Answer:
Step-by-step explanation:
For clarity, you need to mark exponents with ^ and parentheses.
You would write the choices A and B as x^(2/5) and x^(5/2), respectively.
Answer:
9/26
Step-by-step explanation:
Im sorry, but probablity is quite hard to explain, but I'll try my best. So what you know is that there are a total of 26 students right? Out of these 25, 14 have at least a cat, and 7 have at least a dog. But 5 of them have a cat and a dog. This means that 14-5, and 7-5, are for only a cat and only a dog respectively. So, people with only a cat don't have a dog, meaning that 14-5, which is 9 people only have a cat. Therefore, out of the 25 people, only 9 don't have a dog, making the probablitly 9/25.
:)))))))))))))))))))))))))))))
We have an equation: 1/?= 25/100
Cross multiply:
25*?= 1*100
⇒ ?= 1*100/25= 4

Answer:
0 ≤ c ≤ 42
Step-by-step explanation:
The cost to take a car across a bay on a ferry is $16.
The ferry has a capacity of 42 cars.
Now, given that the revenue collected is a function of the number of cars, c.
R(c) = 16c .......... (1)
As the maximum capacity of the ferry is 42 and the number of cars can not be negative but can be zero.
So, the domain of the function (1) will be 0 ≤ c ≤ 42 (Answer)
