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:
Let fertilizer be F
and peat moss be P
since F is proportional to P
F = kP
where, k = constant of proportionality
k = F/P
putting in the values,
k = (3/4) /12
k = 3/4 * 1/12
k = 1/16
Therefore the constant of proportionality is 1/16.
A. y ≤ −2x + 3
y ≤ x + 3
B. y ≥ −2x + 3
y ≥ x + 3
C. y ≤ −3x + 2
y ≤ −x + 2
D. y > −2x + 3
y > x + 3

8.3%
Step-by-step explanation:
answer in scientific notation
To subtract numbers in scientific notation, both terms must be expressed in the same form. Convert 9.87 x 10^7 to 98.7 x 10^6, subtract 2.5 x 10^6 to get 96.2 x 10^6, and then convert this back to 9.62 x 10^7.
To solve the given problem 9.87 x 10^7 - 2.5 x 10^6, we need to make sure that both terms are in the same form of scientific notation. Here, the base (10) and the exponent (7 and 6) are already in the form of scientific notation. The next step is to perform the subtraction.
Because the two terms are not in the same order of magnitude, we cannot subtract directly. First convert them into the same form: 9.87 x 10^7 is the same as 98.7 x 10^6. Now, we can perform the subtraction: 98.7 x 10^6 - 2.5 x 10^6 = 96.2 x 10^6.
However, the typical form of scientific notation has just one digit before the decimal point, thus convert 96.2 x 10^6 back to 9.62 x 10^7.

Answer:
Only one solution.
Step-by-step explanation:
y = 3x +2
y -2x =4
y - 2x = 4
=> y = 2x +4
y = 3x + 2
y = 2x + 4
Since both equations are not the same, so the answer cannot be "infinitely many solutions".
They both intersect each other 1 point, so it cannot be "no solutions".
So the answer is "Only 1 solution".
