Answer:

<em>2.5%</em><em> of the snakes are longer than 16.6 in</em>

Step-by-step explanation:

The Z score is,

Z=\dfrac{X-\mu}{\sigma}

here,

X = raw score = 16.6

μ = mean = 15

σ = standard deviation = 0.8

So,

Z=\dfrac{16.6-15}{0.8}=2

Z-score is the measurement of how many standard deviation away the data is from the mean. Hence, the value 16.6 is 2 standard deviations right to the mean.

Approximately 95% of the data falls within two standard deviations of the mean. (between the mean-2 times the standard deviation, and the mean+2 times the standard deviation)

So the 5% of data are left in the remaining space. As we have to find the amount of snakes which are longer than 16.6 in i.e we have to find the area to the right of 16.6.

The remaining 5% of amount is divided in two equal parts.

Therefore, \dfrac{5}{2}=2.5\% of the snakes are longer than 16.6 in

The correct answer for the question that is being presented above is this one: "3.5%" The lengths of a particular snake are approximately normally distributed with a given mean mc025-1.jpg = 15 in. and standard deviation mc025-2.jpg = 0.8 in. The percentage of the snakes that are nlonger than 16.6 in is 3.5%

kykrilka [37]

Answer:

π (3.14) seconds

Step-by-step explanation:

T = 2π√(L/32)

T = 2π√(8/32)

T = 2π√(1/4)

T = 2π(1/2)

T = π

It will take π seconds for the pendulum to complete a full cycle if the pendulum is 8 feet long

Dahasolnce [82]

<u>Answer:</u>

Both trucks are 150 miles after 1.516 hours

<u>Solution:</u>

Given, Two trucks leave a factory at the same time.  

one travels east 60 miles per hour, and the other travels west at the 39 miles per hour.  

We have to find In how many hours will they be 150 miles apart?

Let the time after which they will be 150 miles apart be t.

Now, we know that, <em>distance = speed x time. </em>

For 1st truck ⇒ distance from factory = 60 x t

For 2nd truck ⇒ distance from factory = 39 x t

Here, t is same for both trucks as time is seen from common point of view.

Now, according to the given information,  

distance of 1st truck from factory + distance of 2nd truck from factory = 150 miles.

60t + 39t = 150

99t = 150

t = 1.516 approximately.

Hence, both trucks are 150 miles after 1.516 hours.
