Is the equation y=-2x+7 parallel

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].

The factored expression of -3x^2 +17x -20 is (-3x + 5)(x-4)

The expression is given as:

-3x^2 +17x -20

Expand the expression

-3x^2 +12x + 5x -20

Factorize the expression

-3x(x - 4) + 5(x - 4)

Factor out x - 4

(-3x + 5)(x-4)

Hence, the factored expression of -3x^2 +17x -20 is (-3x + 5)(x-4)

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

Answer:

0.012yK

Step-by-step explanation:

[tex]\frac{y*12}{1000} K[/tex] > K=1,000

12 divided by 1000 is 0.012.

The required annual salary for Kareem is 0.012yK.

Given that,
Kareem earns y dollar per month at his accounting job. Express his annual salary using the K abbreviation found in classified ads is to be determined.

The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
$1 K = $1000  (for a year)

Since salary for a month is y
Salary for a year = 12 * y
Transforming it into K abbreviation
Multiplied and divide by 1000 on the right side
Annual salary = 12 y 1000 /1000
                       = 12/1000 * y K
                       = 0.012yK

Thus, the required annual salary for Kareem is 0.012yK.

Answer: (C)

6,2,2,2

Step-by-step explanation:

A mean is an arithmetic average of a set of observations. The set of population data that is the least dispersed from its mean is {6, 2, 2, 2}.

A mean is an arithmetic average of a set of observations. it is given by the formula,

[tex]\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}[/tex]

To solve the problem we will find the mean of each population set and then add the difference between the mean and each data point.

A.)

[tex]Mean = \dfrac{2+3+2+9}{4} = \dfrac{16}{4} =4[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|4-2|=2\\|4-3|=1\\|4-2|=2\\|4-9|=5[/tex]

Thus, the dispersion of the population from the means is 10 (2+1+2+5).

B.)

[tex]Mean = \dfrac{4+0+4+0}{4} = \dfrac{8}{4} =2[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|2-4|=2\\|2-0|=2\\|2-4|=2\\|2-0|=2[/tex]

Thus, the dispersion of the population from the means is 8 (2+2+2+2).

C.)

[tex]Mean = \dfrac{6+2+2+2}{4} = \dfrac{12}{4} =3[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|3-6|=3\\|3-2|=1\\|3-2|=1\\|3-2|=1[/tex]

Thus, the dispersion of the population from the means is 6 (3+1+1+1).

D.)

[tex]Mean = \dfrac{9+3+5+3}{4} = \dfrac{20}{4} =5[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|5-9|=4\\|5-3|=2\\|5-5|=0\\|5-3|=2[/tex]

Thus, the dispersion of the population from the means is 8 (4+2+0+2).

Hence, the set of population data that is the least dispersed from its mean is {6, 2, 2, 2}.
