What is the measure of X ?

viktelen [127]

Answer:

Step-by-step explanation:

Since 88 and the angle inside the triangle right next to it are a linear pair, their measure must add up to 180 degrees. Therefore, that angle's measure must be 180-88=92 degrees. Since all of the interior angles of a triangle must add up to 180 degrees as well, 50+92+x=180, meaning that x=180-92-50=38 degrees. Hope this helps!

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.

Solve the equation.<br><br> −t\4=−3π

vampirchik [111]

we have

$-\frac{t}{4} =-3\pi$

solve for t

Multiply by $-4$ both sides

$-\frac{t}{4}*(-4) =-3\pi*(-4)$

$t=12\pi$

therefore

<u>the answer is</u>

$t=12\pi$
