Ms. White has 15 students in her first grade class. Troy is the line leader for the week, and Mackenzie is last because she was the line leader last week. In how many different ways can Ms. Whites class line up for lunch?A.) 13!
B.) 15!
C.) 15!÷2!

Answers

The first place and 15th place are already decided, so we have to find the number of different ways that the other 13 students can line up, in the places from 2 to 14.

2nd place can be any one of 13 people. For each of those . . .

3rd place can be any one of 12 people. For each of those . . .

4th place can be any one of 11 people. For each of those

13th place can be any one of 2 people. For each of those

14th place has to be the one student who is left.

Total number of ways that 13 students can line up in places 2 through 14 is

(13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)

That number is called "thirteen factorial". The number is 6,227,020,800 .

Nell's mortgage is $50,150 at 10 percent for 30 years. What is her monthly payment if she must pay 8.78 points per $1,000? (Points : 1) $440.32
$439
$422.95
$385.89

Answers

I actually don't know the actual computation. I used a mortgage points calculator and inputted the data given.

The monthly payment given based on its computation was $440.10. The closest answer is 440.32.

The difference in decimal point is due to the rounding off of 8.78 points to 8.8 points in the calculator.

Find the slope of the line that passes through the points (-8,-3) and (2, 3)0
1
3/5
5/3

Answers

Answer:

The answer is

$(3)/(5)$

Step-by-step explanation:

To find the slope passing through two points we use the formula

$m = (y2 - y1)/(x2 - x1)$

Where

m is the slope

( x1 , y1) and ( x2 , y2) are the points

From the question the points are

(-8,-3) and (2, 3)

So the slope is

$m = (3 + 3)/(2 + 8) = (6)/(10) = (3)/(5)$

When a volcano erupts, the height of the peak is reduced and the upper portion is removed. The height of a volcano after it erupted was 8,219.5 feet. This was 85% of the original height. What was the original height?

Answers

The height of the volcano is reduced after the eruption, then the original height of thevolcano is 9670 feet.

What is the Percentage?

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information in the question,

Height of the volcano after eruption = 8,219.5 feet

Let the original height of the volcano is x.

85% of x = 8219.5

x = (8219.5 × 100)/85

x = 9670 feet.
