Answer:

My answer would be B.

Step-by-step explanation:

Triangle angles have to add up to a total of 180 degrees. B. has a very close measures in angles. I am sorry if this is not the answer. But let me know.

For triangle ABC, find the measure of AB given me∠ A = 55 degrees, m∠b= 44 degrees, and b=6. . A. 45.22. B.96.68. C.88.19. .
jekas [21]
There exist a similar question where b = 68 instead of 6. First, determine the measure of the third angle, angle C,
                               m∠c = 180 - (55° + 44°) = 81°
Let x be the side AB, that which is opposite to angle C. Through the Sine Law,
                                  68 / sin 44° = x / sin 81°
From the equation, the value of x is equal to 96.68. Thus, the answer is letter B.

Answer:

The variance is: $169,367,949

Step-by-step explanation:

Given

Tuition: $40,632, $35,554, $42,192, $33,432, $69,479, and $43,598

Required

Determine the variance

First, calculate the mean

\bar x = \frac{\sum x}{n}

Where

n =6

\bar x = \frac{40,632+35,554+42,192+33,432+69,479+43,598}{6}

\bar x = \frac{264,887}{6}

\bar x = 44147.8333333

\bar x = 44148 --- approximated

The sample variance (s^2) is calculated using:

s^2 = \frac{\sum(x - \bar x)^2}{n-1}

This gives:

s^2 = \frac{(40,632-44148)^2+(35,554-44148)^2+(42,192-44148)^2+(33,432-44148)^2+(69,479-44148)^2+(43,598-44148)^2}{6-1}

s^2 = \frac{846839745}{5}

s^2 = 169367949

<em>The variance is: $169,367,949</em>
