Crazy boy [7]

Answer:One can do a two-proportion test and find that the z-value for different is 1.28 (or -1.28, depending how one sets up the test).

The p-value for that is 0.20, so by most tests this is not statistically significant.

 

Said another way, if there had been no change in the interval, the probability of having a repeat sample at least this different would be 0.20.

The parameter one is attempting to determine is the true proportion of adults in the US who say they like pizza.

For those who think it is 50%, it is essentially 100% likely that it is not 50% but much higher, around 75-77%.

Factor each expression 16x+40y
prohojiy [21]
Hi there!

To factor this expression, you must first find the greatest common factor of each term, 16x and 40y.

To do this, first list the factors of each coefficient since they do not share any variables:
16:1,2,4,8,16
40:1,2,4,5,8,10,20,40

Notice that among the factors of each term, 8 is the greatest common factor.

Finally, factor 8 from the expression to get 8(2x+5y) as your final answer.

Hope this helps, and have a nice day!

Answer:

  • x = - 9

Step-by-step explanation:

<u>In order to find the vertical asymptotes make the denominator equal to zero and solve:</u>

  • 2x + 18 = 0
  • 2x = - 18
  • x = - 9

There is one vertical asymptote since the denominator is linear expression
