The equation 4s = 33.4 models a constant rate situation. Drag and drop the value of 2s in the box. a 16.7

yKpoI14uk [10]

The answer to the equation you posted The equation 4s = 33.4 models a constant rate situation. what is <span>the value of 2s is:
to make the given equation 4s = 33.4 to 2s, divide the whole equation by 2

1/2 ( 4s = 33.4)
4s/2 = 33.4/2
2s = 16.7

i hope that i answered your question. feel free to ask further questions</span>

Which equation is equivalent to –k + 0.03 + 1.01k = –2.45 – 1.81k?

ElenaW [278]

K(-1+1.01)+0.03=-2.45-1.81k
0.01k+1.81k=-0.03-2.45
1.82k=-2.42
k=-2.45\1.82=1.3

Apparently the practice of smoking reduces the ability to fall asleep, demanding much more time in individuals who smoke, than in those who do not smoke.

Step-by-step explanation:

a, b) For the group of smoking individuals, the average time it takes to fall asleep and the standard deviation of those times is:

$\bar X_F={\frac{1}{n} \sum_{i=1}^n x_i = 43.7$

$S_F=\sqrt{\frac{1}{n-1} \sum_{i=1}^n (x_i-\bar{x})^2}=16.9278$

a, b) For the group of non-smoking individuals, the average time it takes to fall asleep and the standard deviation of those times is:

$\bar X_{NF}={\frac{1}{n} \sum_{i=1}^n x_i = 30.32$

$S_{NF}=\sqrt{\frac{1}{n-1} \sum_{i=1}^n (x_i-\bar{x})^2}=7.12783$

c. In the attached file you can see the diagram of points for the times, in the smoking and non-smoking groups.

d. Apparently the practice of smoking reduces the ability to fall asleep, demanding much more time in individuals who smoke, than in those who do not smoke.

The average heights of four samples taken from a population of students are shown in the table. Which of these is most likely cl

Ne4ueva [31]

Answer:

It would be D, 62

Step-by-step explanation:

The sample size for the group with the average height is the highest, being at 40 instead of 30, 20, or 10, and therefore has the most accurate average height.
