PLEASE HELP QUICK!!! 3x − 2(6 − x) = 7x + 2(5 + x) − 6

Answers

Answer:

it would be x=-4

hope i helped ya

Answer:

x = -4

Step-by-step explanation:

3x -2(6-x) = 7x +2(5+x) -6

Distribute -2 through the parentheses 3x -12 +2x = 7x +2(5+x) -6

Distribute 2 through the parentheses 3x -12 +2x = 7x +10 +2x -6

3x -12 +2x = 7x +10 +2x -6 cancel equal terms on both sides of the equation

3x -12 = 7x +10 -6 subtract the numbers 3x -12 = 7x +4

                           Move variable to the left left handed side and change its sign

3x -7x-12 = 4   -->   3x -7x = 4 + 12  -->  -4x = 4+12  --> -4x = 16

             Divide both sides of the equation by -4  -->  x = -4

Suppose that the number of miles that an EV battery (electric vehicle) can run before its battery wears out is exponentially distributed with the average value of 100,000 miles. If a car manufacturer decides to install this type of battery to power the vehicle, do the following: 1) What percentage of the cars will fail at the end of 50,000 miles

Answers

Answer:

The value is [tex]P(X = 50,000) = 6.07*10^{-6}[/tex]

Step-by-step explanation:

From the question we are told that

The average value is [tex]E(x) = 100000 \ miles[/tex]

Generally the exponential distribution function is mathematically represented as

[tex]f(x) = \{ \left \theta* e^{-\theta * x } \ ; \ \ \theta >0} \atop {0 \ ; \ otherwise }} \right.[/tex]

Here [tex]\theta [/tex] is a constant which is mathematically represented as

[tex]\theta = \frac{1}{E(x)}[/tex]

=> [tex]\theta = \frac{1}{100000}[/tex]

=> [tex]\theta =1 *10^{-5}[/tex]

So at x = 50,000 miles (given)

[tex]f(50000) = 1 *10^{-5} * e^{-1*10^{-5} * 50000}[/tex]

[tex]f(50000) = 6.07*10^{-6}[/tex]

So the percentage of the cars will fail at the end of 50,000 miles is

[tex]P(X = 50,000) = 6.07*10^{-6}[/tex]

Ammount amy earns if she sells 33 books: 88 dollars

Step-by-step explanation:

they let us know that she earns 55 dollars a week. this is the minimum she can earn in a week. So 55 is just 55. she cant earn more or less than 55 a week by just working there. the variable is the ammount of books she sells every week. Every book she sells gives her an extra one dollar to her overall wage per week. so 55 is the base and the one dollar per book is the variable that changes depending on how much she sold. So the equation would the base of 55 and the variable 1x (x being the ammount of books being sold and the 1 being how much money she makes from each book) and now just put them together with a plus sign and it would look like this

55 + 1x = ...

If she was to sell 33 books and shes earning 1 dollar per book 1(33), we only change the x from x to 33

55 + 1(33) which gives us 88

Required

Which represents the strongest correlation.

When [tex]r-value > 0.7[/tex], it is considered to be strong.

Compare this condition with the given options, we're left with:

[tex]r-value = 0.73[/tex]

[tex]r-value = 0.99[/tex]

The above r-values show strong correlation.

It is estimated that 50% of emails are spam emails. Some software has beenapplied to filter these spam emails before they reach your inbox. A certain brandof software claims that it can detect 99% of spam emails, and the probabilityfor a false positive (a non-spam email detected as spam) is 5%.Now if an email is detected as spam, then what is the probability that it isin fact a non-spam email?

Answers

Answer:

P(Non-Spam/Spam Detected) = 5/99

Step-by-step explanation:

To determine the probability that it is in fact a non-spam email, we will employ the use of Bayes Theorem: P(A/B) = (P(B/A) x P(A)) / P(B).

P(Spam) = P(Non-Spam) = 0.5  

P(Spam Detected) = P(Spam) * rate of detection = 0.5 * 0.99

P(Detected/Non-Spam) = P(false positives) = 0.05

Using Bayes Theorem, P(Non-Spam/Spam Detected) = ( P(Spam Detected/Non-Spam) x P(Non-Spam) ) / P(Spam Detected)

= 0.05*0.5 / 0.5*0.99

= 5/99

Using conditional probability, it is found that there is a 0.0481 = 4.81% probability that it is in fact a non-spam email.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.

In this problem:

Event A: Email detected as spam.Event B: It is a non-spam email.

The percentages of emails detected as spam are:

99% of 50%(spam emails).5% of 50%(non-spam emails).

Hence:

[tex]P(A) = 0.5(0.99) + 0.5(0.05) = 0.52[/tex]

The probability of an email being detected as spam and not being spam is:

[tex]P(A \cap B) = 0.5(0.05)[/tex]

Hence, the conditional probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.5(0.05)}{0.52} = 0.0481[/tex]

0.0481 = 4.81% probability that it is in fact a non-spam email.
