Given:
In ΔOPQ, m∠Q=90°, m∠O=26°, and QO = 4.9 feet.
To find:
The measure of side PQ.
Solution:
In ΔOPQ,
[Angle sum property]
According to Law of Sines, we get
Using the Law of Sines, we get
Substituting the given values, we get
Approximate the value to the nearest tenth of a foot.
Therefore, the length of PQ is 2.4 ft.
Answer:
The correct option is;
A. 0.17
Step-by-step explanation:
The given information are;
The mean duration it takes a cashier to process an order, μ = 276 seconds
The standard deviation from the mean, σ = 38 seconds
The z-score of the order processing time of x = 240 seconds is given as follows;
Therefore;
The probability
P(z = -0.9474) = 0.17361
Therefore, the proportion of orders which are processed in less than 240 is approximately 0.17361 or 0.17 to two places of decimal.
