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

Answers

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

What is slope?

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

Solve for l:
[tex]v = \frac{ \sqrt{l + t} }{2 \sqrt{l} } [/tex]
.....​

Answers

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

What is the gravitational potential energy of a 55-kg person that has climber a 4,000 meter tall mountain?

Bonus: if one snickers bar is 1,100,000 joules of energy, how many snickers bars would provide enough fuel to climb the mountain ?

Answers

Answer:

2156000 J.

Bonus: 2 snickers bar

Step-by-step explanation:

Applying

P.E = mgh................. Equation 1

Where P.E = Gravitational potential energy, m = mass of the person, h = height of the mountain, g = acceleration due to gravity.

From the question,

Given: m = 55 kg, h = 4000 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

P.E = (55×4000×9.8)

P.E = 2156000 J.

If one snikers bar is 1100000 J of energy,

Then, (2156000/1100000) snickers bar would be enough to climb the mountain

Number of snickers bar =  (2156000/1100000)  = 1.96 ≈ 2

The hundredth place is the second digit after the decimal. So 5 would be the hundredth place right now. Take a step to the thousandth place and see if the number is greater or less than 5 to determine if you should round up or round down. 6 is greater than 5, round up.
The answer is 123.76

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

Rounding of decimal numbers

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

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

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]

so, -1 + 2 = 1

box 2 = 1

-2 + 2 = 0

A reporter for a student newspaper is writing an article on the cost of off-campus housing. A sample was selected of 10 one-bedroom units within a half-mile of campus and the rents paid. The sample mean is $550 and the sample standard deviation is $60.05. Provide a 95% confidence interval estimate of the mean rent per month for the population of one-bedroom units within a half-mile of campus. Assume that population is normally distributed.

Answers

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]

= 2.62×18.99

=42.955

Answers

Answer:

y = - 4x - 15

---------------------------

Slope-intercept form:

y = mx + b, where m is the slope, b is the y-intercept

Point-slope form:

y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point on the line

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

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

What is pH?

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

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

Answers

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.

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
