<h3>Answer: 12.5 (choice C)</h3>

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

We apply the pythagorean theorem to find this answer.

a = 11 and b = 6 are the given legs

c = unknown hypotenuse

So,

a^2+b^2 = c^2

c = sqrt( a^2+b^2 )

c = sqrt( 11^2 + 6^2 )

c = sqrt( 121 + 36 )

c = sqrt( 157 )

c = 12.52996 approximately

c = 12.5

Side note: once you replace 'a' and b with 11 and 6, you can compute everything with a calculator in one single step more or less. The steps above are shown if you wanted to find the exact value sqrt(157).

Identify the pattern.Write the next 3 terms in each sequence. 83,75,67,59...

ExtremeBDS [4]

The pattern is the subtract 8 from the previous number.

So the next number: 59 - 8 = 51

And the next: 51 - 8 = 43

And the next: 43 - 8 = 35

As notas de dois alunos X e Y estão representadas no quadro abaixo. Por meio da variância, qual deles apresentou ser o mais regu

Reil [10]

Answer:

Aluno X

Step-by-step explanation:

A nota média para os alunos X e Y são, respectivamente:

$X_m=\frac{5+3+5+7}{4}=5 \\Y_m=\frac{4+9+4+3}{4}=5$

A variância é definida pela seguinte expressão:

$V=\frac{\sum(X_i-X_m)^2}{n-1}$

Onde n é o numero de termos, neste caso, n = 4.

As variâncias para cada aluno são:

$V_x=\frac{(5-5)^2+(3-5)^2+(5-5)^2+(7-5)^2}{4-1} \\V_x= 2.7\\V_y=\frac{(4-5)^2+(9-5)^2+(4-5)^2+(3-5)^2}{4-1} \\V_y= 7.3$

O aluno X apresentou uma variância menor do que o aluno Y em suas notas e, portanto, apresentou ser o mais regular.

How long is the arc intersected by a central angle of 5pie/3 radians in a circle with a radius of 2ft rounded to the nearest ten

lubasha [3.4K]

Radius of a circle: r = 2 ft
Central angle: α = 5 π /3 = 300°
Arc Length = 2 · 2 · π · 300/360 = 2 · 2 · 3.14 · 5/6 = 10.4666 ft ≈ 10.5 ft
Answer:
C ) 10.5 ft
