Kevin claims he can draw a trapezoid with three right angles. Is this possible? Explain.
MakcuM [25]
Using an indirect proof:

Assume that the figure is a trapezoid.
All trapezoids are quadrilaterals.
All quadrilaterals' interior angles add up to 360° because any n-gon's interior angles add up to 180(n-2)°.
We are given that the trapezoid has three right angles.
All right angles are 90°, thus these right angles have a total measure of 270°.
We can conclude fourth angle must be 90°.
If it has four right angles, it is a rectangle.
Rectangles have two sets of parallel sides.
However, trapezoids have exactly one set of parallel sides.
Alas, our figure cannot be a trapezoid.

A company decides to investigate the amount of sick leave taken by its employees. A sample of seven employees yields the followi
Svet_ta [14]

Using statistical concepts, we have that:

  • a. The range is 6 days, and the interpretation is: B. The number of days separating the fewest and most sick days taken is equal to the range.
  • b. The standard deviation is of 2.2, which means that the average spread about the mean is of 2.2 units.

<h3>Range and standard deviation:</h3>
  • The range of a data-set is given by the difference <u>between the highest value and the lowest value in the data-set</u>.
  • The standard deviation of a data-set is given by the <u>square root of the  sum of the difference squared of each observation and the mean, divided by the number of observations</u>.

Item a:

  • The lowest value is of 0.
  • The highest value is of 6.

Hence:

The range is 6 days, and the interpretation is: B. The number of days separating the fewest and most sick days taken is equal to the range.

Item b:

The mean is:

M = \frac{0 + 1 + 4 + 0 + 0 + 6 + 3}{7} = 2

Hence, the standard deviation is:

S = \sqrt{\frac{(0-2)^2+(1-2)^2+(4-2)^2+(0-2)^2+(0-2)^2+(6-2)^2+(3-2)^2}{7}} = 2.2

The standard deviation is of 2.2, which means that the average spread about the mean is of 2.2 units.

Scarlett is throwing a end of the year party for 2013
galben [10]

Answer:

7.5 pounds.

Step-by-step explanation:

the answer is 7.5 ponds because if each slider has 2 oz. then we can find the total number of oz. needed by multiplying by 60. This gets 120 oz that Scarlett needs in total. Since there are 16oz in a pound we divide 120 by 16 to find the number of pounds needed.
