They are both an average calculation to the nearest whole number.
First find the area of the whole pizza.
The formula for area of a circle is Area = PI x r^2
The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.
I will use 3.14 for PI since the problem doesn't say what value to use.
Area = PI x 65.5^2
Area = 3.14 x 4290.25
Area = 13,471.39 square feet
Divide the total area by the number of pieces:
13,471.39 / 50 = 269.43 square feet
To find the length of the crust first find the circumference of the whole pizza:
Circumference = PI x diameter
Circumference = 3.14 x 131 = 411.34 feet
Now divide the total by the number of pieces:
411.34 / 50 = 8.23 feet
Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.
The correct order to determine if the results are significant are as follows:
1. Randomly separate the employee's individual results into two groups.
2.Calculate the mean of each group.
3. Calculate the difference of the means
4. Run the experiment many times
5. Calculate the probability of a difference of 5.
These steps are used to determine statistical significance by finding difference of means.
The arc length in degrees is 53 degrees
to find the legth find the fraction of the circle the arc is, this would be 53/360
multiply that by the circumference to find the length:
53/360 * 18 = (53*18) / 360 = 954 / 360 = 2.65 inches
Answer:
53.7
Step-by-step explanation:
So first move the decimal in 2.3 by one to the left, making it 23. Now what you do to one thing you do to the other, now 123.51 becomes 1235.1. Now you have 1235.1 / 23. 23 goes into 1235; 53 times, leaving you with 16.1. Now we take 16.1 / 23. When you do that you get .7. Therefore your answer is 53.7
Hopefully this helped!
