Answer:

Option C)

Step-by-step explanation:

The samples are dependant.  There should be a relation between the weights of the students, even though there could be changes, as any value can go up or down. A student with a weight around of 30 has a higher chance of getting a weight around of 35 after the firts year than a student with weight around of 55. This means that the probability a student has for getting certain amount of weight after the first year may change depending on the weight the student had at the start of the year. You can therefore naturally relate the weight a student had before the first year with the weight the student had after the first year.

So, the samples are dependant because there is a natural pairing between the to samples, as option C says.

Find the measures of the angle formed by the hands of a clock at 6:45
solniwko [45]

Answer:

67.5 degrees

Step-by-step explanation:

The angle between the 6 and the 9 = 90 degrees.

WE  can say that the hour hand is ' 3/4 of 5 minutes' past the 6.

5 minutes is equivalent to  360 / 12 = 30 degrees.

Thus the angle between the 6 and the hour hand

= 30 * 3/4

= 22.5 degrees.

The required angle is  90 - 22.5

= 67.5 degrees.

Marcus, Shaun, and Tristan each invested into new business. They invested 1 point
Schach [20]

Shaun invested $176,250 into the new business.

Marcus invested half of the $940,000 so the amount that Shaun and Tristan invested is:

= 940,000 / 2

= $470,000

Shaun and Tristan invested in the ratio 3:5.

The amount that Shaun invested is:

<em>= (Ratio of Shaun / Sum of the ratios) x Amount both invested </em>

= (3 / (3 + 5 )) x 470,000

= 3/8 x 470,000

= $176,250

In conclusion, Shaun must have invested $176,250 into the business.
