The answer is 36in because that’s the pathagreom you need to use to find the answer
Hey there! :D
When a fraction is still divisible by a number, then it is not in it's simplest form.
For example, 3/6.
I know for a fact that 6/3=2 <== 3 is also divisible by itself.
3/6 (3/3=1) (6/6=1)
1/2 <== simplest form.
Try the same with 2/4.
4 is divisible by 2.
4/2= 2
2/2=1
1/2 is the simplest form.
I hope this helps!

Answer:
61 commuters must be randomly selected to estimate the mean driving time of Chicago commuters.
Step-by-step explanation:
Given : We want 95% confidence that the sample mean is within 3 minutes of the population mean, and the population standard deviation is known to be 12 minutes.
To find : How many commuters must be randomly selected to estimate the mean driving time of Chicago commuters?
Solution :
At 95% confidence the z-value is z=1.96
The sample mean is within 3 minutes of the population mean i.e. margin of error is E=3 minutes
The population standard deviation is s=12 minutes
n is the number of sample
The formula of margin of error is given by,

Substitute the value in the formula,




Squaring both side,

Therefore, 61 commuters must be randomly selected to estimate the mean driving time of Chicago commuters.
Decimal- A number that has a digit in the tenths place, hundredths place, and/ or beyond.
In the given question, it is given that
ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.
And we have to find the value of tan B.
And tangent of any angle is equal to the ratio of vertical by horizontal. That is

And that's the required missing ratio for tan B .
