Answer:

Y1 is parallel to Y2 and L1 to L2.

Step-by-step explanation:

A line is 180°. To find the degree the angles I subtracted 117 and 63 by 180 to find thair respective angles. (Also 117+63 equil 180) meaning that the Y's and L's are parallel to each other.

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].

Answer:

10/29

Step-by-step explanation:

[tex]2\frac{9}{10}=\frac{29}{10}[/tex]

Reciprocal of [tex]\frac{29}{10}= \frac{10}{29}[/tex]

Since we know that the 2 lines are parellel, we know that the angles will add up to 180

sooo

180-119=61 (The angle in the traingle)

We know that the angles of a trinalge add up to 180

61+18+e=180

e=101 degrees

Answer: 1 over 2

Step-by-step explanation: if you take the coordinates of the pre-image, letter A. which is (2,6) and the coordinates of the transformed image A’ which is (1,3) and only use the first number of the coordinates. You would put the number of of the pre-image as the denominator and the number of the transformed image as the numerator. And It would become 1/2.

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: (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}.

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.
