Let x represent the number of spaniels
4x + x = 30
combine like terms
5x = 30
divide each side by 5
x = 6
There are 6 spaniels.
The area is 279. You do 11×19 to get the bottom portion. That will give you 209. Then for the top subtract 11 from 18 to get that side length and then do 7×10. With that you will get 70 and then you add 209 to that. 209+70=279.
Answer:
5/10 or 1/2
Step-by-step explanation:
Answer:
For each part selected, the probability of a defective part being produced must be 0.04.
The parts must be selected independently.
Step-by-step explanation:
For each part, there are only two possible outcomes. Either they are defective, or they are not. Each part has a 4% probability of being defective, and the probability of a part being defective is independent of other parts, that is, they are selected independently. These are the conditions under which this situation would be a binomial experiment.
So the correct answers are:
For each part selected, the probability of a defective part being produced must be 0.04.
The parts must be selected independently.
