Answer:

200

Step-by-step explanation:

1. 4 times 5 because there are 5 types in total and they make 4 of each type in each batch they bake. 4*5 is 20.

2. 20 times 10 because they make 10 batches and you know there are 20 in each batch. so 20 times 10 is 200.

In a certain town, 22% of voters favor a given ballot measure. for groups of 21 voters, find the variance for the number who fav
Galina-37 [17]
<span>c. 4.6
       
21 X .22= 4.6
       
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
