Answer:
Θ = 18.2°
Step-by-step explanation:
Using the law of sines in the triangle
= ( cross- multiply )
8 × sinΘ = 5sin30° ( divide both sides by 8 )
sinΘ = = 0.3125
Θ = (0.3125) ≈ 18.2° ( nearest tenth )
Take the third equation and divide it by 2. If the equations are the same, they have infinitely many solutions because every point on one eq. is the same on the other. You can say they overlap.
Check the picture below.
they're at a 3:1 ratio, thus, 3 times.
There is a formula for this:
Total Time = (worker1 * worker2) / (worker1 + worker2)
(3 * 8) / (3 + 8)
24 / 11 =
2.1818181818 hours
The closeness of the scores to the mean value is reflected through the values of the standard deviation. The smaller the value of standard deviation, the closer are the individual values to the mean. Therefore, since Mrs. Rijo's class has the smallest value for the standard deviation, her class has the closest individual score to the mean. The answer is the fourth choice.
