Answer:
We are confident that the true proportion of people satisfied with the quality of education the students receive is between (0.3995, 0.4564), since the lower value for this confidence level is higher than 0.38 we have enough evidence to conclude that the parents' attitudes toward the quality of education have changed.
Step-by-step explanation:
For this case we are interesting in the parameter of the true proportion of people satisfied with the quality of education the students receive
The confidence level is given 95%, the significance level would be given by
and
. And the critical values are:
The estimated proportion of people satisfied with the quality of education the students receive is given by:

The confidence interval for the proportion if interest is given by the following formula:
And replacing the info given we got:
We are confident that the true proportion of people satisfied with the quality of education the students receive is between (0.3995, 0.4564), since the lower value for this confidence level is higher than 0.38 we have enough evidence to conclude that the parents' attitudes toward the quality of education have changed.
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is
.
We need to find the factor of this trinomial.

The factors of
is (x-2) and (x-8).
So, the factor of
is (x-8). Hence, the correct option is (B).
Since you answered the first 2 i can go to c and d.
C can really be anything since it's being multiplied by 0 no matter what you put there it will be 0.
But for D it's 1/10^2
Hope this helps ^^

Answer: 81</h3>
Work Shown:
x = number of cats
(4 cats)/(5 dogs) = (x cats)/(45 dogs)
4/5 = x/45
4*45 = 5x
180 = 5x
5x = 180
x = 180/5
x = 36
There are 36 cats and x+45 = 36+45 = 81 cats and dogs total.
