A=1/2 B×h
285=1/2×B×15
B=38 feet, so the base of the triangle is 38 feet. Hope it help!
<em>when we solve the equation it will become
x</em>² + 9x<em>= 0
now here a = 1 , b = 9 and c = 0
by using quaderatic formula
x = -b +,-</em>√<em>b </em>²<em>- 4ac / 2a ( 2a is divided by all terms )
by putting values
x = - 9 +,</em><em>- </em>√<em>81 / 2(1) ( </em>√<em>81 = 9)</em><em>
x = -9 + 9 / 2 and x = -9 -9 /2
x = 0 and x = -18 /2 = -9
now there are two values for x one is- 9 and other is 0
so we put -9 as the value of x then answer will be zero..</em>
Answer: B. 0.4772
Step-by-step explanation:
Given : The mean time : ![\mu=64\text{ minutes}](https://tex.z-dn.net/?f=%5Cmu%3D64%5Ctext%7B%20minutes%7D)
Standard deviation : ![\sigma=18\text{minutes}](https://tex.z-dn.net/?f=%5Csigma%3D18%5Ctext%7Bminutes%7D)
Let X be the service time of a randomly selected customer.
Assuming a normal distribution, the value of z-score is given by :-
![z=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
For x = 64
![z=\dfrac{64-64}{18}=0](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B64-64%7D%7B18%7D%3D0)
For x = 100
![z=\dfrac{100-64}{18}=2](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B100-64%7D%7B18%7D%3D2)
The p-value =![P(64](https://tex.z-dn.net/?f=P%2864%3Cx%3C100%29%3DP%280%3Cz%3C2%29)
![P(z](https://tex.z-dn.net/?f=P%28z%3C2%29-P%28z%3C0%29%3D0.9772498-0.5%3D0.4772498%5Capprox0.4772)
Hence, the probability that a randomly chosen customer experiences service done between 64 and 100 minutes = 0.4772
