There's no dividing the angle in half in the trig triangle area formula.

Area = (1/2) ab sin C = (1/2) ac sin B = (1/2) bc sin A

Answer: check second and third choices

Wewaii [24]

Answer: 0.0667117 * $10^{6}$ miles

Step-by-step explanation: The Earth is one astronomical unit from the sun i.e.1AU= 93 million miles.The angular speed of the Earth traveling around the sun is approximately 0.9863 degrees per day. If we assume the orbit of the Earth is completely circular, what is the linear speed in miles per hour?

Step-by-step explanation: First, a day has 24 hours. Knowing how far the earth travels in day we can say:

0,9863 degrees/day = 0,9863 degrees/(24 hours)

0,9863 degrees/day = 0.0411 degrees/hours

Also, we know the orbit completely circular, so the total distance on, degrees, is 360°. Also this distance can be know with the formula:

Total Circuference = 360° = 2*pi* R

Because Radius is variable for any circle. It is say that:

360° = 2*pi radians

WIth this relation, we can know how many radians are 0.0411 degrees

360/0.0411 = (2*pi)/x

x = (2*pi*0.0411)/(360)

X = 0.00071733032

X is how much the Earth travels per hour in Radians.

Multiplying per Radius:

Earth distance traveled per hour = 0.0667117 * $10^{6}$ miles

Robinâ€™s scores: 99, 108, 102, 107, 119 Mean = 107; MAD = 5. 2 Evelynâ€™s scores: 125, 137, 138, 145, 145 Mean = 138; MAD = 5.

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean.

The MAD implies that Evelyn scores are more spread out than Robin scores.

The given parameters:

Robin scores = 99, 108, 102, 107 119
Mean of Robin score, = 107
Mean absolute deviation = 5.2
Evelyn scores = 125, 137, 138, 145
Mean of Evelyn score = 5.6

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean. It implies the absolute distance from the mean of the data set.

The absolute distance of Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Thus, we can conclude that Evelyn scores are more spread out than Robin scores.
