Answer: 34%.

By definition of normal distribution, ≈68% of the data is within 1 standard deviation of the mean. Therefore 68% of IQs are between 85 and 115, and half of that is on the lower end, 85 to 100.

Determine the measure of ∠Q, rounded to the nearest tenth of a degree.<br> images attached.

const2013 [10]

Answer:

Step-by-step explanation:

Using the Sine rule in Δ QRS , that is

$\frac{q}{sinQ}$ = $\frac{r}{sinR}$ , that is

$\frac{15}{sinQ}$ = $\frac{12}{sin50.1}$ ( cross- multiply )

12× sinQ = 15 × sin50.1° ( divide both sides by 12 )

sinQ = $\frac{15sin50.1}{12}$ , thus

Q = $sin^{-1}$ ( $\frac{15sin50.1}{12}$ ) ≈ 73.5° ( to the nearest tenth )
