Answer:
Explanation:
To calculate, the binomial distribution formula can be applied
P(X)= nCx * Px * (1 - P)^(n - x)
Random sample of 6 adults:
P(X≥3) = P(X=3) + P(X=4) + P(X=5) + P(X=6)
(6 C 3)0.30^3 * 0.7(6-3) + (6 C 4)0.30^4* 0.7^(6-4) +(6 C 5)0.30^5* 0.7^(6-5) + (6 C 6)0.30^6* 0.7^(6-6) =
0.1852+0.0595+0.0102+0.0007
= 0.2556
[6 C 3 = 6!/(6-3)!3! = 1*2*3*4*5*6/1*2*3*1*2*3, and to calculate others apply to this formula]
Before it stopped being sold on the market in 1978, lead paint was widely-used. Paint chips from older houses built in the 1960's would most likely contain lead. Lead's cognitive effects are well-documented.
Children exposed to lead are more likely to have a lower ability when it comes to learning. For Joey, who is 2 years old, prevent this increase of acquiring neurological damage by dealing with the paint chip in the house. For best results, contact a professional lead abatement team.
Answer:
$8,925
Explanation:
Calculation of simple Interest is by the formula
I= P x r x t
Where I = Interest
p= principal
r= interest rate
t= time in years
In this case
I=$4016.25
p=???
r= 9% or 0.09
t=5 year
Therefore;
$4016.25= P x 0.09 x 5
$4016.25 = P0.45
P=$4016.25/0.45
P=$8,925
The principal is $8,925
Answer:
