How do you write this in standard form 2x+3y=12

Akimi4 [234]

To get y by itself subtract 2x from both sides. The left side becomes 3y=12-2x. Then divide by 3 on both sides to get y by itself. Which you get y=4-(2/3)x

Formalize the following argument by using the given predicates and then rewriting the argument as a numbered sequence of stateme

sergiy2304 [10]

Answer:

The answer is " $\bold{((P_2 \wedge P_3)\longrightarrow P_1 \longrightarrow P_1 }$ ".

Step-by-step explanation:

Let assuming the following predicates:

$\to B(x,y)= \text{x barks at y} \\\\\to D (x)= \text{x is a dog} \\\\\to C (x)= \text{x is a cat} \\\\$

In the given table it calculates the numbered sequence, which is given in the statement and calculates the other details, please find the attached file.

Premise P1 means whether dogs are shouting at cats.

Premise P2 means Maximum is a dog.

Premise P3 means that a cat is Moonbeam.

Unless the assumptions P1, P2, and P3 all are valid, otherwise the conclusion that Maximum starts barking at Moonbeam also is correct.

By both the law of deduction of Modus Ponens, statement 4 is the interpretation of states 1, 2, and 3. That conclusion can thus be conveyed as follows:

so, the final answer is " $\bold{((P_2 \wedge P_3)\longrightarrow P_1 \longrightarrow P_1 }$ "

g100num [7]

Answer:

a) 0.4567

b) 6 hours

Step-by-step explanation:

We are given the following information the question:

The battery life follows a normal distribution with

$\mu = 9.75\\\sigma = 2.3$

Formula:

$z = \displaystyle\frac{x-\mu}{\sigma}$

a) We have to find probability such that battery life exceeds 10 hours, that is,

P(X>10)

$P(z > \displaystyle\frac{10 - 9.75}{2.3}) = P(z>0.1086)\\\\= 1 - P(z \leq 0.1086)\\= 1- 0.5433\\=0.4567$

b) We have to find battery life such that

$P(X \leq x) = 0.05\\\\P(z \leq \displaystyle\frac{x-9.75}{2.3}) = 0.05\\\\\displaystyle\frac{x-9.75}{2.3} = -1.64 \\\\x = (-1.64)(2.3) + 9.75\\x = 5.978$
