Answer:
5x+2y =-6 ........1
3x-2y = 22 ........2
Add both Equations
we get
8x = 16
Divide both sides by 8
x = 2
Substitute x = 2 into any of the equations
3(2) - 2y = 22
-2y = 22 - 6
- 2y = 18
Divide both sides by -2
y = - 9
x = 2 y = - 9
Hope this helps
Answer:
C
Step-by-step explanation:
Answer:
The answer is a). 5/24.
Step-by-step explanation:
For the seventh graders there are 4 Boys + 2 Girls which totals 6 students.
- The probability that a girl will be picked from the <em>seventh graders is 2/6</em>
For the eighth graders, there are 3 Boys + 5 Girls which totals 8 students
- The probability that a girl will be picked from the <em>eighth graders is 5/8</em>
To find the<u> probability that both are girls</u>, we multiply the two fractions together:
The probability that number of credit cards is 0 is 0.61
<h3>What is Probability ?</h3>
Probability is the likeliness of an event to happen ,
It has a range from 0 to 1 , where 0 indicates uncertainty while 1 indicates certainty
The data for the college students is given and it has been asked to determine P(0)
The total students are 200
and the students that have no credit card from the data is 122
Therefore
P(0) = 122/200 = 0.61
Therefore the probability that number of credit cards is 0 is 0.61
