In a box there are 6 orange balls, 4 green balls and blue "x" balls. If the probability of drawing one blue ball is 1/3, what is the probability of drawing two blue bags?
Answers
Answer:
well you could write this as
1) 0.5/3
2) 1/6
so yeah.
if its 1/3 to get one blue ball, for two you would divide the numerator in half so you'd get 0.5/3

Find the required fraction.[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Let's take the fraction as x/y , where x = numerator & y = denominator.
Given,
1st condition :-
[tex] \rightarrow \frac{x + 1}{y - 1} = 1 \: \: \: \: \: \: \: \: \: - - (1) \\ [/tex]
2nd condition :-
[tex] \rightarrow \frac{x}{y + 1} = \frac{1}{2}\: \: \: \: \: \: \: \: \: - - (2) \\ [/tex]
__________________
Now, let's take eq. (2) & find the value of x using cross multiplication.
[tex] \frac{x}{y + 1} = \frac{1}{2} \\ 2x = 1(y + 1) \\ 2x = y + 1 \\ x = \frac{y + 1}{2} [/tex]
We got x as y+1/2. Now, let's substitute this value of x in eq. (1) & solve it using cross multiplication.
[tex] \frac{x + 1}{y - 1} = 1 \\ \frac{ \frac{y + 1}{2} + 1 }{y - 1} = 1 \\ \frac{ \frac{y + 1}{2} + 1}{y - 1} = \frac{1}{1} \\ \frac{y + 1}{2} + 1 = y - 1 \\ \frac{y + 3}{2} = y - 1 \\ y + 3 = 2(y - 1) \\ y + 3 = 2y - 2 \\ y - 2y = - 2 - 3 \\ - y = - 5 \\ \boxed{ y = 5}[/tex]
The value of y is 5. Now, let's find x. (x = y+1/2)
[tex]x = \frac{y + 1}{2} \\ x = \frac{5 + 1}{2} \\ x = \frac{6}{2} \\ \boxed{x = 3}[/tex]
So, the values of x & y respectively are 3 & 5. Now, the required fraction will come in the form of x/y. So, the fraction is...
[tex] \frac{x}{y} \\ = \large\boxed{\boxed{ \bf\frac{3}{5} }}[/tex]
The correct answer is 3/5 (option b).__________________

3.4662 times 10^2
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
You move right 1 unit and left 7 units. You end at (-5, -1). Where did you start?

Answer:
you started at (-5, 4)
Step-by-step explanation:
do what the instructions given said but in reverse. so move up 7 units and move back down 1 unit and you will find where you started.
Florida Company (FC) and Minnesota Company (MC) are both service companies. Their stock returns for the past three years were as follows: FC: −5 percent, 15 percent, 20 percent; MC: 8 percent, 8 percent, 20 percent. Calculate the mean return for each company.
Answers
Using the mean concept, it is found that:
The mean return for Florida Company is 10%.The mean return for Minnesota Company is 12%.The mean of a data-set is given by the sum of all observations divided by the number of observations.
For Florida Company(FC):
3 returns, of -5%, 15% and 20%.Thus, the mean is:
[tex]M = \frac{-5 + 15 + 20}{3} = \frac{30}{3} = 10[/tex]
The mean return for Florida Company is 10%.
For Minnesota Company(MC):
3 returns, of 8%, 8% and 20%.Thus, the mean is:
[tex]M = \frac{8 + 8 + 20}{3} = \frac{36}{3} = 12[/tex]
The mean return for Minnesota Company is 12%.

a seed spouted and grew 2/3 of a foot in 3 months. what was its rate of growth
Answers
Answer:
0.2222 of growth in a month
Step-by-step explanation:
2/3feet / 3 months
Answer:
The rate of growth of sprout seed in 3 months is 1.14%
Step-by-step explanation:
Given as:
The length of seed sprout grew = foot
The time period for sprout grew = 3 month
Let The rate of sprout grew = r%
Let The initial length of seed = l foot
So, The length of seed sprout grew after 3 months = × l foot
Now, According to question
The length of seed sprout grew after n months =
Or , × l =
Or, =
Or, 1 + =
Or, = 1.14
∴ r = 1.14 ×100 = 114
So, The rate of growth = r = 1.14 %
Hence The rate of growth of sprout seed in 3 months is 1.14%

\alpha = 1 - 95% = 1 - 0.95 = 0.05
\alpha / 2 = 0.05 / 2 = 0.025

~Let first define the domain of f(x).

☼︎~On differentiating both sidesw. r. t. x, we get

~So, using these results, we get
[tex]\sf {\:\longmapsto f'(x) = \dfrac{1}{x + 1} - \dfrac{(x + 2)\dfrac{d}{dx}2x - 2x\dfrac{d}{dx}(x + 2)}{ {(x + 2)}^{2} }}[/tex]

[tex]\rm \: f'(x) = \dfrac{ {(x + 2)}^{2} - 4(x + 1)}{(x + 1) {(x + 2)}^{2} }[/tex]
[tex]\rm \: f'(x) = \dfrac{ {x}^{2} + 4 + 4x - 4x - 4}{(x + 1) {(x + 2)}^{2} }[/tex]
