Modulus of a number always yields Positive Result.Modulus is defined is as follows

|x|=x, if x>0.

|-x|=-(-x)=x, if x<0

|x|=0, if, x=0.

→ |-5|=5

⇒The best way of representing , 5 on the number line is

Option C

A number line from negative 5 to positive 5 with increments of 1 is drawn. A horizontal line is drawn from 0 to positive 5, and 5 is written above it.

Y − 6 =3/5(x + 5); (0, 8)

Rom4ik [11]

The equation of a line parallel to the given line and passing through the point (0, 8) is 5y - 3x = 40

<h3>Equation of a line</h3>

The equation of a line in point-slope form is expressed as;

y - y0 = m(x -x0)

where

m is the slope

(x0, y0) is the point on the line

Given the following parameters

Point (0,8)

Slope from the equation = 3/5

Substitute

y - 8 = 3/5(x - 0)
5(y -8) =3x

5y - 40 = 3x

5y - 3x = 40

Hence the equation of a line parallel to the given line and passing through the point (0, 8) is 5y - 3x = 40

State if the triangles in each pair are similar. If so, State how you know they are similar and complete the similarity statemen

Sidana [21]

Answer: a) similar, SSS similarity

Step-by-step explanation:

ΔLSR sides in order from least to greatest are: 24, 33, 36

ΔLNM sides in order from least to greatest are: 112, 154, 168

If the triangles are similar then their corresponding sides will be proportional

$\dfrac{LS}{LN}=\dfrac{SR}{NM}=\dfrac{LR}{LM}\\\\\\\\\\\dfrac{LS}{LN}=\dfrac{24}{112}\quad \rightarrow \dfrac{3}{14}\\\\\\\dfrac{SR}{NM}=\dfrac{33}{154}\quad \rightarrow \dfrac{3}{14}\\\\\\\dfrac{LR}{LM}=\dfrac{36}{168}\quad \rightarrow \dfrac{3}{14}$

Their corresponding sides are proportional so

ΔLSR ≅ ΔLNM by Side-Side-Side Similarity Theorem

The distribution of SAT scores of all college-bound seniors taking the SAT in 2014 was approximately normal with a mean of 14971

lora16 [44]

Answer:

P ( X > 1800) = 0.1734

Step-by-step explanation:

Given:-

- The mean, u = 1497

- The standard deviation, s.d = 322

Find:-

P(X>1800)

Solution:-

- We will denote a random variable X that follows a normal distribution for the SAT scores in 2014 with parameters mean (u) and standard deviation (s.d) as follows:

X ~ N ( 1497 , 322 )

- The following probability can be calculated by first computing the Z-score value:

P ( X < x ) = P ( X < Z )

Where,

Z = ( x - u ) / s.d

- P(X > 1800) have the corresponding Z-score value:

Z = ( 1800 - 1497 ) / 322

Z = 0.941

- Hence, using Z-table:

P ( X > 1800) = 1 - P ( Z < 0.9471 )

P ( X > 1800) = 1 - 0.8266

P ( X > 1800) = 0.1734
