Answer:
6,7,8
Step-by-step explanation:
All of the others are Pythagorean triples
Question 1Consider this: j starts at 5 (when k=0) and 7 is added every time k increases by 1. If k increases by 2, j will increase by
14.
Question 2If 1/6 is really 0.16, then if we use inverse operations and multiply 0.16 by 6, it should equal 1, right? However, 0.16 times 6 is only 0.96!
4/5 is not equal to 0.08 because 0.08 times 5 is only 0.4,
1/3 is not equal to 0.3 because 0.3 times 3 is only 0.9.
1/4 <em>
is</em>
equal to 0.25, because 0.25 times 4 is 1.
Question 3
What percent of 250 is 75?
Well, a percent is basically just a fraction out of 100.
Take a look at these equivalent fractions.
Answer: <u>0.4032</u>

solution:-
given that p = 0.30 , n = 17
p(x > 5) = 1 - p(x ≤ 5)
= 1 - (p(x = 5) + p(x = 4)+ p(x = 3)+ + p(x = 2)+ p(x = 1)+ p(x = 0))
= 1 - (0.2081+0.1868+0.1245+0.0581+0.0169+0.0023)
= 1 - 0.5968
= 0.4032
Answer:
1100 and 130 (km/h)
Step-by-step explanation:
1. if the velocity of the wind is 'w' and the velocity of the plane in still air is 'p', then
2. it is possible to make up two equations:
the fly against the wind: (p-w)*8=7760;
the fly with the wind: (p+w)*3=3690.
3. if to solve the system made up, then:
4. the required rate of the plane in still air is p=1100 km/h; the rate of the wind is w=130 km/h.
