Answer: Your question options are not legible but the inverse of the function is f-1(x) = (x + 2) / 2

Step-by-step explanation:

y = 2x + 2

Make x the subject of formula:

2x = y - 2

x = (y - 2) / 2

Now substitute y for x:

(x - 2) / 2

Y = (x - 2) / 2 is the inverse equation of the above graph.

A normal distribution has mean μ and standard deviation σ .An x-value is randomly selected from the distribution. Find P(μ−σ≤x≤μ

dlinn [17]

Answer:

The probability that a randomly selected x-value lies between μ − 2σ and μ is the shaded area under the normal curve shown. P(μ − 2σ ≤ x ≤ μ) = 0.135 + 0.34 = 0.475

The point-slope form of the equation of the line that passes through (-9,-2) and (1,3) is y-3=1/2(x-1) what is the slope-interce

Vikentia [17]

Answer:

y = (1/2)x + 2 1/2

Step-by-step explanation:

y - 3 = (1/2)(x - 1)

Distribute the 1/2

y - 3 = (1/2)x - 1/2

Add 3 to both sides

y = (1/2)x + 2 1/2

A shopkeep offers a discount of 20% on all the articles at his shop and still makes a profit of 12%. What is the CP of an articl

Arte-miy333 [17]

Given info:-

A shop keeper offers a discount of 20% on all the articles at his shop and all makes a profit of 12%.

What is the CP of an article whose MP is Rs. 280 ?

Explanation:-

Given that

The Marked Price of an article (M) = Rs. 280

Discount on it = 20%

Discount (D) = MD/100

⇛ Discount = (280×20)/100

⇛ Discount = 28×2

⇛ Discount =56

Selling Price = Marked Price - Discount

⇛ Selling Price = 280-56

⇛ Selling Price = Rs. 224

Selling Price of the article = 224

Profit on it = 12%

We know that

Cost Price = (100×SP)/(100+g)

⇛ CP = (100×224)/(100+12)

⇛ CP = 22400/112

⇛ CP = 200

Therefore, The CP = Rs. 200

The Cost Price of the article = Rs. 200.

Formula:-

Discount (D) = MD/100

M = Marked Price

Selling Price = Marked Price - Discount
Cost Price = (100×SP)/(100+g)

SP = Selling Price

g = gain or profit
