Answer:
Null hypothesis =
Alternate hypothesis =
Step-by-step explanation:
Given : In a recent semester, the proportion who earned a bachelor's degree within six years was 0.395.
The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate.
To Find : Determine the null and alternative hypotheses.
Solution:
In a recent semester, the proportion who earned a bachelor's degree within six years was<u> 0.395. </u>
Claim : the proportion of students who enroll in her institution <u>have a higher completion rate.</u>
So,null hypothesis =
Alternate hypothesis =
83x+P=83x+Q
subtract 83x from each side
P=Q
if P does not Q there are no solutions
the lines would be parallel and never intersect if Q does not equal P
Answer: 31.25 ft
Step-by-step explanation:
50 / 32 = x / 20
32x = 50(20)
x = 31.25 ft
A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
