Answer:
The probability of all events occurring is 1
(1/6)+p=1
p=1-1/6
p=5/6
The probability of not rolling 5 is 5/6
Or you could have just said there are five numbers other than 5 out of the six so:
5/6
Plug in the known information to find the radius
r= radius
Area= πr^2
58= (3.14)r^2
divide both sides by 3.14
18.4713375796= r^2
take the square root of both sides
4.2978294033 feet= r
CIRCUMFERENCE
C= 2πr
C= 2(3.14)(4.2978294033)
C= 26.99 feet (or rounded to 27 ft)
ANSWER: 26.99 feet (or rounded to 27 ft)
Hope this helps! :)
Answer:
0.2264
0.1795
0.2264
Step-by-step explanation:
Given that:
p = 19% = 0.19
Sample size (n) = 12
Using binomial distribution formula :
p(x = x) = nCx * p^x * (1 - p)^(n-x)
1 - p = 1 - 0.19 = 0.81
Exactly 3:
p(x = 3) = 12C3 * 0.19^3 * 0.81^9
p(x = 3) = 220 * 0.001029499103502116970939
= 0.2264
B.) Atleast 4 :
P( x ≥ 4) = p(4) + p(5) + p(6) + p(7) + p(8) + p(9) + p(10) + p(11) + p(12)
To save time, we can use a binomial probability calculator :
P( x ≥ 4) = 0.1795
C.) Less than 8:
P( x < 8) = p(7) + p(6) + p(5) + p(4) + p(3) + p(2) + p(1) + p(0)
P(x < 8) = 0.9995
Answer:
Angle2 is supplementary to Angle8.
Answer:
6 more times
Step-by-step explanation:
First remember 75, 27 away from 102.
BUT hes getting more each day... 4.5 x 6 = 27
which means he will have to visit 6 more times!
:D
