Hi there!
To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

We can change this to

Let's solve for each individual fraction

≈ 0.27

= 10
Now, multiply.
0.27 * 10 = 2.7
That's your answer.
Have an awesome day/night! :)

Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
D. 90 im pretty sure its this. hope this helped :)
One of the answers is equilateral because all of the sides are of equal length.
The other answer is acute because all of the angles are under 90º since they are all 60º. Hope this helps!
