(7a+3)+(-a-5)=-16
Combine like terms:6a-2=-16
Add 2 to both sides: 6a=-14
Divide both sides by 6: a=-14/6
Simplify: a=-7/3

Write the multiplicative inverse of <br>a) -13/19​
irga5000 [103]

Answer:

-  \frac{19}{13}

Step-by-step explanation:

the \: multiplicative \: inverse \: of \:  \\  -  \frac{13}{19}  =  -  \frac{19}{13}

Product of a number and its multiplicative inverse should be equal to 1.

So,

\bigg ( -  \frac{13}{19} \bigg)  \bigg ( -  \frac{19}{13} \bigg)

= \frac{13}{19}\times  \frac{19}{13}

=1

The bounds for a discrete brownian walk is [-3, 4]. what is the probability that the escape happens at 4?
Akimi4 [234]

Using it's concept, there is a 0.125 = 12.5% probability that the escape happens at 4.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Considering that the bounds for a discrete brownian walk is [-3, 4], the possible outcomes are:

-3, -2, -1, 0, 1, 2, 3, 4.

A escape at 4 is one outcome, hence the probability is given by:

p = 1/8 = 0.125.

0.125 = 12.5% probability that the escape happens at 4.
