Lets get stated :)

2x ( -1 ) - 4 = - 2
- 2x - 4 = - 2

Bring 4 to the right-hand side { You do addition to the opposite }
- 2x = - 2 + 4
- 2x = 2

Take - 2 to the other side in order to isolate x { Do division when you see multiplication }
$\frac{-2x}{-2} = \frac{2}{-2}$
x = -1

Quick check:
2 ( - 1 ) ( - 1 ) - 4 = - 2
2 - 4 = - 2
- 2 = - 2
So it is the correct value

If A denotes some event, what does Upper A overbar denote? If P(A)equals0.999, what is the value of P(Upper A overbar)? Wh

meriva

Answer:

<h3>The event $P(\overline{A})$ denotes the complement of event A.</h3><h3>The value of $P(\overline{A})$ is 0.001</h3>

Step-by-step explanation:

Given that A denotes some event .

And also given that P(A)=0.999

<h3>To find the value of $P(\overline{A})$ :</h3>

Here the event $P(\overline{A})$ denotes the complement of event A Therefore $P(\overline{A})$ contains all the events that does not occur in A.

We know that the total probability is 1

So we have that

$P(A)+P(\overline{A})=1$

$P(\overline{A})=1 -P(A)$

$=1-0.999$

$=0.001$

Hence the complement of event A is $P(\overline{A})=0.001$

<h3>Therefore the value is $P(\overline{A})=0.001$ </h3>

Steve,Jerry and Ron were paid $29.25 to remove garden gnomes. They each worked 4 hours, exempt for Ron, who was 1 hour late. How

Ron should receive $7.98. Jerry and Steve each worked for 4 hours, while Ron was one hour late, so he worked for 3 hours. Together, they worked for 4*2+3=11 hours, receiving $29.25 in total. Each hour should be paid 29.25/11=2.66 dollars. Ron worked for three hours, so he should receive 3*2.66=7.98 dollars.

The amount of lines of symmetry of a shape is equal to the number of sides that shape has.

A heptagon has 7 sides, so, there are 7 lines of symmetry.

Best of Luck!
