Answer:

Green is 0.3, Yellow is 0.1

There are 12 green pins in the bag

Step-by-step explanation:

The probability is the ratio between the possible outcomes over the total outcomes

∵ A bag contains some green, yellow, purple and grey pins

∵ The probability of picking a purple pin P(purple) = 0.35

∵ The probability of picking a grey pin P(grey) = 0.25

→ The total of all possible outcomes is 1

∴ The sum of the probability of green and yellow pins = 1 - 0.35 - 0.25

∴ The sum of the probability of green and yellow pins = 0.4

∴ P(green) + P(yellow) = 0.4 ⇒ (1)

∵ The probability of picking a green pin is 3 times the probability

   of picking a yellow pin

∴ P(green) = 3 P(yellow) ⇒ (2)

→ Substitute (2) in (1)

∴ 3 P(yellow) + P(yellow) = 0.4

∴ 4 P(yellow) = 0.4

→ Divide both sides by 4

∴ P(yellow) = 0.1

∴ The probability of picking a yellow pin is 0.1

→ Substitute P(yellow) in (20 by 0.1

∴ P(green) = 3(0.1)

∴ P(green) = 0.3

∴ The probability of picking a green pin is 0.3

∴ Green = 0.3, Yellow = 0.1

∵ There are 14 purple pins in the bag

∵ P(purple) = 0.35

∴ 0.35 of purple pins = 14

→ To find the total number of pins in the bag divide 14 by 0.35

∴ The total number of pins = 14 ÷ 0.35

∴ The total number of pins = 40 pins

∵ P(green) = 0.3

∴ The number of green pins = 0.3 × 40

∴ The number of green pins = 12 pins

∴ There are 12 green pins in the bag

Find the area of triangle then the square also I was ACTUALLY THE IMPOSTER AHAHAHAHAHAHHAHA

Answer:The answer would be infinite solutions

Step-by-step explanation:

Answer:

Step-by-step explanation:

In order to know that this is true, you must do simple steps to solve it. The first equation (y = 2 (x + 4)) is unsolved. In order to make it equal to the second equation (Y = 2 x + 8

), you must first use the distributive property, so multiply the x and the 4 in the first equation to get Y= (2x + 8), remove the parenthesis, and now, the equations are equal. Since they are equal, they overlap each other on the graph, so any number replacing x will change both equations equally, so they will forever overlap no matter what.

Hope this helps! [?][?]

Answer:

Part A:  [tex]\frac{1}{2}[/tex]

Part B: [tex]\frac{10}{9}[/tex]

Step-by-step explanation:

Part A: What is the reciprocal of 2.

2 is just [tex]\frac{2}{1}[/tex] in fraction terms. To find the reciprocal, you just have to flip it over. That would get to [tex]\frac{1}{2}[/tex]. Therefore, the reciprocal is [tex]\frac{1}{2}[/tex].

Part B: What is the reciprocal of 9 over 10?

9 over 10 in numerical terms is just [tex]\frac{9}{10}[/tex]. o find the reciprocal, you just have to flip it over. That would get to [tex]\frac{10}{9}[/tex]. Therefore, the reciprocal is [tex]\frac{10}{9}[/tex].

Hope this helped! If not, please let me know! <3

2y+3=15

2y=12

y=6

the answer is A and D

when you differentiate the question you find that the maximum point is (0,0)i.e

[tex] \frac{dy}{dx} = - 8x[/tex]

when dy/dx is 0 values of x are 0,0

and the function shows that valies of x are real numbers.

The domain of the graph is (−∞,∞), {x|x∈R} and the maximum point (0,0) which is the correct answer would be options (A) and (D)

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

Given function as

f(x) = -4x²

The range is the set of values that correspond with the domain.

Range: (−∞,0], {y|y≤0}

Domain: (−∞,∞), {x|x∈R}

and the function shows that values of x are real numbers.

The maximum point is when differentiating the function, which is (0,0) i.e

dy/dx = -8x

Values of x are 0 when dy/dx is 0.

Hence, the domain of the graph is (−∞,∞), {x|x∈R} and the maximum point (0,0) which is the correct answer would be options (A) and (D)

Answer:

Blouse = $13.00

Jeans = $25.50

Step-by-step explanation:

x = blouse

y = jeans

x + y = 38.5

y = x + 12.5

Use substitution:

x + x + 12.5 = 38.5

2x = 26

x = 13

Blouse = $13.00

Jeans = $25.50

The price of  Blouse is $13.00 and price of Jeans is $25.50.

Two or more expressions with an Equal sign is called as Equation.

Let x represents the price of blouse and y represents the price of jeans.

mary bought a blouse and a pair of jeans for 38.50

x+y=38.5

jeans cost 12.50 more then the blouse

y=12.5+x

We need to find the price of jeans.

Substitute y value in above equation.

x + x + 12.5 = 38.5

Add the like terms

2x+12.5 = 38.5

Subtract 12.5 on both sides

2x = 26

Divide both sides by 2

x = 13

Hence, the price of  Blouse is $13.00 and price of Jeans is $25.50.
