proportions are just equivalent fractions
-5/-10 would be your answer =)
Answer:
A) x + 2 ≤ 3
Step-by-step explanation:
To solve for this, you subtract 2 from both sides leaving you with:
x ≤ 1
which is what the graph is showing.
Answer:
B. 13a + 7b + 4.5c
Step-by-step explanation:
trust me bruh
Answer:
the probability that at the end, at least 5 people stayed the entire time = 0.352
Step-by-step explanation:
From the question, 3 of the people are sure to stay the whole time. So, we'll deduct 3 from 6.which leaves us with 3 that are only 2/5 or 0.4 sure that they will stay the whole time.
Thus, what we need to compute to fulfill the probability that at the end, at least 5 people stayed the entire time of which we know 3 will stay, so for the remaining 3,we'll compute;
P[≥2] which is x~bin(3,0.4)
Thus;
P(≥2) = (C(3,2) x 0.4² x 0.6) + (C(3,3) x 0.4³)
P(≥2) = 0.288 + 0.064
P(≥2) = 0.352
X = -12 !!
so first rewrite the fraction
multiply both sides
move the constant to the right
change the signs
then you have your solution
