I’m saying (x+2) if you factor the denominators
If a person is not healthy, then he or she will find it very difficult to enjoy life. Balanced food, fresh air, exercise, good posture, plenty of rest, pure water, cleanliness, regular check-ups at the doctor and dentist " all helps keep our body machines running as they should.
A fit person is also more resistant to illnesses. The simplest way of keeping fit is by exercising regularly. But the exercises must be vigorous. Secondly we have to watch what we are eating. There should be enough fibre, protein, fruit, vegetables and vitamins. And of course our bodies need water. Water allows our blood to flow through the blood vessels thus supplying the body with vital nutrients. We must drink about six glasses a day.
We have to get enough sleep. All of us know how cranky we can get if we do not have enough sleep. And what's more " avoid stress, worry and tension, think positive! A bath or a shower every day is a good habit. It makes us clean but it also helps us to fall asleep better. Brushing our teeth is part of keeping clean.
Answer:
0.13093
Step-by-step explanation:
Give. That :
Population mean = 40% = 0.4
Sample size (n) = 64
Probability that more than 30 have computer at home
Mean = np = 64 * 0.4 = 25.6
Standard deviation = sqrt(n*p*(1-p)) = 3.919
P(x > 30)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (30 - 25.6) / 3.919 = 1.1227353
p(Z < 1.122) = 0.13093 ( Z probability calculator)
as a fraction of 180, m < 1 = 1/ (1 + 3 + 2) * 180 = 1/6 * 180 = 30 degrees
m < 2 = 3*30 = 90 degrees
and m < 3 = 30*2 = 60 degrees
