[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Identify

Angle θ = ∠R

Opposite Leg of ∠R = 10√3

Hypotenuse = 20

Step 2: Solve

Substitute in variables [sine]: $\displaystyle sin(R^\circ) = \frac{10\sqrt{3}}{20}$
[Equality Property] Trig inverse: $\displaystyle R^\circ = sin^{-1}(\frac{10\sqrt{3}}{20})$
Evaluate trig: $\displaystyle R = 60^\circ$

Solve the problem. For a standard normal distribution, find the percentage of data that are between 3 standard deviations below

solong [7]

Answer:

83.85%

Step-by-step explanation:

We will use the empirical rule. For a standard normal distribution the mean is equal to 0 and the standard deviation is equal to 1. Then, between 3 standard deviations below the mean, we have 2.35% + 13.5% + 34% = 49.85% of data, and 1 standard deviation above the mean we have 34% of data. Therefore, the percentage of data that are between 3 standard deviations below the mean and 1 standard deviation above the mean is 49.85%+34% = 83.85%.

Which graph represents the linear function y= -5x + 2

Semmy [17]

Look at all the options... the correct one should have a negative slope (so it would be a line decreasing), and it should also intersect on the Y axis at 2.
