I'm pretty sure it's 1/12, please don't be mad if I got it wrong
X^2/2 + ( y + 4)^2/6 = 1.
Hi there! The answer is 3, so the last option is correct.
In order to ealuate the expression for the given value of the variable(s), we must plug in the value of x into the equation.
-x2 - 4x; x = –3
We get the following

Use PEMDAS, so work out the exponents first.

Now multiply and remember that a negative times a negatives gives you a positive outcome.

Add.

Therefore, the answer is 3.

Answer: (E) H0 : µ = 10.4 vs Ha : µ < 10.4
Step-by-step explanation:
The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
The recent plant journal indicated that the mean height of mature plants of a certain species of sunflower is 10.4 ft. This is the null hypothesis.
The biologist sunflower thinks that the mean height is shorter than reported. This is the alternative hypothesis.
Therefore, the correct null and alternative hypotheses are
(E) H0 : µ = 10.4 vs Ha : µ < 10.4
