Answer:

Option D) s = 1

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 69

X = 68

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Computing z-scores for different standard deviation:

z_1 = \displaystyle\frac{68-60}{4} = 2\\\\z_2 = \displaystyle\frac{68-60}{3} = 2.667\\\\z_3= \displaystyle\frac{68-60}{2} = 4\\\\z_4 = \displaystyle\frac{68-60}{1} = 8

The standard deviation with highest z-score gives the most extreme position in the distribution.

Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.

Option D) s = 1

IgorLugansk [536]
According to the question, 
Let,
"n" represent the number of miles semir walked.
"y" represent the number of miles sarah walked.
Now, according to the question,

y = 2n - 5  ........................this is your equation 
Also,
the question states, each of them collect $18 in pledges for every miles walked.

Given,
Sarah collected $450
Now, 

Using unitary method,

Sarah collects $18 for 1 mile
Sarah collects $1 for (1 / $18) mile
Sarah collects $450 for (1 / 18) * 450 mile
                                   = 25 miles
So, Sarah walks 25 miles.
Now,
Taking equation,
y = 2n - 5
Since, y is the no. of miles sarah walked, we can write 25 in place of "y" So,
(25) = 2n - 5
25 + 5 = 2n
30 = 2n
30 / 2 = n
15 = n

Since, "n" is the no. of miles that semir walked, Semir walked 15 miles.

A long distance runner does a first lap around a track in exactly 50 seconds.As she tires.Each subsequent lap takes 20% longer t
madreJ [45]

Answer:

182 seconds

Step-by-step explanation:

Given:

Time taken for first lap is 50 seconds and each subsequent lap takes 20% longer than previous

Solution:

Time taken for first lap = 50 sec

For second lap

Each subsequent lap takes 20% longer than previous

Previous lap time = 50 sec

second lap = 50 + 20% of 50

second lap =50+(\frac{20}{100}\times 50)

second lap = 50 + 10

second lap = 60\ sec

For third lap

Each subsequent lap takes 20% longer than previous

Previous lap time = 60 sec

Third lap = 60 + 20% of 60

Third\ lap = 60 + (\frac{20}{100}\times 60)

Third\ lap = 60+2\times 6

Third\ lap = 60+12

Third\ lap = 72\ sec

Time taken for 3 laps is equal to sum of all three laps time.

Tiem\ taken\ for\ 3\ lap = 50+60+72

Tiem\ taken\ for\ 3\ lap = 182\ sec

Therefore, it takes 182 seconds (3 min, 2 seconds) to run three laps
