Answer: 5/9 (I am not sure if it is right don't take my word for it just incase if you want to do it at your own risk)

Step-by-step explanation:

There is a 8 main wyas 3 colors, 3 numbers, head or tails

if you are not spinning red it's 2 colors you can get

if you want to flip tails that is one

if you don't want to spin an even number there is 2 other numbers

2+2+1=5

5/9 is your chance or 0.5(5 is repeating)

Please check my answer : Find the equation of the line that has a slope of 8 and passes through the point (-3,4). I got y=8x-20

Paladinen [302]

The answer is y = -8x - 20. If you were to use y = 8x - 20 then you'd get 4 = -44, which, obviously, is not true. To fix it all you need to do is add a negative sign in front of the 8. y = -8x - 20.

Write a formula for quadratic function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).

d1i1m1o1n [39]

Answer:

y = - 8x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6), thus

y = a(x - 0)² + 6, that is

y = ax² + 6

To find a substitute (- 1, - 2) into the equation

- 2 = a(- 1)² + 6, that is

- 2 = a + 6 ( subtract 6 from both sides )

- 8 = a

y = - 8x² + 6

In the Holiday Shop the manager wants 20% of the total inventory in the stockroom and the rest displayed on the floor. After mee

Lilit [14]

Answer:

Total inventory: $175,000

Inventory in the stockroom: $35,000.

Inventory on the selling floor: $140,000.

Step-by-step explanation:

Let x be the the total inventory.

We have been given that in the Holiday Shop the manager wants 20% of the total inventory in the stockroom. You placed $35,000 of inventory in the stockroom.

We can set an equation such that 20% of x equals $35,000.

$\frac{20}{100}\cdot x=\$35,000$

$0.20x=\$35,000$

$\frac{0.20x}{0.20}=\frac{\$35,000}{0.20}$

$x=\$175,000$

Since $35,000 of inventory in the stockroom, so we will subtract $35,000 from $175,000.

$\text{Amount of the inventory on the selling floor}=\$140,000$

Therefore, $140,000 of the inventory on the selling floor.
