

The table that shows the relationship between h, the number of hours John’s brother works, and c, the total cost of the project is third table.

Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.

Example - 2 × 3 means 2 is added three times or 3 is added 2 times.

Given that John paid $485 to build a deck.

And he will pay $25 per hour to his brother for building the deck.

one hour of work costs John $25 + $485 .

Total cost of building deck = $25 × h number of hours + $485

3 hour of work costs $25 × 3 = $75 + $485 = $560

8 hour of work costs = $25 × 8 = $200 + $485 = $685

12 hour of work costs = $25 × 12 = $300 + $485 = $785

Therefore, the third table suggests the total cost of work.

Step-by-step explanation:

(2/3)(-4)(9) = -24

(-3/4)(7/8)=-21/32

(2 3/5) (7/9)=91/45

Answer:

c. (y + z = 6) ⋅ −3

Step-by-step explanation:

We want to use elimination to eliminate y in a system of equations

y + z = 6

3y + 4z = 1

We can take the first equation and multiply by -3 to make the y term -3 so when we add  the equations -3y + 3y =0

-3(y + z = 6)

3y + 4z = 1

--------------------

-3y  -3z = -18

3y + 4z = 1

---------------------

0y  +z   = -17

Answer:

c. (y + z = 6) ⋅ -3

Explanation:

Equation P : y + z = 6

Equation Q : 3y + 4z = 1

In order to solve by elimination and remove the y-term, the coefficients of y must be same or negative to each other in both the equations.

So to make the y co-efficient similar here, multiply the first equation by -3

When done: (y + z = 6) · -3 = -3y - z = -18

Solving steps:

-3y - 3z = -18

3y + 4z = 1

------------------

    z = -17

There the y-term has been removed.

Answer:

3.62 inches

Step-by-step explanation:

Given :

Ed's string length = 21.72 inches

Georgiana's string length = 1/6 of Ed's string length

To Find :

Georgiana's string length

Solving :

Georgiana's string length = 1/6 of Ed's string length

Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Georgiana's string length = 3.62 inches

Answer:

3.62 inches

Step-by-step explanation:

Step-by-step explanation:

Given that Ed's string length is = 21.72 inches

And that Georgiana's string length is = 1/6 of Ed's string length

We need to find Georgiana's string length

Georgiana's string length = 1/6 of Ed's string length

And Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Which would bring  us that Georgiana's string length is = 3.62 inches

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30
