I hope this helps you
f (x)=(x-10)(x-2)
x=10
x=2
First set both equations equal to y
y = -1/2x + 3
y = 3x - 4
Then set these two equal because they both equal y
-1/2x + 3 = 3x + 4
Combine like terms and solve
7 = 3.5x
x = 2
y also = 2 when you plug it back in
Therefore, (2,2)
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.
Answer:
Step-by-step explanation:
Proof: square roots of prime numbers are irrational. the square root of any prime number must be an irrational number. For example, because of this proof we can quickly determine that √3, √5, √7, or √11 are irrational numbers.
moreover, √7= 2.645751311064590
This is an irrational. number
