Answer:

x=y

Step-by-step explanation:

Collect Like terms from 2x+3y=5y

Like this: 2x=5y-3y (when switching sides, turn positive into negative, negative into positive)

2x=5y-3y

Simplify

2x=2y

Simplify

x=y

An urn contains 4 red balls, 5 green balls and 3 yellow balls. An experiment consists of picking 4 balls simultaneously. What is

Gemiola [76]

Using the hypergeometric distribution, it is found that there is a 0.1515 = 15.15% probability that you pick at least 3 green balls.

The balls are chosen without replacement, hence the <em>hypergeometric </em>distribution is used.

<h3>What is the hypergeometric distribution formula?</h3>

The formula is:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

In this problem:

There are 4 + 5 + 3 = 12 balls, hence N = 12.

5 of the balls are green, hence k = 5.

4 balls will be picked, hence n = 4.

The probability that you pick at least 3 green balls is:

$P(X \geq 3) = P(X = 3) + P(X = 4)$

Hence:

$P(X = 3) = h(3,12,4,5) = \frac{C_{5,3}C_{7,1}}{C_{12,4}} = 0.1414$

$P(X = 4) = h(4,12,4,5) = \frac{C_{5,4}C_{7,0}}{C_{12,4}} = 0.0101$

Then:

$P(X \geq 3) = P(X = 3) + P(X = 4) = 0.1414 + 0.0101 = 0.1515$

0.1515 = 15.15% probability that you pick at least 3 green balls.

What is the truth value for the following conditional statement? p: true q: false ∼q → ∼p T F → F T T → F F T → T T F → T

arsen [322]

Answer:

False F

Step-by-step explanation:

You are given two statements p and q. For these two statements fill in the logic table:

$\begin{array}{ccccccccc}p&|&q&|&\sim p&|&\sim q&|&\sim q\rightarrow \sim p\\T&|&T&|&F&|&F&|&T\\T&|&F&|&F&|&T&|&F\\F&|&T&|&T&|&F&|&T\\F&|&F&|&T&|&T&|&T\end{array}$

So, when p is true and q is false, statement $\sim q\rightarrow \sim p$ is false.

Write 7x^2 -4 + 6x^3 -4x -x^4 in standard form

Nata [24]

-x⁴+ 6x³- 7x²- 4x - 4

Order from least to greatest exponent (the variable, which is x in this case, is always first by the way in terms of order, then integers). This point of this problem is essentially to just rearrange the original equation.
