Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!

answer : The researcher did not state that the p-value is conditional on the null hypothesis being true ( A )
Step-by-step explanation:
What is wrong with the researcher's interpretation is that the researcher did not state that the p-value is conditional on the null hypothesis being true.
The P-value is a required value when either rejecting or accepting the null hypothesis. and the researcher did not add the clause that the probability of getting a statistic > 1.92 provided the null hypothesis is assumed to be true
a - b is 9
Step-by-step explanation:
- Step 1: Given a² + b² = 1305, a × b = 648. Find a - b using the identity for (a - b)²
⇒ (a - b)² = a² + b² - 2ab
⇒ (a - b)² = 1305 - 2 × 648 = 1305 - 1296 = 9
⇒ (a - b) = 9
Answer:
Step-by-step explanation:

To make this easier, to get ride of the fractions, we can multiply both sides by 4

now use the distributive property

now we want to isolate x to one side and isolate all the constants to the other

now simplify

to test, we can plug in back to the original

it works
