We have our equation set up for us:

46-46*x=20

move 20 to the other side an then subtract

46*x=26

divide 46 on both sides

x = 26/46

simplify

x=

13/23 which is around

0.56521..

<h2><u><em>Rounded, the percentage decrease is </em></u></h2><h2><u><em></em></u></h2><h2><u><em>56.5 percent</em></u></h2>

<u><em></em></u>

Assume that all conditions are met. The mean of the differences was 1. 33 and the standard deviation of those differences was 2.
Maurinko [17]

The test statistic for this procedure is using two sample T-test is 0.458.

Definition of Two Sample T-test

A variation of the Student's t-test used to determine if two sample means are substantially different is known as the two sample T-test (also known as Welch's t-test, Welch's adjusted T, or unequal variances t-test). The test's degrees of freedom have been changed, which generally boosts the test's power for samples with unequal variance.

T-Test Statistic for The Procedure

It is given that mean of the differences = 1.33

And, the standard deviation of the differences, standard error = 2.90

The test static formula is given as,

t = (estimate - hypothized value) / standard error

Here,  t is the t- test statistic, and estimate is the mean of the differences.

Since it is given that all conditions are met, the hypothized value can be taken as 0

Substituting substituting estimate = 1.33 and standard error = 2.90 in the t-test statistic formula, we get,

t = (1.33-0)/2.90

or t = 0.458

Three exterior angles of a pentagon measures 60,80and 90.Find the measure of other two exterior angle, assuming them equally Tha
julsineya [31]

Given:

The three exterior angles of a pentagon measures 60,80 and 90.

To find:

The measure of other two exterior angle, assuming them equally.

Solution:

Let x be the measure of two other exterior angles of the pentagon.

We know that the sum of all exterior angles of a pentagon is 360 degrees.

60^\circ+80^\circ+90^\circ+x+x=360^\circ

230^\circ+2x=360^\circ

2x=360^\circ-230^\circ

2x=130^\circ

Divide both sides by 2.

\dfrac{2x}{2}=\dfrac{130^\circ}{2}

x=65^\circ

Therefore, the measures of both exterior angles are 65 degrees.
