Answer:
41.92%
Step-by-step explanation:
In table attached standard normal distribution curve is shown.
Data
mean, µ = 4.3 minutes
standard deviation, σ = 0.5 minutes
desired point, x = 5 minutes
x-axis, Z = (x - µ)/σ
The probability that calls last between 4.3 and 5.0 minutes is equivalent to find the area below the curve between Z = 0 and Z = (5 - 4.3)/0.5 = 1.4, which is 0.4192, or 41.92%
<u>Given</u>:
Given that TUV is a right triangle with measure of ∠V=90°
The measure of ∠U = 55°, and the length of VT is 82 feet.
We need to determine the length of TU.
<u>Length of TU:</u>
The length of TU can be determined using the trigonometric ratio.
Thus, we have;
where , opp = VT and hyp = TU
Thus, we have;
Substituting the values, we have;
Simplifying, we have;
Thus, the length of TU is 100.1 feet.
