blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
The answer and working are shown in the photo below
Answer:
The true solution is x=4/9
EXPLANATION
The logarithmic equation given to us is
We need to use the quotient rule of logarithms.
When we apply this law the expression becomes
We now take the antilogarithm of both sides to get
We square both sides to get,
We evaluate to obtain,
This simplifies to
We divide both sides by 36 to get
We simplify to get,
It is necessary to include the term one then you will have the plus three
<span>Ans : According to the Equation -
10.2638 + 0.0491x
= 10.2638 + 0.0491 X 748 ( Because x= 748, given )
= 10.2638 + 36.72
= 46.99
= 47 (Approximately)</span>
