Eduardwww [97]

Answer:

$6.25$

Step-by-step explanation:

$We\ are\ given:\\Observations\ in\ the\ Set=(7,5,4,9)\\ As\ we\ know\ that,\\ Average\ or\ interchangeably\ mean=\frac{Total\ Sum\ of\ observations }{Total\ no.\ of\ observations} \\Here,\\Total\ sum\ of\ the\ observations=7+5+4+9=25\\Total\ number\ of\ observations=4\\Hence\ here,\\Mean/Average=\frac{25}{4}=6.25$

Simplify the expression please

Alinara [238K]

Answer:

Step-by-step explanation:

$(\frac{7t^{\frac{-1}{4}}}{16t})^{2}=\frac{7t^{\frac{-1}{4}*2}}{16t^{2}}\\\\=\frac{7t^{\frac{-1}{2}}}{16t^{2}}\\\\=\frac{7}{16t^{2+\frac{1}{2}}}\\\\\frac{7}{16t^{\frac{5}{2}}}$

Solve for AB. Round your answer to the nearest tenth if necessary.

11111nata11111 [884]

Answer:

AB = 55.25

Step-by-step explanation:

Set up an equation where the length of AB is equal to AC minus BC. This will allow us to solve for x, and then the length of AB.

AB = AC - BC

5x + 9 = 87 - (3x + 4)

5x + 9 = 87 - 3x - 4

5x + 9 = 83 - 3x

8x + 9 = 83

8x = 74

x = 9.25

Now plug 9.25 in for x in the equation for AB

AB = 5x + 9

AB = 5(9.25) + 9

AB = 46.25 + 9

AB = 55.25
