Select the correct vectors.

Paha777 [63]

In the case above, the correct vectors are:

<25.98, -15>.
<1.71, 4.7>.

<h3>What is the ship vector about?</h3>

The solution for the Ship's vector are:

Note that the Horizontal aspect = 30 cos 30

= 25.98.

For the Vertical aspect = 30 sin(-30)

= -15.

Hence it will be <25.98, -15>.

In regards to the current's vector:

The Horizontal aspect= 5 sin 20

= 1.71.

The Vertical aspect = 5 cos 20

= 4.7.

Hence it will be <1.71, 4.7>.

Therefore, In the case above, the correct vectors are:

<25.98, -15>.
<1.71, 4.7>.

Suppose on a certain test, fifty students earn a perfect score and fifty students earn a zero. determine the mean grade and stan

kodGreya [7K]

Answer:

Mean=50.

standard deviation=50.

Step-by-step explanation:

Let the perfect score be 100.

The mean(average) of a data is given by: $Mean=\frac{sum of data points}{number of data points}$

Here the number of data points are 100. out of which 50 attains a value 100,and 50 attains value 0.

so, sum of data points=50×100+50×0=5000.

$Mean=\frac{5000}{100}$

Mean=50.

"Now the standard deviation of data points are calculated by firstly subtracting mean from every entry and then square the number and take it as new entry and calculate the mean of the new data entry and lastly taking the square root of this new mean".

Here if 50 is subtracted from each entry the new entry will have 50 entries as '50' and 50 entries as '-50'.

next on squaring we will have all the 100 entries as '2500'.

now the mean of these entries is: $\frac{2500\times100}{100}$

=2500

taking it's squareroot we have $\sqrt{2500}=50$

Hence, standard deviation=50.
