Answer:

coinciding

Step-by-step explanation:

If you divide the second equation by 3, you get the first equation. They describe the same line, so the lines are <em>coinciding</em>.

Harry earns an hourly rate of $15. For each additional hour over 40 hours, he earns 150% percent of his regular hourly rate. Las

Yuri [45]

Answer:

51 hours

$15 x 40 = $600

$15 x 1.50 = $22.5

$22.5 x 11 = $247.5

$600 + $247.5 = $847.5

40 + 11 = 51 hours

Find the missing probability.<br> P(A) = 0.4; P(B) = 0.7; P(A or B)<br> ; P(A and B) = 0.3

solong [7]

Given:

$P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3$

To find:

The value of $P(A\text{ or }B)$ .

Solution:

We know that,

$P(A\text{ and }B)=P(A\cap B)$

$P(A\text{ or }B)=P(A\cup B)$

It means, we have $P(A)=0.4, P(B)=0.7, P(A\cap B)=0.3$ and we need to find the value of $P(A\cup B)$ .

$P(A\cup B)=P(A)+P(B)-P(A\cap B)$

$P(A\cup B)=0.4+0.7-0.3$

$P(A\cup B)=1.1-0.3$

$P(A\cup B)=0.8$

Therefore, the value of $P(A\text{ or }B)$ is 0.8.

I can't figure this out can someone answer and list steps

Pachacha [2.7K]

It would be D. Since X=2 in the beginning, and and is 8 in the end. 2*4 is 8.
So, -5 times four would be 20, but not in this context. it would be -20.
