<h3>Answers:</h3><h3>x = 4</h3><h3>z = 61</h3>

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

Work Shown:

The left and right angles (119 and 9x+83) are vertical angles.

Therefore, they are congruent or equal angles.

9x+83 = 119

9x = 119-83 ..... subtract 83 from both sides

9x = 36

x = 36/9 .... divide both sides by 9

x = 4

--------

To find the value of z, we take advantage of the fact that angles 119 and z are supplementary. They add to 180 degrees.

z+119 = 180

z = 180-119 .... subtract 119 from both sides

z = 61

The odds that it will snow tomorrow are 9 to 6. What is the probability that it will not snow tomorrow?a) 0.1818
kolezko [41]

Answer:

a) 0.1818

Step-by-step explanation:

Given that:

The odd that it'll snow tomorrow is 9 to 6

The probability that it will snow tomorrow  =\dfrac{9}{9+6}

=\dfrac{9}{15}

= 0.6

The probability that it'll not snow tomorrow = 1 - \dfrac{9}{15}

= \dfrac{15-9}{15}

=\dfrac{6}{15}

= 0.4

Let assume that the odd that it'll snow tomorrow is 9 to 2

The probability that it will snow tomorrow  =\dfrac{9}{9+2}

=\dfrac{9}{11}

= 0.8181

The probability that it'll not snow tomorrow  = 1 - \dfrac{9}{11}

= \dfrac{11-9}{11}

=\dfrac{2}{11}

= 0.1818

What is dy/dx if y = (x2 + 2)3(x3 + 3)2? A. 3(x2 + 2)2(x3 + 3)2 + 2(x2 + 2)2(x3 + 3) B. 2x(x3 + 3)2 + 3x2(x2 + 2)3 C. 6x(x2 + 2)
Vlada [557]
We want to find \displaystyle{  \frac{dy}{dx}, for

            \displaystyle{ y=(x^2+2)^3(x^3+3)^2.

Recall the product rule: for 2 differentiable functions f and g, the derivative of their product is as follows:

                                  (fg)'=f'g+g'f.

Thus,

 y'=[(x^2+2)^3]'[(x^3+3)^2]+[(x^3+3)^2]'[(x^2+2)^3]\\\\ =3(x^2+2)^2(x^3+3)^2+2(x^3+3)(x^2+2)^3

Answer: A)      3(x^2+2)^2(x^3+3)^2+2(x^3+3)(x^2+2)^3.
