40*5%= 2
0.07x+0.02y=2
x+y=40
7x+2y=200
2x+2y=80
5x=120
x= 24
7x+2y=200
7x+7y= 280
5y=80
y=16
A: 24gallons of 7%milk
16 gallons of 2% milk
Just add 1/2 to each width. If the width is 0 then the length is .5 and that’s where you start the graph. Width is x and length is y
9 times 5 equals 45 so yes
Answer: 0.18
Step-by-step explanation:
From the question we know that p = 0.9 and q = 0.1. From this, We can compute the heterozygotes: 2pq = 2 (0.9) (0.1) = 0.18.
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.
