The total number of sample space in this item is calculated by adding up all the number of students given. That is,
S = 600 + 400 + 300 + 200 = 1500
The probability is calculated with the equation below.
P = n / S
where P is the probability,
n is the number of sophomores, and
S is the total number of students
Substituting,
P = 400 / 1500 = 4/15
<em>ANSWER: 4/15</em>
Okay so 3n- 4 =?
We have to insert the -2 into the problem where n is creating,
3(-2)-4=?
Then we simplify,
-6-4=?
Lastly the answer,
-10
Answer:
my teacher gave me the exact answer for this
Step-by-step explanation:
If we simplify like terms on left and right sides we gwt
16x + 9 = 4x
Its B
Answer:
smallest triangle BCD
x = 15
Step-by-step explanation:
9/x = x/(16 + 9)
x² = 25(9)
x = ±15
