Answer:
1). Mean = 2.275
2). Median = 2 vehicles
Step-by-step explanation:
From the given table,
Number of vehicles (x) Frequency (f) (f)×(x) Cumulative freq.
0 11 0 11
1 52 52 63
2 66 132 129
3 35 105 164
4 19 76 183
5 12 60 195
6 5 30 200
Number of households = 200
Mean = 
= 
= 2.275
Median = value of 
observation
= value of 
observation
= Value of 100.5th observation
= Since 100.5th observation lies in the row of cumulative freq. = 129
= 2
Therefore, median number of registered vehicles per California household
= 2 vehicles
Perimeter- 14x+6
Just add al the sides up like normal
Area- 12x^2+9x
Multiply the length and width
C)
Perimeter- 118
Area- 840
I’m pretty sure these are right
Answer:
There are two sources that serve as the foundation for conducting research on learning. The first source addresses characteristics of knowledge itself and the different ways in which we learn things. The second source focuses on what goes on in our minds and how that is theoretically represented.
Step-by-step explanation:
The investigations on the process of how we learn have led to two main sources:
- Acquisition of knowledge which involves assimilation or understanding, storage and retrieval
- The second source belongs to a modern learning cognitive psychology, neuroscience, and cognitive science theories on mental representation, which concerns about the build up of an internal symbol or cognitive representation to hypothetically figure out, external reality.
Answer: m = 2
Step-by-step explanation:
What we know:
- The slope needs to pass through the points (1, -5) and (4, 1)
- There are 4 potential slopes given to us- only one is correct
- We need to find the slope and make sure it is an option
How to solve:
By using the slope equation and the two points given to us, we can calculate the slope.
Process:
- Set up equation (y2 - y1) / (x2 - x1)
- Substitute (1 +5 ) / (4 - 1)
- Simplify 6 / 3
- Simplest form 2/ 1 =
Slope = 2
Solution: m = 2
