Your answer is 3.3
-Hope I helped you. :)
c = 4/5(kp + m)
Divide both sides by 4/5 or multiply by 5/4
5/4c = kp + m
Subtract m from both sides
5/4c - m = kp
Divide by k on both sides
(5/4c - m) / k = p
p = (5/4c - m) / k
You can divide the total number of outcomes.
f(a) = 3a² + 8a + 5
substitute x = a into f(x)
f(a) = 3a² + 8a + 5
Answer:
At least one student is 23: Must be true
Some students are younger than 15: Could be true
Step-by-step explanation:
Statement 1: A median is a number in the middle for ex. 1, 2, 3, 4, 5 in this example 3 is the median. Another ex could be 1, 2, 3, 4, 5, 6. This time you would have to add (3 + 4), divide by 2, which equals 3.5.
Since there are 21 students in class making it an odd number 23 must be true.
Statement 2: Based on the information I am given, I would say could be true because the difference between the oldest and the median is 29 - 23 = 6 so it could be true.
