180° &lt; x &lt; 270°, what is the value of tan-1(0.577)?
Allisa [31]
Think:  "Find <span>tan-1(0.577)" means "Find the ANGLE in Quadrant III whose tangent is 0.577.  Because the angle is in QIII, both the opp side and the adj side are negative.  Here you have four answer choices.  The correct answer MUST be within the interval 180 and 270 degrees.  Only one of the given answer choices satisfies that criterion.  Which one is it?

Suppose that IQ scores have a bell-shaped distribution with a mean of
Svetllana [295]

Answer:

68 %

Step-by-step explanation:

The Empirical rule formula states that:

• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Mean of 96 and a Standard deviation of 17

Applying , the first empirical rule for 1 standard deviation from the mean, we have:

μ - σ

96 - 17

= 79

μ + σ

96 + 17

= 113

Therefore, the percentage of IQ scores that are between 79 and 113 is 68%
