#2) ratio 3:4 = 15:20

L = 15
W = 20

double check

A = L x W
A = 15x20
A = 300

A 99% confidence interval for the difference between two proportions was estimated at 0.11, 0.39. Based on this, we can conclude
sladkih [1.3K]

Answer:

\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE

And for this case the confidence interval is given by:

0.11 \leq p_1 -p_2 \leq 0.39

Since the confidenc einterval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal

Step-by-step explanation:

Let p1 and p2 the population proportions of interest and let \hat p_1 and \hat p_2 the estimators for the proportions we know that the confidence interval for the difference of proportions is given by this formula:

\hat p_1 -\hat p_2 \pm z_{\alpha/2} SE

And for this case the confidence interval is given by:

0.11 \leq p_1 -p_2 \leq 0.39

Since the confidence interval not contains the value 0 we can conclude that we have significant difference between the two population proportion of interest 1% of significance given. So then we can't conclude that the two proportions are equal

What is the missing justification in the proof?
nataly862011 [7]
The missing justification in the proof is
<span>B) Substitution property of equality

The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.

Can u Simplify this problem???!? 3t-7t+14t
sleet_krkn [62]
Come on now, Tayala !

What if I say to you:
"Start with 3 cows, take away 7 cows, and then add 14 cows. How many are there ?"

Don't let the little 't' scare you.  It doesn't matter one bit what 't' really is.  It can be
a number, a teacher, a tiger, or a teacup.  Whatever it is, you start with 3 of them,
take away 7 of them, and then add on 14 of them.  How many are there ?

Hint:  If there are not ten of them, then go back and look at the cows again.
