<u>Angle Measurement Units</u>
To convert from different units for angle measurements, we have to recall that:
180 degrees = π radians
If we are given the angle in degrees, multiply by π/180 to convert it to radians.
If the angle is given in radians, multiply by 180/π to convert to degrees.
We are given the angle:
Multiplying by 180/π:
Simplifying:
x = 168.75°
Answer:
51.60% probability that a randomly selected adult has an IQ between 86 and 114.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the probability that a randomly selected adult has an IQ between 86 and 114.
Pvalue of Z when X = 114 subtracted by the pvalue of Z when X = 86. So
X = 114
has a pvalue of 0.7580
X = 86
has a pvalue of 0.2420
0.7580 - 0.2420 = 0.5160
51.60% probability that a randomly selected adult has an IQ between 86 and 114.
