We can do this using the binomial probability distribution:

5C2 * (1/2)^2 * (1/2)^3 = 10 * 1/32

= 5/16

The coin has to sides, so there are 2 possible choices given each of the 5 times. 2(5)=10. then, you divide 2 by that number (2/10), which is equal to 1/5

Type the correct answer in the box. Jason builds doghouses for a pet store. Each doghouse is a wooden structure with a rectangul

Basile [38]

Answer:

Width = 3 feet

Length = 7 feet

Step-by-step explanation:

x represents the width of doghouse so,

Width = x

Length is 4 times more than its width

Length = x+4

Area of doghouse = 21 square feet

We know

Area of rectangle = Length * Width

21 = (x+4)*x

21 = x^2+4x

=> x^2+4x-21=0

Solving the above quadratic equation by factorization to find the value of x

x^2+7x-3x-21=0

x(x+7)-3(x+7)=0

(x+7)(x-3)=0

x+7 =0 and x-3=0

x= -7 and x =3

Since the width of rectangle can never be negative so, x=3

Width =x = 3 feet

Length = x+4 = 3+4 = 7 feet

Prepare the Sales Budget assuming: 1. Expected sales volume: 8,000 units for the first quarter, an increase of 20% is expected f

solong [7]

Answer:

Sales budget $ for the 4 quarters is $ 600,000 $ 720,000 $594000 and $ 825,000

Production Budget in units for the four quarters i s 7997.6 9000 8900 and 10,350 units

Step-by-step explanation:

Sales Budget

Quarters I II III IV

Sales Volume 8000 9600 7200 10,000

Sales Price $75.00 $75.00 $ 82.50 $82.50

Sales $ 600,000 720,000 594000 825,000

We calculate the sales volume by applying the given percent to the sales units for each quarter. Then multiply it with the sales price to get the sales budget.

Production Budget

Quarters I II III IV

Sales Volume 8000 9600 7200 10,000

+ Desired

Ending Inv. 2400 1800 3500 3850

Less Opening ----- 2400 1800 3500

Production 7997.6 9000 8900 10,350

We find the production budget units by adding the desired ending inventory and subtracting the opening inventory from the sales units calculated above. The ending inventory of one quarter is the opening inventory of the next quarter.As we do not know the ending inventory of the previous year we cannot find the opening inventory of the 1st quarter of the year .

Which table shows exponential decay? A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The sec

zvonat [6]

Answer:

The first table; the first column is labeled x with entries 1, 2, 3, 4. The second column is labeled y with entries 16, 8, 4, 2.

Step-by-step explanation:

Exponential decay means that the graph or table is exponentially decreasing. Meaning, if you went from point 4 to 1, you would see an exponential increase. Other tables show other forms of functions, such as quadratic, or linear. To find out which rate it is decaying by, ask yourself, at 0, what is the y output? You can then divide the output of 0 by 1, and so on. If it is decaying at a consistent rate, then you know it is exponential. If you do not need to divide, but know it is decaying at a rate of two, it is linear. If it does not divide the first time smoothly, it is quadratic. It could also be a number of things.

I hope this helps you. We studied this quite a while ago, and I do not remember the equation at the tip of my tongue, and I do not want to give you wrong information. Have a great rest of your day!
