Can I get help solve to find X?
Taya2010 [7]
<h3>Answer:  x = 14</h3>

==========================================

Explanation:

The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.

All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.

Set 2x+32 equal to 60 and solve for x

2x+32 = 60

2x = 60-32

2x = 28

x = 28/2

x = 14

As a check,

2x+32 = 2*14+32 = 28+32 = 60

which helps confirm the answer.

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test
SSSSS [86.1K]

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."

<h3>What is F-statistics?</h3>

An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.

Some key features regarding the F-statistics are-

  • It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
  • When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
  • A significant result does not imply that all of your variables have been significant.
  • The statistic is simply comparing the cumulative influence of all the variables.
