Answer:
Option C) 0.2358
Step-by-step explanation:
We are given the following data set:
0.23105, 0.4725, 0.8765, 0.4865, 0.5326, 0.7976
Formula:
where are data points, is the mean and n is the number of observations.
Sum of squares of differences = 0.1122752556 + 0.008765640625 + 0.09633264063 + 0.006340140625 + 0.001123925625 + 0.05358067562 = 0.2784182787
Thus, the standard deviation for given data is
Option C) 0.2358
The equation that relates x and y is y = (1/3)x if the variables x and y vary directly and x = 18, y = 6.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
The question is incomplete.
The complete question is:
The variables x and y vary directly. Use the given values to write an equation that relates x and y. x = 18 y = 6
From the question:
y ∝ x
y = kx ..(1)
k is the constant of proportionality after removing the proportional sign.
Plug x = 18 and y = 6
6 = 18k
k = 1/3
Plug the value of k in the equation (1)
y = (1/3)x
Thus, the equation that relates x and y is y = (1/3)x if the variables x and y vary directly and x = 18, y = 6.

Opposite side length = 9
Adjacent side length = 12
Hypotenuse side length = 15
sin∅ is found with (opposite/hypotenuse). Therefore, sin∅ = 9/15.
cos∅ is found with (adjacent/hypotenuse). Therefore, cos∅ = 12/15.
tan∅ is found with (opposite/adjacent). Therefore, tan∅ = 9/12.
The answer is D.
