Answer:
The probability the event that none of them are obese is 0.0352.
Step-by-step explanation:
<h3>Binomial distribution:</h3>
A discrete random variable X having to the set {0,1,2,3....,n} as the spectrum, is said to have binomial distribution with parameters n= the number of trial, and p= probability of successes on an individual trial , if the p.m.f of X is given by,
for x=0,1,2,...,n
=0 elsewhere.
where 0<p<1 and n an positive integer,
Given that,
The probability of the event that a child living in an urban area in the united state is obese is 20%.
n=Number of children = 15, p= 20%= 0.20.
The probability the event that none of them are obese is
=P(X=0)

=0.0352
Answer:
72.22 inches
Step-by-step explanation:
Okay so the formula for circumference is C=2πr so since the diameter is twice the radius, the radius is 11.5. Now you have to multiply 11.5 and 2. That equals 23. Now you have to multiply 23 by π which is about 3.14. 23 times 3.14 is 72.22 inches.
Hope this helped!! :D
Maria is wrong because they have completed 1/2.
Step-by-step explanation:
At the top of the Ferris wheel,the ride is 1/2 done. All that is left is to go down,which is the other half. Maria is wrong in saying they are 1/4 done,that is a quarter,not half.
Hi
Fractions that have a common denominator of 8, would be fractions that have denominators that, when multiplied, equal 8.
8/2 = 4
8/3 = 2.7
So the first option is incorrect.
8/4 = 2
8/2 = 4
The second option is correct.
The correct answer is 1/4 and 1/2
Hope this helps! :)
There are 98 terms.
98*(33+130)/2 = 7987
