Answer:

n = -13

Step-by-step explanation:

38 = -2n + 12

<em>Subtracting</em><em> </em><em>1</em><em>2</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

==> 38 - 12 = -2n + 12 - 12

==> 26 = -2n

<em>multiplying both sides by (-1)</em><em>:</em>

==> -26 = 2n

<em>dividing</em><em> </em><em>both</em><em> </em><em>sides by 2:</em>

==> -13 = n

stealth61 [152]

<u>The </u><u>distance</u><u> from the center of the ellipse to where the spots are located will be </u><u>2 feet.</u>

What is Distance?

  • Distance is the total movement of an object without any regard to direction.
  • We can define distance as to how much ground an object has covered despite its starting or ending point.

The distance from the center of the ellipse to where the spots are located will be -

= 5 - 3

= 2 feet.

Therefore, the distance from the center of the ellipse is 2 feet.

According to the general equation for conditional probability, if (image attached)
katrin2010 [14]

Answer: Option A

P(A|B) = \frac{40}{49}

Step-by-step explanation:

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

P(A|B) = \frac{P(A\ and\ B)}{P(B)}

Then if P(A\ and\ B) = \frac{5}{7} and P(B) = \frac{7}{8} then:

P(A|B) = \frac{\frac{5}{7}}{\frac{7}{8}}\\\\P(A|B) = \frac{40}{49}

Joel Trump is paid one and one-half times the regular hourly rate for all hours worked in excess of 40 hours per week and double
Irina18 [472]

Answer:

C. $516

Step-by-step explanation:

His regular rate is $8 per hour.

Since it's 40 hours a week, it means from Monday to Friday his regular work time is 8 hours per day.

Thus, for the regular week work, he is to be paid;

40 × 8 = $320

Now, we are told he worked 9 hours each day from Monday through Friday.

This means that;

He worked 1 hour each day.

That is 5 hours extra from Monday to Friday.

He is paid one and one-half times the regular hourly rate.

Thus, for this 5 extra hours, he will be paid 1½ × 5 × 8 = $60

He works 6 hours on Saturday, and 4 hours on Sunday.

Thus;

For Saturday, he is also paid one and one-half of regular pay. Thus, he is due for;

1½ × 8 × 6 = $72

He is paid double the regular hourly pay for Sundays.

Thus, for 4 hours on Sunday, he is paid;

2 × 8 × 4 = $64

Total he is due = $320 + $60 + $72 + $64 = $516
