Answer:

value of a = 6.93 m

hence , (b.)

Step-by-step explanation:

the given triangle is a right angled triangle, so

by using trigonometry.

=》

\tan(a)   = \tan(30)  =  \frac{1}{ \sqrt{3} }

and we know,

=》

\tan(a)  =  \frac{a}{b}

so, by above values of tan ( a ) we get,

=》

\frac{a}{b}  =  \frac{1}{ \sqrt{3} }

=》

\frac{a}{12}  =  \frac{1}{ \sqrt{3} }

=》

a = \frac{12}{ \sqrt{3} }

=》

a = 4 \sqrt{3}

=

=》

a = 6.93

hence, a = 6.93 m

Romashka [77]

Answer:

The most appropriate statistical test to use to compare the mood scores from the different groups is independent sample t-test.

Step-by-step explanation:

The Independent Samples t-test examines the means of two independent groups to see if statistical evidence exists to show that the related population means differ significantly.

The Independent Samples t-test is also known as Independent t-test, Independent Two-sample t-test, and among others.

It should be note that only two (and only two) groups can be compared using the Independent Samples t-test. It is not possible to use it to make comparisons between more than two groups.

Therefore, the most appropriate statistical test to use to compare the mood scores from the different groups is independent sample t-test.

Please help! I need the surface area for both. Absurd answer are not tolerated. Thanks if you help!
Natasha_Volkova [10]

Answer:

<h3>Figure 1</h3>
  • Perimeter of base = 5 + 5 + 8 = 18 ft
  • Height = 7 ft
  • Base area = 1/2(8)(3) = 12 ft²

<u>Surface area:</u>

  • S = 18*7 + 2*12 = 150 ft²
<h3>Figure 2</h3>

<u>Surface area of cube:</u>

  • S = 6a² = 6(2.5)² = 37.5 m²

<u>Surface area of prism:</u>

  • S = 2(11 + 9)(7) = 280 m²

<u>Overlapping area:</u>

  • S = 2.5² = 6.25 m²

<u>Surface area of composite figure:</u>

  • S = 280 + 37.5 - 2(6.25) = 305 m²
