Answer:

$\fbox{ \huge{ \sf{ a = - 8}}}$

Step-by-step explanation:

$\bigstar{ \sf{ \: 19 = - 3a - 5}}$

$\tt{Step \: 1 \: }$ : Swap the sides of the equation

$\longmapsto{ \sf{ - 3a - 5 = 19}}$

$\tt{Step \: 2 \: }$ : Move 5 to right hand side and change it's sign

$\longmapsto{ \sf{ - 3a = 19 + 5}}$

$\tt{Step \: 3 \: }$ : Add the numbers : 19 and 5

$\longmapsto{ \sf{ - 3a = 24}}$

$\tt{Step \: 4 \: }$ : Divide both sides by -3

$\longmapsto{ \sf{ \frac{ - 3a}{ - 3} = \frac{24}{ - 3}}}$

$\tt{Step \: 4}$ : Calculate

$\longmapsto{ \sf{a = - 8}}$

$\sf ∴ \: the \: value \: of \: a \: is \: - 8.$

KonstantinChe [14]

Answer:

0.0656

Step-by-step explanation:

For each message, we have these following probabilities:

90% probability it is spam.

10% probability it is legitimate.

Compute the probability that the first legitimate e-mail she finds is the fifth message she checks:

The first four all spam, each with a 90% probability.

The fifth legitimate, with a 10% probability.

$P = (0.9)^{4} \times 0.1 = 0.0656$

WILL GIVE BRAINLIEST, THANKS, AND 5 STARS!<br> PLEASE HELP ME!

Bogdan [553]

Answer:

-4 and 4

Step-by-step explanation:

<u>Method 1</u>

Apply Difference of Two Squares Formula: $a^2-b^2=(a+b)(a-b)$

Given $x^2-16=0$

Rewrite 16 as 4²

Therefore, $a^2=x^2$ and $b^2=4^2$

$\implies a = \sqrt{x^2}=x$

$\implies b=\sqrt{4^2} =4$

$\implies x^2-16^2=(x+4)(x-4)$

$\implies (x+4)(x-4)=0$

$\implies (x+4)=0 \implies x=-4$

$\implies (x-4)=0 \implies x=4$

<u>Method 2</u>

Given equation:

$x^2-16=0$

Add 16 to both sides:

$\implies x^2-16+16=0 + 16$

$\implies x^2=16$

Square root both sides:

$\implies \sqrt{x^2}=\sqrt{16}$

$\implies x=\pm4$

Therefore, x = -4, x = 4
