The planet Neptune orbits the Sun. Its orbital radius is 30.130.1 astronomical units (\text{AU})(AU).

Ronch [10]

Answer: 189.028 AU.

Step-by-step explanation:

Given: The radius of the orbit = 30.1 AU

Since, the orbit is circular in shape, then the distance traveled by Neptune is given by:-

$\text{Circumference=}2\pi r\\\\\Rightarrow\ \text{Circumference=}2(3.14)\times(30.1)\\\\\Rightarrow\ \text{Circumference=}=189.028\text{ AU}$

Hence, the distance traveled by Neptune in a single orbit around the Sun = 189.028 AU.

Exhibit 5-8 The student body of a large university consists of 60% female students. A random sample of 8 students is selected. R

expeople1 [14]

Answer:

P(X=2)=0.04129

Step-by-step explanation:

-This is a binomial probability problem whose function is expressed as;

$P(X=x)={n\choose x}p^x(1-p){n-x}$

-Given that p=0.6, n=8 , the probability that among the students in the sample exactly two are female is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=2)={8\choose2}0.6^2(1-0.6)^6\\\\=0.04129$

Hence, the probability of exactly two females is 0.04129

Solve for x and justify your answer

Scorpion4ik [409]

The answer is 51°.

The top two lines are parallel to each other. Therefore alternate interior angles theorem applies. The bottom right corner that is underneath the line (for lack of a better description) is also 58°.

We also know that a triangle equals 180°. So 58+71= 129°.

So to find that missing angle we subtract 129 from 180 to get the 51°.

A triangle has side lengths of (x-6), (x+2) and (x-9). Find the perimeter of the triangle

Setler [38]

Answer:

3x - 13

Step-by-step explanation:

The perimeter is just the distance around the triangle. We have all three sides, so we can just add them together to get the total distance.

(x-6) + (x+2) + (x-9)

Group:

x + x + x - 6 + 2 - 9

3x - 13
