Answer:
The number of classrooms needed to accommodate all the classes is 22.
Step-by-step explanation:
[text}N_{classes} / N_{time slots} = N_{classrooms}[/text]
281 / 13 = 21.6; the number of classrooms needed to accommodate all the classes is 22.
To calculate the number of classrooms that you need to accommodate 281 different classes in 13 time slots, you have to divide the number of classes (281) by the number of time slots (13). The result is 21.6 classrooms needed. However, because you cannot have a class to a 0.6 classroom, you have to round up to 22.
Answer:
First we need to find the mean and standard deviation of the given data.
The mean and standard deviation are given below:
We have:
Therefore, the percentage of values that lies within one standard deviation of the mean is:
The expected percentage of values within one standard deviation of the mean according to normal distribution is 68%.
Therefore, the observed percentage of values within one standard deviation of the mean is much higher than the expected percentage of a normal distribution.
The formula for finding the sum of the interior angles<span> of a </span>polygon<span> is the same, whether the </span>polygon<span> is regular or irregular. So you would use the </span>formula<span> (n-2) x 180, where n is the number of sides in the</span>polygon<span>. If you draw a diagonal in the square, that forms two triangles.</span>

Step-by-step explanation:
<em>An adult ticket costs $205 and a child ticket costs $49.</em>
<h2>
Explanation:</h2>
Hello! Recall you have to write complete questions in order to find exact answers. Here I'll assume the complete question as:
<em>Two families are planning a trip to Disney. The Smith family bought tickets for 2 adults and 3 children for $557. The Jones family bought tickets for 2 adults and 1 child </em><em>for $459</em><em>. How much does and adult and child ticket cost?</em>
To solve this problem, we need to write a system of linear equations in two variables. So, we know some facts:
- Two families are planning a trip to Disney.
- The Smith family bought tickets for 2 adults and 3 children for $557.
- The Jones family bought tickets for 2 adults and 1 child for $459.
Let:
For the Smith family:
Cost for the 2 adults:
Cost for the 3 children:
Total cost:
For the Jones family:
Cost for the 2 adults:
Cost for the 1 child:
Total cost:
So we have the following system of linear equations:
Subtracting (2) from (1):
Finally, <em>an adult ticket costs $205 and a child ticket costs $49.</em>
