4/29 is the probability that a student who did not complete the homework passed the test.
<u>Step-by-step explanation:</u>
It is given that,
There are 29 students in a math class.
Two types of students who passed the test and are not passed the test.
The other two types of students are who completed the assignment and did not complete the assignment.
So, the given data can be formed as a table.
- There were 22 students who passed the test.
- There were 20 students who completed the assignment.
- There were 18 students who passed the test and also completed the assignment.
Passed the test Not passed the test Total
Completed assignment 18 - 20
Not completed assignment x - -
Total 22 - 29
Now, you need to find the probability that a student who did not complete the homework passed the test.
⇒ No.of students completed assignment passed the test / Total students.
<u>To find the no.of students completed assignment passed the test :</u>
Let 'x' is the no.of students completed assignment passed the test.
⇒ 18+x = 22
⇒ x = 22 - 18
⇒ x = 4
∴ P(students completed assignment passed the test) = 4 / 29.
Answer:
Hmmm What about the pair of skew lines lol
Step-by-step explanation:
Could you add more details/options !!!!
-I'd be glad to help <3 !!!!
First step find a common multiple, e.g. 45 and subtract
9x + 5y = 28 * 5
5x + 9y = 56 * 9
45x + 25y = 140
-(45x + 81y = 504)
-56y = -364
56y = 364
y = 6.5
Substitute into any equation
9x + 5(6.5) = 28
9x + 32.5 = 28
9x = -4.5
x = -0.5
x = -0.5 , y = 6.5

Step-by-step explanation:
Please see attached picture for full solution.
In order to find out whether something is a function or not, you can choose to graph the equation or find out using other methods. If the equation passes the vertical line test, such that each x value has only one corresponding y value, then the equation is a function. In other words, something is a function only if each of its inputs has only one output. You can find out whether the equation is a function through substituting values into the equation or finding the table of the graph of the equation. The simplest method available if you have a graphing calculator is to just draw a straight line above any x-value. If there's only one point on the graph that has that x-value, then the equation you're talking about is a function. If not, then it's not a function.
