Answer:
$11.99
Step-by-step explanation:
19.98x.4=7.99
19.98-7.99=11.99
<span>Yes, this would be considered a function of time elapsed. To be a function, there needs to be exactly a one-to-one relationship between the variables. At any one time (elapsed since midnight), there is exactly one value for the number of calories burned.</span>
Answer:
y = 1/4 (x) + 3
Step-by-step explanation:
Slope intercept y = mx + b
In this case x - 4y= -12
4y = x + 12
y = 1/4 (x) + 3
Answer:
See below
Step-by-step explanation:
Think: They want us to make a box-o-gram (histogram and box-whisker-plot combo).
Identify: They gave us the information we need and we know that health care varies in each state, so that affects the life longevity and also different imcomes affect the care people resceive. We will make the box-o-gram after ordering the data appropriately.
Do: After ordering the numbers from least to greatest, we make calculations for the medians and mean. Here are the answers:
Least: 75 (Need to round up for this)
Greatest: 83 (Need to round up)
Q1: 90.2 (Got this by adding the two numbers of the upper half of data and dividing by 2)
Median/mean: 80.2 (Average of the data)
Q3: 85 (Rounded. Got this by adding the two numbers of the middle half of data and dividing by 2)
Answer:
A: 75
B: 80.2
C: 90.2
D: 85
E: 83
Yes, this makes sense since the data on the box-o-gram fall within the data given in the chart at the top of the worksheet.
Answer:
0.2348 = 23.48% probability that four will have used the e-ticket check-in kiosk to obtain boarding passes.
Step-by-step explanation:
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:

In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this question:
Population of 280, which means that 
112 use e-ticket check-in kiosk, which means that 
Sample of eight passengers means that 
Find the approximate hypergeometric probability that four will have used the e-ticket check-in kiosk to obtain boarding passes.
This is P(X = 4). So


0.2348 = 23.48% probability that four will have used the e-ticket check-in kiosk to obtain boarding passes.
