Answer:
A - y= 7/5 + -7/5
B- y=-5x+4
C- I cant see the other number
D- y= -5x-3
E- y=3x+15
F- y=-5x-4
Step-by-step explanation:
I think its B,D,F
sorry If its wrong!
It’s definitely not B so don’t chose that one because it’s not right
Answer:
y = 1/2x - 3
Step-by-step explanation:
y2 - y1 / x2 - x1
0 - (-4) / 6 - (-2)
4/8
= 1/2
y = 1/2x + b
0 = 1/2(6) + b
0 = 3 + b
-3 = b

Answer:
Correct option is (B) descriptive statistical method
Step-by-step explanation:
Descriptive statistics branch in statistics deals with the representation of the data using distinct brief coefficients. These coefficients are used as either the representative of the sample or the population.
The descriptive statistics branch is divided into two sub branches:
- Measure of central tendency
- Measure of dispersion.
The three measures of central tendency are:
- Mean (or Average)
- Median
- Mode.
The measures of dispersion are:
- Variance
- Standard deviation
- Range
- Kurtosis
- Skewness
The education researcher computes the average number of hours student study at various local colleges.
The average of a data is the mean value which is the measure of central tendency.
Thus, the researcher is using descriptive statistical method to summarize the data.
