The Answer of x is 112.1
This is because all the angles sit on a 180 degree line so all the points have to add up to 180.
180-67.9=112.1

Find the slope of the line through each pair of points.<br><br> (19, −2), (−11, 10)
Stels [109]

Answer:

slope = -\frac{2}{5}

Step-by-step explanation:

1) Calculate the slope using slope formula, \frac{y_2-y_1}{x_2-x_1}. Use the two points given, substitute their x and y values into the formula, and solve.

\frac{(10)-(-2)}{(-11)-(19)} \\= \frac{10+2}{-11-19} \\= \frac{12}{-30}\\= -\frac{2}{5}

Thus, the slope is -\frac{2}{5}.

Tristan is 22 years younger than Sydney. 8 years ago, Sydney's age was 2 times Tristan's age. How old is Tristan now?
Serjik [45]

Answer:

Sydney is 52 years old, and Tristan is 30.

Step-by-step explanation:

Represent Tristan's age by t and Sydney's by s.

Then s - 8 = 2(t - 8), and t = s - 22

Substituting s - 22 in the first equation, we get:

s - 8 = 2(s - 22 - 8), or

s - 8 = 2s - 60

Solving for s:  -2s + s = -60 + 8, or -s = -52.

Sydney is 52 years old, and Tristan is 30.

Which of the following random variables is not discrete?
Ilia_Sergeevich [38]

Answer:

b) The annual rainfall in a city

Step-by-step explanation:

Remember, a discrete variable is one that can only take a finite number of values between any two values of a characteristic and a continuous variable is one that can take an infinite number of values between any two values of a characteristic.

a) Observe that the variable x='<em>classes taken in one semester' </em>can take the values 0,1,2,...,n.

Then the variable x is discrete

b) Observe that the variable x='<em>annual rainfall in a city'</em> can take the values 2in, 1.6in, 5.1 in, 0.1in

Then, the variable x can be take a infinite number of values between two number. So x isn't a discrete variable.

c) The variable x=<em>'attendance at a football game' </em>can take the values 3000,5000... n. And never will be a decimal number because There cannot be a personal decimal number. Therefore, x is a discrete variable.

d) The variable x='<em>patients treated at an emergency room in a day</em>' can take the values 1,2,3,...,n. And never will be a decimal number because There cannot be a personal decimal number. Therefore, x is a discrete variable.
