Bx – 10 = f solve for x(z/2) - b = hSolve for z

Mathematics
1 answer:
Free_Kalibri [48]1 year ago
4 0

1) To solve for x, is to let x on the left side and the other terms and variables on the right side.

bx -10=f <em>Add 10 to both sides</em>

bx = f+10 Divide by b on both sides

So that's the way we solve for x.

b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.

z = 2h +2b

Which set of ordered pairs does not represent a function?
Irina18 [472]
<h3>Answer:</h3>

B. { (3, –2), (3, –4), (4, –1), (4, –3) }

<h3>Step-by-step explanation:</h3>

Functions are a set of points that show how dependent variables change through independent variables.

Defining a Function

In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.

For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.

Graph of a Function

Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.

What is the probability that a randomly selected graduate has a job if he or she is attending college? Give your answer as
Andrej [43]

Complete question :

Suppose that of the 300 seniors who graduated from Schwarzchild High School last spring, some have jobs, some are attending college, and some are doing both. The following Venn diagram shows the number of graduates in each category. What is the probability that a randomly selected graduate has a job if he or she is attending college? Give your answer as a decimal precise to two decimal places.

What is the probability that a randomly selected graduate attends college if he or she has a job? Give your answer as a decimal precise to two decimal places.

Answer:

0.56 ; 0.60

Step-by-step explanation:

From The attached Venn diagram :

C = attend college ; J = has a job

P(C) = (35+45)/300 = 80/300 = 8/30

P(J) = (30+45)/300 = 75/300 = 0.25

P(C n J) = 45 /300 = 0.15

1.)

P(J | C) = P(C n J) / P(C)

P(J | C) = 0.15 / (8/30)

P(J | C) = 0.5625 = 0.56

2.)

P(C | J) = P(C n J) / P(J)

P(C | J) = 0.15 / (0.25)

P(C | J) = 0.6 = 0.60

En Colima se lleva acabo la conferencia sobre la energética eólica a la cual asistieron 120 representantes de Latinoamérica y Su
andriy [413]
The first thing we must do for this case is to see how many representatives from each country attended.
 We have then:
 Argentines = (1/6) * (120) = 20
 Chileans = (1/5) * (120) = 24
 Bolivians = (1/4) * (120) = 30
 Venezuelans = (1/4) * (120) = 30
 Adding we have:
 20 + 24 + 30 + 30 = 104
 Therefore the number of Americans is:
 120-104 = 16
 Answer:
 16 Americans attended the wind energy conference
