What is the distribution of the test statistic under the null hypothesis
Answer:
There is no relationship between your year in school and having a job.
Step-by-step explanation:
In this instance, the chi sq test need to be performed.
Chi sq is used to determine if there is a significant relationship between two categorical variables.
The two variables here are year in school and employment status.
The two variables are independent(no relationship exists)
This implies that there is null hypothesis
Therefore, the Null Hypothesis is
There is no relationship between your year in school and having a job.
Answer:
y" = -24 / y³
Step-by-step explanation:
6x² + y² = 4
Take the derivative of both sides with respect to x.
12x + 2y y' = 0
Again, take the derivative of both sides with respect to x.
12 + 2y y" + y' (2y') = 0
12 + 2y y" + 2(y')² = 0
Solve for y' in the first equation.
2y y' = -12x
y' = -6x/y
Substitute and solve for y":
12 + 2y y" + 2(-6x/y)² = 0
12 + 2y y" + 2(36x²/y²) = 0
12 + 2y y" + 72x²/y² = 0
6y² + y³ y" + 36x² = 0
y³ y" = -36x² − 6y²
y" = (-36x² − 6y²) / y³
Solve for y² in the original equation and substitute:
y² = 4 − 6x²
y" = (-36x² − 6(4 − 6x²)) / y³
y" = (-36x² − 24 + 36x²) / y³
y" = -24 / y³

The value of x + y from the equation is 15
The equation is given as:
Add 125 to both sides of the equation
Express 125 as 100 + 25
Rewrite the equation as:
Group the expressions
Express the expressions in both groups as perfect squares
Possible equations from the above equation is:
and
Take the square roots of both sides
and
Solve for x and y in the above equations
and
So, we have:
Hence, the value of x + y is 15

Answer:
5(5) - 3(7) = 4
Step-by-step explanation:
Jose bought 750 bags for $375.00
Each bag cost $375/750= $0.50
He intends to sells them for $0.15 more
He should charge : $0.5 +$0.15=$0.65
