Answer:
Nope.
Step-by-step explanation:
area square: s^2 if one side is 2 cm: are ais 4 cm
rhombus square: (big diagonalxsmall diagonal)/2
what counts on the rombus is not the side, but the diagonals. The diagonals are usually longer than the side of the square, so the area of the rombus is bigger.
Answer:
what's the question ?
Step-by-step explanation:
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%.

Answer:
3.75 hours
Step-by-step explanation:
Travel time can be found using the relation ...
time = distance/speed
time = (2475 mi)/(660 mi/h) = 3.75 h
It will take 3 3/4 hours to travel that distance.
