How do I solve 5(3m-6)

son4ous [18]

Answer: follow my steps below

Step-by-step explanation:

First, remove the variable so as to not confuse you.

You always multiply whats on the outside to what inside parentheses. 5×3 is 15 and 5×6 is 30

Next, you subtract to get the negative. -15

So for you final answer, it's -15m

Let X be the waiting time for a car to pass by on a country road, where X has an average value of 35 minutes. If the random vari

Gelneren [198K]

Answer:

Probability that the wait time is greater than 37 minutes is 0.3474.

Step-by-step explanation:

We are given that the random variable X is known to be exponentially distributed and X be the waiting time for a car to pass by on a country road, where X has an average value of 35 minutes.

<u><em>Let X = waiting time for a car to pass by on a country road</em></u>

The probability distribution function of exponential distribution is given by;

$f(x) = \lambda e^{-\lambda x} , x >0$ where, $\lambda$ = parameter of distribution.

Now, the mean of exponential distribution is = $\frac{1}{\lambda}$ which is given to us as 35 minutes that means $\lambda = \frac{1}{35}$ .

So, X ~ Exp( $\lambda = \frac{1}{35}$ )

Also, we know that Cumulative distribution function (CDF) of Exponential distribution is given as;

$F(x) = P(X \leq x) = 1 - e^{-\lambda x}$ , x > 0

Now, Probability that the wait time is greater than 37 minutes is given by = P(X > 37 min) = 1 - P(X $\leq$ 37 min)

P(X $\leq$ 37 min) = $1 - e^{-\frac{1}{35} \times 37}$ {Using CDF}

= 1 - 0.3474 = 0.6525

So, P(X > 37 min) = 1 - 0.6525 = 0.3474

Therefore, probability that the wait time is greater than 37 minutes is 0.3474.

Can anyone pls help again it was 6 questions I got wrong so pls anyone, so I might post a lot but I really need this.

Strike441 [17]

To solve this we must first add up all the values.

3.29+1.28+2.49+1.59=8.65

$8.65 is our total.

Now we find 8% of the total amount. In order to do this we must first find the decimal form of the percent. It's quite simple all we have to do is move the decimal point two spaces forward. We add a 0 in front of the decimal point after that.* (True for all one digit percents)*

8.00%+ 2 spaces forward = 0.08

Then we simply multiply the percent times the total amount.

$8.65*0.08=0.69

We add the last value to the total amount and we have our answer.

$8.65+0.69=$9.34

The total amount benjamin is going to pay is $9.34 (including tax)

Hope this helps and have a great day!

Multiply and simplify. (x + 3)(x - 8)

Kazeer [188]

Answer:

$x^{2} - 5x - 24$

Step-by-step explanation:

( x + 3 )( x - 8 ) =

$x^{2}$ - 8x + 3x - 24 = $x^{2}$ - 5x -24
