You have to isolate the variable. Get the variable on one side of the equals sign, by itself and the number on the other side will be what number the variable is equivalent to. You do this by canceling out the numbers on the side with the variable with reverse operations. Whatever you do to one side of the equals sign, you must do to the other.

EX.

a+5=14-9+2

First solve the right side of the equation.

14-9=5   5+2=7

a+5=7

Now isolate the variable by subtracting 5 from both sides.

a+5-5=a   7-5=2

a=2

So the variable (a) is equivalent to 2.

Harrizon [31]

Answer:

Dados dos ángulos vecinos, ambos son complementarios si la suma de sus medidas es igual a 90° y suplementarios si esa suma de medidas es igual a 180°. Puesto que uno de los ángulos es el ángulo agudo mencionado en el enunciado, es decir, un ángulo cuya medida es mayor que 0° y menor que 90°. Entonces, el ángulo complementario debe ser inevitablemente menor que el ángulo suplementario.

Step-by-step explanation:

diamong [38]

Answer:

0.070

Step-by-step explanation:

Y = number on trial

Y has a negative binomial distribution

r = 3

P = 30% = 0.3 probability of positive indication.

P(Y = 11) probability of 11 employees that must be tested to get 3 positives

Y-1Cr-1*p^r*q^(y-r)

Y-1 = 11-1 = 10

r-1 = 3 -1 = 2

10C2 x 0.3³x0.7⁸

45x0.027x0.05764801

= 0.070

This is the probability that 11 employees must be tested to get 3 positives.
