A coach divided his team into two groups of equal size.

Mathematics
1 answer:
DerKrebs [107]3 years ago
4 0

Applying the percentages, and considering that 70% of the first group drinks at least 2 glasses of water a day, it is found that 0.725 = 72.5% of the team drinks at least 2 glasses of water a day.

The team is divided into two equal groups, hence, each represents 50%.

The <em>percentages </em>associated with drinking at least 2 glasses of water a day is:

  • 70% of 50%(first group)
  • 75% of 50%(second group)

Hence, applying the weighed percentage, the total percentage is:

T = 0.7(0.5) + 0.75(0.5) = 0.725

0.725 = 72.5% of the team drinks at least 2 glasses of water a day.

A paper clip is dropped from the top of a 144‐ft tower, with an initial velocity of 16 ft/sec. Its position function is s(t) = −
hoa [83]
To calculate the velocity, we use the given expression above which is <span>s(t) = −16t^2 + 144. First, we calculate the time it takes to reach the ground. Then, differentiate the expression and substitute time to the differentiated expression.

</span>s(t) = −16t^2 + 144
0 = -16t^2 + 144
t = 3

s'(t) = v = -32t
v = -32(3)
v = -96 

Note: negative sign signifies that the object is going down

bezimeni [28]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of pens
 y: number of pencils
 We now write the system of inequations:
 x + y  \leq  25&#10;&#10;y  \geq  (x - 3) ^ 2&#10;
 The solution to the system of inequations is given by the shaded region.
