Can someone help me with this question
1 answer:
The probability that the selected element is a member of A n B is 2/9
<h3>How to complete the number line?</h3>The elements of the set are given as:
E = {1,2,3,4,5,6,7,8,9}
A = {1,3,4,8,9}
B = {2,4,9}
Using the above parameters, we have:
A only = {1, 3, 8}
B only = {2}
A and B = {4, 9}
None = {5,6,7}
The above dataset is the represented using the attached Venn diagram
<h3>How to determine the probability?</h3>
In (a), we have:
A and B = {4, 9}
E = {1,2,3,4,5,6,7,8,9}
The probability is then calculated as:
P(A n B) = n(A n B)/n(E)
This gives
P(A n B) = 2/9
Hence, the probability is 2/9

<em>For</em><em> </em><em>the</em><em> </em><em>attached</em><em> </em><em>image</em><em>,</em><em> </em><em>note</em><em> </em><em>that</em><em> </em><em>slope</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>thing</em><em> </em><em>as</em><em> </em><em>gradient</em><em>.</em>
1) y = 2x + 4
2) Substituting in x = 1 and y = 1,
1 = 4(1) + c
1 = 4 + c
c = -3
So, the equation is y = 4x - 3
Answer:
Graph the line using the slop and y-intercept, or two points.
Slope: 1
y-intercept: -2
x: 0, 0
y: -2, -2
