20% is 0.2, so it is greater.
Answer:
150 seeds sprouted
Step-by-step explanation:
First divide 270/9, you will get your rate for 1/9th
Then multiply by 5
a=6, b=2
Step-by-step explanation:
Use simplification into substitution
We can now plug this value of <em>a</em> into the second equation.
Get rid of fractions in the numerators and/or denominators
Then we can match the denominators
Combine
Divide both sides by three
Get rid of fractions
Single out <em>b</em>
Now we can plug it into the equation
Now we can check it;
↑CORRECT
↑CORRECT
B=1/2
9/16=1/2b(3/4)
Divide both sides by 3/4
1/4=1\2b
Multiply both sides by 2
Answer: r = -0.64
Step-by-step explanation:
The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r. Values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship .
Values between -0.3 and -0.7 indicate a moderate negative linear relationship .
The only value of r in the option is r= -0.64 lies in given interval of moderate negative linear relationship .
Therefore, c is the right answer.
