The RMS speed of a molecule in Mars's atmosphere is; 345.11 m/s
How to calculate the RMS Speed?
The root mean square (RMS) speed of a gas molecule is simply defined as the classical average speed that a molecule possesses within a collection. The RMS speed of a gas is calculated using the equation:
υ = √(3RT/M)
Where;
R is the gas constant = 8.315 J/mol
T is the temperature (in Kelvin)
M is the molar mass of the gas
Temperature in degree kelvin = -63 + 273.15 = 210.15 K
Molar mass of carbon dioxide is: 44.01 g/mol = 0.04401 kg/mol
Thus;
υ = √(3 * 8.315 * 210.15/0.04401)
υ = 345.11 m/s

square pqrs has sides of length $4$, and $m$ is the midpoint of $\overline{rs}$. a circle centered at $m$ with radius $2$ intersects the circle centered at $p$ with radius $4$ at points $n$ and $s$. what is the distance from $n$ to $\overline{ps}$?
The distance between N and PS is 3.2.
What is the midpoint of the segment?
Take the distance between the two endpoints and divide it by two. This distance from either end is the line's midpoint. Alternatively, add the endpoints' x coordinates and divide by 2. Repeat for the y coordinates.
From the below figure,
N is the intersection of the red and blue circles.
I’ve drawn PQRS as the square (0,0), (4,0), (4,4), and (0,4).
Then the formula for the red circle is:
(x-2)² + (y-4)² = 4.
The formula for the blue circle is
x² + y²- 16 = 0.
Solving for x and y yields intersections
(0, 4) and (3.2, 2.4),
the first being S and the latter being N.
Hence, the distance between N and PS is 3.2.

A set of elementary school student heights are normally distributed with a mean of 105105105 centimeters and a standard deviation of 101010 centimeters. Ikue is an elementary school student with a height of 90. 490. 490, point, 4 centimeters. What proportion of student heights are lower than ikue's height?.
0.0721 proportion of the students in the class have a height less than Ikue's height.
Here, we are given that a set of elementary school student heights are normally distributed with a mean of 105 cm ⇒ μ = 105 and standard deviation 10 cm ⇒ σ = 10
The z score can be calculated using the formula-
Z = (X - μ) / σ
X is the observed value, here, X = 90.4
Since we need the proportion of student heights are lower than ikue's height, we look at the negative z score only.
Substituting the values in the z score formula we get-
Z = ( 90.4 - 105) / 10
Z = - 1.46
Now, from the z score tables, we see that the value of Z < -1.46 is 0.0721.
Thus, 0.0721 proportion of the students in the class have a height less than Ikue's height.

If an 80% confidence interval for a proportion is found to be (0.27, 0.33), then the sample proportion would be 0.30
What do you understand by sample proportion?Sampling is frequently used to estimate the proportion of a population that has a given attribute, such as the proportion of all faulty goods coming off an assembly line or the proportion of all individuals visiting a retail store who make a purchase before leaving. The percentages for the population and sample are written as p and p, respectively. Thus, if 43% of individuals visiting a business make a purchase before departing, p = 0.43; if 78 people enter the store and make a transaction, p=78/200=0.39.
The sample proportion is a random variable because it differs from sample to sample in ways that are impossible to anticipate in advance.
How to solve?
For this case the confidence interval is given by:
(0.27; 0.33)

The area of the triangle in the image is 1/20 square centimeters.
How to find the area of the figure in the image?This is a rather trivial problem.
On the image, we can see a triangle where the height and the base are known quantities.
Remember that for a triangle of height H and base B, the area is given by the formula:
A = B*H/2
Here we can see that:
H = (1/6) cm
B = (3/5) cm
Then we can replace these two fractions on the area formula, we will get:
A = (1/6 cm)*(3/5 cm)/2
A = (3/5*6 cm²)/2
A = (3/30*2 cm²)
A = (3/60 cm²) = (1/20 cm²)
