Answer:

dy/dx=sec^2^(x)-(-csc^2(x)

=sec^2(x)+ csc^2(x)

so solution is E

The value of the standardized test statistic for this significance test is 1.7265

Standardized test statistic

In statistics, the standardized test statistic means a way for you to compare your results to a “normal” population.

Given,

A city ordinance requires that more than 75% of its residents must agree to the construction of new public buildings (using tax dollars) before any such structures can be built. a proposal has been made to build a new recreational facility in the city, and sponsors of the proposal want to conduct a small survey to see if it would be approved if put to an official vote of all residents. a simple random sample of 150 residents revealed that 123 supported a change (and 27 did not).

Here we need to find the value of the standardized test statistic for this significance test.

While we looking into the given question we have identified the following values,

Random samples = 150

Supported values = 123

Not supported = 23

Aggreged percentage = 75%

So, the null and alternative hypotheses were as follows: H0: p = 0.75 and Ha: p ≠ 0.75.

Then the value of Standardized test statistic is calculated as,

=> (150 - 123) / (75 / √23)

=> 1.7265

Find the slope of the line passing through (1,3) and (-2,5)
Alenkasestr [34]

Hi there! :)

Step-by-step explanation:

Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}

\frac{5-3}{(-2)-1}=\frac{2}{-3}

<u><em>Slope is -2/3</em></u>

<u><em>Final answer is -2/3</em></u>

Hope this helps!

Thanks!

-Charlie

Have a nice day! :)

What is the slope between these 2 points?
Art [367]

Answer:

b

Step-by-step explanation:

y2-y1/x2-x1

memorize this formula so you always know slope for 2 points given.

y is the second number in parentheses.

whichever you choose as y2 or y1, the x values will match those numbers as well.

(y2-y1) = (1-5)

(x2-x1) = (2+4)

(-4)/6

-2/3
