They vegans disks the e 901826x over 17283
Answer:
Ration is an ordered pair of numbers that show a comparison between two things.
To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient
![\frac{254.34}{3.1415} = 80.95](https://tex.z-dn.net/?f=%5Cfrac%7B254.34%7D%7B3.1415%7D%20%3D%20%2080.95%20)
![\sqrt{80.95} = 8.99](https://tex.z-dn.net/?f=%5Csqrt%7B80.95%7D%20%3D%208.99%20)
That is the radius now just times that by 2 so 2 x 8.99 = 17.98
Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18
Answer:
The measure of smaller angle = 45°
Step-by-step explanation:
Finding the unknown angle
Ratio of the supplementary angles = 3 :1
The angles are 3x , x
Supplementary angles add up to 180°
3x + x = 180
4x = 180
x = 180 ÷ 4
x = 45°
3x = 3*45 = 135°
Answer:
(14, 22)
Explanation:
The amount of time that customers have to wait for their food is normally distributed with:
![undefined](https://tex.z-dn.net/?f=undefined)
• Mean = 18 minutes
,
• Standard deviation = 4 minutes.
The Empirical Rule
For normal distributions, the empirical rule states that:
• 68% of observed data points will lie inside one standard deviation of the mean.
,
• 95% will fall within two standard deviations
,
• 99.7% will occur within three standard deviations.
By the empirical rule, 68% of observed data points will lie inside one standard deviation of the mean.
Therefore, the interval of minutes that the middle 68% of customers have to wait is:
![(\mu-\sigma,\mu+\sigma)=(18-4,18+4)=(14,22)](https://tex.z-dn.net/?f=%28%5Cmu-%5Csigma%2C%5Cmu%2B%5Csigma%29%3D%2818-4%2C18%2B4%29%3D%2814%2C22%29)
The interval is (14, 22).
