Answer:

x= 85 is the answer. ( because exterior angle of a triangle is equal to 2 non adjacent interior angle of a triangle..)

Answer:

0.052 > 0.05, which means that there is not significant evidence that the population mean is less than a.

Step-by-step explanation:

At the null hypothesis, we test if:

$H_0: \mu \geq a$

At the alternative hypothesis, we test if:

$H_1: \mu < a$

Standard significance level of 0.05:

If the p-value > 0.05: no significant evidence that the population mean is less than a.

p-value < 0.05: significant evidence that the population mean is less than a.

You obtain a P-value of 0.052. Which of the following statements is true?

0.052 > 0.05, which means that there is not significant evidence that the population mean is less than a.

The distance from the sun is option 2 5.59 astronomical units.

Step-by-step explanation:

Step 1; To solve the question we need two variables. P which represents the number of years a planet takes to complete a revolution around the Sun. This is given as 13.2 years in the question so P = 13.2 years. The other variable is the distance between the planet and the sun in astronomical units. We need to determine the value of this using the given equation.

Step 2; So we have to calculate the value of 'a' in Kepler's equation. But the exponential power $\frac{3}{2}$ is on the variable we need to find so we multiply both the sides by an exponential power of $\frac{2}{3}$ to be able to calculate 'a'.

P = $a^{\frac{3}{2} }$ , $P^{\frac{2}{3} }$ = $a^{\frac{3}{2}*\frac{2}{3} }$ , $P^{\frac{2}{3} }$ = a, $13.2^{\frac{2}{3} }$ = a = 5.58533 astronomical units.
