Step-by-step explanation:
I got this by subtracting 15 by 100 and got 75. This means 75% chose purple. Then you take 75% of 240 and that's your answer
Using variable concepts, it is found that the amounts of time that different surgical procedures take at hospital is continuous.
<h3>What are continuous and discrete variables?</h3>
- Continuous variables: Can assume decimal values.
- Discrete variables: Assume only countable values, such as 0, 1, 2, 3, ...
In this problem, the amounts of time that different surgical procedures take at hospital can be decimal, for example 10.5 minutes, hence it is a continuous variable.

Answer:
Option B) There is a 3 percent increase in the savings account each year.
Step-by-step explanation:
we have

This is a exponential function of the form

where
M(x) represent the amount of money in a saving account
x represent the number of years
a is the original deposit (y-intercept)
b is the base
r is the rate or percent increase

The percent increase per year is the base of the exponential function decreased by 1.
so

In this problem we have
---> original deposit

Therefore
The percent increase per year is 3%
Answer: 170
Step-by-step explanation:
We can set up simultaneous equations such that:
E = R+400
E - 60 = 3R
Solving gives R = 170 and E =570
