Answer:

c) T(−1, 3) ° Rotation,180°

Step-by-step explanation:

<u><em>Explanation:</em></u><em>-</em>

<em>First we will apply transformation is </em>

<em>Rotation of 180°  then we will apply transformation is changes  </em>

<em>(x,y) to (-x ,-y)</em>

<em>a)</em>

<em>Given vertex T(  2 ,2 )</em>

<em>T( 2 ,2 )→ T( -2 ,-2)</em>

<em>Next we will apply rule </em>

<em>Horizontal translation left '1' units and Vertical translation up 'd' units</em>

<em>T( -2 ,-2) → T¹ ( -2 -1 ,-2 +3)</em>

<u><em>The new vertex is  T¹ ( -3 ,1)</em></u>

<em>b)</em>

<em>Given vertex U(  4 ,2 )</em>

<em>U( 4 ,2 )→ U( -4 ,-2)</em>

<em>Next we will apply rule </em>

<em>Horizontal translation left '1' units and Vertical translation up 'd' units</em>

<em>U -4 ,-2) → U¹ ( -4 -1 ,-2 +3)</em>

<u><em>The new vertex is  U¹ ( -5 ,1)</em></u>

<em>c) </em>

<em>Given vertex R(  3 ,5 )</em>

<em>R( 3 ,5 )→ R( -3,-5)</em>

<em>Next we will apply rule </em>

<em>Horizontal translation left '1' units and Vertical translation up 'd' units</em>

<em>R( -3 ,-5) → R¹ ( -3 -1 ,-5 +3)</em>

<u><em>The new vertex is  R¹ ( -4 ,-2)</em></u>

<em>d) </em>

<em>Given vertex S(  1 ,3 )</em>

<em>S( 1 ,3 )→ S( -1 ,-3)</em>

<em>Next we will apply rule </em>

<em>Horizontal translation left '1' units and Vertical translation up 'd' units</em>

<em>S( -1,-3) → S¹ ( -1 -1 ,-3 +3)</em>

<u><em>The new vertex is  S¹ ( -2,0)</em></u>

sergiy2304 [10]

Answer:

\frac{ {b}^{10} }{ 81 {a}^{2} }

Step-by-step explanation:

(9ab^{-5})^{-2} \\  \\  =  {9}^{ - 2}  {a}^{ - 2}  {b}^{ - 5( - 2)} \\  \\  =  {9}^{ - 2}  {a}^{ - 2}  {b}^{10}  \\  \\  =  \frac{ {b}^{10} }{ {9}^{2}  {a}^{2} }  \\  \\  \huge =  \frac{ {b}^{10} }{ 81 {a}^{2} }

(Hypothetical.) Suppose five measurements of the volume of a liquid yield the following data (in milliliters).
ElenaW [278]

Answer:

(48.106 ; 53.494)

Step-by-step explanation:

Given the data:

X : 52 48 49 52 53

Sample mean = ΣX / n

n = 5

Sample mean, xbar = 254 / 5 = 50.8

Standard deviation, s = 2.17 (using calculator)

The standard error (SE) : s/√n =2.17/√5 = 0.970

The degree of freedom, df = n-1

df = 5 - 1 = 4

Tscore(0.05, 4) = 2.776

Confidence interval :

Xbar ± Tscore*standard error

50.8 ± (2.776 * 0.970)

50.8 ± 2.694

Lower boundary = 50.8 - 2.694 = 48.106

Upper boundary = 50.8 + 2.694 = 53.494

(48.106 ; 53.494)
