Answer:
The four possible outcomes are:
- skirt 1, white
- skirt 1, black
- skirt 2, white
- skirt 2, black
Step-by-step explanation:
Skirt 1 can be white or black (two outcomes). Skirt 2 can be white or black (two outcomes). Therefore, there are four possible outcomes.
Answer: 475.59 meters .
Step-by-step explanation:
The correct equation is the following:
For this exercise you need to use the Quadratic formula:
![x = \frac{-b\±\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-b%5C%C2%B1%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
In this case you can identify that the values of "a", "b" and "c" are:
![a=-0.02\\\\b=9.5\\\\c=5.6](https://tex.z-dn.net/?f=a%3D-0.02%5C%5C%5C%5Cb%3D9.5%5C%5C%5C%5Cc%3D5.6)
Now you must substitute these values into the Quadratic formula and then evaluate. You get:
![x=\frac{-9.5\±\sqrt{(9.5)^2-4(-0.02)(5.6)}}{2(-0.02)}\\\\x_1=475.588\\x_2=-0.588](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-9.5%5C%C2%B1%5Csqrt%7B%289.5%29%5E2-4%28-0.02%29%285.6%29%7D%7D%7B2%28-0.02%29%7D%5C%5C%5C%5Cx_1%3D475.588%5C%5Cx_2%3D-0.588)
Choose the positive one and round it to the nearest hundreth:
![x_1\approx 475.59](https://tex.z-dn.net/?f=x_1%5Capprox%20475.59)
Answer:
Minimum - 8.1 inches
Maximum - 8.35 inches
Step-by-step explanation:
The specifications for manufacturing a steel rod stipulate that the length must be 8.225 ± 0.125 inches.
This means that the minimum length must not be 0.125 inches less than 8.225 inches and the maximum length must not be 0.125 inches greater than 8.225 inches.
The minimum length is therefore:
8.225 - 0.125 = 8.1 inches
The maximum length is therefore:
8.225 + 0.125 = 8.35 inches
