Answer:
Dean Renata thinks that the professor has underestimated the number of students with part-time or full-time jobs, is statistically evident.
Step-by-step explanation:
Here we are testing whether proportion of the students at Flora College who work while attending school is 35% or more than 35%
(Right tailed test at 5% level of significance)
Sample proportion p = 
Assuming H0 to be true, std error of proportion = 
p difference = 0.1305
Z = test statistic = 2.40
p value for one tailed = 0.0082
Since p < 0.05 we reject H0
Dean Renata thinks that the professor has underestimated the number of students with part-time or full-time jobs, is statistically evident.

Step-by-step explanation:
The sum of two numbers is 44 and their difference is 14. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 44. In other words, x plus y equals 44 and can be written as equation A:
x + y = 44
The difference between x and y is 14. In other words, x minus y equals 14 and can be written as equation B:
x - y = 14
Now solve equation B for x to get the revised equation B:
x - y = 14
x = 14 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 44
14 + y + y = 44
14 + 2y = 44
2y = 30
y = 15
Now we know y is 15. Which means that we can substitute y for 15 in equation A and solve for x:
x + y = 44
x + 15 = 44
X = 29
Summary: The sum of two numbers is 44 and their difference is 14. What are the two numbers? Answer: 29 and 15 as proven here:
Sum: 29 + 15 = 44
Difference: 29 - 15 = 14
Answer:
x = - 4
Step-by-step explanation:
x = 19 is a vertical line parallel to the y- axis
A line parallel to it has the equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 4, 7 ) with x- coordinate - 4 , then
x = - 4 ← equation of parallel line
