Answer: Perimeter=24 ft
Explanation: 2+5+7+2+5+3=24
1) Find the missing part, 7-2=5
2) Find the other missing part, 5-2=3
Answer:
The displacement is <u>2500 m</u> towards west.
Step-by-step explanation:
Taking west as negative direction and east as positive direction.
Velocity of man jogging west = -2.5 m/s
Time he traveled towards west = 1,200 s
Displacement in west direction = 
Velocity of man jogging east = 1.0 m/s
Time he traveled towards east = 500 s
Displacement in west direction = 
Total displacement can be calculated by finding the sum of displacement.
Total displacement = 
Since, the resultant displacement is negative, so the displacement is 2500 m towards west.
The sales price is 44. 37 dollars.
Answer:
a) 0.1108
(b) 0.0173
Step-by-step explanation:
We are given that 20% of all stock investors are retired people. A random sample of 25 stock investors is taken.
Firstly, the binomial probability is given by;
where, n = number of trails(samples) taken = 25
r = number of successes
p = probability of success and success in our question is % of
retired people i.e. 20%.
Let X = Number of people retired
(a) Probability that exactly seven are retired people = P(X = 7)
P(X = 7) =
= = 0.1108
(b) Probability that 10 or more are retired people = P(X >= 10)
P(X >= 10) = 1 - P(X <= 9)
Now, using binomial probability table, we find that P(X <= 9) is 0.98266 at n = 25, p = 0.2 and x= 9
So, P(X >= 10) = 1 - 0.98266 = 0.0173.
Answer:
x = 4
Step-by-step explanation:
180° - 114° = 66°
15x - 6 = 66
15(4) - 6 = 66
60 - 6 = 54
Statement is wrong because we can see another angle. so...
Final answers: x = 4 while 54 + 114° = 168° then 180° - 168° = 12°
