Answer:
250 Ghana
Step-by-step explanation:
500 ÷ 8 = 62.5
62.5 = 250
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%

Solve: 4(6x - 10) = 8x + 40
A 0
B.5/2
c. 23
D. 5
<h3><u>Answer:</u></h3>
Option D
The solution to given equation is x = 5
<h3><u>Solution:</u></h3>
Given that we have to solve the given equation
4(6x - 10) = 8x + 40
Let us solve the above expression and find value of "x"
Multiplying 4 with terms inside bracket in L.H.S we get,
24x - 40 = 8x + 40
Move the variables to one side and constant terms to other side
24x - 8x = 40 + 40
Combine the like terms,
16x = 80
Thus solution to given equation is x = 5
Hello from MrBillDoesMath!
Answer:
x^3 - 6 x^2 - x + 6
Discussion:
The polynomial is
(x-1) (x - (-1)) (x-6) =
(x-1)(x+1)(x-6) = => as (x-1)(x+1) = x^2 - 1
(x^2-1)(x-6) =
x^2(x) - 6 x^2 - 1x + 6 =
x^3 - 6 x^2 - x + 6
Thank you,
MrB
