Is -100 rational or irational

Mathematics

pychu [463]2 years ago
4 0

-100 is rational.

-100 can be turned into a fraction by doing the following...

Just put 1 underneath -100 and you get \frac{-100}{1}

So that means it is rational since it can be a fraction!

The SAT is standardized to be normally distributed with a mean µ = 500 and a standard deviation σ = 100. What percentage of SAT
Aliun [14]

Answer:

34.134%

68.268%

Step-by-step explanation:

Given that:

Mean (m) = 500

Standard deviation (s) = 100

Percentage between 500 and 600

P(500 < x < 600)

P(x < 600) - P(x < 500)

Z = (x - m) / s

P(x < 600)

Z = (600 - 500) /100 = 1

P(x < 500)

Z = (500 - 500) / 500 = 0

P(Z< 1) - P(Z < 0)

0.84134 - 0.5

= 0.34134

= 0.34134 * 100%

= 34.134%

B.) Between 400 and 600

P(x < 400)

Z = (400 - 500) /100 = - 1

P(x < 600)

Z = (600 - 500) / 500 = 1

P(Z< 1 ) - P(Z < - 1)

0.84134 - 0.15866

= 0.68268

= 0.68268 * 100%

= 68.268%

Tell how to multiply two fractions give an example
mario62 [17]
Ex 1:
2/5 x 4/5
Multiply both the numerators together and then multiply both the denominators together. You would multiply 2x4 which is 8 and 5x5 which is 25. Which leaves you with 8/25 and it will stay that way because you cannot simplify it further.

Ex 2:
2/5 and 5/3
Multiply across 2x5/5x3 and you end up with 10/15 which can be simplified/reduced to 2/3 because they share a common factor of 5.

Find the equation of the line with Slope = 6 and passing through (5,38). Write your equation in the form y =mx+b
laiz [17]

Hello.

We have:

  • A point that the line passes through
  • The slope of the line

Plug the values into the Point-Slope Formula:

\mathrm{y-y_1=m(x-x_1)}

\mathrm{y-38=6(x-5)}

\mathrm{y-38=6x-30}

\mathrm{y=6x-30+38}

\Large\boxed{\sf{ \ y=6x+8}}

I hope it helps.

Have a nice day.

Louis’s bill from dinner at a restaurant is $27.62 before tax. The local tax rate is 7.5%. Louis would like to leave a 20% tip o
shtirl [24]
As Louis is only leaving a 20% tip on the pretax bill, this means he's leaving 20% of $27.62
The best thing to do is to find 10% and double it.
27.62/10= 2.76 (as it rounds down)
2.76*2= 5.52
Therefore, you've got to add $5.52 to $27.62
$5.52+$27.62= $33.14
Hope this helps :)
