Answer:
22s - 9
Step-by-step explanation:
The perimeter (P) is the sum of the 4 sides , that is
P = 2s + 7 + 9s - 5 + 6s - 10 + 5s - 1 ( collect like terms )
= (2s + 9s + 6s + 5s) + (7 - 5 - 10 - 1)
= 22s + (- 9)
= 22s - 9
Answer:
675
Step-by-step explanation:
750 gets turned into 7.50, or 7.5. Then you multiply 7.5 by 90 to get your answer
Answer:
5
Step-by-step explanation:
The midpoint of segment AB is (1, 1).
Substituting these coordinates into the equation of the line,
Answer:
48° ,132
Step-by-step explanation:
x+(x-84)=180
2x=264
x=132
132-84=48
Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.
To answer the question, we need to know what probability is
<h3>What is probability?</h3>
This is the likelihood for an event to occur. It is given by
P(event) = number of required outcomes/total number of outcomes
Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.
<h3>Probability that all of Erica's flights will be on time</h3>
So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)
= [P(flight)]⁴
= (90%)⁴
= (0.9)⁴
= 0.656
≅ 0.66
= 66%
So, the probability that all of Erica's flights will be on time is B 66%.
