Answer:

Both Ryan and Fransisco started off with equivalent expressions. this expression was x^ 1/3.

Step-by-step explanation:

Fransisco simplified (x^ 1/2) / (x^ 3/18).  

He ended up with x^ 1/3 (x to the 1/3 power) by doing (x^1/2) / (x^3/18) by subtracting the powers x^(1/2 - 3/18). x^(1/2 - 3/18) can be converted to x^(9/18 - 3/18) to get the denominators the same. Then subtract to get x^ 6/18 which simplifies to x^ 1/3.  

Ryan simplified 27√ x^2 . x^3 . x^4.  

Step one is to combine the powers. Since all of the variables inside of the radical are the same, they can be combined into one term by adding the exponents. This makes the equation 27√x^9. In order to put it into the correct form, you must make the 27 the denominator and 9 the numerator in the exponent. This makes the expression x^ (9/27), which can be simplified to x^ 1/3.  

Both Ryan and Fransisco started off with equivalent expressions. this expression was x^ 1/3.

If u={a,b,c,d}and p={b,d,e}find p(bar at the top)
san4es73 [151]

Answer:

{a , c}

Step-by-step explanation:

first find u intersection p

n(U n P ) = {a , b , c , d} n {b , d , e}

={d , b}

intersection means element or values which lies in both the sets

now to find p complement

note : p( bar at the top ) is read as p complement

p complement = n(U) - n(U n P)

={a , b , c , d} - {d , b}

={a , c}

n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)

You are a screenwriter who is writing a script for an hour-long police drama. You have written 20 1/2 pages for act 1 and 5 1/2
finlep [7]

Answer:

You have written 26 pages in total.

Step-by-step explanation:

I always enjoyed adding fractions. Something about it is so... <em>simple.</em>

<u>The problem is basically asking us to add 20 1/2 and 5 1/2 together.</u>

I would first suggest adding both halves together, to make 1.

That way, we're left with 20 + 5 + 1. That seem easier, doesn't it?

Then we would add 20, 5 and 1 together, to get 26 whole pages.

And that, to an extent, is how I did it.

Hope this helps! :D

Readme [11.4K]

Answer:

First you need to find the slope of the line:

m=6-(-2) / (-1)-0 =-8

equation of line is:

y=mx+b

y=-8x+6

for absolute value function:

if x<0

y=-8x+6

if x>0

y=+8x-6

There are big spenders among University of Alabama football season ticket holders. This data set Roll Tide!! shows the dollar am

Using the z-distribution, as we have a proportion, the 95% confidence interval is (0.2316, 0.3112).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

In this problem, we have a 95% confidence level, hence\alpha = 0.95, z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96.

We also consider that 130 out of the 479 season ticket holders spent $1000 or more at the previous two home football games, hence:

n = 479, \pi = \frac{130}{479} = 0.2714

Hence the bounds of the interval are found as follows:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2714 - 1.96\sqrt{\frac{0.2714(0.7286)}{479}} = 0.2316

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2714 + 1.96\sqrt{\frac{0.2714(0.7286)}{479}} = 0.3112

The 95% confidence interval is (0.2316, 0.3112).
