Step-by-step explanation:

You must place in the question sign box the value of x that is above the question sign box because you are trying to fill out the y row.

Example: y=[tex]-\frac{0}{3} +2[/tex]= -0+2=2

Answer:

Step-by-step explanation:

tip:

plug the x values from the table ( the top row values ) into the equation

in this case its 0

BOX 1:

[tex]-\frac{0}{3} +2\\[/tex]

0 divided by anything = 0

so, 0 + 2 = 2

box 1 = 2

BOX 2:

[tex]-\frac{3}{3} +2[/tex]

3 div by 3 = 1 ( in this case negative 1 )

so, -1 + 2 = 1

box 2 = 1

BOX 3:

[tex]-\frac{6}{3} +2[/tex]

6 div by 3 = 2 ( in this case negative 2)

-2 + 2 = 0

box 3 = 0

Answer:

0.37

Step-by-step explanation:

To resolve the given problem we will apply

persistent time Markov chain :   n = 0, 1, . . . , 4

 n = number of individuals pausing

where The equalization conditions are : πn = ( πn - 1/2 )

Given that  :

n = 0,1,2,3,4

π0 = 1/( 1 + 2−1 + 2−2 + 2−3 + 2−4) = 0.52 = 16/31

Also the normal number of travelers found by Ella will be represented as

E(N) = (π1 + 2π2 + 3π3) / ( π0 + π1 + π2 + π3) ------- ( 1 )

where : π1 = 8,  π2 = 4,  π3 = 2 , π0 = 16/31  input values into equation 1

E ( N ) =  22/30

given that the True to form hanging tight time = 0.5

hence Holding holding time = E(N ) * 0.5

therefore  the expected waiting time for Ella = ( 22/30 ) * 0.5 = 0.37

Decimal numbers are number that contains decimal points. The value  123.7561 rounded to nearest hundredth is 123.76

Decimal numbers are number that contains decimal points in between the values.

Given the decimal value 123.7561, we are to convert the decimal values to the hundredth place.

This means that there must only be two values after the decimal points and the values rounded up if greater than 4.

Hence the value  123.7561 rounded to nearest hundredth is 123.76

Step-by-step explanation:

Remeber it's the half of the number (N).

The  slope of the table below? 3/8 15/12 9/10 0/7 is 23.8

Slope is defined as the rate of change of y with respect to x.  Invariably, it it the rise in y over the run  in x. put differently, slope is increase over increase in x

The slope of a line is defined

S= (increase in y)/(Increase in x) = Δy/Δx

Slope = (0/7 - 18/12) ÷ (9/10 -3/8)

Slope = 15/12 ÷ 42/80

Simplify the fractions to have

Slope = 15/12 * 80/42

The slope = 1200/504

Slope of the table is given as 23.4

Conclusively, the table gives us a slope approximately 23

Answer:

l = t/4v² - 1

Step-by-step explanation:

Given the expression

v = √l+t/2√l

We are to make l the subject of the formula as shown;

Cross multiply

2v√l =  √l+t

Square both sides

(2v√l)² =  (√l+t)²

4v²l = l+t

t = 4v²l - l

t = l(4v² - 1)

Divide both sides by 4v² - 1

t/4v² - 1 = l(4v² - 1)/4v² - 1

t/4v² - 1 = l

Swap

l = t/4v² - 1

Hence the required expression for l is t/4v² - 1

Point-slope form:

Use the point-slope form to find the equation and then convert it to slope-intercept form:

Answer:

(507.05, 592.95)

Step-by-step explanation:

Given data:

sample mean = $550, sample standard deviation S = $60.05

95% confidence interval , n = 10

For 95% confidence interval for the mean

mean ± M.E.

where M.E. is margin of error = [tex]t_{n-1}, \alpha/2\times\frac{S}{\sqrt{n} }[/tex]

Substituting the values in above equation

[tex]=t_{10-1}, 0.05/2\times\frac{60.05}{\sqrt{10} }[/tex]

The value of hydronium ion concentration in the vinegar is 3.162×10^-3 (optionD)

pH is defined as the negative log of the hydrogen ion concentration. The range of pH extends from zero to 14. A pH value of 7 is neutral, because pure water has a pH value of exactly 7.

pH can also be defined as the measure of acidity and alkalinity of a substance.

pH = –log(H+)

Therefore (H+) = 10^-(pH)

For a pH of 2.5, the hydronium ion concentration

= 10^-2.5

(H+) = 0.003162 = 3.162×10^-3

Therefore hydronium ion concentration of the vinegar is 3.162×10^-3

Step-by-step explanation:

Given:

The line through (6, −3) and (7, 6) is perpendicular to the line through (−2, 5) and (x, −1).

To find:

The value of x.

Solution:

Slope formula: If a line passes through two points, then the slope of the line is:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The slope of the line through (6, −3) and (7, 6) is:

[tex]m_1=\dfrac{6-(-3)}{7-6}[/tex]

[tex]m_1=\dfrac{6+3}{1}[/tex]

[tex]m_1=9[/tex]

The slope of the line through (−2, 5) and (x, −1) is:

[tex]m_2=\dfrac{-1-5}{x-(-2)}[/tex]

[tex]m_2=\dfrac{-6}{x+2}[/tex]

We know that the product of slopes of two perpendicular lines is -1.

[tex]m_1\cdot m_2=-1[/tex]

[tex]9\cdot \dfrac{-6}{x+2}=-1[/tex]

[tex]\dfrac{-54}{x+2}=-1[/tex]

Multiplying both sides by (x+2), we get

[tex]-54=-1(x+2)[/tex]

[tex]-54=-x-2[/tex]

[tex]-54+2=-x[/tex]

[tex]-52=-x[/tex]

Divide both sides by -1.

[tex]52=x[/tex]

Therefore, the value of x is 52.
