Answer:

0

Step-by-step explanation:

Because anything times 0 equals 0, therefore the x^2 would be nullified and it  would be a regular binomial equation

X = y 2 - 1
pochemuha
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!

odness-of-fit test where all assumptions were met yielded the chi-square test statistic χ2=1.92 and a corresponding p-value of 0
mojhsa [17]

Answer: hello the options related to your question is missing attached below are the options

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^2+b^2=1305, a*b=648, a-b=?
luda_lava [24]

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

Which value of x makes the equation 0.5(x + 15) = 2 + 0.75(x - 4) true?
SIZIF [17.4K]

Answer:

Step-by-step explanation:

\frac{1}{2}(x+15) = 2 + \frac{3}{4}(x-4)

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

2(x+15) = 8 + 3(x-4)

now use the distributive property

2x + 30 = 8 + 3x - 12\\

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

2x - 3x = 8 - 12 - 30\\

now simplify

-x = -34\\x = 34

to test, we can plug in back to the original

\frac{1}{2}(34+15) = \frac{49}{2}\\\frac{8}{4} + \frac{3}{4}(34-4) = \frac{8}{4} + \frac{90}{4} = \frac{98}{4} = \frac{49}{2}

it works
