<h3>
Answer: 1</h3>
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.8 + 0.55 - 0.35
P(A or B) = 1.35 - 0.35
P(A or B) = 1
A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.
Answer:
the answer to this question is 1.08
Answer:
x^6 - 7x^5 + 69/4x^4 + -35/2x^3 + 25/4x^2
Step-by-step explanation:
x^2(x-1)^2(x-5/2)^2 is the factored form of the polynomial. Now you simplify it to convert to standard form.
Answer: show A had 8394 performances.
Show B had 6010 performances.
Step-by-step explanation:
Let x represent the number of performances of show A.
Let y represent the number of performances of show B.
As of a certain date, there had been a total of 14,404 performances of two shows on Broadway. This means that
x + y = 14404 - - - - - - - - - -1
There was 2384 more performances of Show A than Show B. It means that
x = y + 2384
Substituting x = y + 2384 into equation 1, it becomes
y + 2384 + y = 14404
2y = 14404 - 2384
2y = 12020
y = 12020/2
y = 6010
x = y + 2384 = 6010 + 2384
x = 8394
Answer:
315 kg
Step-by-step explanation:
to find the weight of the horse:
1lb = 0.45 kg (rounded the .45)
(700lb) x (0.45)= 315
to find how much medicine they need:
315/10= 31.5
the horse wieghs 315kg meaning that they would need 31.5mg of medication.
