The number of six samples that could belong to the same population is equivalent to six.
Option A is the correct answer.
What is the standard deviation?The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.
The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.
Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.

Lesson 6 homework practice select an appropriate display answer key
Answer:
I want to know what the answer is
Explanation:
14- The points (-3,0), (1,0), and (2,0)
all lie in the xy-plane on the graph of
the polynomial function f. Which of
the following could define f?
(A) f(x) = (x + 1)(x + 2)(x − 3)
(B) f(x) = (x + 1)(x − 2)(x+3)
(C) f(x)=(x-1)(x + 2)(x+3)
(D) f(x) = (x - 1)(x − 2)(x+3)
Answer:
d) f(x)= (x-1)(x-2)(x+3)A balloon takes 1 minute to rise 60 feet in the air. each minute after that, the balloon rises 40% as far as it did the previous minute. which equation represents the total distance, d, in feet that the balloon rises in 6 minutes?
The equation represents the total distance, d, in feet that the balloon rises in 6 minutes [tex]d=\frac{60(1-0.4^6)}{1-0.4}[/tex].
Given that a balloon takes 1 min to rise 60 feet in the air each min after that it rises 40% as far as the previous minute
So it second minute it rises 40% x 60 feet (60 x 0.4)= 24 feet in 3rd minute it rises 40% x 24 feet = (24x0.4) = (60x0.42) feet
So in n-th minute it rises (60 x [tex]0.4^{n-1}[/tex]) feet
So total height d in n- minutes will be
d = 60 + (60 × 0.4) + (60 × 0.4²) + ... + (60 x 0.4"-1)
= 60[1 + 0.4 + 0.4² + ... + 0.4" 1]
[tex]=60 \times \frac{1-0.4^n}{1-0.4}[/tex]
here n=6
So it will rise to
[tex]d=\frac{60(1-0.4^6)}{1-0.4}[/tex]
