Can someone please help me

Answer:

  8.0 units

Step-by-step explanation:

The law of sines tells you ...

  AB/sin(C) = AC/sin(B)

  AB = sin(C)/sin(B)×AC . . . . . . multiply by sin(C)

  AB = sin(53°)/sin(44°)×7 ≈ 8.048

The length of AB is about 8.0 units.

Answer:

CE = 7.2

Step-by-step explanation:

Area = 1/2bh

6 = 1/2 (b)(4)

6 = 2b

3 = b     b represent AB, so BC and CD is 3 unit also

Length of CE , you have a right triangle with a leg(AE) = 4 and and the other leg (AC) = 6 and the hypotenuse (CE) = x

The figure is a right triangle so you know that a² + b² = c²

4² + 6² = x²

16 + 36 = x²

52 = x²

[tex]\sqrt{52 }[/tex] = x

7.211 ≈ 7.2 = CE

Answer:

x=12

Step by step explanation:

Let's solve your equation step-by-step.

2x+3=x+15

Step 1: Subtract x from both sides.

2x+3−x=x+15−x

x+3=15

Step 2: Subtract 3 from both sides.

x+3−3=15−3

x=12

=>x=12

The variance of [6 ,7 ,10 ,11 ,12 ,13 ,16 ,18 ,25] is 34.61

The sample size (n) = 9

The mean of the distribution (x_i) is the sum of the distribution divided by the number of items in the distribution.

[tex]\mathbf{x_i=\dfrac{6+7+10+11+12+13+16+18+25}{9}}[/tex]

[tex]\mathbf{x_i=\dfrac{118}{9}}[/tex]

[tex]\mathbf{x_i=13.11}[/tex]

The variance  is the average between the difference of the mean, followed by squaring the result.

[tex]\mathbf{S^2 = \dfrac{\sum (x_i - \bar x)^2}{n-1}}[/tex]

[tex]\mathbf{S^2 = \dfrac{ ((6 -13.11)^2+ (7-13.11)^2+...+(16-13.11)^2+(18-13.11)^2+(25-13.11)^2}{8}}[/tex]

[tex]\mathbf{S^2 = \dfrac{276.8889}{8}}[/tex]

[tex]\mathbf{S^2 = \ 34.61}[/tex]

Therefore, the variance of the sample given is 34.61

Answer:

  60°

Step-by-step explanation:

If the measure of the angle is represented by A, then the sum of the three angles in the triangle is ...

  A +A +A = 180°

  3A = 180° . . . . . . . simplify

  A = 180°/3 = 60° . . . . . divide by the coefficient of A

The three angles in an equi-angular triangle are all 60°.

__

Additional comment

If the angles are equal, so are the opposite sides. The three sides in an equi-angular triangle are also equal. Generally, such a triangle is called an equilateral triangle. It is useful to remember the angles in an equilateral triangle are all 60°.

One interesting consequence of this is that the smallest angle in any triangle can never be larger than 60°.
