To find the mean, add all of the numbers together and divide by however many numbers there are. You may want to double check, but i got 2,080 for the first question.
To find median it it literally the number in the middle of the list, so for A, the median is 3, B’s median is 1, C is 3, and D is 2.
Range is the difference between the highest and lowest numbers, so you take the highest and subtract the lowest from it. The highest in all of these is 3, and the lowest is 1, so 3-1. The range for all of them is 2.
I hope this is helpful for you :-)
Let me know if any of this doesn’t make sense or if you need more help with it and I’ll comment:)
Answer:
It is 1800 degrees. All sides are the same length, or congruent and all interior angles are the same size
Step-by-step explanation:
Eric bought a canoe for $333.75 and the sales tax was 5.25%.
If you are trying to calculate the sales tax amount, you just convert the percentage into a decimal, and then multiply it by the price.
5.25% = 0.0525
0.0525 * 333.75 = <span>17.521875
Therefore, the sales tax amount is approximately $17.52.
If you are trying to find the total price of Eric's purchase, you would just add the sales tax to the price of the canoe.
17.52 + 333.75 = $351.27
The total cost of Eric's purchase was approximately $351.27.

⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2
