ANSWER
EXPLANATION
Lines WO and WX are tangents to the circle.
The angle subtended at the center, Z by minor arc XO is the angle subtended at the circumcenter by the same arc.
Therefore the central angle is 2x°.
The two radii ZX and ZO meets the tangents at right angles.
This implies that:
Or
Divide both sides by 2
Answer:
0.61196
Step-by-step explanation:
When we are given a random number of samples , we solve using the z score formula
z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean = 34.6
σ is the population standard deviation = 13.6
n is the random number of samples = 37
For x = 32
z = 32 - 34.6/13.6/√37
z = -1.16288
Probability value from Z-Table:
P(x = 32) = 0.12244
For x = 36
z = 36 - 34.6/13.6/√37
z = 0.62617
Probability value from Z-Table:
P(x = 36) = 0.7344
The probability their mean hours worked per week is between 32 and 36 hours per week is calculated as:
P(x = 36) - P(x = 32)
= 0.7344 - 0.12244
= 0.61196
A.) equal
B.) 10.4
