Draw four boxes. Put five balloons in one box with the characters in them and write 1/4 under that box. Then draw five balloons in the other boxes, then draw one big box with the total amount of balloons in them.
Answer:
40% (option C)
Step-by-step explanation:
To find the answer, divide the number of events played in other towns by the total number of performances the band did.
Applying this:
12 / (18 + 12) =
12 / 30 =
2 / 5 =
40%
The answer is C, 40%
Answer:
[ 0.0584, 1.0416 ]
Step-by-step explanation:
Data provided in the question:
sample size, n = 200
Number of defective components = 20
thus,
p = 
= 0.1
Now,
Confidence interval for p is given as:
⇒ p ± 
here, z = 1.96 for 95% confidence interval
therefore,
⇒ 0.1 ± 
or
⇒ 0.1 ± 0.0416
or
confidence interval = [ 0.1 - 0.0416, 0.1 + 0.0416 ]
or
confidence interval = [ 0.0584, 1.0416 ]
In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.
