Answer:

24 ways.

Step-by-step explanation:

In this case, you just need a factorial.

For the first seat, you have 4 students you can place.

For the second seat, you have 3 students.

For the third, you have 2.

For the fourth, you have 1.

So, you can arrange the students by doing 4 * 3 * 2 * 1 = 12 * 2 = 24 ways.

Hope this helps!

Answer:

<u>25%</u> is the percent error.

Step-by-step explanation:

Given:

The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

Now, to find the percent error.

As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

<em>The actual measure</em> = 2 million.

The estimated measure = 2.5 million.

<em>So, the error</em> = $2.5-2=0.5\ million.$

Now, to get the percent error:

$\frac{0.5}{2} \times 100.$

$=0.25\times 100$

$=25\%.$

Therefore, 25% is the percent error.

Len [333]

Answer: the commission that she earns for selling each suit is $13

the commission that she earns for selling each pair of shoes is $8

Step-by-step explanation:

Let x represent the commission that she earns for selling each suit.

Let y represent the commission that she earns for selling each pair of shoes.

One week, she earned $47 in commission for selling 3 suits and a pair of shoes. It means that

3x + y = 47 - - - - - - - - - - 1

The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes. It means that

7x + 2y = 107 - - - - -- - - - -2

Multiplying equation 1 by 2 and equation 2 by 1, it becomes

6x + 2y = 94

7x + 2y = 107

-x = -13

x = 13

Substituting x = -13 ,into equation 1, it becomes

3×13 + y = 47

39 +y = 47

y = 47 - 39 =

y = 8

The coordinates of the mid-point between points B and C is given by:

(-5, -10).

<h3>What is the mid-point concept?</h3>

The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.

The points in this problem are given as follows:

B(-40, -30), C(30, 10)

Hence the coordinates of the mid-point are:

x = (-40 + 30)/2 = -5.

y = (-30 + 10)/2 = -10.
