Answer:
the seven question is not clear
The test statistic z will be equal to -0.946 and it shows that there is no significant difference in the proportion of rehires between full time and part time.
Given sample sizes of 833 and 386 and result of samples 434 and 189.
Proportion of full time=434/833=0.52
Proportion of part time=189/386=0.49.
Difference in proportion =0.52-0.49
TTF- i∈ rho=0
TTF+i∈ rho≠0.
Mean of difference=0.03
Z=(X-μ)/σ
σ=
=0.0317
σ=0.0317
z=(0-0.03)/0.0317
=-0.03/0.0317
=-0.317
p value will be =0.1736.
Because p value is greater than 0.01 so we will accept the null hypothesis which shows that there is no significant difference in the proportions.
Hence there is no significant difference in the proportion of rehires between full time and part time.

3² = x + 5. The equivalent equation to log₃(x+5) = 2 is 3² = x + 5.
In order to solve this problem we have to know about Logarithm.
Logarithm is defined as the exponent of a power with a certain base, that is, the number to which a given base must be raised to obtain a given result.
logₐ b = x ----------> aˣ = b
Solving for log₃(x+5) = 2 where a = 3, x = 2, and b = x + 5
3² = x + 5
Answer:
Problematic x is x = 1
Step-by-step explanation:
Equation:
xy= 2x + y + 1
xy - y = 2x + 1
y(x-1) = 2x + 1
y = (2x+1)/(x-1)
The problematic x is such that when the denominator of the function is 0
x - 1 = 0
x = 1 (the problematic x)
So the domain of f is: x is the subset of R (real number) with the exception of x =/ 1 (x not equal to 1)
To prove this, we can plot the graph and in the graph we can see that as the value of x approaches from negative values to 1, y value will approaches negative infinity, and as the value of x approaches from large positive numbers, y value approaches infinity.
In other words, we'll see an assymptote at x=1
To prove that it is a function, we can do vertical line test by drawing vertical lines accross the graph. We'll see that each line crosses the equation line once hence proving the equation as a function
