Answer:
1 Batch... i think.
Step-by-step explanation:
So, like, half of 15 is 7.5. That makes two batches. I don't think we're supposed to say 0.5=1 batch here, cause that is unrealistic.
5 is in the hundreds place
Answer:


Step-by-step explanation:
Given (Omitted from the question)



Solving (a): 
This is calculated using:


<em>We used Total - 1 because it is a probability without replacement</em>
So, we have:





Solving (b) 
This is calculated as:








Answer:
option A is correct.
Step-by-step explanation:
Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°
Since, A minor arc is an arc smaller than a semicircle. A central angle which is subtended by a minor arc has a measure less than 180°.
The minor arc is equal to the measure of the central angle.
We could also see the angle from the figure attached to the answer.
Hence we will obtain an acute angle.
Hence, option A is correct.
