Hello!
First of all, for our first scenario, the variation or spread of a data set is represented by the range. You subtract the largest and smallest number in the data set to find how much is in between.
Next, the mode is the number of piece of data that shows up the most in the data set, or the most common piece. Therefore, the most popular color is the mode.
As you can see, number 3 clearly says mean in the problem. This is the average cost.
The median is the middle number. Basically, it splits the data in half. If half of the students are 15 or higher, the middle age is 15, therefore, the median is 15.
Therefore, our answers are below.
2. Mode
3. Mean
1. Range
4. Median
I hope this helps!
Answer:

-2+7=5
Step-by-step explanation:
Answer:
f) 
e) 
d) 
c) 
b) 
a) 
Step-by-step explanation:
- m∠5 ≅ m∠4; Angle Correspondence Theorem
- m∠5 ≅ m∠1; Alternate Interior Angles Theorem
- m∠6 ≅ m∠2; Alternate Exterior Angles Theorem
- 180° = m∠2 + m∠1; Definition of Linear Pair [Supplementary Angles]
- 180° = m∠5 + m∠3; Definition of Linear Pair [Supplementary Angles]

Multiply 245 by .40 (which is 40%)
245 x (.40)= 98. When you get 98, you have to 245-98 and you get 147

Answer: 48</h3>
=====================================================
Explanation:
Triangle ABC is isosceles because AC = BC.
The angles opposite these congruent sides are angle ABC and angle BAC. These are the base angles.
For any isosceles triangle, the base angles are congruent.
Angle BAC = 69 degrees is given. So angle ABC = 69 as well.
-------------------
The missing angle must add to the two other angles so that all three angles in a triangle add to 180
(angle ABC) + (angle BAC) + (angle BCA) = 180
69 + 69 + (angle BCA) = 180
138 + (angle BCA) = 180
angle BCA = 180-138
angle BCA = 42
-------------------
Angle DCE is congruent to angle BCA because they are vertical angles.
Triangle DCE is a right triangle. The missing angle is 90-(angle BCA) = 90-42 = 48
angle EDC = 48 degrees
