The approximate area of the circle is A
Answer:
This means it is between 22000000 m and 44000000 m.
Step-by-step explanation:
From the question, the UAE Hope Pobe is between 22 000 km and 44 000 km away from Mars.
Since,
1 000 m = 1 km
Then,
22 000 km = 22 000 x 1000 m
= 22000000 m
also,
44000 km = 44000 x 1000 m
= 44000000 m
Therefore, the Probe is between 22000000 m and 44000000 m.
Answer: 0.6274
Step-by-step explanation:
Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11
Sample size : n= 4
Let x be a binomial random variable that represents the people get an injection-site reaction.
Binomial probability formula: 
The required probability : P(x=0)
Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
Answer:
tan(45°) = 1
Step-by-step explanation:
We know that sin (45°) = √2/2, and cos(45°) = √2/2.
Given that tan(x) = sen(x) / cos(x), we get:
tan(45°) = (√2/2) / (√2/2) = 1
Therefore, tan(45°) = 1
Attached you will find the important angles summary
Your distance from Seattle after two hours of driving at 62 mph, from a starting point 38 miles east of Seattle, will be (38 + [62 mph][2 hr] ) miles, or 162 miles (east).
Your friend will be (20 + [65 mph][2 hrs] ) miles, or 150 miles south of Seattle.
Comparing 162 miles and 150 miles, we see that you will be further from Seattle than your friend after 2 hours.
After how many hours will you and your friend be the same distance from Seattle? Equate 20 + [65 mph]t to 38 + [62 mph]t and solve the resulting equation for time, t:
20 + [65 mph]t = 38 + [62 mph]t
Subtract [62 mph]t from both sides of this equation, obtaining:
20 + [3 mph]t = 38. Then [3 mph]t = 18, and t = 6 hours.
You and your friend will be the same distance from Seattle (but in different directions) after 6 hours.
