Candle food is on sale for 20% of the original price what is the discount of the key if the original price is $1.35
Evgesh-ka [11]

Hi there!

To calculate a discount or a mark-up in the price of a retail item, you need to multiply the given price of the item by the percentage, like so:

1.35 × 0.2 = 0.27

Then you add or subtract as necessary. In your case you would subtract since you are trying to find a discount price.

1.35 - 0.27 = 1.08

So the final price of the product after the discount is $1.08

F(x) = x^2 - 3x+ 5 g(x) = 2x^2 - 4x - 11 what is h(x) = f(x) + g(x)
iogann1982 [59]

Hey there! :)

Answer:

h(x) = 3x² - 7x - 6

Step-by-step explanation:

Calculate h(x) by adding the two polynomials:

h(x) = f(x) + g(x):

h(x) = x² - 3x + 5 + 2x² - 4x - 11

Combine like terms:

h(x) = 3x² - 7x - 6

A drunkard executes a “random walk” in the following way: each minute he takes a step north or southm with probability 1/2 each,
valentina_108 [34]
Assume that a step to the north is in the positive direction and a step in the south is in the negative direction.

Then,

E(X_i)=50\left(\frac{1}{2}\right)-50\left(\frac{1}{2}\right)\\ \\=25-25=0

and

\sigma^2(X_i)=E(X_i^2)-E(X_i)^2 \\ \\ =50^2\left(\frac{1}{2}\right)+50^2\left(\frac{1}{2}\right)-0^2=2500\left(\frac{1}{2}\right)+2500\left(\frac{1}{2}\right)-0 \\ \\ =2500 \\ \\ \Rightarrow\sigma(X_i)=50

After 1 hour of independent steps,

E(X)=\sum_{i=1}^{60}E(X_i)=60(0)=0

and

\sigma^2(X)=\sum_{i=1}^{60}\sigma^2(X_i) \\  \\ =60(50)=300 \\  \\ \Rightarrow\sigma(X)=\sqrt{300}=17.32

Therefore, by Central Limit Theorem, the distribution of the random walk is normal with a mean of 0 cm and a standard deviation of 17.32 cm. He is expected to be somewhere around his starting point after 1 hour.

natulia [17]

Answer:

£6000

Step-by-step explanation:

Given:

Phillip Cage played, £21,000 was split at a ratio of 2:5 between the arena and Phillip Cage.

Question asked:

How much money did the arena make from Phillip Cage's concert?

Solution:

Ratio Arena and Philip cage in which money distributed = 2 : 5

Let ratio be x

Money earned by Arena = 2x

Money earned by Phillip Cage = 5x

Phillip Cage played total for =  £21,000

<u>Money earned by Arena + Money earned by Phillip Cage = £21,000</u>

2x+5x=21000\\7x=21000\\

Dividing both sides by 7

x=3000

Money earned by Arena = 2x = 2\times3000=6000

Thus, Arena made  £6000 from Phillip Cage's concert.
