Answer:
Step-by-step explanation:
Given that the number of children in a household has a binomial distribution with parameters n-8 and p-50%
As per binomial definition we have
=
a) P(x=3 or 7) = P(3)+P(7) = 0.2188+0.0313=0.2501
b) P(X≤5)=0.8555
c) P(X≥3)=0.8555
d) P(x<7) =0.9648
The radius of the given circle is 2.84 units
Step-by-step explanation:
Step 1 :
Given
The perimeter of a quarter table is 17.85
We need to find the circle's radius.
Step 2 :
The circle's perimeter is given by the formula, 2 r where r represents the circle's radius
So from this we have ,
2 r = 17.85
We can determine the radius by dividing the perimeter value by 2
= > r = 17.85 divided by 2 r
= 2.84 [ taking =
]
Step 3 :
Answer :
The radius of the given circle is 2.84 units
